Description

1 WATER TREATIVIENT SYSTEM CONIPRI SI NG A WHEELWASHI NG ARRANGEIVIENT AND |\/IETHOD THEREOF TECHNI CAL Fl ELD The present disclosure relates to water recycling. Furthermore, thepresent disclosure relates to water treatment system for removingcontaminants from contaminated water. l\/loreover, the presentdisclosure also relates to method of treating contaminated water for removing contaminants thereof.

BACKGROUN D Generally, wheel cleaning devices are present in automobilewashing facilities such as motor vehicle laundries. The wheels of avehicle are commonly washed and cleaned for (i) smoothfunctioning of the vehicle and (ii) before the wheels are stored forfuture usages, such as while storing winter wheels, that are beingreplaced with summer wheels in a vehicle (car). Usually, in theconventional wheel cleaning devices, the wheels are washed usingwater (including various types of granules such as plastic) ora water spray for flushing out the contaminants (such asparticles from the car brakes, sand and salt from the road, particles released from the road surfacing and the like).

However, such conventional wheel cleaning devices encountermultiple technical problems. One such problem with theconventional wheel cleaning devices is that after the cleansingof the wheel, the contaminated water is discharged into adrainage system coupled to the wheel cleaning devices. Thecontaminants in the discharged contaminated water often containsharmful elements that causes pollution, namely water pollution, tothe environment. Furthermore, with the growing stringent rules to curb pollution the discharging of contaminated water in a 2 public sewerage system is avoided. Currently, the conventionalwheel cleaning devices had been improvised to refrain fromdischarging contaminated water. ln such wheel cleaningdevices, the contaminants are made to sediment at the bottomof a vessel that holds the water containing the contaminants. lnsuch wheel cleaning devices, the contaminants that sediment atthe bottom of the vessel needs to be removed manually afterdraining out the water. However, such process can becumbersome as the process is performed manually. l\/loreover,since the process is performed manually, so the process can be time consuming and can be prone to human error.

Therefore, in light of the foregoing discussion, there exists a needto overcome the aforementioned drawbacks associated with the conventional wheel cleaning devices. ln a published patent document DE19914289A1 (DRESTER AB;“New Process and Assembly to Clean Vehicle Wheels”), there isdescribed a process of cleaning a cleaning fluid for cleaning vehiclewheels, in a cleaning device in which the fluid is recirculated. Thecleaning fluid has granules and these granules are separated fromthe fluid. The cleaning fluid is then introduced in flocculation tanktogether with flocculating agent and liberating particulate matterand the cleaning fluid is filtered and re-used in the main process.Flocculation is performed in the flocculation tank until smallimpurities and dissolved im purities are flocculated to aggregates.The cleaning liquid with these aggregates are passed through afilter device in which the aggregates are separated from thecleaning liquid and the cleaning liquid cleaned by the aggregates is passed to a drain system or back to the cleaning device.

Optionally, the housing can include one ormore components for removing contaminants from thecontaminated water discharged from the wheel washingarrangement that includes the hard sediment of waste particles,and a mixture of particles and water above the hard sediment of waste particles.

Optionally, the water treating arrangement comprises at least onewater level sensor for monitoring and regulating a water level inthe wheel washing arrangement. For example, the wheel washingarrangement may operate for a predefined/ fixed amount of water,i.e. the amount of water that can be contained by the wheelwashing arrangement, such as 80 liters, 90 liters, 100 liters andthe like. Further, the water treating arrangement comprise a pipearranged with such at least one water level sensor for monitoringand regulating a water level in the wheel washing arrangement.Specifically, the pipe of the water treating arrangement isconnected to the channel, that drains out the contaminated waterfrom the water washing arrangement. l\/loreover, the pipe isarranged on the channel prior to liquid pumping device arranged on the channel.

Optionally, the at least one water level sensor is operable todetermine a maximum level of water in the wheel washingarrangement. lt will be appreciated that the at least one waterlevel sensor arranged on the pipe is fluidically or operativelycoupled to the contaminated water to be received in the pipe forsensing a water level (namely the level of contaminated water)inside the pipe, and thereby monitoring and regulating the water level in the wheel washing arrangement. Beneficially, the at least 14 one water level sensor determining the maximum water level inthe pipe is operable to identify an event wherein the washingarrangement discharges contaminated water that is accumulatedupon cleaning of wheels of the vehicles. Optionally, the watertreating arrangement includes an additional water level sensor,arranged on the pipe, for determining a minimum level of water inthe wheel washing arrangement. lt will be appreciated that theadditional water level sensor is arranged on the pipe at a lowerlevel or height as compared to the at least one water level sensor,operable to sense the maximum water level in the pipe. ln otherwords, the at least one water level sensor and the additional waterlevel sensor are positioned at two different positions suitable fordetermining the maximum and the minimum water level in thepipe, i.e. in the wheel washing arrangement. l\/loreover, theadditional water level sensor is operable to identify an eventwherein amount of the contaminated water is minimum, i.e. thewashing arrangement contains a negligible amount of contaminated water to be discharged.

Alternatively, the least one water level sensor and the additionalwater level sensor for monitoring the maximum and minimumlevel of water in the wheel washing arrangement can be arrangedwithin the wheel washing arrangement. Optionally, the least onewater level sensor and the additional water level sensor can bepositioned in any part of the wheel washing arrangement that issuitable for determining the maximum and minimum level of waterin the wheel washing arrangement. Furthermore, the at least onewater level sensor and the additional water level sensor arepositioned at two different positions suitable for determining themaximum and the minimum water level in the wheel washingarrangement. ln an example, the at least one water level sensor may be positioned at a higher position than the additional water level sensor to determine the maximum and minimum level of water in the wheel washing arrangement.

Optionally, the at least one water level sensor that is operable todetermine the maximum level of water accumulated in the wheelwashing arrangement, can be operatively coupled to the liquidpumping device or the vacuum ejector for providing flow of thecontaminated water from the wheel washing arrangement into thewater treating arrangement. Optionally, the liquid pumping deviceor the vacuum ejector can regulate or cease the operation ofproviding flow of the contaminated water from the wheel washingarrangement into the water treating arrangement based on thesensory signal received from the at least one water level sensor.ln an example, the sensory signal from the at least one water levelsensor may indicate that the contaminated water accumulated inthe wheel washing arrangement has reached a maximum level. lnsuch event, the liquid pumping device or the vacuum ejector mayregulate the operation of providing flow of the contaminated waterfrom the wheel washing arrangement into the water treatingarrangement. ln an example, the sensory signal from theadditional water level sensor may indicate that the washingarrangement contains a negligible amount of contaminated water(i.e. minimum level). ln such event, the liquid pumping device orthe vacuum ejector may cease the operation of providing flow ofthe contaminated water from the wheel washing arrangement intothe water treating arrangement. Optionally, the liquid pumpingdevice or the vacuum ejector is operable to pump out the volumeof contaminated water that is between the maximum andminimum level in the wheel washing arrangement. lt will beappreciated that the minimum level of contaminated water refersto a quantity of the contaminated water that is com paratively less than the maximum level of contaminated water sensed by the at 16least one water level sensor. Therefore, the at least one waterlevel sensor enables the continuous discharge of contaminatedwater from the wheel washing arrangement. Beneficially, thecontinuous discharge of contaminated water from the wheelwashing arrangement enables the wheel washing arrangement to operate ceaselessly for cleaning the wheels.

The water treating arrangement com prises the flocculation cham berfor allowing removal of the contaminants from contaminated waterby flocculation. The flocculation chamber is an enclosed space orcavity wherein contaminated water is flocculated. Specifically, theflocculation chamber is a tank and/or a cabinet that allows forflocculation of the contaminants in the contaminated water.Furthermore, the flocculation chamber includes an inlet connectedto the channel that allows for the flow of contaminated water intothe flocculation chamber. l\/loreover, the inlet connected to thechannel is positioned at an upper portion of the flocculationchamber, so that when the contaminated water is pumped intothe flocculation chamber the accumulation of the contaminatedwater starts from the bottom portion of the flocculation chamber.Alternatively, the contaminated water can be sucked into theflocculation chamber using the vacuum ejector. The vacuumejector may be operable to generate a vacuum pressure in theflocculation chamber to initiate a flow of the contaminated waterfrom the wheel washing arrangement to the flocculation chamber.ln such an event the channel positioned at the bottom portion ofthe washing arrangement drains out the contaminated water toflow through the inlet formed at the upper portion of theflocculation chamber. Furthermore, the term “f/occulation” as usedherein, refers to the addition of a flocculant, such as a chemicalagent (e.g., acid treatment), to a solution (such as the contaminated water) to remove one or more suspended insoluble 17or soluble impurities therein. The chemical agent must be addedto the solution at a concentration which allows for spontaneousformation of insoluble aggregates which can be removed fromthe contaminated water via typical solid-liquid separation methods.

The water treating arrangement com prises the flocculation powderregulation device coupled to the flocculation chamber forintroducing a controlled amount of flocculation powder into theflocculation chamber. The flocculation powder regulation device isa unit operatively coupled to the flocculation chamber that holds asupply of flocculation powder to be discharged in a controlledamount into the contaminated water accumulated in theflocculation chamber. Furthermore, the flocculation powderregulation device is an autonomous electronic device that isconfigured to release a specific amount of flocculation powder intothe contaminated water. The specific amount of flocculationpowder to be released can be preprogramed into the flocculationpowder regulation device. lt will be appreciated that the specificamount of flocculation powder released into the contaminated watercorresponds to an amount of contaminated water accumulated inthe flocculation chamber. The amount of contaminated water inthe flocculation chamber is determined using sensors. Optionally,the sensors may be connected to the flocculation powderregulation device. Furthermore, the flocculation powder regulationdevice may be configured to release the specific amount offlocculation powder based on sensory signals provided by thesensors to the flocculation powder regulation device. Alternatively,the flocculation powder regulation device can be configured torelease controlled amount of flocculation powder into theflocculation chamber before the contaminated water fills the flocculation chamber. ln an example, the controlled amount of 18flocculation powder is released into the flocculation chamber bythe flocculation powder regulation device, and thereafter, theflocculation chamber is filled with the contaminated waterdischarged from the wheel washing arrangement. Subsequently,the flocks may be formed in the contaminated water. Optionally,the specific amount of flocculation powder to be discharged intothe flocculation chamber before the contaminated water fills theflocculation cham ber is preprogramed into the flocculation powderregulation device corresponds to the amount of contaminated water that can be housed in the flocculation chamber.

Optionally, the flocculation chamber includes at least two waterlevel sensors to determine the level of contaminated wateraccumulated in the flocculation chamber. Furthermore, the atleast two water level sensors are positioned in suitable positionswithin the flocculation chamber to appropriately identify the levelof contaminated water in the flocculation chamber. For example,one of the at least two water level sensors are positioned at theupper portion of the flocculation chamber to determine amaximum level of contaminated water in the flocculation cham ber.Furthermore, the sensor (positioned at the upper portion of theflocculation chamber) can send a sensory signal to the liquidpumping device or the vacuum ejector to stop operating therein,i.e. to suspend the flow of contaminated water into the flocculationchamber. Thereafter, in such example, the sensor (positioned atthe upper portion of the flocculation chamber) may send anothersensory signal to the flocculation powder regulation device.Furthermore, the sensory signal to the flocculation powderregulation device may instruct the flocculation powder regulationdevice to release the specific amount of flocculation powder ontothe contaminated water. Furthermore, in another example, another one of the at least two water level sensors are positioned 19at the bottom portion of the flocculation Chamber to determine aminimum level of contaminated water in the flocculation Chamber.I\/|oreover, in such event wherein the minimum level ofcontaminated water is determined in the flocculation chamber, asensory signal may be send by the sensor (positioned at thebottom portion of the flocculation chamber) to the liquid pumpingdevice or the vacuum ejector to resume operation therein, i.e. therecommence the flow of contaminated water into the flocculationchamber. Optionally, one of the at least two water level sensorsthat is operable to determine a maximum level of contaminatedwater in the flocculation chamber, can be communicativelyconnected to the liquid pumping device or the vacuum ejector.Furthermore, the liquid pumping device or the vacuum ejector isconfigured to regulate or cease the operation of providing flow ofthe contaminated water from the wheel washing arrangement intothe water treating arrangement, based on the sensory signalreceived from the water level sensorsthat is operableto determinethe maximum level of contaminated water in the flocculationchamber. Optionally, the liquid pumping device or the vacuumejector is configured to pump out the contaminated water from thewheel washing arrangement and discharge the contaminatedwater into the flocculation chamber of the water treatingarrangement, in an event wherein the at least one water levelsensor provides the liquid pumping device or the vacuum ejectora sensory signal indicating that the contaminated water level inthe wheel washing arrangement has reached a maximum level,and one water level sensors configured to determine themaximum level of contaminated water in the flocculation chamberprovides the liquid pumping device or the vacuum ejector asensory signal indicating that the contaminated water level in theflocculation chamber has not reached maximum level therein.

Therefore, the amount of water to be discharged from the wheel washing arrangement may be controlled by one of the at least twowater level sensors that is operable to determine a maximum level of contaminated water in the flocculation cham ber.

Furthermore, insuch example, the mixer may initiate the function of blending thecontaminated water and the flocculation powder, in an eventwherein the water level sensors positioned at the upper portion ofthe flocculation chamber identifies that the amount of thecontaminated water accumulated in the flocculation chamber hasreached the maximum level. lt will be appreciated that, in such event the flocculation powder regulation device may release the 21controlled amount of flocculation powder into the contaminatedwater. Furthermore, in such example, the mixer may cease thefunction of blending the contaminated water and the flocculationpowder, in an event wherein the water level sensors positioned atthe bottom portion of the flocculation chamber identifies that anamount of the contaminated water accumulated in the flocculation cham ber has reached a minimum level.

Additionally, the water treating arrangement further includes ameans for agitation. ln an example, means for agitation may be ablower device that is operable to blow air into the flocculationpowder mixed contaminated water. Optionally, the means foragitation, namely the blower is operatively coupled to theflocculation chamber. Furthermore, the blower may beautonomous electronic device that is configured to initiate and/orcease functioning based on received sensory signals. For example,the blower may initiate blowing of air into the contaminated waterupon receiving a sensory signal from the water level sensorspositioned at the upper portion of the flocculation chamber thatidentifies the amount of the contaminated water accumulated inthe flocculation chamber has reached a maximum level. lt may beappreciated that the blower initiate blowing of air into thecontaminated water in the event wherein the mixer initiates thefunction of blending the contaminated water and the flocculationpowder. ln another example, the blower may cease blowing of airinto the contaminated water upon receiving a sensory signal fromthe water level sensors positioned at the bottom portion of theflocculation chamber that the amount of the contaminated wateraccumulated in the flocculation chamber has reached a minimumlevel. Optionally, the blower includes a timer that can determinethe initiation and/or ceasing of the function of the blower, i.e. the blower may be operable to blow air into the contaminated water 22for blending the flocculation powder for a predefine period of timeand/or blow air into the contaminated water for blendingrepeatedly for predefined time period. Beneficially, the means foragitation provides efficient blend of the flocculation powder and the contaminated water.

Furthermore, the flocculation chamber includes a water outlet.The water outlet of the flocculation chamber provides an openingfor the flocculation powder mixed contaminated water to flow outof the flocculation chamber. Optionally, the system furthercomprises a p|ura|ity of valves for regulating the flow ofcontaminated water. The water outlet of the flocculation chamberincludes a valve of the p|ura|ity of valves for regulating the flow ofcontaminated water. The valve is operatively coupled to the wateroutlet and can control the flow of contaminated water out of theflocculation chamber. Optionally, the valve may be connected toan electronic control unit. Furthermore, the electronic control unitis operable to monitor and control the opening and closing of thevalve. Furthermore, the electronic control unit is operable tocontrol the opening and closing of the valve based on the sensorysignals received from the water level sensors positioned at the upper and bottom portions of the flocculation cham ber.

Optionally, the system is further operable to monitor opening andclosing of valves. Specifically, the electronic control unitconnected to the valve that is further operatively coupled to thewater outlet, is operable to monitor the opening and a closing ofthe valve. Furthermore, the electronic control unit is operable tomonitor the time periods associated with the opening and closingof the valves. For example, the electronic control unit may monitorthe time period for which the valve is open, the time periodafter which the valve opens after being closed, the time period for which the valve has not opened (caused by a contaminant 23 obstructing the functioning of the valve) and the like. Optionally,system further is operable to monitor functioning of the flocculationchamber. The electronic control unit monitors the functioning ofthe flocculation chamber based on the opening and a closing ofvalve. For example, in an event wherein the opening and closingof the valve associated to the water outlet is irregular (i.e. thetime period for which the valve is open and/or the time periodafter which the valve opens after being closed is not regular), theelectronic control unit may consider the flocculation chamber isnot working properly. ln such example, the electronic control unitmay be operable to generate an alert in the form an alarmingsound, light or a combination of both (an alarming soundaccompanied with a flickering light). ln another example, in anevent wherein the opening and closing of the valve associated tothe water outlet is regular (i.e. the time period for which the valveis open and/or the time period after which the valve opens afterbeing closed is regular), the electronic control unit may consider the flocculation cham ber is working properly.

The water treating arrangement comprises the filtration tankoperatively coupled to the flocculation chamber for filtering theflocculation powder mixed contaminated water discharged throughthe water outlet.
