  PROCESS OF NATURAL PURIFICATION OF POLLUTED WATER
INDUSTRIAL BY BIO-CONCRETE FILTERS.



  The invention relates to a process for purifying industrial water comprising a pretreatment by natural action of acidic organic sludge on polluted water followed by their filtration through bio-concrete filter elements. This filter device may also be suitable for purification of the less polluted waters of canals and rivers, ponds and lakes or of precipitation.



  Currently, industries use complex chemical and mechanical treatment processes for the purification of their water. Mechanical treatments use sophisticated machinery requiring, in addition to heavy investment, significant maintenance and energy consumption.



  The object of the present invention is to remedy these drawbacks. The invention, as characterized in the claims, solves the problem of pretreating polluted water by simple reaction with organic acid sludge placed in settling tanks, then filtering it by gravity through filtering elements. bio-concrete.



  The advantages obtained thanks to this invention consist essentially in the fact that the more no machine is necessary, the more no chemical is used, the energy consumption is very reduced and the process is entirely natural.



  The invention is set out below in more detail with the aid of drawings representing only one embodiment.



  FIG. 1 represents in plan the installations necessary for the treatment of polluted water in accordance with the present invention FIG. 2 represents a section in principle according to AA in FIG. 1

 <Desc / Clms Page number 2>

 FIG. 3 represents a block made of bio-concrete, a constituent element of the filtering wall 5 in FIG. 1.



  The process includes: * a reinforced concrete buffer tank (2) for the storage of polluted water, optional depending on the flow of water to be treated; * one or more reinforced concrete basins (3) for the pretreatment of polluted water by the action of organic acid sludge, their number depends on the flow of water to be treated; * a gravity filtering basin (4) in reinforced concrete comprising a filtering wall (5) in bio-concrete: * a stepped surface (6) for the oxygenation of the filtered water; * a reinforced concrete collection tank (7) to collect the purified water; * a reinforced concrete buffer tank (8) for the storage of clean water, optional depending on the flow of water to be treated.

REVENDICATIONS 1. Procédé d'épuration des eaux industrielles comprenant un prétraitement par action naturelle de boues organiques acides sur les eaux polluées suivi de leur filtrage au travers d'éléments perforés filtrants en bio-béton. Au départ de la source d'eau polluée (9), celle-ci est stockée dans un bassin tamponCLAIMS 1. Process for the purification of industrial water comprising a pretreatment by the natural action of organic acid sludge on polluted water followed by its filtration through perforated filtering elements made of bio-concrete. From the polluted water source (9), it is stored in a buffer tank (2) Par pompe (1), l'eau polluée est envoyée dans les bassins (3) contenant des boues organiques acides ; leur nombre est fonction du débit des eaux à traiter. Ces bassins sont remplis successivement et vidés dans le même ordre. (2) By pump (1), the polluted water is sent to the tanks (3) containing organic acid sludge; their number depends on the flow of water to be treated. These tanks are successively filled and emptied in the same order. L'eau ayant subi le premier traitement est envoyée par pompe (1) dans le bassin (4). Par filtrage à travers la paroi (5) constituée de blocs en bic-béton, l'eau subit son second traitement. Elle est ensuite oxygénée par chutes successives sur des gradins (6) et est recueillie dans le bassin (7). Par pompe (1), l'eau est ensuite envoyée soit dans un cours d'eau (10), soit dans un bassin tampon (8) avant d'être recyclée vers l'unité de production dans le cas d'une industrie. Périodiquement, les boues acides organiques saturées sont enlevées des bassins de décantation (3) et envoyées vers une unité de déshydratation (11) par évaporation de l'eau contenue dans les boues. Celles- ci peuvent ensuite être recyclées en les utilisant dans la fabncation de matériaux de construction ou envoyées vers une usine de traitement de telles boues (12) 2.  The water having undergone the first treatment is sent by pump (1) to the basin (4). By filtering through the wall (5) made of two-concrete blocks, the water undergoes its second treatment. It is then oxygenated by successive falls on steps (6) and is collected in the basin (7). By pump (1), the water is then sent either to a stream (10) or to a buffer tank (8) before being recycled to the production unit in the case of an industry. Periodically, the saturated organic acid sludge is removed from the settling tanks (3) and sent to a dewatering unit (11) by evaporation of the water contained in the sludge. These can then be recycled using them in the manufacture of building materials or sent to a plant for treating such sludge (12) 2.
