Look into and safeguard any a piece of filtration membrane and other parts, easy to maintenance, when amount of parts is inadequate, component allows few dress
The use of diaphragm and flow guiding disc without influenceing DTRO membrane modules, this is that other forms membrane module is unable to reach.
5）Filtration membrane renewal cost is low
Any single part of the utility model component internal allows to be individually replaced, filtration fraction by multiple filtration membranes and
Flow guiding disc is assembled, and single replacing can be carried out when filtration membrane need to be changed, and may continue to for the good diaphragm of strainability
Using, this, which at utmost reduces, changes film cost, and this is that the other forms membrane module such as rolling, doughnut is unable to reach,
For example entirely membrane module it can only be changed when rolled film the quality problems such as patch, local leakage occurs or more need to renew film.
6）Application field is extensive
Can be used in the processing of percolate, Treatment of Coking Effluent, power plant effluent zero-emission, gas production wastewater treatment, coal
Chemical wastewater treatment, recovery separation, acid recovery, alkali collection, heavy metal recovery, desalinization, mobile water purification, urban drinking water are answered
First aid is helped, field operation, the field such as camp.
