Increasingly stringent wastewater requirements, urbanization and increased demand for water recycling equipment have made MBR membrane technology a leading innovation in wastewater treatment.

In the classical treatment, the biomass is separated from the purified water by sedimentation of the contaminants in a decanting basin. The disadvantages of this system are that it results in a lower amount of dry substance and a lower quality of the effluent. At the same time it needs a larger installation area.

During the biological treatment and ultrafiltration process, activated sludge concentration increases continuously and, in order to ensure a constant concentration of the activated sludge, it is necessary to discharge excess sludge from the MBR module. The suspended solids probe measures the sludge concentration of the module and when it indicates the excess of 10-12 g / l, the excess sludge exhaust pump starts and feeds the sludge storage tank and then the dewatering unit, where it reduces Its humidity.

The treated effluent is discharged into a pool permeate and hence, a small portion of the treated water is used for washing the ultrafilter membrane (backwash) and the rest is discharged to the outfall. The membrane is washed by pneumatic solenoid valves and is fully automated.

Through MBR technology, the membrane module replaces the secondary decanting step. This physical barrier reduces the space required for construction and increases the quality parameters of the purified water.

Good cost-effectiveness ratio

These are just a few arguments that advocate the choice of MBR technology offered by C & V Water Control.
