four. Phase: Membrane processes / Nanofiltration From the fourth and closing cleaning stage, membrane and filter processes are made use of. In part, this purification phase is combined with the chemical processes of precipitation and flocculation.
[18] It is also commonly used for the treatment of other sorts of wastewater. Solids which might be denser than water will accumulate at The underside of quiescent settling basins. Extra complicated clarifiers even have skimmers to concurrently get rid of floating grease for instance soap scum and solids including feathers, wood chips, or condoms.
