The MicroClear® filter functions according to the "out-in" principle. These filters are completely submerged in the clarification plant's activated sludge and the filtrate is extracted with 0.15 bar negative pressure. Once the filtrate passes through the membrane it moves on through a burl structure in the base plate with practically no pressure to reach the filtrate outlets. Right from the beginning, the even distribution of pressure over the filter plate is of decisive importance to trouble-free operation. If pressure distribution is uneven then certain areas will exhibit high throughput while other areas of the filter's surface remain unused.
"MicroClear® Full Surface Distribution" technology ensures that every square centimetre of the membrane is used – evenly – from the first day until the day of the next basic cleaning. A unique air bubble cleansing phenomena removes deposits from the membrane in a purely physical manner, without any repeated backflushing of chlorinated chemicals.
