Compact Band Filter

The turbulent zone at the band inlet produces an arc-filter effect, which keeps the filter paper free of dirt and hence permeable at this point. The particles settle in the non-turbulent area of the filter reservoir, to form a cake. The cake itself acts as an additional filter media layer, thereby enhancing the filtration effect even further. A pool forms gradually as the particle deposits build up on the paper. Depending on the type of filter, high hydrostatic pressure difference produced in this way, helps to ensure that the filter paper is used with maximum efficiency.

As the open area of media reduces, the maximum preset level in the tank is reached, geared motor switches on and pulls new filter paper from the reel, without any interruption to the filtration process. The filtration from the fresh media paper starts, level in the tank sinks and the conveyor stops automatically. At the same time the sludge and used filter paper are discharged on the other end of the tank. If required a push button switch may also be used, for manually operating the geared motor and to bring the fresh paper forward, as desired by operator time to time.

Individual sludge scrapers are fitted between the wheels, to handle larger volumes of sludges. These drivers remove all sludge and coarse chips, without damaging the filter paper. The entire filtration process runs fully automatic. The diameter of the paper roll is also monitored by a special sensor and a signal is given when the paper is low, all kinds of customized automation is possible.

Various grades of Filter papers are available, to achieve the desired filtration effect. Filtration can be further improved, for fine dirt application by using pre-coat techniques.
