Functioning

The dirty liquid, channelled through a distributor that prevents turbolences, comes to the nonwoven fabric. A turbine creates the vacuum sucking air from the inside of the drum on which the fabric slides. The difference of pressure between the chamber and the outside, allows the liquid to flows through the fabric. Once the vacuum chamber is reached, the liquid flows to the collecting tank and is put back into circulation by a delivery pump. The vacuum effect increases the flow rate, allows to increase the filtration panel thickness and sucking air to obtain a dry and compact waste material. The dirty particles accumulate onto the fabric building up an additional layer of high quality that improves its filtration degree. The solid particles that built up clog the filter causing the raising of the liquid. When the set maximum level is reached, the floating switch starts off the drum rotation. The dirty fabric is conveyed into a dust bin whereas the clean fabric is ready again for filtration. An automatic device for the fabric winding (optional) separates the sludges. Thanks to the short fabric advancing, only a small part of it is renewed so as to take advantage from the optimization of the fabric consumption and the better filtration result as the liquid goes through the layer created. The fabric advancing stages do not interrupt the filtration process. An end-of-roll mirco switch signals the end of the fabric roll.
