Multi Function 870*870 Filter Press for Fertilizer Industry

What is municipal wastewater? It mainly refers to the sewage from domestic wastewater, some industrial waster that allowed to be discharged, and rainwater. For municipal sludge, it's different from industrial sludge. Normally it does not contain toxic elements, such as heavy metal, acid, etc., however, it's very viscous. Additionally, after pretreatment, the solid percentage is very low. So normal chamber type plate filter can not work well and has very lower efficiency. Thus in wastewater treatment plants, namely WTP, they adopt a chamber membrane filter press for sludge dry stack. Because the membrane filter press machine can squeeze the filter cake twice to ensure lower cake moisture. This can greatly save the subsequent sludge processing cost.

While operating a membrane filter press machine, we must pay attention to the following points.

(1)Pressure Difference. The cake squeezing pressure is higher than feed pressure and suggests not too much higher than feed pressure. The more pressure difference, the more deform of membrane plates, then will shorten filter plate's lifespan or even damage plates.

(2)Additionally, after the filtering process finished, before open the filter plates, it strictly must discharge the membrane squeeze pressure in advance. If not, it will also damage membrane filter plates.

Features of municipal wastewater membrane filter press:

• Good dewatering result. The filter cake moisture can reach around 50-60%.

• Filter plate adopts high-pressure membrane filter plates.

• Sludge can be secondarily squeezed so that has higher filtration efficiency.

• The filter press machine is controlled by PLC to save laborers.
