Continuous filter press
Continuous Belt Press Filter The continuous belt press filter is a reliable, efficient and cost-effective equipment used for the dewatering of sludge in wastewater treatment plants. The continuous belt press filter operates on a continuous cycle, with no interruption or stoppage. The cycle consists ......
Deep Cone Thickener
Deep cone thickeners (also known as deep cone paste thickeners) are mechanical thickeners with a high side wall and a steep feeding throat that has a cone angle slightly steeper than the cone angle of sedimentation tanks. Deep cone thickeners are used mostly for thickening non-Settling solids in l......
flocculant
Flocculation is a process of introducing flocculants into water in order to cause suspended solids to aggregate into a larger mass. Flocculants are typically polyelectrolytes that carry either a positive or a negative charge when dissolved in water, and can act as a bridge to bring particles toget......
