According to the principle of screw sludge dewatering machine, we developed a new type of sludge thickening equipment-screw sludge thickener as the demand of market. Screw sludge thickener inherits advantages of screw sludge dewatering machine, like: automatic continuous operation, low energy consumption, high efficiency, running stable and excellent properties, directly concentrate the sludge in secondary sedimentation tank. This equipment can be used instead of concentrated tank, reduces the area as well as the civil engineering construction cost, and effectively reduce stench and phosphorus release of sludge concentration pool. This equipment can be used as pretreatment of sludge dewatering and depth dewatering equipment.

Fully automated water treatment plant with obliquely-arranged lamellar clarifier, chamber filter press, pressure boosting station, fresh water tank and individually adjustable Siemens PLC with touchscreen display.

Chamber filter presses are designed for filtration and dehydration of already concentrated process water suspensions. The sediment already concentrated in the obliquely-arranged lamellar clarifier is pumped to the chamber filter press by means for further dehydration by means of a special diaphragm pump. The filtrate water drains through a droplet channel during the pressing process and is returned to the production circuit. The particles contained in the process water suspension are retained between the filter cloths. The degree of drying of the filter cakes can be individually adjusted and is monitored by a water sensor.
