The automatic polyelectrolyte preparation unit (UAP), Salher brand, is a compact device to prepare, mature and dose the polyelectrolyte solution continuously and automatically. This equipment is especially designed to flocculate the wastewater to facilitate the solid-liquid separation. It can be used in the urban and industrial wastewater treatment, during the physical-chemical treatment, but also in the sludge treatment to improve the filter press efficiency.
It consists of a GFRP cylindrical tank with a granulated powder polyelectrolyte volumetric dispenser, a low level product sensor in the hopper, a premix nozzle in AISI 304, a filling and mixing solenoid valve, an hydrostatic transmitter to monitor the levels of operation, a polyelectrolyte mixing agitator, a flowmeter with analog output in the filling point, a granulated polyelectrolyte hopper with a capacity of 25 liters.
