PAC dosing device is one kind of coagulant dosing device, PAC is also called polyaluminium chloride, and the solid product is light yellow or brown grain or powder. In the process of using, the liquid should be diluted according to the proportion of 10-15% and added to the dosing point through dosing equipment. So PAC dosing device in the process of using easy to plug the filter and metering pumps or piping system, PAC dosing device manufactured by our company added a backwashing system in the pump inlet, regular or stop the pump before automatic backwashing for several minutes, and the security of metering pump pipeline system clean, very good solution the blockage phenomenon, eliminating the need for complicated artificial cleaning work, this unique design won customers.

So PAC coagulant dosing device working principle and process is what kind of?

Working principle

PAC is a kind of inorganic polymer coagulant. Mainly by compressing double layer, adsorption and charge neutralization, adsorption bridging, sediment trap mechanism, so that the water micro suspended particles andcolloidaliondestabilization, aggregation, coagulation, flocculation, sedimentation, purifying treatment effect.

Technological process

PAC dosing device is mainly composed of a flocculant solution tank, metering pump, electric control cabinet, mixer, magnetic level gauge, safety valve, pressure valve, flow calibration column, pulse damper, Y filter, ball valve, drain valve, pressure gauge, piping and accessories, equipment installation, equipment cable base and support platform etc.. Solid dosage solution kits, then proportionally adding tap water by stirring and dissolving, flocculant metering pump added pipeline mixer or dosing. The control can be done manually or automatically according to the output signal of the upper system.
