Dosing of Activated Carbon Powder

Dosing system for the dust-free dosing of powdered activated carbon (PAC) to eliminate all organic impurities from drinking and waste water.

Dosing directly from 60 l drum. Production of a weak suspension to be conveyed to the filters by a venturi nozzle. Water supply from behind the filter, dosing directly
into a reaction tank or the suction side of the filter pump.
