Dosing of Activated Carbon Powder

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

Dosing directly from Big-Bag or silo. CARBODOS produces a suspension that is either conveyed directly to the filter or bassin at a low back pressure or to a buffer
tank from where the suspension is dosed. The level of the buffer tank is controlled automatically.
