    Dewatering Unit

    FD Petrol explosion proof 20ft containerized automatic dosing unit is a high stand chemical dosing unit, solids and liquids separation and chemical dosing process is continuous, closed and stable.PLC system automatic warning for lack of polymers and avoid dry running. Through coagulants and flocculants technology to make the ultra fine particles (≤2microns) aggregate into large mass ,then separate by dewatering centrifuge.
