HOW IT WORKS

The is a unique upflow floating media clarifier that converts raw water from a river or dam into World Health Organization standard drinking water. The Purification plant consists of chemical dosing pumps, an air blower, the Cubic Clarifier unit and a chlorination unit.

Pre-treated raw water to be clarified is pumped in through the nlet (1) pipe into the Inlet Chamber (2) of the vessel. The water flows through the Diffuser Plate (3) and up through the Filter Media (4) where the coagulated particles are trapped. Clean ater enters into the Outlet Chamber (6) and overflows from the top of the vessel through the Outlet Manifold (7) and Clean Water Control Valve(8) to the Clean Water Storage Facility (9).

STANDARD FEATURES

     STANDARD FEATURES

    1. Clarification Cycle:
    Pre-treated raw water to be clarified is pumped in through the bottom of the vessel which flows up through the media where the coagulated particles are trapped. Clean water overflows from the top of the vessel to the clean water storage facility.

    2. Scour Cycle:
    Once the media is saturated with coagulated dirt, the flush cycle is initiated. The inlet valve (multi-unit) or pump (single unit) is closed or switched off. The chemical dosing pumps are switched off. The scour/air valve is opened to allow an air flow to scour the floating media. This cycle is normally 2 minutes.

    3. Flush Cycle:
    The air valve is switched off and the flush valve opened to allow for drainage of the sludge from the vessel (plus minus 3 to 5 minutes). The flush valve is closed.

    4. Rinse Cycle:
    The pre-treated raw water is allowed to flow into the bottom of the vessel as in the clarification cycle. The rinse valve is opened allowing the vessel to fill and overflow . The rinse valve is closed allowing the for 2 to 3 minutes clean water to overflow to storage facility. the clear water
    The complete Flush and Rinse cycle should last for to 10 to 16 minutes.
