DESCRIPTION
The UFMC is a unique Upflow floating media clarifier that converts raw waterfrom a river or dam into World Health Organization standard drinking water. Iron is successfully removed with the system as well.
The purification plant consists of chemical dosing pumps, an air blower, theunit and a chlorination unit. Pre-treated raw water to be clarified is pumped in through the inlet pipe (1) into the Inletchamber(2) of the vessel.
The water flows through the Diffuser Plate (3) and up throughthe Filter media (4) where the coagulated particles are trapped. Clean Water enters into the outlet chamber (5) 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).

OPERATING CYCLES
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.
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 drain 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 to drain. The rinse valve is closed allowing the clean water to overflow to storage facility. The complete Flush and Rinse cycle should last for plus minus 9 to 12 minutes.
