Flocculator Tank Maintenance

Running Tank

The pump for the tank can be plugged in on the far side of the plant above the rapid mix. The alum pump is controlled by process controller.

Tube Settlers

Tube settles should be rested at a 60 degree angle on the baffle connections and against the side wall of the tank. When they are connected to the line the should be submerged to fill them with water. The seal between the tube settler and the turbidimeter must be air tight.

Turbidimeters

Turbidmeters should be checked before anytest in the flocculator is run. If they are dirty they should be cleaned with dissolved water and kim wipes. If the turbidimeter reads dessicant, the dessicant needs to be changed. This can be done by unscrewing the lid of the turbidimeter and replacing it. If the line to the turbidimeter is clogged, backwash it. 

Cleaning Tank

The flocculator needs to be cleaned as regularly as flocs start to build up in the tank. A pump and hose for cleaning the tank are next to the flocculator. Waste from the tank must be drained down the sink located in the far left corner of the plant (across from the tank). This is because the sludge contains aluminum compounds. Care should be taken when cleaning the tank- the sink clogs easily and floods the surrounding area. If the sink floods, the wet-vac is the easiest way to clean up the mess.
