SWIMMING POOL FILTER:

Swimming pool filters consist of a large tank, made of fiberglass, concrete or metal, containing a thick bed of special-grade sand, which has a squares shape. During filtering operation, dirty water from the pool comes in through the filter's inlet pipe, which leads to the water distribution head inside the tank. While gravity pulls the water down through the sand, the tiny sand particles catch any dirt and debris. At the bottom of the tank, the filtered water flows through the pick-up unit and out the outlet pipe.

Over time, the collected dirt and debris in the sand slows down the water flow. Pressure gauges at the filter inlet and outlet give the pool custodian an idea of the blockage level inside. If gauges show much greater pressure on the inlet pipe than the outlet pipe, the custodian knows there's a lot of collected debris in the sand. This means it's time to backwash the filter. To backwash, the custodian adjusts a number of valves to redirect the water flow & closes the return pipe leading to the pool and opens the drainage pipe, which leads to the sewer system. Adjusts a valve at the filter to connect the pipe from the pump to the outlet pipe and connect the drainage pipe to the inlet pipe. With this arrangement, water from the pump pushes up through the sand, dislodging the dirt and debris. At the top of the filter tank, the dirty water flows out through the inlet pipe and into the sewer.
