Things to know when using a sand filter;
The most important aspects of a sand filter are the contact surface between water and sand and the height of sand in the filter. Before feeding sand into the filter, the half of the filter capacity must be filled with water in order to prevent any damage to the sprinkler located at the bottom of the filter.
Otherwise, any broken or displaced sprinkler may lead the sand available in the filter to be fed into the pool or the feed line to be filled with sand. When filling the filter with sand, the particle size of the sand used must be between 1.2 and 3mm from the bottom to the end of mid-level, and between 0.7 and 1.2mm at the top level. It is recommended to reduce the water flow rate as much as possible in order to keep the particles in the filter. When the sand fill is completed, the level of sand must be 10cm below the level of top distribution pipe. Otherwise, a certain amount of sand would be discharged during reverse washing process.
