Pool filter service
Most people understand filter as a fundamental component of a swimming pool filtration system. However, many of them are not aware that filters have to be cleaned regularly in order to ensure proper equipment working condition and cleanliness of the pool water. Swimming pools are liable to steady contamination from foreign matter acquired by swimmers, wind, and articles utilized as a part of and around the pool. Filtration is a mechanical procedure of expelling this insoluble matter from swimming pool water. Water clarity is essential for appearance, safety, and hygiene. Filters are universal in pool systems, connected to the circulation system alongside the motors and pumps. As water pumps through the pool’s circulation system, impurities are removed by the filter. The filter itself has no moving parts and is made of simple elements.
There are three main types of filters namely: diatomaceous earth, sand and cartridge filters. Each of these filters has its advantages and disadvantages, and their cleaning process is dependent on the size of the filter and the pool.
A diatomaceous earth filter comprises a tank with a series of fabric covered grids, also known as filter elements. The fabric is covered with a filtration substance media called DE, or diatomaceous earth. DE is the fine, white powder found in huge deposits on the ground. They act as filters by permitting water to pass through while leaving impurities behind. They can filter out microscopic impurities. A filter must be properly sized in order to fit in the pool circulation system. This size is controlled by square footage of surface region of the filter media, which equivalents to the aggregate square footage of the filter elements. A normal channel has eight braces that aggregate to a total 24 to 72 square feet. The filter grids are put into tanks that are 2 to 5 feet high and around 2 feet in breadth. Without the grids, DE would transform into built up mass, when wet, making it impossible for water to pass through.
Sand filters have a diameter 2 to 4 feet and look like huge balls. Older models are housed in metal tanks. The sand in the filter removes our pollutants as the water passes through. The water enters the top or side of the channel through a multiport or cylinder discharge valve and splashes over the sand. The sharp edges of the grains get the impurities. The water is pushed through the laterals and base manifold where it is then channeled out of the filter. A drain pipe is situated at the base of the tank for emptying out the water when needed.
A cartridge filter works in a similar manner as the DE filter except that it does not use a DE. Water enters into the tank which houses at least one round and hollow cartridges of fine mesh material. The mesh of the fabric strains out the pollutants. Cleaning is done by removing the cartridges and washing them unlike in DE, and sand filter where backwashing method is used.
