In the swimming pool water purification treatment, quartz sand acts as the filter material role. Quartz sand is filled in the sand cylinder, used to purify the filtration water quality. So why clean the quartz sand?
  
First of all, we need to understand the principle of swimming pool filtration. The filter of the swimming pool system is the sand cylinder, in which the filling filter material is quartz sand. Quartz sand itself has high strength, long life, large water treatment, water quality stable and reliable advantages, can remove suspended solids, colloid, silt, rust and other impurities. The pool water flows from the upper end of the sand cylinder into the sand cylinder, through quartz sand filtration, wherein the impurity dirt through the quartz sand interception, adsorption and other functions, is filtered to intercept in the sand cylinder, adsorbed on the quartz sand surface, filtered clean water through the sand cylinder bottom of the pipeline back to the swimming pool use.
  
Due to the filtration of impurities adsorbed on the surface of quartz sand, over time, the surface of the sand will be impurities wrapped, and gradually thickened, when the impurities accumulated to a certain amount of the package, will affect the flow of filtration speed, and lead to the ability of quartz sand water purification gradually weakened, and so on. Therefore, every certain time, to clean the quartz sand, the surface of the impurities removed, so that it restores the ability to clean water.
  
The process of cleaning quartz sand is to backwash the sand cylinder. To use a dedicated sand cylinder cleaning agent, cleaning. Cleaning and then filtering will restore efficiency. General cleaning frequency of six months or one year cleaning. can also be determined as appropriate.
