Pure water equipment selection and maintenance of the filter

The face of the market a wide range of assortment of pure water equipment, we should be how to choose and maintain water equipment?fabric filter

Strainer by the size of the filtered water, the most common sand filter, non-woven filter filter and PP fiber filter, filter, the nonwoven filter and the length of the PP fiber filter is the most commonly used 10-inch and 20-inch two, as a coarse filter with a pore size of the filter should generally be about 25u.

The role of the coarse filter is to remove suspended impurities larger particle size in water, to avoid these impurities into the activated carbon filters, covering the surface of the activated carbon, the pore structure of activated carbon adsorption of impurities in the water is lost.bag filters

Strainer with the rejection of solid impurities increase the resistance sharply rises, the water flow is gradually decreased. Without timely treatment, can not meet the water flow requirements for follow-up treatment processes. Sand filter, pressure increases to a certain extent after backwash. Backwash some fine sand out of the filter, sand filter should be regularly supplemented with sand, sand after repeated backwash, the degree of fragmentation increases, at the same time each backwash impossible to rinse sand the remaining sludge is gradually increased, the sand will appear the phenomenon of "compaction", you should replace the sand. Non-woven or PP fiber filter, filter pore clogging generally difficult to rinse with water, shall replace the filter on a regular basis.
