Excessive dirt, silt, particulate matter, etc can be a major problem in commercial, industrial or even domestic use. Turbid water is not only unpleasant to look at, it can be unsafe to drink and reduce life of pumps & pump seals, valves and other equipment. Drinking water regulations require the water to have turbidity less than 1 NTU, above which it is considered unsafe for drinking. Commercial washing machines and dishwashers cannot operate with dirty turbid water.
While cartridge filters are used to filter low to medium amounts of dirt, excessively high loads of dirt can plug them up in a short period of time, leading to increased costs of replacement and downtime.
Where excessive dirt conditions exist, Rainfresh EBWFE automatic back-washable filters provide excellent turbidity reduction without the need to change filters. These filters consist of a processed and graded rare natural mineral that has unique filtration properties. Typically, water gets filtered down to 5 micron nominal.
After a pre-set amount of time, the system automatically undergoes a backwash cycle wherein all the trapped dirt/sediment goes to drain and the system is ready for use again. There are no replacement filters in this system and is virtually maintenance free.
