RO water purifier
This 5 stage reverse osmosis system from CWR Environmental is NSF certified and has several unique features including a tough TFC membrane, which removes more contaminants than other water treatment systems.
Single-piece manifold eliminates many hose connections for greater flow. This system produces 50 gallons/day of high-quality, pure, great-tasting drinking water. Reduces the following contaminants: calcium, sodium, magnesium, perchlorate, potassium, manganese, iron, aluminum, copper, cadmium, silver, mercury, chloride, ammonium, bromide, cyanide, sulfate, nitrate, borate, fluoride, chromate, lead, radioactivity, polyphosphate, orthophosphate, silica, and boron.
HOW REVERSE OSMOSIS WATER TREATMENT WORKS: Osmosis is the process of water passing through a semi-permeable membrane to balance the concentration of contaminants on each side of the membrane. A semi-permeable membrane is a barrier that will pass some particles, pure water, for example, but not other particles such as arsenic and lead. Reverse osmosis uses a semi-permeable membrane. However, by applying pressure across the membrane, it concentrates contaminants (like a strainer does) on one side of the membrane, producing crystal clear water on the other. Consequently, RO systems produce both pure drinking water and waste water that is flushed from the system. This reverse osmosis system also utilizes carbon block filtration technology and can therefore provide a higher quality drinking water than systems that rely only on carbon filtration.
Compact design for kitchen installation with easy connect fittings. 4.0 gallon metal storage tank. Single-piece manifold eliminates many hose connections for greater flow. Double O-ring design housing.
Operational Requirements: The following operational parameters appear on page 4 of the product manual. (1) 40-80 PSI operation pressure. PSI less than 80 requires a pressure regulator. (2) Hardness should not exceed 10 grains per gallon (or 170 ppm). Excessive hardness will shorten membrane life. (3) RO water should not be run through copper tubing, as the purity of the water will leach copper and cause an objectionable taste in the water and may cause pin holes.
Consists of the following filters. Stage 1 sediment filter (recommended change 6 months); this 5-micron sediment filter traps sediment and particulate matter such as dirt, silt, and rust that affect the taste and appearance of your water. Stage 2 and Stage 3 carbon filter (recommended change 6 months); these 5-micron carbon block filters help reduce chlorine and other chemicals/contaminants that cause bad taste and odor. Stage 4 membrane (recommended change 1 year); the RO membrane is the workhorse of the system. This semi-permeable membrane takes out total dissolved solids, sodium, heavy metals, and cysts such as giardia and cryptosporidium. Stage 5 post carbon filter (recommended change 6-12 months); the final stage is an in-line granular activated carbon. This filter is used as a final polishing filter. Entire system is NSF certified (DHS certified in California).
