Other TDS contaminants reduced by up to 98%: Aluminum, Ammonium, Bicarbonate, Calcium, Chlorine, Chloromines, Chromate, Cyanide, Ferro cyanide, Iron, Magnesium, Mercury, Manganese, Phosphate, Silicate, Silver, Sodium, Strontium, Sulfate, Sulfite, Thiosulfate, Zinc.

*Please note: RO systems provide effective filtration for Arsenic 5 (AS5), not Arsenic 3 (AS3).

Chlorination converts AS3 into AS5. Is your well chlorinated?

Depending on the distribution of the arsenic species in your water chlorination might be required to bring the overal Aresenic load below the 10 ppb recommended level. For example you have 12ppb of arsenic, if 5ppb are AS5 and 7ppb are AS3, then the RO should bring down the AS5 level sufficient to bring the overall level below the 10ppb EPA safe level. Please use an arsenic speciation tests to be sure of the exact amounts, and if your water is not chlorinated.

**Nitrate removal is pressure sensitive. Under ideal conditions nitrate reduction of up to 80% is achievable. Consider a booster pump, permeate pump and an inline nitrate filter post-RO to achieve greater nitrate filtration.
