The Pureflow Filtration Div. of California Environmental Controls, Inc., was founded in 1973 when they designed and sold their first Arsenic, Iron and Manganese removal pressure filtration system.  This 1,500 gpm system introduced the Pureflow process that included PM-100 proprietary filter media.  PM-100 is a permanent, highly adsorptive, catalytic media that does not require regeneration (or KMnO4 feed) and offers flow rates up to 15 gpm / sq. ft. of filter media.  They have continued to expand our heavy metal removal processes, and in addition to PM-100, they also provide non-proprietary media (e.g. PM-200, Manganese Dioxide [MnO2]).  PM-200 is a permanent catalytic adsorptive filter media, with a high Manganese content, that will also remove heavy metals such as Arsenic, Iron, Manganese, Radium / Uranium and Hydrogen Sulfide.  In addition to permanent media systems, we provide Titanium based disposable media systems for the removal of Arsenic from drinking water supplies.

Pureflow Filtration also manufactures water treatment systems for the removal of Fluoride (with PM-500 Activated Alumina media), and Perchlorate (with PM-600 ion exchange resin) from drinking water supplies.  Pureflow Filtration has pressure filter installations in the United States and Canada with flow rates ranging from 25 gpm to 9,000 gpm, and gravity filter installations in Mexico with flow rates ranging from 2,700 gpm to 15,000 gpm.  All Pureflow Filtration media meet NSF / ANSI Standard 61.
