Auto-backwashing Filox and Greensand Plus Filters

Whole House Filters for Iron, Hydrogen Sulfide, and Manganese Reduction

Iron is one of the most common elements found in nature, and most groundwaters contain a measurable amount of iron. Iron stains bathtubs, toilets, sinks, and driveways, and it will even stain the side of your house in sufficient concentrations. In addition Iron, Manganese, and Hydrogen Sulfide release unpleasant odors and tastes to your water supply. FILOXTM and Greensand-PIusTM are great solutions to these challenging water quality problems.

Two Media Types

Filox

A non-chemical oxidizing media to reduce Iron, Manganese, and Hydrogen Sulfide.

Greensand-Plus

An enhanced version of the traditional medium to remove iron from water.

Filox system advantages

  • Highest flow rate of any Iron removal media.
  • No oxidizing chemicals are needed for regeneration.
  • High efficiency with 80% manganese dioxide for enhanced performance and capacity.
  • Effective, from 5.0 to 9.0 pH.
  • System is easy to program, with 10 pre-programmed regeneration cycles to optimize water treatment.

Greensand-Plus system advantage

  • Lower backwash requirements.
  • Known saturation capacity.
  • Higher temperatures and differential pressures than traditional Manganese Greensand.
  • Greensand-Plus is also used for radium reduction.
  • User friendly, low maintenance electronic time clock valve.

Note: The use of chemicals and oxidizers, such as chlorine, potassium permanganate, and oxygen may be required for both systems to provide the optimal treatment for Iron. Hydrogen Sulfide and Manganese.

Filox Models

Greensand Plus Models

The maximum contaminant level for iron set by USEPA standards is 0.3 milligrams per liter (ppm) of water. In concentrations above 0.3 ppm, Iron in water can cause staining of fixtures and porcelain, and ruin laundry. A bittersweet astringent taste is detectable at concentrations above 0.5 ppm by many people. Manganese is often found with iron, causes brown, black, and/or tea-colored staining, and imparts asphaltic and oily tastes, above 0.05 ppm. Likewise, Hydrogen Sulfide which is common in water with Manganese causes an irritable rotten egg smell, all these three contaminants are effectively removed by Filox & Greensand-Plus Greensand-PlusTM requires periodic refreshing with a small amount of Potassium Permanganate; see in chemical supplies. Potassium Permanganate can be purchased at your local home improvement store also.
