SULFUR FILTERS

A pungent rotten egg odour and/or black sediment accompanies sulfur or hydrogen sulfide. Sulfur levels dictate the type of treatment that can be used to eliminate this problem. Generally levels of sulfur less than 4 ppm can be removed by either a manganese greensand filter, which uses the chemical potassium permanganate to regenerate, or a chemical-free air injection filter with a mixing tank.

Levels of sulfur exceeding 4 ppm must be treated with a chemical feed system using either chlorine or hydrogen peroxide. The equipment required consists of a chemical feed pump, retention tank and an automatic carbon filter. This is the most effective method of removing high levels of sulfur in your water. As sulfur is a gas, water must be tested on site.
