Sulfur

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.

Chlorination Systems

A chlorination system can consist of the following:

  • Chlorinator: A chemical feed pump designed to inject a predetermined level of chlorine into the water. Chlorine will kill bacteria and oxidize high levels of iron, manganese, and sulfur.
  • Retention Tank: This tank is used to insure contact time for a proper bacteria kill, and/or time to completely oxidize iron and sulfur.
  • Multimedia Filters: Used for removal of oxidized iron, and sulfur.
  • Carbon Filter: Removes chlorine and/or organics which may be present in water.
