BioSand Removing Iron
The image shows water inside a BioSand Filter. The water has been pumped in directly from the well and has a very high iron content. The Biosand filter removes nearly all of the iron and provides clean, clear water. See our customer testimonials about this installation.

Iron, Manganese, Sulfur

These three are sometimes known as the "troublesome trio," as they are often found together. The result? Staining on your plumbing fixtures and/or a strong "rotten egg odour" that is detectable down to very low levels. While not considered to have detrimental effects on health, these chemicals can be unsightly and awkward to deal with.

Removing Iron, Manganese, and Sulfur

  • Greensand Filtration uses potassium permanganate to oxidize the contaminants so that they can be removed by a filter bed
  • BioSand filters is a unique type of slow sand filtration ideal for rural water treatment. Cleaning the slow sand filter does not consume any media and produces virtually no wastewater. BioSand filters have capacities ranging from 20 litres per hour to 600 litres per hour.
  • Oxidation and Filtration uses air, chlorine or ozone to oxidize the contaminants so that they can be removed by a filter bed

All systems have pros and cons are are suited to different installation environments. Contact us for more details. Hydrogen Sulphide is commonly removed via aeration in an unpressurized tank.
