Long service life - at least 10 years. Annual loss of filtering material is less than 2%
Low bulk density and low backwash velocity allow significant savings on the extraction and preparation of wash water and its further disposal. In some cases, savings compared to sand filters reach up to 40%
FERARRIUM can work with aeration and all types of oxidizers: ozone, sodium hypochlorite, potassium permanganate, etc.
Starts working at pH ≥ 6.5
Increases water pH by 0.5-1.5 units upon start-up, ensuring more effective iron removal;
Does not form biofilm on the surface of the sorbent granules
Has weak coagulating properties, effective for reducing residual aluminum concentrations
Does not require chemical regeneration, simple backwashing with water is sufficient
High dirt-holding capacity, allowing for extended periods between backwashes while guaranteeing water quality with iron content below 0.2 mg/l and minimal pressure drop
Allows increasing the productivity of sand-loaded filters due to higher filtration rates
Is not additionally treated with chemically active coatings based on manganese or other catalytically active metals, which eliminates the risk of failure when these surfaces are depleted or washed off
Helps reduce operating costs when replacing quartz sand with FERARRIUM
Can be used in non-pressurized filtration stations
