Impression series filters are extremely effective at removing hydrogen sulphide and iron, which are common problems in drinking water. These innovative units use a unique air-injection filtration technology to oxidise the sulphur or iron, which then precipitates so it can be filtered out and removed. Impression series filters are environmentally friendly – no toxic substances are used, as in other systems. The result is refreshing tap water, every time.
Impression series air-charged filters are proven to be effective at removing high levels of sulphur and iron, which are quite often found in drinking water. The filters are used together with other Impression series equipment to provide a complete water treatment solution. The filter media bed works together with the air-filled chamber to oxidise and filter out sulphur and iron. The system regenerates using ordinary water to backwash the system and remove sulphur, iron and other contaminants.
