Sewerage systems - Import export

Given that Ferric alum is powder that does not burn when it is exposed to fire, it is commonly used in firefighting foams. When applied at the base of fire, it forms a blanket that prevents the combusting materials from accessing oxygen that is required for them to keep burning. Some water treatment firms use the salt for treatment of water. During the treatment of water, the electrons in the water hydrolyze fast forming combinations with various metal elements in water. They form slats that sediment at the base of the container and can be filtered away. Unlike many water purification agents, Ferric alum can work at very low temperature. This makes it ideal for water treatment during fall and winter seasons. The same compound works well in disinfecting and treatment of sewerage systems. It combines with organic matter and deals with the resulting odor.

A more economic solution for an environmentally sound condensate management is the decentralised oil-water separation directly at the source. Condensate which was processed with ÖWAMAT can be directly introduced as cleaned water into the sewerage system. The devices have a national technical approval and do not require a permit according to the law on water. In addition, the ÖWAMAT oil-water separators do not create any energy costs, boast enormous filter service lives and can be retrofitted into older systems without difficulty.
