Purification works - Import export

The Sewerage division of TRBA Group specialises in the installation of sewers, collectors, inspection chambers and pumping stations that contribute to the sanitation of both urban and rural areas. These works enable wastewater to flow to the treatment plants designed and built together with our electromechanical partners.

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.

IFA Technology designs and implements the right exhaust air purification system for every pollutant. Exhaust air scrubbers are used for exhaust air purification of exhaust air streams from industrial processes loaded with harmful gas. These exhaust air purification systems work according to the principle of absorption and separate pollutants present in the exhaust air in the liquid phase. Depending on the substance, pollutants are either physically dissolved or chemically bound by the addition of lye and/or acid. We consider your individual requirements and build customised exhaust air purification systems for you. With the companies Wessel-Umwelttechnik and Airprotech we have competent partners within the Deurotech Group at our side to develop special and complex systems for exhaust air purification.
