Our filling areas and waste water technology

Our core competencies include the planning, construction, and installation of separator systems for hazardous media. As a specialist in the German Water Management Act (Wasserhaushaltsgesetz, or WHG), we provide comprehensive support for your company, from preliminary planning to acceptance. This includes the manufacture of separators, manholes, sumps, and surfaces with building authority approval for the collection of water-contaminating liquids and fast, inexpensive rehabilitation with proven sealing and joint systems or GRP manhole chambers in accordance with regulations.

Gasoline separators (Class II) and coalescence separators (Class I)

In the flow direction, separators for mineral light liquids according to DIN 1999-100/EN 858, Parts 1 and 2 consist of the sludge trap, oil separator or gasoline separator, coalescence separator, and sampling chamber functional areas.

In the oil separator or gasoline separator, the mineral light materials separate from the waste water due to their lower density and rise to the surface, where they form a floating layer which must be removed professionally at the appropriate filling level. In coalescence separators, small oil droplets that are not separated are also deposited on an oil-friendly carrier material and combine to form a large oil droplet (coalescence). This droplet dissolves, floats, and can therefore be separated. A sludge trap is placed upstream of the oil or gasoline separator. Solids in the wastewater such as sand and sludge collect in the trap.

Our many years of experience in the area of filling areas and waste water technology allow us to carry out all required tests on your systems. In accordance with DIN 1999-100 in conjunction with EN 858 Parts 1 and 2, light liquid and grease separators must be regularly emptied, serviced, and checked for leaks in accordance with DIN 4040-100. We provide you with all necessary official documentation for the general inspections required by law, including the leakage test, which should take place every five years (in water protection areas, every two and a half years).
