PROCESS WATER RECYCLING

For ecological and economic reasons recycling of the process water in connection with industrial manufacturing operations is highly desirable. The principle of the 2-phase separation of solids/liquids with centrifugal force has become the standard

for modern process water cleaning systems, which ensures process stability. Powerful systems, combined with sophisticated process technology, allow for a wide range of applications, reaching well beyond just mass finishing processes.

How it works

The dirty water, contaminated with solid particles, is transferred directly from the mass finishing machine to the centrifuge or through a pump station (lifting station). A pre-screen collects larger contaminants at the inlet of the collecting tank. The premature settlement of the solid particles to the bottom of the collecting tank is prevented with a built-in electric stirrer. The dirty water is continuously supplied to the rotating aluminum drum of the centrifuge with a compressed air diaphragm pump. The high centrifugal force created by a rotational drum speed of up to 3,000 RPM ensures that even very small and lightweight solid particles are deposited as solid sludge on the drum wall.

The cleaned liquid is picked up by a collecting tube and returned to the mass finishing machine (or other users). After a preset time the sludge can be removed from the drum by simply lifting the specially designed polyurethane sludge basked out of the drum. In automatic centrifuges the sludge is mechanically removed with a peeling knife scraping it from the drum wall. Depending on the required water volume multiple mass finishing machines can be connected to one process water recycling system.
