Cleaning by centrifugal force

With the centrifugal filter technology solid fines are removed from the process water with a centrifugal force which is up to 2417 times higher than the gravity of the earth. Oil and /or extremely fine solids < 1 μm can be removed by adding flocculants. The compound utilized for the finishing operation remains largely in the process water for re-use in the finishing process.

Automatic peeling centrifuge ZA

The PLC-controlled automatic centrifuges ZA 04 and ZA 06 can clean up to 2000 litres of mass finishing process water per hour. The sludge separated in the rotating drum is peeled off into the sludge tank in time adjustable cycles. The modular construction of our ZA model range allows an optimum machine configuration which can be perfectly adapted to customer’s specific requirements. For example, by selection of different sludge and process water tank sizes, cooling systems, additional process water pumps, dosing systems etc.

Limits of application

Centrifuges cannot be used universally. They are not suited for the following mass finishing applications:

• for chemically accelerated and paste processes

• for multi-stage processes with different compounds

• for pickling processes with acid

• for ball burnishing applications
