GalvaCor - Oil and fat removal from degreasing baths
Degreasing is always the first and one of the most important step in every kind of surface treatment. A not well operated degreasing will give problems in the next steps, followed by necessary correcting actions and related extra costs. In order to raise performance of degreasing bathes and to ensure constant quality one has to take out continuously oil from the degreasing bath.

The WTN Galvacor systems with tuned chemistry are perfectly suitable for this task. In general degreasing bathes contain oiland grease-binding surfactants. These long-chain oil-bearing tensides can be separated from free tensides by micro-filtration, the heart of the Galvacor systems. As a result one will get a degreasing solution with a very low oil content.

Operation principle

The system consists of a storage/ separator tank, a pump and a membrane made of degreasing chemicals-resistant material.

The degreasing liquid is pumped into the storage/separator tank via a platefilter system, to separate the solid particles. Next the degreasing is directed through the membrane area with high speed and increased pressure.

The filtrate(clear liquid and free tensides) runs back into the degreasing bath. The oil with bound tensides is lead into the storage/separator tank, where oil is separated from the water and the bound tensides are released by thermo-shock and can be reused again. The oil can be disposed as highly energetic waste.

The WTN Galvacor systems are available in different sizes, single– and double version, depending the materials to be degreased:

Model membrane surface (m2)
Galvacor 3SA 3
Galvacor 5SA 5
Galvacor 7SA 7
Galvacor 10SA 10
Galvacor 20SA 20
