In order to guarantee uncontaminated and suitable water in topping-up on water based coolant filtration units, we propose to treat the water which will guarantee a longer life due to its low chloride and other harmful contents, and lower pH.

Nevertheless, the liquid must be maintained in good condition taking into account of external pollutants.

On washing applications, for example, solutions exist to reduce the foreign oil content by ultrafiltration, centrifugation or more naturally by coalescence plate oil separator. The best suited technology is determined according to the exact type of contaminant found in the product.

Finally, as these products reach the end of their life cycle, they can be recycled by evaporation or separated by ultrafiltration with de-oiling pre-treatment stations after being placed in storage tanks.

All these installations are automatically controlled and designed for low maintenance.
