Zero discharge of waste water at Corradi, PCA

PCA designed a tailor-made water purification system for Corradi that combines a vacuum evaporator with an ion exchanger in a closed circuit. This results in a zero discharge of waste water.

iron removal installation at Barry Callebaut, PCA water

Iron-rich groundwater caused problems during the production process at Barry Callebaut. Our iron removal installation solves these problems in 3 phases. You can read about them here.

process water treatment Citrique

Citrique switches from groundwater to surface water with the help of PCA. Thanks to our tailor-made water treatment plant, they not only benefit financially, but also ecologically.

water treatment plant

A well-known customer contacted PCA for the construction and assembly of a new water treatment installation. Smart systems wanted to double its production and counted on us to deliver an installation capable of purifying 4 m3/h of waste water.


waste water treatment

PCA has provided a new and comprehensive waste water treatment for the AluK plant located in Chepstow (Wales). The new water treatment plant was necessary because of the addition of a lacquering line with chemical pre-treatment within the company. The result is a fully automated and sustainable waste water treatment plant which is capable of purifying 9m3/h of waste water

extrusion die cleaning

The extrusion of aluminium requires regular cleaning of the dies. Cleaning of the dies involves two steps. First, the dies are immersed in a heated solution of NaOH for a certain period of time. During this process, the aluminum that is present will dissolve and thus the die is cleaned.

At AGC’s facility in Seneffe it was important to have demineralised water available at a consistent quality. In the past, the demineralised water was produced with a duplex ion-exchanger.

For the construction of their new pre-treatment line (vertical SAT tunnel + immersion booths) a considerable flow rate of demineralised water was required as well as a large wastewater treatment. Both challenges were entirely in-house developed, produced and delivered by PCA.

When building a new line for the chemical pre-treatment and powder coating of aluminium profiles, the company Wilms (Meerhout) chose PCA to handle its water management. The objective was to eliminate any waste water.

plc waterbehandeling

PCA developped 8 mobile pilot installations. With these pilote installations Vlakwa can offer small & medium companies and the agri- & horticultural sector a temporary watertreatment installation. Vlakwa can research with these installations how to diminish the water consumption and respect the environmental directions.
