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
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.
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.
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.
