Royal Talens, a leading manufacturer of artists' paints and hobby paints, moved to a new production site in the industrial zone of Apeldoorn. For the treatment of its industrial wastewater, the company relied on PCA Water.

We designed, supplied and commissioned a complete wastewater treatment installation that treats the wastewater using a physico-chemical process and also handles the dewatering of the resulting sludge.

Royal Talens provided large underground tanks to collect the wastewater. PCA Water installed the mixers in these tanks and laid the piping that connects the wastewater collection to the treatment installation.

From the tanks, the installation pumps approximately 15 m³ of wastewater to the reactor for each new treatment cycle.

Targeted pH correction and flocculation

In the reactor, PCA Water treats the wastewater in several steps.

First, we dose ferric chloride (FeCl₃) to lower the pH to below 3.2. We then add milk of lime to raise the pH to 9.7. These successive pH corrections promote the precipitation of contaminants.

Next, we dose polyelectrolyte (PE). This binds small particles into larger flocs, which settle more easily and are easier to dewater later on.
