Advanced solutions for industrial water treatment

At PCA Water, we design, build and install robust water treatment installations that contribute to the continuity and efficiency of your production processes.

With decades of experience in industrial engineering, we translate complex water challenges into reliable systems that comply with the applicable discharge and quality standards.

feed water

Treatment of incoming water to the required process or demineralised water quality.

Treated water

Wastewater treatment, water reuse and zero liquid discharge (ZLD).

Die cleaning

Customised process technology for the extrusion industry.

Feed water and process quality systems

At PCA Water, we treat the available incoming water to achieve the water quality required for your production process. Depending on the composition of the water and the specific requirements of your application, we apply a range of treatment techniques. These allow us to remove or reduce dissolved salts, hardness, suspended solids and organic contaminants, among other things. In this way, we tailor the water quality to the needs of your production process and help protect your installations and equipment.

Reverse osmosis & nanofiltration (RO & NF)

Membrane technology for demineralisation and ion removal. From nanofiltration to high-recovery reverse osmosis, we tailor the installation to the required water quality and maximise water recovery wherever possible.

Ultrafiltration (UF)

A robust mechanical membrane separation process for removing suspended solids, macromolecules and microbiological contaminants. Ideal as a stand-alone treatment for surface water or as a reliable pretreatment step to effectively protect downstream membrane systems against biofouling.

Ion exchange

Removal of ions using high-quality cation and anion exchange resins. A proven and highly reliable technology for softening, dealkalisation and condensate polishing under varying flow rates.

Electrodeionisation (EDI)

Continuous demineralisation without chemical regeneration, producing ultrapure water (UPW) for critical applications. By combining ion exchange membranes, resins and an electric field, the resins are regenerated continuously, without periodic acid or caustic regeneration.

Filtration techniques

Using a range of filtration techniques, we remove suspended solids, fine particles and organic contaminants from water. Depending on the composition of the water and the required water quality, we apply techniques such as multimedia filtration, sand filtration, fine filtration and activated carbon filtration. In this way, we tailor the treatment to your application and help protect downstream installations.

Wastewater treatment for discharge or reuse

When wastewater streams are complex, carry high pollutant loads or must meet strict discharge limits, we combine chemical, mechanical and thermal treatment techniques into a robust, complete solution. This allows us to maximise water recovery, minimise residual streams and – where technically and economically feasible – achieve zero liquid discharge (ZLD).

Vacuum evaporator

A vacuum evaporator is used to highly concentrate wastewater streams and reduce the residual volume requiring disposal. By evaporating water under vacuum, the water is separated from the dissolved substances. Depending on its quality, the distillate produced can be reused in the production process. This enables water reuse and leaves only a limited volume of concentrated residual stream.

Physico-chemical treatment

The foundation of effective wastewater treatment through precisely dosed coagulation, neutralisation and flocculation. Our installations ensure optimal floc formation and rapid settling, essential for the suspended solids,...

Acid recovery & iron removal

Sustainably extending the service life of process baths in the surface treatment industry, reducing your chemical consumption and neutralisation costs. We efficiently separate dissolved iron from valuable acids using diffusion dialysis or targeted crystallisation, resulting in substantial savings on chemical purchasing and neutralisation costs.

Dewatering

Volume and cost reduction of the sludge streams produced by your water treatment plant. Using automatic chamber filter presses or belt filters, we increase the dry solids content of the sludge and reduce both the volume to be disposed of and the associated processing costs.

Reverse osmosis & nanofiltration (RO & NF)

Membrane technology for removing dissolved salts, metals and other contaminants from industrial wastewater. From selective nanofiltration to advanced purification with reverse osmosis, we tailor the installation to the composition of the wastewater and the required water quality, with particular attention to water reuse.

Ultrafiltration (UF)

An efficient membrane technology for removing suspended solids, colloids, macromolecules and microbiological contaminants from wastewater. It can be used both as a stand-alone treatment step and as pretreatment to protect subsequent treatment processes and membrane systems against fouling.

Engineered solutions: die cleaning

In addition to conventional water treatment installations, PCA Water also develops customised systems for industrial applications.

One example is our automated cleaning and rinsing systems for dies in the extrusion industry. These systems remove aluminium residues from the dies by means of a controlled cleaning process. By automating the cleaning process, we reduce the need for manual handling and create a safer working environment.
