The right chemical treatment for your water process

The composition and quality of water have a significant impact on the performance of industrial installations. Corrosion, scale deposits, biological growth and other contaminants can disrupt operations and increase water and energy consumption.

PCA supplies water treatment chemicals for a wide range of industrial applications. Based on the water quality, the type of installation and the process conditions, we determine which chemical treatment is suitable. In doing so, we pay attention to both product selection and correct dosing and monitoring.

In addition to the chemicals themselves, PCA can also provide the dosing installations, measuring equipment and automatic control.

Cooling water treatment

Limiting corrosion, deposits and biological growth

In open and closed cooling circuits, corrosion, scale deposits and microbiological growth can affect the performance of the installation. In open cooling towers in particular, evaporation causes the concentration of dissolved salts to rise. In addition, temperature and the nutrients present can promote the growth of bacteria and biofilm.

PCA Water offers complete cooling water treatment solutions, from the supply of suitable chemicals to the installation of automatic dosing and monitoring systems.

Our dosing and monitoring installations ensure controlled chemical dosing and make it possible to continuously monitor key water quality parameters and adjust the treatment where necessary.

When selecting the treatment, we take into account the type of cooling circuit, the make-up water quality, the operating temperatures and the required cycles of concentration. We also look at ways to reduce blowdown and chemical consumption.

Boiler water treatment

Protection of steam and hot water systems

In steam and hot water boilers, dissolved salts, residual hardness and gases such as oxygen can cause deposits and corrosion. Deposits on heat transfer surfaces reduce heat transfer, while corrosion can damage boilers, pipework and condensate systems.

PCA Water offers both chemical treatment products and automatic dosing and monitoring installations for efficient boiler water treatment. Depending on the application, oxygen scavengers, alkalinity regulators, phosphate-based products and condensate protection agents can be used, among others.

Our dosing and monitoring systems allow chemicals to be dosed accurately and key process parameters to be monitored. This helps to maintain stable water quality and reliable operation of the installation.

Product selection and dosing are tailored to the feed water quality, the boiler pressure and the specific operating conditions.

RO water treatment

Limiting scaling and membrane fouling

In reverse osmosis (RO), dissolved salts are retained by the membranes and concentrated in the concentrate stream. As a result, sparingly soluble salts can precipitate on the membrane surface, which can lead to scaling and reduced membrane performance.

To limit this risk, a suitable antiscalant can be dosed. PCA determines product selection and dosing based on the water analysis, the recovery of the installation and the expected composition of the concentrate.

We also supply cleaning chemicals for RO and other membrane installations. Depending on the nature of the fouling, acidic or alkaline cleaning products can be used.

Scrubber water treatment

Limiting deposits and optimising water consumption

In industrial gas scrubbers, the circulating scrubber water absorbs contaminants from the air stream. As a result, dissolved salts and other substances can gradually build up, which can lead to deposits and blockages.

To control these concentrations, part of the scrubber water is bled off and replaced with fresh water. In certain applications, appropriate chemical conditioning can limit the formation of deposits, potentially allowing higher cycles of concentration and lower blowdown.

PCA determines which treatment is suitable based on the type of gas scrubber, the components captured and the composition of the circulating scrubber water.

Integrated dosing installations

Dosing tailored to the process

In addition to supplying chemicals, PCA also designs and builds complete dosing installations. These can consist of storage tanks, dosing pumps, pipework, injection points, measuring equipment and automatic control.

Depending on the application, dosing can be linked to process parameters such as flow rate, pH, conductivity or redox potential. This allows the amount of product dosed to be adjusted to the current operating conditions.

In the design, we take into account the chemical resistance of materials, the required dosing capacity, storage conditions and the safe operation and maintenance of the installation.
