What is process water treatment and why is it important?

In modern industrial processes, water is far more than just a working medium – it is a valuable resource used for cooling, cleaning, chemical reactions, and as a working fluid in machinery. The reliable treatment of this water is crucial for productivity, operational safety, and environmental compatibility. Only high-quality process water can optimally protect equipment and simultaneously meet legal requirements.

Process water refers to water used within technical or industrial processes – for example, as cooling water, cleaning water, or operating water in machinery. Its quality directly affects the performance, lifespan, and efficiency of equipment

Contaminated water can lead to:

  • Deposits and biofilm growth
  • Corrosion and increased wear
  • Production disruptions
  • and high maintenance costs

In addition, the European Water Framework Directive prescribes strict limits for the entry of process and wastewater into bodies of water or sewage systems - requirements that modern treatment systems must reliably meet.

A holistic water treatment process pursues two central goals:

  1. Protection and optimization of production
  2. Environmentally sound disposal or reuse of water

How does filtration work, and which filters are used?

Filtration is the heart of every process water treatment system. It removes particles, suspended solids, and other contaminants from the water before it is reused, recycled, or discharged. Different technologies and filter types are used depending on the application.

What are automatic filters?

Automatic filters from Filtration Group are self-cleaning, automated filter systems that ensure consistent water quality, especially in continuous operating processes. Thanks to their integrated backwash function, they require minimal maintenance and allow for uninterrupted operation. Backwash filters play a particularly important role in cooling water treatment by removing coarse dirt particles from river or surface water and ensuring consistently high filtration efficiency through automatic backwashing, which significantly increases the reliability and lifespan of the systems.

What does a basket strainer do?

Basket filters are robust and efficient pre-filters that reliably remove larger solids and particles from process water. They are particularly suitable for protecting downstream filtration systems or sensitive components such as pumps and heat exchangers. Their simple maintenance and high throughput make them an economical solution for minimizing mechanical stress caused by dirt particles.

What advanced technologies are available in water treatment?

In addition to mechanical filters, membrane processes are also used in industrial water treatment to remove the finest impurities and dissolved substances.

  • ultra filtration (UF)
  • nano filtration (NF)
  • reverse osmosis (RO)

These processes enable the production of high-quality process water that can also be used in sensitive applications.

What does a typical application example look like?

In cooling water treatment, Filtration Group's automatic backwash filters protect cooling circuits from deposits and biological contamination. The filters ensure continuous, automated cleaning, thus guaranteeing stable and efficient operation of the cooling systems.

Basket filters are often used as pre-filters to remove larger particles and reduce the load on downstream filter systems.
