Nijhuis Saur Industries

We help industries secure reliable, high-quality process water — while protecting the environment and reducing costs. Whether you're manufacturing electronics, refining chemicals, or producing food, your process water needs to be consistent, compliant, and efficient. That's why we treat every drop.

Your challenges

In industrial operations, process water is essential — but also challenging to manage. Common issues include:

  • Variations in source water quality that affect production outcome.

  • Strict regulations for process water discharge, reuse, and purity.

  • High operational costs tied to water usage and treatment.

  • Contamination from chemicals, heavy metals, and biological agents.

  • Pressure to reduce freshwater intake and environmental impact.

What is process water?

Process water in general

Process water is water used in industrial processes for manufacturing, cleaning, cooling, or as a raw material. Its quality depends on the specific application, ranging from general cleaning water to highly purified forms. Common types of process water include cooling water, boiler feed water, rinsing water, and water used directly in product formulations.

How can NSI meet your needs?

At NSI, we’re committed to giving water the value it deserves. Our approach combines technical expertise with our purpose-driven #missionwater strategy:

  • Reduce water consumption through smart reuse and recycling

  • Remove contaminants that compromise product quality and compliance

  • Reuse treated water in cleaning, cooling, and manufacturing processes

  • Recover resources like heat, chemicals, and nutrients where possible

Whether you need high-purity water for production or stable feedwater for cooling, we build robust, integrated systems tailored to your operations.
