We understand the growing importance of reliable and sustainable industrial water management. Whether it's for manufacturing, chemical processing, or energy production, managing industrial water efficiently is essential for maintaining productivity, reducing environmental impact, and ensuring regulatory compliance.

By treating industrial water on-site, companies can minimize costs, improve process stability, and recover valuable resources while meeting environmental goals.

What is industrial water and wastewater?

Industrial water

Industrial water refers to water used in industrial processes such as manufacturing, energy generation, chemical processing, and food production. Unlike domestic water, which is intended for human consumption and sanitation, industrial water is specifically used for production activities, equipment cooling, cleaning, processing raw materials, and other operational tasks in an industrial setting.

Your challenges

Businesses face increasing pressure to manage industrial water sustainably, while keeping operational costs low. Key challenges include:

  • Treating and reusing complex industrial water and wastewater streams.
  • Meeting strict discharge and water reuse regulations in industrial water applications.
  • Minimizing freshwater intake by maximizing industrial water recycling and recovery.
  • Addressing contamination in industrial water from chemicals, heavy metals, and micropollutants.
  • Ensuring consistent water quality in mission-critical industrial water processes.

How can NSI meet your needs?

We’re committed to giving industrial water the value it deserves. Our approach is based on sustainability, innovation, and circular water use:

  • Design and build complete industrial water treatment and wastewater recovery systems.
  • Integrate reuse and recycling strategies tailored to your footprint.
  • Recover resources such as heat, energy, and raw materials from treatment processes.
  • Achieve zero-liquid discharge (ZLD) and minimize environmental impact of water usage.
  • Monitor and optimize operations using digital twins and smart industrial water management tools.
