Water treatment for the Energy Industry

Your challenges

Tackling complex water and wastewater challenges across various energy sectors, such as:

Managing high-strength wastewater

Managing high-strength wastewater from biofuel and hydrogen production processes remains a key challenge for many facilities.

Meeting strict discharge requirements

Meeting strict discharge requirements and minimizing water use are critical in upstream oil and gas operations.

Reducing water cost and focus on water stewardship to meet sustainability goals

Reducing water costs and focusing on water stewardship are essential to meet sustainability goals. Reusing wastewater for cleaning purposes and recovering process water from pasteurization lines and cooling towers can support these efforts.

Handling challenging wastewater streams

Handling challenging wastewater streams from refinery and downstream processes requires advanced treatment solutions.

How can NSI meet your needs?

We’re ready to give water the value it deserves in the energy industry. To tackle your challenges, we offer an innovative approach to:

Design, build, and operate water and wastewater treatment systems tailored to energy sector needs.
Recover energy, heat, and valuable by-products from wastewater and sludge.
Integrate circular water concepts for reuse and zero-liquid discharge (ZLD).
Improve water quality for critical processes like steam generation and chemical reactions.
Minimize operational risk through robust, reliable, and scalable solutions.
