Industrial Wastewater Treatment

Treating complex, industrial wastewaters for discharge, recovery, and reuse

Heavy industry, manufacturing, and natural resource-based industries often use large volumes of water and generate wastewaters requiring treatment. Saltworks designs, builds, and operates industrial wastewater treatment plants with modern membrane, chemical, and thermal technologies that economically and reliably treat tough industrial wastewaters.

Industrial Wastewater Management

The first step in managing your industrial wastewater is to define your goals. Do you need to meet discharge requirements, minimize off-site disposal costs, reduce freshwater withdrawal, or achieve reuse targets? Do you need to target problematic contaminants such as metals and ions, achieve minimal or zero liquid discharge, or recover valuable by-products from your wastewater?


Next, know what’s in your water and what (and how much) you need to treat for. Industrial wastewaters can be complex, with variable composition making treatment more challenging. After that comes understanding your options and their economics. Saltworks can help with the entire process — from project discovery and options analysis, to pilot scale testing, all the way to full-scale plant delivery.

What’s in Your Wastewater?

Some of the industrial wastewater components we frequently encounter and can treat for include:

It is important to know the concentrations of components like these in your industrial wastewater and how they vary, as well as the overall flowrate.

Knowing Your Project

Delivering the right wastewater treatment process is not just about treating the waste stream and its components. Often the most reliable and economic solution will combine treatment, recycling, and disposal. Other project concerns may include:

Industrial Wastewater Treatment Options

Saltworks’ water experts will start by reviewing your water chemistry, specific project details, and overall objectives. We will develop a comprehensive options analysis that considers water chemistry, available technologies, treatment and disposal economics, and regulatory requirements.


Our proprietary solutions include advanced chemical, thermal, and membrane systems that work alongside our novel sensor technologies and intelligent controls. We also offer a wide range of technologies through our partners, enabling us to provide a wastewater treatment solution optimized for your specific project.


We can then scale up in whatever way suits you best, including desktop studies and mobile pilot systems that quickly and cost-effectively prove performance at your site or ours. Our full-scale plants are designed, engineered, and manufactured at our own facility, ensuring responsiveness, cost-optimization, and quality assurance from project start to testing, and through to delivery and commissioning. We can also perform in-place upgrades to modernize, automate, or expand your existing wastewater treatment facilities. To learn more about how we treat the toughest waters, see our wastewater treatment articles. To investigate your project’s treatment options, contact our expert industrial wastewater team.

How to Manage Brine Disposal & Treatment

The many options for managing brine, a term for saline wastewater from industrial processes, fall under two categories: brine treatment and brine disposal. Brine treatment involves desalinating the brine for reuse and producing a concentrated brine (lower liquid waste volume), or residual solids (zero liquid discharge).
