Power plant

Influent water treatment

Pretreat influent water before it enters your plant’s system. Proper influent water monitoring is the first defense to protecting the health of your equipment and preventing corrosion. By properly treating water at this stage, you can reduce costs and treatment within the power and steam generating process.


Steam and power generation

Protect your equipment – from pipes and tubes, to turbines and boilers – by ensuring your water is of the highest quality. Minimize silica levels to prevent turbine blade erosion, and monitor and manage dissolved oxygen (DO) to prevent corrosion.


Cooling water

Ensure heat transfer processes are as efficient as possible by effectively controlling total suspended solids (TSS) to avoid the expense and downtime associated with fouling and mineral buildup that can cause scaling and hazardous operating conditions.


Industrial wastewater

Ensure compliance with all discharge requirements. Our industrial wastewater solutions help you minimize environmental impact and ensure compliance with permits.
