After new lower discharge limits for cadmium were introduced, a U.S. metal finishing facility providing aerospace and oil industry services reached out to Evoqua for help. Evoqua conducted treatability testing and filtration analysis, then implemented a selective media ion exchange solution using SCU vessels in a worker/polisher configuration to consistently meet strict ppb-level discharge requirements and restore compliance.

A Minnesota mine reduced copper and cobalt in its discharge using wastewater ion exchange, achieving compliance without chemicals and adapting to seasonal flow increases.

Mobile demineralization units provided high-quality boiler feed water at Norfolk Naval Station, helping maintain U.S. Navy operational readiness.

High-purity water is essential for producing steam that will not scale turbine blades with silica, minerals, and other contaminants. A large power generating company in North America used a competitor's continuous electrodeionization (CEDI) system for that purpose.

In February 2020, the California State Water Resources Control Board announced revised drinking water Response Levels for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in drinking water. The new Response Levels (RLs) were set at 10 parts per trillion (ppt) for PFOA and 40 ppt for PFOS. The previous RL was 70 ppt for a combined total concentration for the two contaminants.

To help companies protect against waterborne infection and disease, Evoqua recently hosted a webinar dedicated to understanding and improving water quality in land-based hatcheries that you can watch here.

A fish process facility in Norway detected Listeria monocytogenes in their facility and contacted Trond Storebø of Naustor Technology, Evoqua’s partner in Norway. Within three weeks, Naustor had acquired one of Evoqua’s new PC Series ozone disinfection systems. The use of ozone has made the products safer, enhanced the shelf-life for the fresh produce and protects the company’s brand.
