Clean TeQ Water’s BIOCLENS® technology was used to polish nitrate to below 10mg/L for an industrial business park.

Summary

A business park in Europe contained between 3000 and 6400 employees, producing unequal loading and varying nitrate concentration in the wastewater. The effluent from the plant was discharged into a stream which had strict discharge requirements of 5ppm for nitrates. The plant had an average flowrate of 377 m3/day and produced an effluent which consistently meets the 5ppm discharge requirement.
