Tetra® Denite® from Severn Trent Services is a proven filtration technology used in the denitrification process. As both a bioreactor and effluent filter, the Tetra Denite system combines deep bed filtration and fixed-film biological denitrification to achieve a high level of process synergy. Simultaneous removal of total suspended solids and effluent NO3-N of less than 1 ppm allows facilities to achieve 3 ppm total nitrogen or less.

Paper Facility Increases Efficiency With Filter Rehabilitation
By Leopold -- A Xylem Brand
The Biron mill located in Wisconsin Rapids, Wisconsin produces approximately 370,000 tons of paper each year. The process engineers at the mill were looking for increased capacity and consistent water quality.


Stinkin' Drinkin' Water No More: Oxidation/Filtration Removes Hydrogen Sulfide
By AdEdge Water Technologies, LLC
AdEdge Water Technologies, LLC was contacted by Aqua Utilities Florida to provide a hydrogen sulfide removal system for the Lake Josephine Community located in Highlands County, Florida.

Why Every Utility Should Promote Conservation
At first glance, promoting conservation would seem like a poor financial decision for utilities to make. Less water use equals less money right? Not always.
