Nutrient Removal System That Combines The Denitrification And Filtration Process
Severn Trent Services offers the TETRA® Denite® System for the removal of nitrate-nitrogen (NO3-N) and suspended solids (SS) in a single treatment step. Denite is a fixed-film biological denitrification process that also serves as a deep bed filtration system capable of removing suspended solids to virtually any final effluent requirement. The system integrates well with other plant treatment processes to provide superior total nitrogen (TN) and phosphorous removal.
While the debate rages on as to whether fracking poses a risk to water quality, a new desalination technique addresses two other environmental concerns: water scarcity and greenhouse gas (GHG) emissions. Developed by researchers at the University of British Columbia (UBC), the breakthrough technology uses excess carbon dioxide created in the fracking process to desalinate the process water, making it available for water reuse. It also generates chemicals — hydrochloric acid and carbonate salts — that are valuable for many industrial applications.
The long-term health of the Chesapeake Bay watershed, called by some “one of the world’s most fragile ecosystems,” has been well documented for decades. Excess runoff and discharges of nutrients have fueled the growth of algae blooms that impact water quality and aquatic life.
