Reverse Osmosis Treatment for Nitrate Removals in High Solids Wastewater

A wide range of industrial wastewaters have, in addition to specific hazardous substances in lower concentrations, high levels of other solids which increase the difficulty of treatment. Our group has been looking at these high solids wastewaters as candidates for R 0 treatment. Newer membranes operated at lower pressures with better washing procedures make the R 0 process more attractive for hazardous waste, leachates and other high solids wastewaters. High solids chrome bearing wastewater has been processed full scale, high solids wastewater with high levels of ammonia are under study and this particular work involves high solids wastewater with nitrates the ion of interest for removal.
