Testing the efficiency of Scenedesmus quadricauda alga to reduce industrial pollutants in the water.

Abstract

This study aims to use alga Scenedesmus quadricaud in reducing the rates of phosphate and nitrates from waste water industry as environmental pollutants cause a risk to the aquatic environment before throwing it into the water .The results showed that the alga Scenedesmus quadricauda candidate biological effective in reducing the concentrations of phosphate - phosphorus and nitrate - nitrogen from industrial waste water .The highest average of removing for phosphate 100,100,97.8,91.6 for concentration 2,5.10,20mg/l respectively and the highest average of removing for nitrate 99.3,99.4.99.9,100%for the same concentrations respectively.
