UTILIZING NOSTOCLINKIAALGA IN REDUCING CONCENTRATIONS OF DYES PRODUCED FROM TEXTILE INDUSTRIES AND DRAINING TO THE AQUATIC ENVIRONMENT

Abstract

ABSTRACTOne genus of algae Nostoclinkiaas dried and livingwas used in reducingtheconcentration of direct blue and reactive red dyes and color in textile factories. Theproper concentration 1 gm/L was prepared for each dye, however 0.005. 0.01, 0.03g/Lwere prepared from this concentration and used for 4 days of treatment. The resultsconfirmed that the efficiency of 1g from dried alga in reducing concentrations of dyesincreased during period of treatment which recorded removal percent for direct blueat 0.005. 0.01, 0.03g/L concentrations as 83.11%, 73.05%, 63.6% after 4 days oftreatment,while the removal percent for the same dye with 0.5 g of algawas57.44%,71.57% ،56.23% respectively. Living filamentous alga was recordedhigher removal percent for reactive red at 0.005, 0.01, 0.03g/L concentration after 96hrfrom treatment 72.88%, 61.63%, 34.75% respectively. The results illustrateincreasing in algal biomass with increasing period of treatment and algal biomass intreatment, algal biomass of 1 g after 96 hr from treatment with direct blue dye wererecorded 2.682,2.564,2.33g while algal biomass at 0.5 g after the same period oftreatment 1.531, 1.395, 1.274grespectively. Also, the living alga recorded increasing inbiomass 47.73, 43.73, 34.97mg after 96hr from treatment with reactive red
