Study of the efficiency of immobilized algal technology for wastewater treatment.

ABSTRACT

The present paper deals with the study of efficiency of immobilized algal technology in wastewater treatment. The acclimatized algal species and wastewater samples were collected from three different sampling sites such as Kham River, Waluj [MIDC], Salim Ali Lake for the study. The encapsulation of collected algal species such as Spirogyra, Cyanobacteria in mixture form and Arthospira from selected sampling sites were made in sodium alginate for wastewater treatment. The percentage efficiency of immobilized algal technology for wastewater treatment was studied with respect to physico-chemical parameters. The physicochemical parameters were analyzed before and after treatment and compared for percentage efficiency study. The results obtained from present investigation reveal that the immobilized algal technology has maximum percentage efficiency in reduction of BOD, COD, Total Hardness, Total Alkalinity, Chloride. TSS, TDS and TSS. Whereas, the minimum fluctuations were found in pH and temperature. However, the immobilized algal technology is also useful to increase the dissolved oxygen concentration in wastewater treatment process.
