ABSTRACT
Microbial based treatments are more economical, ecofriendly and sustainable alternative for waste treatment to existing chemical or physical treatment methods. The metabolic rate of microorganisms effect pH, BOD, COD, DO, concentration of suspended solids present in waste waters. Phototrophic consortium from sewage water was used in the present study to remediate sewage water. Treatment with bacteria caused a significant decrease in some of the parameters tested for waste water. Remediation of sewage water of Panagal by photosynthetic bacteria showed a 23% decrease in DO and 64% decrease in BOD was observed which was significant. COD and organic matter decreased to the extent of 32% and 75% respectively. Chloride levels (6%), bicarbonates (32%) and sulphates (19%) were also decreased. Remediation of sewage water of Prakasam bazaar by photosynthetic bacteria showed a decrease in DO by 22%. Chemical oxygen demand and Biological oxygen demand decreases were significant and were to the extent of 60% and 38% respectively. Bicarbonates (45%), chlorides (35%), sulphates (16%) and organic matter (28%) also decreased significantly.
