Environmental Engineering Laboratory

Environmental Engineering Laboratory, being established during 2012 is fully equipped with relevant equipment and sensors for monitoring water and wastewater qualities including concentration levels of total dissolved/suspended solids, turbidity, hardness, alkalinity, acidity, chlorides, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, ammonia, nitrate, phosphate, and most probable numbers of bacteria. At present, this laboratory is maintained and operated to conduct experiments at UG and PG level course curriculum. The research equipment with more advanced features is under process to get installed in this laboratory.

(i) Project title: Simultaneous removal of carbon, nitrogen, and phosphorus from landfill leachate using an aerobic granular reactor

Summary of project:

Landfill leachate majorly consists of carbon, nitrogen, phosphate, metals, and other micropollutants, which causes a severe threat to the environment. In this project, an aerobic granular reactor (AGR) has been developed to treat landfill leachate collected from a landfill site. The AGR successfully removed carbon, nitrogen, and phosphorus simultaneously at higher organic loading. The co-treatment of leachate and wastewater has also been investigated using AGR to determine its stability.

(ii) Project title: Treatment of domestic sewage and leachate using a moving bed hybrid bioreactor

Summary of project:

The treatment of domestic sewage using a moving bed hybrid bioreactor (MBHBR) has been investigated by varying the concentrations of chemical oxygen demand (COD), ammonia, phosphorus, and hydraulic retention times (HRTs). The stability of MBHBR has also been studied to understand its performance in shut-down and shock loading phases. The MBHBR has shown higher removal efficiencies for COD, ammonia, and phosphorus during the co-treatment of sewage and leachate. The metagenomics study has been performed to identify the predominant microorganism in MBHBR, which played a significant role in the treatment of sewage and leachate.
