This paper considers study of lab-based model treating greywater. The model combines electrocoagulation and filtration technologies for greywater treatment and its optimization so as to alleviate water scarcity. Greywater is a non-potable water that can be re-cycled and re-used. The research work explores utilization of hybrid electrocoagulation and filtration technologies. It conducts and optimizes impact tests on anode and cathode in continuous manner. For this purpose, combinations of aluminium (Al) and copper (Cu) are considered. The electrodes are arranged in 2 sequences. These are Al:Cu:Al:Cu and Cu:Al:Cu:Al. The study discovered that when cathode and anode were separated at 20 mm distance for Al:Cu:Al:Cu arrangement, 94.20% of COD was found to be removed. The specific energy was observed to be 1.95 kWh/m3 and the operating cost was optimized to 18.50 INR. In addition, Al:Cu:Al:Cu consumes less energy than that of Cu:Al:Cu:Al, resulting in higher current efficiency. The study also shows that the hybrid electrode has high removal efficiency while running at a lower voltage for both Al:Cu:Al:Cu and Cu:Al:Cu:Al indicating the effectiveness of model for greywater treatment obtained from multi storied buildings.

摘要

This paper considers study of lab-based model treating greywater. The model combines electrocoagulation and filtration technologies for greywater treatment and its optimization so as to alleviate water scarcity. Greywater is a non-potable water that can be re-cycled and re-used. The research work explores utilization of hybrid electrocoagulation and filtration technologies. It conducts and optimizes impact tests on anode and cathode in continuous manner. For this purpose, combinations of aluminium (Al) and copper (Cu) are considered. The electrodes are arranged in 2 sequences. These are Al:Cu:Al:Cu and Cu:Al:Cu:Al. The study discovered that when cathode and anode were separated at 20 mm distance for Al:Cu:Al:Cu arrangement, 94.20% of COD was found to be removed. The specific energy was observed to be 1.95 kWh/m3 and the operating cost was optimized to 18.50 INR. In addition, Al:Cu:Al:Cu consumes less energy than that of Cu:Al:Cu:Al, resulting in higher current efficiency. The study also shows that the hybrid electrode has high removal efficiency while running at a lower voltage for both Al:Cu:Al:Cu and Cu:Al:Cu:Al indicating the effectiveness of model for greywater treatment obtained from multi storied buildings.
