Determination of Water Pollution of River Ganga during Lockdown Period | Chapter 3 | New Visions in Biological Science Vol. 5

 In this study, the water quality of the Ganga River was investigated, as well as the effect of lockdown on the physicochemical parameters of the river water in Bihar. The study's goal was to check the Ganges' water quality during the lockdown and assess the impact of the situation on the river's water quality, with a focus on a few areas in Bihar where domestic sewage, agricultural wastes, and air pollution affecting river water are thought to be the major sources of pollution. Both primary and secondary data were collected as part of the exploratory study strategy. In the months of March and April, primary data was obtained from the Ganges sampling stations of Digha (Patna), Arrah (Bhojpur), and Aami (Saran). pH, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Total Coliform (TC), and Faecal Coliform (FC) were all tested after the data was collected (FC). During the lockdown, the river's quality did not much improve. It is clear that, in comparison to non-industrial areas, industrial areas have seen a reduction in water pollution along the Ganga. Domestic garbage dumping did not stop and even increased in hygiene maintenance in non-industrial regions, therefore there was little improvement.

Aerobic Brickbat Grit Sand (ABGS) Purifier: The New Technology for Treatment of Wastewater in Rural India | Chapter 12 | New Approaches in Engineering Research Vol. 7

 In emerging and underdeveloped countries, rural wastewater treatment is largely disregarded. The most significant impediment to resolving this issue is the high expense of treatment and the lack of readily available technologies. There are four phases to the Aerobic Brickbat Grit Sand (ABGS) purifier. Wastewater travels in a zigzag pattern via partition walls with brick bats filters, pebble sand filters, and charcoal and grit filters to help remove impurities from domestic wastewater. An experimental model for home wastewater treatment was put up in the Environmental Engineering lab at Government College of Engineering Aurangabad, Maharashtra, for the current study. Analytical physiochemistry The percentage removal of pollutants data include Biological Oxygen Demand (BOD) 92-87 percent, Chemical Oxygen Demand (COD) 93-89 percent, Total Suspended Solids (TSS) 80-78 percent, and Turbidity 95-85 percent in August and September of 2016. Following the successful testing of the experiment model, a pilot model for the treatment of boys hostel grey water was established on the same site. The ABGS purifier pilot plant model for grey water treatment has a high efficiency in removing BOD (89%), COD (90%), TSS (86%), Total Phosphorus (77%), Nitrate (93%), and Ammonia (93%). (90 percent ), 67 percent sulphate, oil and grease (82 percent ). The ABGS purifer is an eco-friendly and simple-to-install household wastewater treatment system that uses locally accessible materials. The ABGS purifier is a decentralised technique of treating domestic wastewater. As a result, ABGS has emerged as an alternative solution to the problem of rural wastewater treatment.
