Biological sewage treatment relies on microbial activity to break down organic pollutants, often involving processes like biodegradation and, in some systems, symbiotic relationships leading to photosynthetic oxygenation.
As per the safe drinking water guidelines issued by the Bureau of Indian Standards, Government of India, what is the acceptable pH value of drinking water? Ans: B pH is a measure of how acidic or basic water is. A pH of 7 is neutral. Values below 7 indicate acidity, and values above 7 indicate alkalinity. Maintaining pH within the acceptable range is important for water potability and preventing corrosion in pipes. 337. Sewage treatments generally involve _____. 1. Algal-bacterial symbiosis 2. Photosynthetic oxygenation 3. Biodegradation of organic matter 4. Ex-situ bioleaching
