Sewage - Wikipedia
Sewage - Wikipedia

Sewage, or ,domestic,/municipal ,wastewater,, is a type of ,wastewater, that is produced by a community of people. It is characterized by volume or rate of flow, physical condition, chemical and toxic constituents, and its bacteriologic status (which organisms it contains and in what quantities). It consists mostly of greywater (from sinks, bathtubs, showers, dishwashers, and clothes washers ...

The test for pH value of ,wastewater, is carried out to determine whether it- is ,acidic, or alkaline in nature. Fresh sewage is generally alkaline in nature, (its pH value between 7.3 to 7.5). However, as the time passes, pH value tends to fall due to production of acids by bacterial action, and the sewage tends to become ,acidic,.
