The Activated Sludge Process for the Sewage treatment which is well known and widely used was first invented by Edward Ardern and William Lockett in 1914.
Sewage is a waste water from houses and other institutions, industries while septic tank is a treatment unit for sewage from small communities
No. Water Treatment is treatment of river water, surface, ground water etc for drinking purposes whereas sewage treatment is treatment of sewage i.e wastewater such as from Kitchens, toilets etc Linesh Chungath
There are basically two types of sewage treatment plants 1. Chemically treated - where chemicals are added to break down the effluents and disinfect it 2. Biologically treated - the effluent is broken down with the help of aerobic bacteria
That depends on how your sewage is treated, it could go into a septic tank in your garden or it could go into the public sewer and on to a sewage treatment works (sewage farm). In both cases raw sewage is prevented from discharge directly into the environment and the sewage is retained until natural processes have converted it into water that is safe to discharge.
Primary treatment
The bacterial bugs eat the dirty things from the water
Primary sewage treatment involves physical processes that remove large particles and debris from sewage water. This can include processes such as screening to filter out large objects, sedimentation to settle out suspended solids, and skimming to remove floating materials. While primary treatment is effective in removing some contaminants, it is not sufficient for fully treating sewage water to meet environmental discharge standards.
Primary sewage treatment typically involves the use of a grit chamber, primary sedimentation tank, or clarifier. These machines are designed to remove large solids and settleable organic matter from wastewater through processes like sedimentation and flotation. The primary treatment focuses on reducing the suspended solids and organic load before the water undergoes secondary treatment.
The three stages of sewage treatment are primary, secondary, and tertiary treatment. Primary treatment involves physical processes to remove large solids and debris. Secondary treatment uses biological processes to break down organic matter. Tertiary treatment involves advanced processes to remove any remaining contaminants before the treated water is released back into the environment.
Sewage treatment plants use microorganisms to destroy the biological material in sewage.

Primary sewage treatment essentially removes the lumps from raw sewage by settling and some of the organics by holding the waste before discharge. Secondary treatment de-lumps and then removes organics by allowing bacteria to feed on the nutrients then removing/collecting the bacteria for disposal. Tertiary treatment filters or chlorinates the treated waste to remove smaller particulates and bacteria.

Sewage treatment is an essential process in a more advanced society. Untreated sewage can reenter the water system and spread disease. Land around a sewage treatment plant would be cheap, as it is a less desirable area to live, because of the bad smell.
