Treatment and reuse of domestic sewage by MBBR technology (India)

Treatment of domestic sewage and its recycling is an important environmental issue. Not only for the prevention of pollution, but also as a measure of water conservation. It is becoming more of a norm and requirement as days pass. Many processes have evolved over the time, the main consideration being space, costs, and ease of operation and maintenance. Every requirement has its own appropriate technology. One of the popular processes is the moving bed bioreactor (MBBR) in urban areas where space is a constraint. This thesis covers a broad subject of the historical data on generation and treatment of domestic sewage, various treatment processes available, and reasons why a particular system of MBBR is chosen. Thereafter, as a case study a typical plant of 135 KLD has been chosen for working out the detail designs, specifications, operations and cost estimates. Also, relevant drawings and photographs have been included for better visualization and understanding.
