Dear Kunal,

Design Details for Sequencing batch reactor (SBR) for sewage treatment for Hindu Houses:

The plant is designed on the tried and tested Sequencing Batch Reactor (SBR) method, where 98 per cent of purification is achieved in just six hours, and without any chemical treatment. The waste water goes through a precise sequence of aeration, sedimentation and clear water removal, using gravity to separate waste particles of varying density. All three sequences happen in a single tank rather than three tanks. Aeration is the most important of the operations, and creates a suitable environment for natural bacteria to digest the waste in water. Two separate chambers are used — one is where the waste water is collected and the other is the SBR tank where the water is transferred for the actual biological process to happen. Here, short cycles of aeration and rest happen alternatively, resulting in the production of millions of micro-organisms that treat the water thoroughly. The recycled water in the house is used to raise the garden of fruit-bearing trees and other plants. For a family of up to six people, the size of the entire plant with both tanks is about 3,600 liters, which is much smaller than the septic tanks in many homes. For apartment blocks with up to six families (about 35 people), the size of the plant required is about 22,000 liters. The power consumed by the plant is about 8W per person, in other words, it’s roughly equal to a family using one 40W bulb. The price ranges from about Rs 1 lakh for a small plant that services a family of six to Rs 65 lakh for a plant used for 1,000 people. The technology is apparently one of the few that offers fully automated sewage treatment for single homes, apart from being suitable for apartment and commercial complexes, colleges, hospitals and resorts.

Thanks for the information , but am looking for the design basics for same. 

The design should contain a sludge treatment system in addition to the system described in Figure 5 depicted in our recent published paper (see attached file).

You can use the same system without RO membrane. This small plant is for recycling water received from bath rooms of our campus (AQ University).

Hoping this will be helpful,

Rafik Karaman has given excellent method for treatment of waste water from domestic unit. Only I can add the same technique can be used coupled with polyelectrolyte if you need better quality of water. for multipurpose use.
