Click here for our range of sewage treatment plants. It includes physical, biological and sometimes chemical processes to remove pollutants. Reuse is often for agricultural purposes, but more recently, sludge is being used as a fuel source. Organic wastes, suspended solids, bacteria, nitrates, and phosphates are pollutants that must be removed. It is called 'Decentralisation' of sewage treatment systems.

They also may, after sterilisation, be used for certain types of irrigation such as golf courses , transported to lagoons where they are evaporated, or discharged through underground outfalls into the sea.

However, sewage water outflows from treatment works must meet effluent standards set by the Environment Agency to avoid polluting the waters that receive them.

The effluent produced by this process is highly polluting and cannot be discharged to any watercourse. It must be discharged into the Aerobic layer of the soil within the top metre of the ground for the aerobic soil bacteria to continue the sewage treatment via the aerobic process below. Aerobic Sewage Treatment In this process, aerobic bacteria digest the pollutants. Aerobic conditions lead to an aerobic bacterial colony being established. The effluent produced by this process is non-polluting and can be discharged to a watercourse Conventional sewage water treatment involves either two or three stages, called primary, secondary and tertiary treatment.

Before these treatments, preliminary removal of rags, cloths, sanitary items, etc. Primary Treatment This is usually Anerobic. They settle out at the base of a primary settlement tank.

The sludge is continuously being reduced in volume by the anerobic process, resulting in a vastly reduced total mass when compared to the original volume entering the system. Secondary Treatment This is Aerobic. The liquid from the Primary treatment contains dissolved and particulate biological matter. This is progressively converted into clean water by using indigenous, water-borne aerobic micro-organisms and bacteria which digest the pollutants.


In most cases, this effluent is clean enough for discharge directly to rivers. Sarah Hubbell Julian Sandino, P. Thomas E. Jenkins, P. Paul J. Schuler, P. Samuel S. Jeyanayagam, Ph.

Spalding, P. Krause, P. The primary function of the Committee is to originate and produce, through appropriate subcommittees, special publications dealing with technical aspects of the broad interests of the Federation.

These publications are intended to provide background information through a review of technical practices and detailed procedures that research and experience have shown to be functional and practical. Passaro, P. Fernandez, Past Chair J. Bannen P. Bizier, P. Conway, P. Copithorn S.

It facilitates access to those design guides by providing concise information from them and enabling the reader to quickly locate addi- tional information by following direct references. This reference is written for students and design professionals familiar with wastewater treatment concepts, the design process, plant operations, and the regulatory basis of water pollution control.

It is not intended to be a primer for either the inexperienced or the generalist but still a tool for them as well, allow- ing them to quickly identify where they can find more information for unfamil- iar subjects.
