Working Procedure Of Effluent Treatment Plant (ETP)

Sewage Treatment refers to the process of removing contaminants, micro-organisms and other types of pollutants from wastewater. Water that drains from industries, farms, hospitals, commercial sites, houses (washing machines, dishwashers, sinks, showers and toilets) is waste water or raw sewage. Through a multi-stage process, the waste water is treated by the Water Companies which make the water safe to return to the environment. All the contaminants are removed from the household sewage water and wastewater. The water is treated to use it again for agricultural purposes. Pollutants that are removed include phosphates, nitrates, bacteria organic wastes and suspended solids. The concentration of these pollutants and contaminants is reduced to a safe level set by Environment Agency, so that it can be reused or returned to the environment.

Many methods like chemical, biological and physical are applied for the treatment of sludge. Sludge is contaminated with toxic organic and inorganic compounds and diseases. The treatment process must eliminate all contaminants and make it suitable for discharge or reuse back into the environment. There are many pathogens which can not be destroyed by the treatment process.

Protection:

Pre-Treatment
This step includes screening and removal of large, non biodegradable debris from the sewage. The removed debris is dried and sent to landfill sites or incinerated. The sand and grit settled out in tanks are also removed to landfill sites.

Primary Sewage Treatment
In this settlement stage, organic solids sink to the bottom in the form of sludge. While, the fats rise to the surface and form a crust or scum. The rest liquid in the bottom of surface crust layer and bottom sludge layer is drained for processing in the Secondary treatment stage. The crust and sludge are removed periodically for further treatment.

Secondary Sewage Treatment
In this stage, oxygen is introduced to the sewage. The aerobic bacteria is also used for breaking down the organic matter, especially human body waste in the liquid part of the sewage. The other contaminants and detergents are also reduced. The resultant effluent is considered safe for discharge to a watercourse, unless the watercourse is already polluted or sensitive. In a course of time, the humus and dead bacteria settles out in a clarifying chamber. The sludge is timely removed for further treatment. Environment Agency accepts only those sewage treatment plants that have an EN 12566-3 2005 certificate.

Tertiary Treatment
Tertiary treatment involves an aerobic stage, and then an oxygen depleted stage. It reduces both phosphorous and nitrogen. This treatment also include a disinfection process which uses UV light, chlorination or ozone treatment for the removal of viruses and bacteria.

Features of wastewater treatment systems are determined by:

The nature of the industrial and municipal wastes conveyed by the sewers.

The amount of treatment needed for keeping the quality of the receiving rivers and streams.

The treated wastewater is usually discharged from treatment plants to rivers or lakes. The treated water may also be after sterilisation used for irrigation of certain types. The water discharged in rivers must meet effluent standards set by the Environment Agency, so as to avoid polluting the waters that receive them.

Two basic types of Sewage treatment plant processes:

Anaerobic Sewage Treatment
Anaerobic bacteria in a tank filled with sewage partly decomposes the sewage, without introducing air, containing oxygen. This process reduces the organic matter into carbon dioxide, methane, hydrogen suphide, etc. It is used for the treatment of wastewater sludge and organic waste. This processes reduces the input material in large volume. The methane is being examined for use in households and industries for the purpose of heating. An example of anerobic process is septic tanks. The effluent treated in septic tank still contains about 70% of the original pollutants. If the hydrogen suphide is not vented correctly, this process smells very badly. The effluent is not suitable for discharge as it stills contains pollutants. It must be discharged into the soil's Aerobic layer of the soil. The aerobic soil bacteria continues the sewage treatment via the aerobic process.

Aerobic Sewage Treatment

Aerobic bacteria digests the pollutants in this process. Air must be provided to allow bacteria to breathe. It can be done either by direct aeration or submerged diffused aeration, to the Biozone. By creating aerobic conditions, aerobic bacterial colony can be established. The organic matter and pollutants are oxidized and digested to Carbon Dioxide, Nitrogen and Water. It eliminates the odour and pollution problem. The resultant effluent is non-polluting and can be discharged to a watercourse.

Traditional sewage water treatment involves either two or three stages, naming primary, secondary and tertiary treatment. Before these treatments, all large, non biodegradable debris is removed at municipal sewage works.

Get sewage treatment plant installed
By installing this plant, the sludge can be timely eliminated by tanker and further processed via anerobic/ aerobic process. It is then disposed of or re-used. The treated water can be discharged into a river, stream, lagoon or wetland. It can also be used for the irrigation of a park, golf course or green way. If the water is sufficiently clean, it can also be used for agricultural or groundwater recharge purposes.
