Sewage Treatment refers to the process of removing contaminants, microorganisms and other types of pollutants from wastewater.

Wastewater, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial waste.  It is treated in a multi-stage process by the Water Companies that make it safe to return to the environment.

The wastewater undergoes several stages in its municipal treatment process for Environmental Protection:

This involves the screening and removal of large debris, including sanitary towels, tampons, sticks, leaves, rags, wet-wipes, etc. from the raw sewage as these are not readily biodegradable by the process bacteria.  They are then dried and sent to landfill sites or incinerated.

It also involves the removal of sand and grit which is settled out in tanks and also removed to landfill sites.

This is another settlement stage, during which mainly organic solids sink to the bottom and form a sludge and fats rise to the surface and form a scum or crust.  This crust is colonized by aerobic bacteria (they breathe oxygen) and partially digested. The liquid between these two layers drains off for processing in the Secondary treatment stage and the sludge and crust are removed periodically for further treatment.

This stage involves the introduction of oxygen to the sewage and uses aerobic bacteria to break down the organic matter, coming mainly from human body waste, in the liquid part of the sewage.  They also reduce the amounts of other contaminants, detergents, etc. and the quality of the resulting effluent is usually regarded as safe for discharge to a watercourse, unless the watercourse is sensitive or already polluted.  The dead bacteria and humus are allowed to settle out in a clarifying chamber and this sludge is also removed periodically for further treatment.

Tertiary Treatment

This stage is required for sensitive discharge points eg. trout streams.  Tertiary treatment involves a further aerobic stage, followed by an oxygen depleted stage, which reduces nitrogen and phosphorus. It can also include a disinfection process using UV light, chlorination or ozone treatment to remove bacteria and viruses.

provides the best solution to treat sewage water through sewage treatment plants based on anaerobic and aerobic process and designed to have a dual functions for efficient treatment of domestic wastewater from toilets , bathrooms , kitchen and washing area.

In all over the world it has been recognized that decentralized wastewater treatment is a better alternative to a centralized wastewater treatment system from the angle of investment, energy consumptions and efficiency. There are so many areas within cities, towns and villages that are impossible to cover through centralized treatment systems. It has therefore become imperative to evolve decentralized treatment systems that take care of proper treatment and disposal of sewage.

Industrial effluent is any wastewater that is produced by various industrial activities. The quality of industrial effluent/wastewater varies from one industry to another is responsible for the degradation of receiving water sources. In other words, treating all kinds of effluents originating from various industries using an industrial ETP/Effluent Treatment Plant is extremely desirable.

Industrial effluent treatment is the effective process of treating wastewater that is highly contaminated by industrial wastes, making it fit for reuse or disposal/discharge back to the natural environment.

Sewage contains a huge amount of organic matter which is toxic. Microorganisms are widely used in the sewage treatment plant for removing this toxic organic matter. Sewage or wastewater treatment plant consists of two stages.

• Primary Treatment

It involves the removal of large or small-sized components in the wastewater through physical processes.

• Biological Treatment:

Aerobic microorganisms are inoculated into the sewage treatment plant. These microbes utilize the organic components of the sewage and reduce the toxicity. This can be measured by BOD (Biological oxygen demand).

After the biological treatment, the sludge is pumped from the treatment plant into a large tank. This large tank consists of anaerobic bacteria which lead to the digestion of sludge. During digestion, biogas is produced and it is used as an energy source. Hence, Sewage treatment plant design and sewage management play a crucial role in the maintenance of human welfare.

A natural process of decomposition of the organic matter by living microorganisms (bacteria, algae, protozoa) with light and dissolved oxygen is set up. Treatment of sewage or wastewater protects public health and prevents pollution, disease as well as hazards from sewage contaminants. Sewage treatment plant is to analyse and characterize the components of the sewage, select a series of technologies to remove or neutralize each those components you wish to change, and size the system to address the volume, concentration and temperature range expected.

MBBR is a biofilm process. This technology is essentially the same as Activated Sludge Process (ASP) except that the media suspended in the reactor offers additional surfaces for the microbes to grow and this in turn maximizes the growth of microbes in a given volume of aeration tank compared to the conventional aeration without the media and to that extent, it does appear preferable. MBBR system is often installed as a retrofit of existing activated sludge tanks to increase the capacity of existing system. Diffused aeration is also required. FAB technology is akin to MBBR except that instead of the media in suspension, the media is kept stationary and fluidized in the aeration tank.
