SEWAGE TREATMENT PLANT

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.

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.

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.
