Sewage Treatment Plant

Product Details:

What is Sewage?
Sewage is a mixture of domestic and industrial wastes containing 99% water, but the remainder contains some ions, suspended solids, toxic chemicals and harmful bacteria that must be removed before releasing of water into the sea.

Sewage contains organic impurities such as BOD, COD which cause bad smell and contains harmful gases. If it is not treated properly then it will lead to many irreversible problems for human & other living things.

Why Sewage treatment is necessary?
Sewage is a resource that can be recycled for various uses like gardening, toilet flushing, car wash, cooling towers. Faced with the alarming fact that over 60% of the sewage generated in our country goes untreated, with its negative impact on human health, the government is focusing on waste management through centralized sewage treatment plants and by mandating large upcoming real estate projects to have their own treatment facility.

Sewage Treatment is essential to ensure that the receiving water into which the effluent is ultimately discharged is not significantly polluted. It works on producing environmentally safe fluid waste stream and a solid waste suitable for disposal or reuse.

Excel Filtration Pvt. Ltd (EFPL)’s approach is to see wastewater as an opportunity, not a burden.

1. Preliminary Treatment

The influent sewage water passes through a bar screen to remove all the large objects like cans, rags, sticks, plastic packets etc. which are carried in the sewage stream.

2. Secondary Treatment

a. Anaerobic Zone-

The first stage of PSTP is an oxygen-depleted anaerobic zone in which the solids in raw sewage get settled while allowing the scum to float on the surface. It is a zone in which the settled sludge is stabilized by anaerobic digestion.

b. Anoxic Zone-

The sewage then enters the anoxic zone in which denitrification of the wastewater stream is accomplished by returning the activated sludge from the final sedimentation zone to the anoxic zone; wherein dissolved oxygen levels are maintained approximately as 0.2 to 0.5 mg/l. In the denitrification process, anoxic microbes break down to the existing nitrates, this results in the release of inert nitrogen gas into the atmosphere.

c. Aeration Zone-

The sewage from the solid separation zone flows into the aeration zone. Air is diffused with the help of air blowers which encourages the growth of bacteria cultures in and around the floating plastic media added in the aeration zone. The MBBR media provides the extended surface area for the growth of microorganisms.

d. Sedimentation Zone-

The next step of treatment involves the sedimentation zone where organic waste is settled. The settled waste in the bottom of the tank is pumped back to the anoxic zone as a return sludge, which is done to ensure that the quality of effluent must pass the stipulated sewage parameters.

3. Tertiary Treatment System:

The secondary treated sewage is then passed through the Pressure Sand Filter and Activated Carbon Filter for the removal of suspended solids (TSS), color, and odor. The treated water is then disinfected using sodium hypochlorite before it is reused.

We supply various types of sewage treatment plants in India such as household sewage treatment plant , domestic sewage treatment system , commercial sewage treatment plant , SBR sewage treatment plant , Residential sewage treatment plant , MBBR sewage treatment plant , Industrial sewage treatment plant , mbr sewage treatment plant.

It involves the process of removing contaminants from wastewater and household sewage, both effluents and domestic. It includes physical, chemical and biological process to remove physical, chemical and biological contaminants. The objective of sewage treatment is to produce a disposable effluent without causing harm to the surrounding environment and prevent pollution.

Sewage treatment generally is divided into several stages:

Pretreatment :

Large solids (i.e. those with a diameter of more than 2cm) and grit (heavy solids) are removed by screening. These are disposed of in landfills.

Primary Treatment :

Primary treatment removes materials that can be easily collected from the raw sewage before they damage or clog the pumps and sewage limits of primary treatment clarifiers trash, tree, limbs, leaves, branches etc. Here settled and floating materials are scrapped off and the remaining liquid discharged and subjected to secondary effluent.

Secondary or Biological Treatment :

 Secondary treatment removes dissolved and suspended biological matter. It is typically perform by indigenous, water-borne micro-organisms in a managed habitat. It requires separation process to remove microorganisms from the treated water before its discharge or tertiary treatment.

Tertiary Treatment :

Tertiary treatment is to provide a final treatment stage to raise the effluent quality before it is discharged to the receiving environment (sea, river, lake, ground etc). This is a final process and also called “effluent polishing.
