Turnkey Sewage Treatment Systems

TURNKEY SEWAGE TREATMENT SYSTEMS

SD Enviro Engineers Design, Fabricate, Supply, Erection and Commissioning Sewage Treatment Plants (STP) for treating sewage generated by Industry, large colonies, Hotels, Hospitals, IT Parks and commercial buildings.

Now a days the Sewage Treatment Plant (STP) became statutory requirement of all the State Pollution Control Boards, everybody, whether Hotelier or Industrialist were looking for economical, easy to install and operate compact type Sewage Treatment Plant.

Since the land is extremely expensive, very few industries could afford the large treatment units as recommended by most of the Consultants.

Sewage is generated by residential, institutional and industrial establishments. Sewage treatment is the process of removing contaminants from wastewater to use for reuse and or for safe disposal.

Sewage treatment generally involves three stages called primary, secondary and tertiary treatment. Primary treatment consists of temporarily holding the sewage, separation of oil, grease, floating matter and grit etc. Secondary treatment removes suspended and dissolved biological matter. It also includes separation of micro-organisms from the treated water prior to tertiary treatment.Tertiary treatment involves fine filtration and disinfection for final reuse or discharge.

Biological treatment comprises an aeration tank with external air supply. Surface aeration and diffused aeration are used to provide required oxygen. Suspended growth systems where biomass is mixed in sewage and recycled back to aeration. Fixed film or attached growth systems use media where biomass grows and sewage passes over its surface. Attached growth system requires lesser foot print than suspended growth system and able to cope with varying loads of influent.

Recycling and reuse of maximum sewage on site will help in reducing the fresh water use for various non potable uses like landscaping, WC flushing, external cleaning, vehicle washing,construction and for utilities like cooling towers.

Principle of Treatment :

Its working on the principle of Aerobic Treatment with the help of aerobic bacteria, which is most conventional and proven method throughout the world. Envicare’s Modified Septic Tank (MST) Systems – Its works on principle on anaerobic digestion.
