Sewage treatment is the process of removing contaminants from waste water and household sewage, both run of (Effluents) domestic, commercial and Institutional included physical, chemical, and biological process of removing physical, chemical and biological containment. The object is to produce on environmentally safe fluid waste stream or treated effluent and a solid waste (pr treated sludge) suitable for disposal or reuse, usually as Horticulture . Sewage Treatment Plants

We 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.

We are being pioneer in the field from last 10 years and always in the search of latest and techno-commercially viable technology, system by which the need of the society can be easily satisfied.

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

Technologies Used

• ASP : Activated Sludge Process
• MBBR : Moving Bed Bio reactor
• SAFF : Submerged aerated Fixed Film
• SBR : Sequential Bioreactor
• MBR : Membrane Bio Reactor.
  

Reverse osmosis (RO) is a membrane-technology filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution, when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective," this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely. Reverse osmosis is used to purify Water and remove salts and other impurities in order to improve the color, taste or properties of the fluid.

Water Softening Plants :
Water is considered ‘hard’ when it has excessive levels of calcium and magnesium dissolved in it. Hard Water can lead to the following Water problems :

• Scale build-up in pipes, resulting in decreased flow rates
• Scale build-up on heating and cooling systems, leading to increased electricity costs and breakdowns.
• White film on glass surfaces and staining on Water taps
• Increased laundry costs due to hard Water reacting with soap and laundry detergents.

The Water Softening Plants are designed to produce treated Water to suit for various applications. Treated Water is of consistency quality with low residual hardness throughout the service cycle. The high synthetic resin is used to exchange Sodium ion with hardness forming Calcium and Magnesium ions. After producing desired output, the resin is regenerated with (NaCI) Sodium Chloride solution after which unit is again ready to deliver next batch. The Water Softening Plant units are available with different models. The difference between these models is in the capacity of the resin used for each model. These units are easy to operate and maintenance free. These models are available to produce various capacities up to 200 Cu. Meters per hour maximum.

The Process.
Water softening methods mainly rely on the removal of Ca2+ and Mg2+ from a solution or the sequestration of these ions, i.e. binding them to a molecule that removes their ability to form scale or interfere with soaps. Removal is achieved by ion exchange and by precipitation methods. Mineral tank and the brine tank are the main constituents of the Water softening system. The Water softening system consists of a mineral tank and a brine tank. The mineral tank and the Water supply pipe is connected due to which Water passes through the tank before it can be used. Mineral tank consist of negatively charged beads or resins that attracts positively charged calcium and magnesium.

The surface of the resin gets coated with the calcium and magnesium minerals. The resin is cleared by flushing a strong sodium (salt) solution held in the brine tank. The sodium ions are powerful and they easily overpower the calcium and magnesium ions and drives them off of the resins which is later drained out of the unit.
