STP projects are always challenging, but when upgrading of existing works is involved the challenge increases. The work consists primarily of duplication of primary plant, with further customisations if needed. The firms does extension work in three phases.

• Stage I : Duplication of primary digestor Plant and extension of power house.

• Stage II : Extension of sewage treatment plant

• Stage III : Construction of laboratory (optional) and administrative office.

The task to upgrade and expand the existing screening facilities, primary treatment, secondary treatment (bioreactors, secondary clarifiers, pumping stations), tertiary treatment (filtration phosphorous removal), service networks etc and the construction of new facilities.

Sludge treatment works and the construction of new facilities for the anaerobic digestion of the primary sludge, consisting of a digestion tank, a digested sludge storage tank, a digested sludge dewatering unit.

Much of wastewater produced today is contaminated with both soluble and insoluble impurities such as suspended solids, organics, pathogens, metals, nutrients and other priority pollutants that must be removed prior to discharge back into the environment.

They are categorized as follows:

• pH adjustment chemicals (to adjust pH level of treated water)

  alkaline chemicals: CaO (calcium oxide or lime), MgO (magnesium oxide), Ca (OH) (calcium hydroxide), Mg (OH) (magnesium hydroxide) acidic chemicals: Sulfuric acid (H2S04), Hydrochloric acid (HCl)

• Coagulant chemicals

  Ferric Chloride, Aluminium Chloride (AlCl3), Aluminium Sulphate [Al2(SO4)3] and Ferric Chloride (FeCl3).

• Flocculent chemicals

  Anionic polymers, Non-ionic polymers, Cationic polymers

Kelvin India, provides its clients with wide range of chemicals mentioned above and those needed for treatment of media filters used in STP, ETP and RO

     Media

It is in the last stage in the pre-treatment of water for removal of undissolved impurities prior to treatment by Ion Exchange or by Reverse Osmosis. Coagulation, flocculation and clarification precede filtration.

Kelvin provides both types of media filters, ie pressure and gravity filters. Kelvin provides best in class media with use of combined action of layers filters like: Activate carbon filter, dual media filter, multigrade filter, pressure sand filter, gravity filter and side stream filter. Coarse media filters are also supplied wrt the requirement. Kelvin provides the best solution for its clients according to their need.
