Water Treatment

WATER TREATMENT

Drinking water

Indian ground waters contain large amounts of organic load, which is the best nutrient
for bacteria. Therefore, however pure the source of water may be, only ozonation can kill bacteria, virus, cysts, algae, fungi and oxidize nitrogenous matter in the water making it sparkling clean. Most raw water sources contain naturally occurring organic compounds with which halogens such as chlorine combine to form carcinogenic haloforms.

Several hotels, clubs, resorts and leading mineral water brands all over India use Ozone systems. Drinking ozonated water ensures protection from all water borne diseases including jaundice.

0.1 ppm active Chlorine needs 4 hrs to kill 6 x 104 E. Coli cells whereas the same concentration of Ozone kills the same quantity of bacteria in 0.5 seconds.

Industrial Process Water

Industries which require very pure demineralized water (often with the additional need for sterilization) face fouling of anion resins by organic acids, iron and manganese a serious problem.
The best solution is to utilize the disinfection, coagulating and oxidizing properties of Ozone. When applied before filtration and demineralization, Ozone removes iron and manganese and breaks down organic compounds.

High Purity Water

High purity water is typically encountered in the pharmaceutical and semi-conductor industries. In order to maintain water integrity with low CFU counts and TOC levels it has become standard practice to add a small amount of Ozone.

Otsil also provides Wels Technology from WEDECO for generation of Ozone by Electrolysis for the pharma Industry.

Poultry Chill Water

Treatment of recycled poultry chill water with Ozone achieved reductions in excess of 99% for total aerobes, E Coli and coliforms.


Ultrapure Water

Ultra-pure water is normally associated with the semi-conductor industry. Here the purity specifications are so high that every conceivable measure is taken to avoid all ionic and microbial contamination.


Deionized Water

Normal disinfectant methods cannot be used to treat deionised water in the pharmaceutical, semi-conductor and personal-products industries. A very effective method of achieving low CFU counts is to sanitize with Ozone.


USP Validated Water

USP validated water is mainly encountered in the pharmaceutical industry where it is used for the sanitation of process water used in the manufacture of parenterals.
