Applications

Natural Water


To ensure the state of dynamic equilibrium of DO maintained by biochemical deplection by bacteria for the food chain and continued re oxy-generation by aeration and photosynthesis and thus the availability of right amount of DO which is vitally important for flora and fauna in water. To detect pollution - lower level of DO (normal 7.1 ppm) will adversely affect the aquatic life.

Agriculture
To ensure sufficient aeration in soil needed for underground respiration of plant roots in addition to photo synthesis.

Sewage Wastes

To ensure biochemical break-down treatment of sewage which is achieved by bacterial attack which requires DO. Non-availability of DO leads to increase activity of anaerobic, sulphate reducing bacteria resulting in production of hydrogen sulphide causing serious corrosion problem.

Foods & Drugs
To ensure oxidation is not adversely affecting the food stuffs. To ensure DO requirements for fermentation in foods, distilleries and Bio-synthetic preparations in Drugs & Chemicals.

Microbial Studies

To study effects of drugs on the brain tissues, other organs/limbs, circulation system muscle and connective tissues, malignant tissues and surface.

Boiler Feed Water

To ensure proper level of DO to avoid oxidative corrosion of Boiler pipes in steam generation, heaters etc.
