Dissolved Oxygen Analyser
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.
- 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.
- MICROBIAL STUDIES
To study effects of drugs on the brain tissues, other organs/limbs, circulation system muscle and connective tissues, malignant tissues and surface.
- AGRICULTURE
To ensure sufficient aeration in soil needed for underground respiration of plant roots in addition to photo synthesis.
- 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.
- BOILER FEED WATER
To ensure proper level of DO to avoid oxidative corrosion of Boiler pipes in steam generation, heaters etc.
