Biochemical Oxygen Demand (BOD) is the amount of oxygen required to bring about complete biochemical oxidation of organic matter. The term “decomposable” means that the organic material is utilised by bacteria as a source of food and energy.

The BOD test is the usual parameter to measure the organic pollution of domestic and industrial wastes. It provides a useful measure of the amount of oxygen which will be required if an effluent which is not fully oxidised is discharged into a watercourse where aerobic conditions exist. The BOD test therefore provides a measure of the degree of pollution in a water course which will result from addition of the effluent .

Under natural conditions organic matter is degraded by a wide range of organisms which promote oxidation of carbon to carbon dioxide, nitrogen to nitrate ion, sulphur to sulphate ion, phosphorus to phosphate ion, and so on. Hydrogen is converted to water. Inorganic materials, trace elements, etc either remain in solution (usually as the chloride) or are precipitated as a sediment, depending upon the pH of the solution.

The predominant organisms responsible for these processes are naturally present in the soil and most waterways.

Benefits of BIEMS

• 80% reduction in final effluent after applying BIEMS
• Increase capactiy of plant. In tests as high as 20%. Which marks a huge capital/cost saving
• Fast acting, within 24 hours see activity but momentum maintains for 21 – 28 days
