One problem in effluent disposal is the limit set by public authorities on the permitted concentration of nitrate in public water supplies.

All biological treatment processes are dependent upon reproduction of the organisms employed. It cannot be assumed in waste management that all the major and trace elements needed in the stabilization of waste water will be contained in the waste being disposed of.

Bacteria are among the simplest forms of living matter and like all living matter they must reproduce in order to survive. Some bacteria live on simple sustrates, such as sugar, providing certain essential elements are present in the form of ions or inorganic salts.

It is known that the bacteria cell tissue contains about 12% nitrogen. To sustain life, bacteria must be able to synthesize protein from available sources of carbon and nitrogen. Most waste is deficient in nitrogen and this limits the extent to which bacteria can synthesize protein and thereby reproduce abundantly. Consequently BIEMS is formulated to provide adequate nitrogen. BIEMS contains many other substances required by bacteria, including biotins, amino acids, phosphorus, sulphur, inorganic salts etc.

Vitamins are also essential for maximum growth and activity such as Colene, Riboflavin and others within the B group. These are not always present in waste material and must be added as a supplement, especially as much of our food is grown on soils that constantly need replenishment of essential minerals and it cannot always be assumed that these elements will be available in sufficient amounts to sustain a high population of active digestive bacteria.

BIEMS provides both the trace elements and other compounds necessary to support bacterial reproduction and growth.

Most of the critical conditions exist during the summer months when dissolved oxygen deficiency is at its greatest because oxygen solubility is low due to higher water temperatures. This is a major factor in limiting the purification capacity of natural waters and it often necessitates treatment of wastes to remove pollution matter before it is discharged to the receiving streams.

In anaerobic biological treatment processes the limited availability of oxygen becomes a critical factor because it governs the rate at which oxygen will be absorbed by the medium. This often leads to excessive cost for artificial means of aeration.

BIEMS is a practical solution to the costly problems associated with BOD removal. As well as providing oxygen by natural means, it furnishes the most readily available sources of food for aerobic bacteria. The amount of BIEMS required can be varied to meet the requirements of any particular waste disposal system.
