Some farmers and food processors, who produce a lot of animal and organic waste, dispose of this waste in ‘anaerobic’ waste ponds (anaerobic means that the ponds are not oxygenated). This is due to a lack of available power and the fact that there are no neighbours for miles to smell the odour. These ponds usually crust up on the surface and are only 70% efficient in processing waste.

Due to urban sprawl, increased output and the use of caustic cleaning chemicals, these and other unsophisticated pond systems cannot cope, and industries are under pressure to improve odour control. Aerobic ponds (oxygenated), if correctly designed, are up to 95% efficient and will provide the solution if they have aeration and beneficial bacteria suitable for the waste.

Industry improved early pond systems by introducing aeration methods such as the commonly found surface paddlewheel. This type of aeration is expensive, consumes high energy and has inherent maintenance problems.
Industry also developed methods of increasing bacterial colonies in their ponds such as by throwing in a dead animal, as well as the more scientific method of culturing their own bacteria. Culturing bacteria is very time consuming, expensive and not always efficient in quality and quantity of bacteria produced. The biggest concern with culturing bacteria is that the product cannot be stored unless freeze dried (expensive and with mixed results).

ETG has developed the science to keep high quality specific beneficial bacteria dormant in liquid suspension. To our knowledge we are the only company in the world using this procedure. This has solved the problem for industry in having a high quality inexpensive, beneficial bacteria supply which can be stored and used when needed.
