Today, due to rapid industrialization, global warming and the environment have become the cause of great concern and the real-live issue of the world. The industries are being pursued rigorously to ensure that the pollution control and energy conservation systems adopted are continuously under operation. Hence the adoption of suitable economically cost-effective energy conserving and very efficient methods of pollution control is the top priority for any Industry.

Under the pursuit of quality assurance, Environ has conducted and given in-house oxygen transfer tests as per American Standard and Wrinkler’s procedure for:

In any effluent treatment plant, having chemical and biological treatment, most of the energy is consumed in biological secondary treatment. Hence the energy reduction of secondary biological treatment becomes the topmost priority aspect for us. Hence the energy-efficient aerators suitable for primary & secondary effluent treatment, become the most important criteria nowadays, so far as reduction in energy consumption and global warming are concerned.

Continuous R & D activities are carried out by “Environ” in the design and manufacturing of aerators so that more and more oxygen transfer per HP per hour is achieved by the aerators.

Environ believes for any energy efficient aerators, apart from the criteria of more oxygen transfer per hp per hour, mixing criteria is also equally important.

In aeration tank, the oxygen, which is delivered by the aerators, should be mixed thoroughly throughout the volume of the aeration tank. Hence, Environ energy-efficient aerators are also a good mixer. So, it also avoids the development of SEPTIC condition at bottom or any corners of aeration tank & hence efficiency in BOD & COD reductions of the effluent are achieved.

We believe when the side water depth of aeration tank is more than the standard one, the design of the impeller of aerator is required to be changed accordingly. If the design of the impeller is not changed, the development of the SEPTIC condition at the bottom floor level of the aeration tank occurs due to the settlement of dead bacterial mass. Environ changes the design of the aerator impeller when the side water depth is more than the standard one    (2.5 Meters) to avoid the SEPTIC condition at the bottom floor level of the aeration tank.

So, Energy-efficient aerators, not only should take care of maximal oxygen transfer at minimal energy, but also should create rigorous mixing throughout the volume of the aeration tank.

There are many more cases, where we had submitted the energy auditing reports and the reports are under consideration of our clients for economy and energy savings.
