Only manufacturer in India who have got in-house Oxygen Transfer testing & Hydraulic testing facility suitable upto 150 HP aerators. As per the Quality Assurance plan each & every aerator & agitator are runned for Two hours before dispatch.
NEW GENERATION OF “ENVIRON” ENERGY EFFICIENT AERATORS
Contributing In Development Of Our Nation & Reducing Global Warming
When Evaluating Aerating Systems, a total performance & cost of operation analysis is critical. The components of this analysis should include an evaluation of the initial capital cost of system installation, all operating and energy costs. & projected maintenance cost. Also included should be an analysis of how well the system performs the four basic functions required of all Aerators:
A detailed evaluation will quickly reveal that diffused aeration systems are able to perform only one basic function reasonably well. On the other hand, Environ Energy Efficient Aerators accomplishes all four goals excellent mixing, operational flexibility & a life expectancy of 12-15 years with minimal maintenance.
Point to be consider :
Diffused Aeration System have gained popularity based on only one aspect of their performance: they provide high oxygen transfer efficiencies in CLEAN WATER. But the waste water is not clean. A fine bubble Diffused system which performs efficiently in clean water instantly becomes less efficient in waste water. Over a few months or so, the degrading of oxygen transfer efficiency becomes more pronounced until, eventually, the diffusers porous membranes will need to be cleaned manually. This is an undesirable & time consuming maintenance operation. Surface Aerators, unlike diffusers, never foul & will provide the same high oxygen transfer rate along with mixing efficiency with minimum & economical running & also saving in Energy over the life of the equipment.
In Diffused Aeration System, as the Blower blows hot air, the temperature of the effluent rises by 5oC to 8oC due to which the Oxygen Transfer Efficiency reduces. While in Mechanical Aeration System, the temperature of the effluent reduces by 5oC to 8oC & hence Oxygen Transfer Efficiency increases.
The distribution of AIR is not equal in Diffused Aeration System. While, the air is equally distributed in all the 4 corners of the Aeration Tank by Mechanical Aerators.
WHY & HOW ENVIRON FIXED & FLOATING TYPE AERATORS ARE ENERGY EFFICIENT?
Each & every Aerator Impeller has its own Limitations & capacity to cater particular depth of say 2.5 mtrs. – 2.75 mtrs., but as per our experience, if the tank depth is more than 2.75 mtrs., then there will be settlement at the floor level, which will create septic conditions & the D.O level goes down to ZERO, which all the Aerator Manufacturers, ETP/STP Designers, Consultants, Experts will agree.
Now a days, as due to the space constraint, most of the Aeration Tanks are designed with higher depths. As the depths of the Aeration Tank is more than 2.75 mtrs. Environ believes that it is the duty of the Aerator Manufacturer to change the design of the Aerator Impeller considering the depth of the Aeration tank, but it is not possible without doing the experiments OR R&D.
At Environ, we are the only manufacturer in India, who has got R&D Division; therein we are carrying out the Oxygen Transfer test as per American Standard & Wrinkler’s Procedure, before placing the prototype Aerator in the market. No other manufacturer have such in-house oxygen transfer testing facility, the reason for this is, Environ firmly believes that the Aerator manufacturer should know (before offering the Guarantees) the Oxygen transfer efficiency of the Aerator which is designed & manufactured by them. This is not possible without conducting Oxygen Transfer test.
Secondly, in our testing facility, we run all the Aerator & Agitators for 2 hours, as per our Quality Assurance plan. We have also offered the D.O test for the Aerators in presence of our clients against their orders:
In our R&D, we have designed & developed an Aerator with dual impeller, which can offer the result upto 6 mtrs. SWD. In this Aerator Impeller, we have provided one Oxygen & the second Impeller is provided at the bottom, there will be no settlement at the floor area of the aeration tank. Secondly, as the mixer is provided at the bottom, the mixing efficiency is increased due to which the Oxygen transfer rate increases & as the oxygen transfer rate is increased the required HP is reduced, hence energy saving. We are first, in India to introduce energy efficient aerator, which works upto 6Mtrs. SWD, it is Purely an INDIAN TECHNOLOGY having very simple & low maintenance assembly. This aerator offers an excellent opportunity to reduce the operating energy cost. This is possible in ENVIRON Aerator, as we are providing additional featured in our Aerators.
SAVING IN ENERGY & MONETARY SAVINGS
Environ energy efficient aerators have offered the required results as per the Norms of PCB.
