By replacing diffusers with energy efficient aerator for its ETP, Oneiro expects to save around ` 4 lakhs in energy cost
At Oneiro Chemicals Ltd., Vadodara, the flow is of 60 KL/day and COD is 8,000 ppm in their effluent. In their Effluent Treatment Plant (ETP), they have two aeration tanks of size 6M x 6M x 4.6M SWD + 0.6M FB. Previously in the aeration tanks, they were using Diffused Aeration System having the blower capacity of 15 HP in each tank. They have lot of maintenance problems like chocking of diffusers, uneven distribution of air, maintenance of blowers, blower making noise, etc. Therefore, they decided to replace this Diffusers with ENVIRON Energy Efficient Aerators.
On studying the characteristics of the effluent and tank size, ENVIRON recommended 7.5HP Aerator in each Tank. Oneiro decided to replace the Diffused Aeration System of Tank No. 1 and replaced the same.
