The submersible aerators are installed with help of frame& large 100% virgin HDPE floats. The motor / propeller assembly is totally submerged and generally at a submergence of 0.7m.The high speed propellers create turbulence in the liquid creating a vortex, where atmospheric air is sucked in through air intake pipes. The atmospheric air released in the highly turbulent zone is broken in the form of micro bubbles (of 10 micron size) and this formation of micro bubbles contributes towards the very high efficiency of oxygen transfer.
The Compact Aeration Unit is made of PVC Circular Pipe of 14inch dia and about 1 m height consists of a diffuser and air pumping system (consuming about 40-75 watts of energy) and where the inoculated bacteria grows (over a media), survives, oxidizes and moves with the discharged wastewater. As the air moves through a Polymer Diffuser (at the bottom of the compact unit) it creates micronised air bubbles at a pressure and moves upwards
On its movement upwards, it sucks in the wastewater from the sides and pulls it along upwards. The polymer diffuser present at the bottom of cylinder releases a flow of micronised air that moves upward and pulls the waste water upward. When the organic component of waste water comes in direct contact with microbial growth it leads to its rapid degradation.
The blowers requires lot of maintenance particularly bearings. They need proper lubrication and there is lot of wear and tear. This not only decreases the efficiency of the system but also involves large maintenance cost.
Another important problem with the blower is the aeration grid which is installed at the bottom of the tank for the purpose of oxygen release. It has always been found that over a period of time the aeration grid gets choked by the flocs and either have to be replaced or cleaned. This not only involves exorbitant cost but also breaks down the whole waste water treatment system.
Our submersible jet aerator consumes only 1.0 H.P of power and need to be operated for just 10-12 hours on a daily basis while Blowers will consume 2 H.P of power.
The Blowers cannot run continuously for more than 3 hours and thus have to be interchanged periodically. Thus they require skilled manpower to operate the system.
