Mechanical surface aerators are widely used for many applications in modern wastewater treatment. They transfer atmospheric oxygen to the liquid by surface renewal and exchange. This provides the mixing necessary for distribution of the aerated liquid throughout the tank. Mechanical aerators have found favour because they dispense with the compressors, air-cleaning devices, piping, & diffusers, and their maintenance, which are necessary with injected-air systems, and because they fit into a wide variety of tank shapes, not being bound to the depth and width structures common with diffused air systems.
We guarantee the efficiency of our aerators in all aspects on account of sound evaluations of our numerous applications of this equipment.
Our adaptable design makes it possible for our aerator impellers to be retrofitted to any existing (slow speed) aerator system. *This requires INDOFAB’s expert opinion on individual basis.
Wastewater aeration is the process of introducing atmospheric oxygen (O2) into wastewater to facilitate the aerobic bio-degradation of pollutants. The activated sludge process is the most common form of aerobic biological wastewater treatment. This popular process relies on aeration to promote the rapid reproduction of micro-organisms that break down organic matter in the wastewater. Aeration also raises dissolved oxygen levels in the final effluent which in turn helps sustain plant and animal life in the receiving rivers and lakes.
Hence, the efficiency of biological treatment plants depends considerably on the quality and suitability of the aerator used. The major factors to be considered in the selection of aerators are the basin dimensions, the required amount of oxygen and mixing.
Indofab Aerator are deployed to be used in both municipal and industrial wastewater treatment plants, including those of the food, pharmaceutical and petrochemical industries. Indofab’s aerators can be installed in several different tank configurations including rectangular, square and round aeration tanks, etc. Float-mounted aerators are also available, where the liquid keeps varying.
