Biological systems in a wastewater treatment plant can be enhanced to deliver
improved process efficiency and output in terms of BOD, COD, and nutrient
reduction by the introduction of pure microbial cultures to efficiently oxidize
organic compounds with the aid of molecular O2 into CO2,
water, and a new cell.
The process involves isolating specific strains of microbes (having the potential
to release specific enzymes for breakdown of pollutants) and being dosed in the
existing aeration tank.
The use of such specific consortia can overcome the inefficiencies of the
conventional biological treatment facilities currently operational in sewage
treatment plants.
The Introduction of pure culture microbial consortium will have a cumulative effect
on increasing the biomass activity, growth efficiency, and enzyme production
Pure culture microbial consortium serves to overcome feedback regulation and catabolic
repression, as the products of one microorganism act as a substrate for the other.
The microorganisms (or biomass) are the key soldiers in a wastewater treatment plant /
STP / ETP or Open drains that fight and degrade the pollutants in the wastewater. The
native biomass is always dynamic depending on the incoming pollutant load wherein
different microbes get suppressed or outnumbered or simply die under adverse or stressed
conditions such as toxicity, variable pH, low DO, excessive COD loading, and high (or
low) wastewater temperature leading to poor or inconsistent effluent quality.
Bioaugmentation is the process of incorporating special potent and
highly-efficient microbes specifically designed to target specific pollutants and
address the issues of reduced or lost bacterial populations that impact net
performance.
Bioaugmentation helps in efficiently handling shocks and quick upset recovery
owing to shock loading.
