Study of acclimatization and kinetics of pollutant degradation by mixed culture microorganisms in restaurant wastewater

Abstract


With the development of the restaurant industry, a series of environmental problems emerged, including high concentrations of oily wastewater. As a developing country, Indonesia has a large amount of effluent produced that is not processed but is discharged directly to the available pool. In order to handle restaurant wastewater, physical and chemical approaches can be combined with biological degradation (biodegradation). This biodegradation can be increased by bacterial acclimatization, namely by the addition of microorganisms that have been developed that can efficiently degrade pollutants in a contaminated environment. Stages of research were carried out by propagation of bacteria (Seeding), then the acclimatization process was carried out to adapt bacteria to waste, biodegradation process, and calculate the growth rate curve of microorganisms. It was found that the half-saturation constant of mixed culture microorganisms to treat restaurant waste was 41,336, with a maximum growth rate of 0.124 per day.
