Abstract

Microbiological products used in the wastewater treatment are a set of microorganisms that have good adaptability as well as high consumption ability of pollutants as a source of nutrition for their growth and development. When probiotics are added, the number of beneficial microorganisms involved in wastewater treatment process of treatment plant will be increased, thereby improving the efficiency of pollutant treatment [1]. The native probiotics have been isolated to select the microorganisms with desirable characteristics to assist the system in reducing boot time and enhance treatment performance. This study has applied the BioL probiotics to aerobic systems wihtin the laboratory scope. This probiotic has reduced the boot time of the system from 6-8 weeks to 3-4 weeks. During the stable operation stage, the COD and T-N treatment efficiency are maintained at high and stable levels of 90-97% and 79-86% respectively.
