The methods of traditional sewage treatment try to use bacteria (from sewage or sludge) to decompose pollutant. But most traditional sewage treatments have great limitation, due to the effective microorganism species、numbers and bacteria capacity are insufficient, resulting in treatment effects that are instable and ineffective. The new generation microbiology engineering - HSB microorganism consists of 101 bacteria species (Taiwan R.O.C Patent Right No. 52123 & I240703) that through screening and domestication, would constitute a variety of microbial food chain, according to formulations of the compound derived from bacteria for different sewage conditions, can handle a variety of difficult wastewater, including direct bleaching and the elimination of ammonia, nitrogen, nitrate, odor, toxic substances , sulfate(SO42-) without having to add chemicals to help the process of coagulation.
