it winds its way through the tank.
As the wastewater goes through the system, BOD and organics concentration are greatly reduced.
Variations to this method include: adding return sludge and/or in decreasing amounts at various locations along length of the tank; wastewater BOD is reduced as it passes through tank, and air requirements and number of bacteria required also decrease accordingly.

아데노바이러스(denovirus)는 아주 병독성이 강한 바이러스로서 아데노이드(adenoid) 조직에서 1953년 처음 발견되어 그 조직의 이름을 따 ‘아데노바이러스’라고 명명되었다. 현재까지 다양한 척추동물에서 50종, 100여 개의 그룹이 발견되었다. 사람 아데노바이러스는 주로 소아에서 호흡기 질

모든 병원균과 유해 바이러스 등은 우리가 생활하는 그 어디든지 있다. 점심을 먹으러 들어간 식당의 식탁에도, 아침저녁으로 출퇴근하는 지하철에도 수시로 몸속을 들락날락 하면서 허약한 조직이나 세포가 없으면 그냥 나가는 것이고, 방어력이 부실하여 비비고 들어앉을 틈이 있으면

Examination about using possibility of high pressure which can promote the quality improvement by microorganism, enzyme activation, fresh flavor, color, functional matter above 500MPa
Digestion tank production gas is a biogas produced by artificial anaerobic digestion of organic wastes with bacteria in the digestion tank. This can be divided into mergence gas which produce bio-gas by putting more than two of them together, among the organic waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic waste. Because they are artificial
③ 항생제를 이용한 미생물 성장 조절
Antibiotic sensitivity 는 박테리아의 antibiotics 에 대한 감수성을 표현하는 것으로 Antibiotic susceptibility testing(AST)는 antibiotic이 bacterial 감염에 대해 효과적인 가를 결정하는데 사용한다. 이를 위한 실험에는 Kirby-Batuer method, Disk diffusion method가있다. 그리고 Liquid dilution test
