aeration basin.
Wastewater Flows through as a plug & is treated as 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 requ

Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma
모든 물질은 순환한다는 점에 착안
Recycling을 함으로써 자연에서 생선된 물질을 다시 자연으로 돌려보내며 생태계의 평행을 유지하고 뿐만 아니라 더욱 비옥한 땅을 얻는 효과도 거둘 수 있다.

Ⅰ. 개요
환경관리의 기본개념은 우선 폐기물의 발생을 최소화하고 재활용이 가능한 것은 재활용하며, 일단 발생된 폐기물은 자연의 자정능력이내의 안정한 물질로 전환하고 감량화시켜 자연의 생태계에서 순환하도록 환원시키는 것이라 하겠다. 이러한 의미에서 최근의 폐기물 처리기술동향은 부

퇴비화는 B. C. 2000년 이전부터 농업생활의 일부분으로서 농가에서 발생하는 분뇨나 볏짚 등의 농업부산물을 더미형태로 장기간 부숙시켜 만든 퇴비를 농경에 재이용 하는 하나의 농업기술이었다. 이렇게 생산된 퇴비가 지력을 높여 농토의 생산성을 높여 주어 동아시아 지역의 높은 인구 밀

Fascinating.
But what is wrong with the car?
My guess is that your stroke is too short
and youre getting premature ignition.

aeration tank. The organic load on the aeration tank, MLSS concentration, and oxygen demand are uniform throughout the tank. An advantage of the CMAS process is the dilution of shock loads that occur in the treatment of industrial wastewaters. The CMAS process is relatively simple to operate but tends to have low organic substrate concentrations(i.e., low F/M ratios)that encourage the growth of f
