Ⅲ Flocculation
The purpose of flocculation is to uniformly mix coagulated water to produce either settleable or filterable floc and accelerate the rate of particle collisions, causing the agglomeration of electrolytically destabilized colloidal particles into settleable and filterable sizes.
Considerations of flocculation are:
1. Baffling to prevent of flow short-circuiting
2. Tapered

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

1. 폐수처리 계획
1) 개요(槪要)
폐수중에 들어있는 오염물질을 제거하거나 유해성을 없앰으로서 폐수가 유입되는 하천이나 바다에 미치는 악영향을 제거하는 공작이 폐수처리 이다.
2) 폐수조사
○ 공장조사 : 사용되는 원료, 약품, 용수 등을 조사
○ 유량측정 : 시간, 일, 월
