1. Justifications of the proposed schemes -the structural problem& the chemical injection locations
2. Design impeller and tank type affecting energy efficiency, cost, flocculation size. Design Diffuser Walls and Baffles used for Minimizing Short Circuiting
3. Design launder type, structure, sludge and scum model
Filtration의 세번째 key concept 이유: (to promote readily biodegradabl

3. 실험방법
A. Reagents
i. Escherichia coli
Gram-negative, Non-sporulating, Facultative Anaerobic 박테리아로 37°C 정도에서 가장 활발하게 생식한다. 최적의 환경에서 20min. 정도의 Generation Time을 가지며 주로 대장에서 기생한다.
ii. Yeast
Chemo-organotrop
침전시켜야함을 인지하고 참고논문을 이용하여 STM(Sedimentation Time Modeling)을 유도하였다. 이러한 결과들을 종합하여 CMP 폐수의 유입부터 Microfiltration, Electrocoagulation 및 Sedimentation, 마지막으로 최종 pure water까지 공정을 설계하고 실제 산업에 적용 가능하도록 전반적인 Flow Diagram을 이끌어 낼 수 있었다.
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
instrument composition
-Electric furnace
Temperature range:
25°C~1500°C
Heat speed :
Maximum 200°C/min
*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.
