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
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
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 mixing energy to control of floc size (high to low to prevent flocs breakage)
(1) The structure of flocculator
There are five types of flocculator.
2000 B.C - The first recorded (The Susruta Samhita, Sanskrit writing) water purification began with the Egyptians. It is said that impure water should be boiled over a fire, heated in the sun, have a hot iron dipped into it or purified by filtration through sand and course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m
