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
gradient and excessive burial, thermogenic processes begin to generate additional carbon dioxide, nitrogen, methane and water. At this point the amount of hydrocarbons or volatile matter has increased and the coal has reached a rank of bituminous (Rightmire, 1984). After the temperature exceeds 210 degrees Fahrenheit carbon dioxide production increases with little production of methane. The therm
About permeability importance
From the inside which will bite flowing in the water
– Gap among is connected each other and from the place which is high flowing with the low-end place
Is caused by with permeation and power affects in stability
(When there is permeation type, gap hydraulic pressure increase -> Effective stress decrease -> Shear strength decrease -> In stability fa
2. Objective
1) To investigate of solid-liquid mixture flow characteristics in a slim hole annulus
2) Effect of pipe rotation, fluid property, annulus inclination on the particle transport velocity, transport efficiency and pressure drop
3. Theoretical background
3.1 Reynolds number
Reynolds number can be defined for a number of different situations where a fluid is in relativ
우유의 유지방은 대부분 직경 0.1-15 µm의 지방구내에 존재한다. 따라서 우유는 oil-in-water emulsion이다. 이로 인해 몇 가지 성질이 나타난다. 즉 어떠한 에머련(emulsion)도 완전히 안정하지 않으며 지방의 모든 이화학적 반응은 각 지방구 에서 독립적으로 시작된다. 지방과 유장(milk serum) 간의 모든 상호
