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

옛날에는 사람도 동물과 마찬가지로 손톱을 자신의 몸을 보호하는 무기로 사용하거나 나무에 오르거나 음식물을 채취하는데 사용하였으나 오늘날 손톱은 미용 패션 액세서리로 이용되고 있다.
매니큐어와 인조 손톱은 생활 주준 향상과 미에 대한 관념의 변화로 일반인들에게도 인기

Advantages & Disadvantage
The atmosphere shields us from the sun's cancer-causing ultraviolet (UV) radiation and also moderates the earth's climate.
The atmosphere is obviously vital for human existence, but we have nevertheless been polluting it for years.

The atmosphere can be divided vertically into four m
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
