대부분의 별들은 수소기체(H2)로 이루어진 거대한 성간운 속에서 만들어진다. 별 생성의 원료가 되는 성간운은 아직까지 정확하게 밝혀지지는 않았지만, 우리은하와 같은 나선은하 내에서는 밀도파(density wave)가 수축하는 지점에서 형성되거나 거대한 별이 초신성(supernova) 폭발 이후 남은 잔해가 중력적
flash mix. Structural and chemicals.
First, It has structural problems. As you can see the water flow direction, inlet locates downside and outlet locates upside.
Through this, we can know that axial impeller is not suitable. Also, because of wide width of tank, it has poor mixing.
Second, there is a problem with chemicals. PAC is injected with Cl2, so activation of Cl2 must be restricted.
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
