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.
Also, using alum may cause settling.
Alum lowered pH in localized area. To overcome this proble
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
remove large debris such as sticks, leaves, trash and other large particles
water stored in reservoirs for periods between a few days and many months to allow natural biological purification to take place
salts are treated with soda-ash (Na2CO3) to precipitate CaCO3 out utilizing the common-ion effect
chlorinated to minimize the growth of fouling organisms on the pipe-work and tanks
PHB`s Separation & Purification
Target of this study conducted to obtain a purely material PHB purification process debris in the damaged cells, and to remove the remaining medium components. PHB has been removed during the refining process with just remove the present efficiency of the overall purification stayed in the 70-80%.

flow regime of a continuous-flow stirred-tank reactor. Settled wastewater and recycled activated sludge are introduced typically at several points in the aeration tank. The organic load on the aeration tank, MLSS concentration, and oxygen demand are uniform throughout the tank. An advantage of the CMAS process is the dilution of shock loads that occur in the treatment of industrial wastewaters. T

A BLOOD RED SCREEN - A JAPANESE DRUM starts to play, softly,
but tinged with a desperate edge, growing louder, joined by
other DRUMS as a BLACK LEGEND scrolls up: In feudal Japan,
the warrior class of Samurai were sworn to protect their
liege lords with their lives. Those Samurai whose liege was
killed suffered a great shame, and they
