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
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
