Ⅰ. 입자 운동
유체는 흐르거나 멈춰있는 기체나 액체이다. 특히 기계적 분리에서는 유체중의 고체입자 또는 액적의 운동이 관여되며, 이와같은 운동에 대해 알 필요가 있다. 기체나 액체 등 유체속에서의 입자운동은 역학적으로 쉽게 설명될 수 있다.

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
in an aerobic aquatic environment.
Purpose: to remove settleable organics and floating scum (grease and oils).
Efficiencies:
Suspended solids 50 – 65%
BOD 30 – 35%
Primary clarifiers are either circular or rectangular. They are very similar to sedimentation basins used in water treatment except that scum removal is always provided in addition to sludge collection.
transportation and longer expiration dates. More critical reason for the expansion is growing demand. Thanks to the technologies, producers could barely meet the explosively grown demand for makgeolli. Last year, when the popularity of the drink was on the peak, Jang-soo makgeolli produced by Seoul Takju could not meet the whole demand, so the company decided to build more production facilities
