treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and water, those free complex carbohydrates turned into fermentable sources through pre-treatment process - saccharification. Then, it can be changed ethanol form through fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasin
기관의장 설계 편
A. 기장설계의 정의
조선소에서 하는 선박의 기관부(機關部) 관계의 설계와 공작. 기관의장 설계라고 하면 일반적으로 배관설계를 말하는 것인다. 구체적으로 기관배관SYSTEM, 기관배관, 기장철의장, 기장 축타 설계로 구분이 된다.

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.

- Korea’s first Advanced Water Treatment Process
- Living water supply (200,000 tons)
- Improved health , sanitation, culture level
- Local economy development

Based on the reinforcement of integration between distributional organizations in producing centers and retail markets (Hanaro marts) thanks to long term partnership, consolidation, EPC system, and XML/EDI System etc., Nonghyup sends to the suppliers d
Grit chamber
Definition
Remove the grit and inorganic matter over 0.2mm in waste water
[ Function ]
Prevent abrasiona and damage of machine equipment
Prevent Piping system blockage
Prevent adverse effect by deposits
Gravity type chamber
Using the gravity and velocity of waste water
Take the deposits to sludge facility, using sand pump
Aeration type chamber
Using centri
It would involve creating large dam-like structure extending from the coast straight to the ocean, with a perpendicular barrier at the far end, forming a large 'T' shape.
The plant is to open the existing dam to allow the circulation and exchange of water between the Lake Sihwa and the sea.
The tidal plant will improve the lake by circulating 60 billion tonnes of seawater annually
Process Selection Considerations
Selection of an activated-sludge process for BOD removal and nitrification is a function of many considerations including specific site constraints, compatibility with the existing process, compatibility with existing equipment, present and future treatment needs, level of capability of the operating staff, capital costs, and operating cost.
