Ⅰ. Hotel structure
1. Chain hotel
Hong kong-based Mandarin Oriental traces its history from 1926 when its first owner, Hong kong Land, acquired the Gloucester Hotel in Hong Kong. In 1974, the group expressed its intention to expand into the rest of Asia with hotels that reflected the Hong Kong Mandarin Oriental's standard. The group went though various corporate changes. Eventually part o
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.
Also,
Sewage that has been aerated
and agitated in order to promote the growth of beneficial microorganisms that break down organic matter.
The activated-sludge process is a
biological method of wastewater treat-ment that is performed by a variable and mixed community of microorganis-ms in an aerobic aquatic environment.
Purpose: to remove settleable organics and floating scum (gr
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

Rich taste of ice cream and freshness of waffle
Cold Stone’s ice cream has a high viscosity than regular ice cream, so it steadily clings to the mouth. And various mix-ins mixed with the ice cream give it a great biting texture and good smell. Also the waffles from Cold Stone are crisp, fresh, and smell good because each store bakes them
*NOTE: 무차원수란? 차원이 없는 수. 현상 인자를 적당히 조합하면 차원이 상쇄되어 무차원 수치항이 얻어진다. 이를테면 물리적으로 관측되는 양은 반드시 차원을 가지고 있다. 그러나 이러한 양을 더하거나 나눌 때 무차원의 단순한 수가 얻어지는 경우가 있다. 이것을 무차원수라고 한다. 가장 간단한
3. ‘무조건 하면 된다’라는 자기 과신을 경계하고 무분별한 벤치마킹을 조심
인천공항이 최근 계속해서 우수한 평가를 받은 것이 직원들 사이에 혁신에 대한 높은 의지와 자신감을 가질 수 있는 긍정적인 면도 있지만 이러한 자기 과신이 ‘무조건 하면 된다’라는 환상을 형성하여 무리한 사업추진
