기계식 스크루 브러쉬 콘필터를 이용한 조류 제거에 관한 연구 = A Study on the Removal of Algae by a Mechanical Screw Brush Cone Filter

다국어 초록 (Multilingual Abstract)

This study was conducted to estimate the removal efficiency of algae by a mechanical Screw Brush Cone Filter in a lake. The device used a stainless steel cone-shaped filter with a screw brush. The ability of the developed device to remove algae larger than 20㎛ in Lake ChaSa, Gwangyang city was tested from August to September 2014. The results show that the removal rates for chlorophyll-a, suspended solids and volatile suspended solids were 44-87%(mean 61%), 35-54%(mean 40%), and 37-46%(mean 43%), respectively. This study also discusses equipment and device operation costs and device application problems, and suggests in situ. solutions to these problems.
