This study note wished to introduce special-purpose ship for algae removal that isdeveloped by core technology of our country. The ship is consisted of main frame andadjuvant that can attach and detach as cross (+) shape of a character. The characteristicsof ship are super light weight and low draft. That is consisted of four devices assuction, collection, filtration and recovering units. Among these, filtration used screenfilter (mesh size 30 μm). Also, can separate and remove water and algae by compressionair participle action. Percentage of moisture content of concentrated algal particlewas 85%. Water parted with algae finally is exhausted to water area. Removal efficiencythat compare by chlorophyll-a concentration was about 57% (inflow: 83.2 μg L-1,outflow: 35.8 μg L-1) without physical and chemical pretreatment. Forward, need toachieve effect test in various conditions (algal biomass, flow etc.) for efficiency andtechnological elevation of exclusion device. We wished to contribute in presuppressionsystem construction of massive algal development that manage blue-green algaeoccurrence area effectively, and prevents spread as lower part of reservoir. |
