Abstract
There are a lot of studies on biofouling until now. However, few studies focused on the method that controlled the photosynthetic organism growth on outdoor triangle weirs in a sewage treatment plant. We investigated the growth of photosynthetic organisms on the triangle weir of a second sedimentation basin in a sewage treatment plant. In addition, the growth suppression of photosynthetic organisms was investigated through the surface treatment and shape of the triangular weir.
