%X GAC-sand dual media deep bed dissolved air flotation/filtration (GSDDB-DAFF) is a new integrated process, its characteristics include: integration of dissolved air flotation and filtration, GAC-sand dual media deep bed filtration, integration of general treatment and advanced treatment. When algae-laden raw water was treated with the new process. The result showed that removal percentage of algae was 95.1%, outlet algae-count was 4.30 x 10(5) cell/L. Removal percentage of chlorophyll-a was 92.2%, outlet chlorophyll-a was 0.88 microg/L. Outlet turbidity was 0.18 NTU, removal percentage of UV254 was 54.3%, outlet UV254 was 0.016 cm(-1), Removal percentage of OC was 63.6%, outlet OC was 0.78 mg/L; outlet had no odor; removal percentage of color was 86.4%, outlet color was 3; outlet Al-residual was 0.011 mg/L which accorded with the quality standard of drinking water. Run time of filter was 36 h, UFRV (Unit Filter Run Volume) was 504 m3/m2.
