Particle size distributions of the sand filter media, and the US Silica Sil-Co-Sil 250 ground silica material used in the clogging tests. Sil-Co-Sil 250 test material (median size 45 µm) Filter Sand (median size 700 µm)
Turbidity measurements taken from the effluent of the device during the clogging tests. The initial turbidity values in the tank were about 1,000 NTU, similar to the initial turbidity values in the treated water. However, these effluent values decreased significantly and rapidly during the drainage period, with most of the sediment remaining trapped in the tank on top of the filter sand.
