Perhaps you have recently added more water to the wash screen that precedes your sand dewatering gear to make the rock cleaner. This can result in the loss of +75-micron (+200 mesh) sand to your settling pond. You cannot always cut back on the wash screen water, as the rock may be too dirty and out of spec.

Before use, the sand was washed with deionized water and then dried at 80°C for 24 h under vacuum to remove soluble impurities. To reduce particle size and remove the impurities of the raw sand, it was milled at 500 rpm for 36 h. After ball milling, the sand was then subjected to a purification process.

Assuming a typical filter depth of 1 m and porosity of 0.5, the estimated hydraulic retention time for a slow sand filter would be 1.25 to 5 h. However considering the suggested 1 to 1.5 m of standing water above the sand layer, the HRT ranges from 2.5 to 12.5 h. The HRT rather than the Darcy flux is the most logical parameter for "sizing ...
