WebThe design and sizing of the pilot plant was guided by Wegelin design criteria. Gravel was used as a control medium as one of the most commonly used roughing filter media. In order to improve the performance of roughing filters, this process was modified by applying locally available material like charcoal as the filter media. Websizes and distribution and to test a pilot horizontal roughing filter™s (HRF) effectiveness at removing turbidity from highly turbid dugout water. Among the four dugouts tested in NRG, they typically have high concentrations of non-setttleable colloidal (< 1µm) and small supracolloidal particles (< 10µm).
