Sand Filter Media Washing Sand As A Filter Media Biosand Filter Vol. 35, No. 18, on intermittent sand filter columns of 60cm sand revealed that while grain size was the variable that most affected the oocyst effluent concentrations, the depth of sand was also important in removal, and became important for coarser sands (D10 ).
Multimedia sand filter design is different for every project and depends on properties of the process that requires water treatment. Concentration of solids: Higher suspended solids concentration will require lower sand filter loading rates and larger diameter vessels. Discharge limits and destination: The required effluent concentrations in the process stream helps determine the size of ...
Vol. 35, No. 18, on intermittent sand filter columns of 60cm sand revealed that finegrained sand columns (D10 ) effectively removed cryptosporidium oocysts under the variety of conditions examined, with low concentrations of oocysts infrequently detected in the effluent. Coarsegrained media columns (D10 ) yielded larger numbers of oocysts, which were commonly ...
