Bacteriophage Removal Using Upflow Biosand filer: A Laboratory Study

Ghada Heikal, Rabab Wagdy, Gamal Eldidamony


Biosand upflow filter of removal bacteria and virus has been carried .Different types of sand and gravels, the variables studied were; Different sand particles, bed height, solution flowrate, different flow rate, different bacteria concentrations, and optimum conditions reduction from 549 to 200 MPN, when using flowrate 0.75 ml/sec, the rate of virus removal was 95% by using contact time 1 hour. The bacteria and virus removal was related to the operating variables.
