Price: £50  

This report is a continuation of a 1994/ 95 UKWIR contract investigating aspects of water treatment plant operation which influence removal or inactivation of Cryptosporidium oocysts. The results have provided further evidence of the effectiveness of conventional water treatment processes for oocyst removal, and have highlighted the importance of the early part of the filter run with regard to the risk of oocyst breakthrough from rapid gravity filters. The objectives of this work were: To assess the use of particle counters as tools to assist in filter operation; To demonstrate the extent to which operational practices on rapid gravity filters can influence the risk of Cryptosporidium breakthrough; To evaluate the performance of slow sand filtration for oocyst removal; To assess the effect of environmental exposure of oocysts on their susceptibility to disinfection; To identify the potential for spores of aerobic bacteria to act as surrogates for oocysts during water treatment.
