Cryptosporidium and Water Treatment: Particle and Spore Counting, GAC and ManganeseFiltration and Backwash Settlement
These studies fill a number of gaps in knowledge of removal processes and monitoring of Cryptosporidium during water treatment. The main findings are as follows. (i) Evidence of the potential benefits of spore measurement for further optimisation of plant performance is provided, although aggregation of spores needs to be considerd when interpreting the results. (ii) Floc shear can impair the performance of settlement of backwash water with respect to oocyst removal, but the effect can be reversed use of polyelectrolyte. (iii) Ozonation greatly enhanced particle removal by GAC filters. (iv) Suspensions of latex microspheres provide a practical technique for on- site checks of particle counter calibration.
