Following the discovery of Cryptosporidium oocysts in some of the raw water sources
supplying Clay Lane Water Treatment Works, it was decided to build an ultrafiltration
plant (at 160 Ml/d, the largest in the world) to mitigate the risk of this passing into the
treated water. This decision was confirmed by the designation of Clay Lane as a site
"at significant risk" from Cryptosporidium following the application of the
Cryptosporidium regulations in 1999. Since the plant was commissioned in April
2001, it has enabled excellent quality water to pass into supply, and this has been
backed up by an integrity testing system to ensure that fiber breakages can be detected
and dealt with promptly. The ultrafiltration unit has allowed the plant to run at a much
higher throughput under high turbidity raw water conditions, without compromising
treated water quality. The membrane fouling that does take place appears to be
organic in nature and further work is underway to gain a greater understanding of the
issue. Includes 4 references, figures.
