CP069  Membrane Plant Integrity Testing Water Treatment
Integrity testing for membrane plant is a key factor in maintaining operational security and, for "significant risk" sites, is critical for compliance with Cryptosporidium Regulations. Previous integrity testing systems were established to meet 4 or 5 log removal, and the test needed refining to meet user requirements. The refinements needed were to enable better interpretation of data from integrity tests and to make the best use of complementary techniques including particle counting and acoustics.

The objective of this study, carried out for seven water supply companies and utilities was:

  • To provide "best practice" guidance on interpretation and handling of data from integrity tests
  • To develop operational procedures to incorporate the data to maximise security of treatment
  • To identify and refine testing techniques which can provide additional or complementary information and provide guidance on how these are best used.

Benefits

Independently derived and collaboratively agreed best-practice guidance has enabled cost-effective compliance with regulatory requirements.
