The need to more accurately assess filter performance and improve the overall treatment process has led to increased demand for the high sensitivity provided by particle counters. This technology provides unparalleled performance in maintaining the level of treatment necessary to present health risks caused by waterborne parasites, such as cryptosporidium. For all the emphasis on particle counting, water treatment operators have found there are extremely few publications about its methods-until now. A Practical Guide to Particle Counting for Drinking Water Treatment is the first book of its kind to address the latest technologies, equipment and procedures for conducting particle counting in drinking water treatment and related processes.
