Abstract
AbstractParticle counters are widely used in the water industry and generate a significant amount of data. To be useful to operators, such data need rapid interpretation. This paper describes how poor individual filter performance can be detected from particle‐size analysis of the combined filtrate from a block of six rapid‐gravity filters. Relationships between particle counts in the 2–5 μm size range and total count are explored, and the concept of an onsite real‐time alarm system, monitoring differential particle‐count data from combined filtrate, is developed.Consideration is given to the frequency of data collection. Whilst all major events were detected by collecting regimes with collection frequencies varying from 5 to 45 mins, it was found that the governing factor in determining collection frequency is the response time required by the operator to an incident.
