Plant Fine Tunes Filtration Performance with On-Line W

Because particle counting is a more sensitive measurement than turbidity measurement, liquid-borne particle counting is playing an increasing role in potable water treatment. At San Francisco’s Harry Tracy Filter Plant, operators are using a water particle counter to fine-tune filter operations. Based on the successful performance of its online unit, plant management is planning to fine-tune filter runtimes even further by installing additional particle counters to monitor raw water influent as well as individual filter and combined filter effluent particle counts.
