Practical Engineering Combined with Sound Operations Optimizes Phosphorus Removal   Water Engineering & Management April 2002   Daniel Bolduc and James Fitch, P.E.
Built in the early 1970s, The Oakland, Maine, Wastewater Treatment Facility (WWTF) treats and discharges approximately 300,000 gallons per day (gpd) of wastewater to the Messalonskee Stream. The facility was designed as a conventional activated sludge secondary treatment system to be used principally for BOD and TSS removals. The secondary effluent enters the Messalonskee Stream upstream of several impoundments. This practice has resulted in a steady decline in the water quality of the stream as evidenced by increased algae blooms and other signs of euthophication in impoundments located downstream of the discharge.

Plant Fine Tunes Filtration Performance with On-Line W   Water Engineering & Management June 2001   By Joe Guerra
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.
