Pump blockages and rags are a significant barrier to energy and operational efficiencies at pump stations, causing unscheduled shut downs, safety hazards for operators, costly equipment repairs and increased power usage due to a decrease in the pumps’ hydraulic performance. Scottish Water observed these negative effects caused by an influx of wipes and rags throughout a network of area pump stations. Engineers looked to a proven, powerful solution in the form of two JWC Environmental Channel Monster® grinders at one of their most problematic sites.

Here in the post-Flint era of municipal water operations, and for the foreseeable future, the loudest mandate for utilities will be to "get the lead out" of our distribution systems. Until such time that all lead lines are replaced, control strategies will need to be employed.
Accurate measurement of peracetic acid (PAA) in wastewater is critical for the proper dosing of PAA to meet target microbial reduction targets and to ascertain the concentration of PAA in the plant effluent to meet local regulatory water quality standards. This edition of Wastewater Disinfection Forum discusses the current state of the art in the measurement of PAA in municipal wastewater.
