Wastewater: PeCOD

Laboratory staff have long known the potential negative health impacts associated with chemical oxygen demand (COD) testing using the traditional dichromate method. Mantech’s new PeCOD technology not only eliminates the need for hazardous chemicals, but delivers results within 15 minutes, allowing industrial and municipal wastewater facilities to make immediate adjustments to their processes. “At Mantech, we’re always looking for ways to make things greener, safer, and faster without sacrificing accuracy or quality of results,” said Robert Menegotto [...]

Drinking Water: Pipe Wall Assessment Technology

Municipalities often find repair and preemptive maintenance to be one of the toughest aspects of asset management. There is a need for a screening tool that can evaluate the condition of lengthy metallic pipelines, said Reid McDougall, VP of Pure Technologies’ Canadian region. Typically, this has been a costly and labourious endeavour, leading many utility owners to forego thorough inspections of less critical watermains until they reach a state of significant damage. In response to this need, Pure developed pipe wall assessment (PWA) technology. “The [...]

Conveyance: Model Predictive Pressure Control

The drinking water industry relies on Standard Proportional-Integral-Derivative (PID) control for conveyance, which has a limited ability to simultaneously control multivariable inputs and outputs. Due to this control approach, water pressure fluctuates during water pump starts and stops, which makes utility infrastructure vulnerable to damage, as significant variations in pressure can lead to watermain breaks. The Windsor Utilities Commission (WUC) set out to find a more efficient control methodology that could counteract these pressure deviations, reducing [...]

Water Resources: Electronic Reporting Tool

When water utilities and municipalities report to government regulatory agencies, it usually means long hours of paperwork. The WaterTrax electronic reporting tool automates this process. “WaterTrax allows the people who maintain water quality to put the data from their labs, hand-held instruments, SCADA system, or anywhere they’re collecting data from, into one place,” said Sheena Graham, WaterTrax marketing specialist. Configured with the specific requirements of the relevant jurisdiction, the system organizes the data and allows users to submit reports [...]
