Running the process: O&M, control, distribution, performance and risk. Equipment design belongs elsewhere.
Focuses on process execution and operational control, not equipment design. Use when the focus is how a process is run and maintained.
Execution, O&M, CT control, network hydraulics, emergency planning, performance management.
Equipment design, technology-family comparison, vendor selection.
CT (concentration × time) is the regulatory metric for drinking water disinfection efficacy. This article explains how to calculate, monitor and optimise CT under variable flow, temperature and pH conditions, with worked examples for free-chlorine, chloramine and UV systems.
Ten checks that prevent most emergency callouts.
Replacing 14 ageing lift-station pumps cut blockage callouts by 71% and energy use by 19%.
District metered areas turn an unmanageable network-wide loss figure into a set of tractable local problems.
Aeration typically consumes 50–60% of a treatment plant’s electricity. Most of that is recoverable without new blowers.
Every curve is measured on clean water at a fixed speed. Here is what suction conditions, wear rings and a worn impeller do to it.
