Control periods when plants are unmanned
Many water treatment plants still use manual control for coagulant dosing (usually alum or ferric). Whilst the raw water quality is steady this is an effective method to set a coagulant dose, however, when the raw water changes then manual control of the coagulant dose breaks down, particularly when plants are unmanned overnight or over…

Particle Monitoring to Prevent Cryptosporidia Outbreaks
Particle Monitoring to Prevent Cryptosporidia Outbreaks Improvements in water treatment have greatly reduced the risk posed by possible Cryptosporidia outbreaks following well published outbreaks around the world in the 1990s and later. As part of these improvements most filters have been fitted with turbidity meters that are great at picking up coagulation failures. In some…
