SED_BASIN_MON
Sedimentation basin sludge-blanket monitor with a desludge call, rate-of-rise detection and a latched carry-over alarm.
When to use it
Use SED_BASIN_MON when a clarifier, plate settler or DAF basin carries an ultrasonic or optical sludge-blanket detector, and the desludge pump or scraper is to be called on blanket depth rather than on a fixed timer.
