balling
A method of hydraulically cleaning a wastewater collection pipe or storm drain by using the pressure of a water head to create a high cleansing velocity of water around a cleaning ball. In normal operation, the ball is restrained by a cable while water washes past the ball at high velocity. Special cleaning balls have an outside tread that causes them to spin or rotate, resulting in a scrubbing action of the flowing water along the pipe wall.
turbid
Having a cloudy or muddy appearance.
static head
The vertical distance (in feet or meters) from a reference point to the water surface when the water is not moving. Also see dynamic head, dynamic pressure, and static pressure.
residual analyzer, chlorine
See chlorine residual analyzer.
hygroscopic (hi-grow-SKAWP-ick)
Absorbing or attracting moisture from the air.
