pool operator exam 2023 with 100% correct answers

Turnover When an amount of water equal to the total volume of the pool has moved through the recirculation system Turnover Period The time it takes for the total volume of water to circulate once through the recirculation system Turnover rate A measure of the amount of water moving through the recirculation system in a 24 hour period of time. Turnover rate equation volume of pool X # of required turnovers/day Rectangular Pool Volume L x W x 7.48 Circular Pool R^2 x 3.14 (pi) Flow Rate a measure of the water volume passing through the recirculation system over a period of time Flow rate equation turnover rate/ (24 hour/day) x (60 min/hour) Floating Weir allows only one way flow from the pool into the skimmer so that debris does not flow back into pool Strainer basket in skimmer to prevent debris from entering recirculation line equalizer line provided on skimmers to protect the recirculation pump, ensures that the pump is always sucking water and not air. overflow gutters same purpose as skimmer Surge tank stores water that is displaced by bathers entering the pool Recirculation Pump pulls water from pool and pushes it through the filter flow meter Measures flow rate water heater and heat exchangers maintain desired pool water temperatures. chemical feeders and automation adds chemicals directly into the return line in order to maintain pH and disinfection levels in proper range Oxidation Reduction Potential (ORP) The electrical potential required to transfer electrons from one compound or element (the oxidant) to another compound or element (the reductant); used as a qualitative measure of the state of oxidation in water and wastewater treatment systems. ORP is measured in millivolts, with negative values indicating a tendency to reduce compounds or elements and positive values indicating a tendency to ox idize compounds or elements.
