Pool turnover rate refers to the time it takes for a pool’s entire volume of water to pass through the filtration system. This rate is typically expressed in hours. For instance, a turnover rate of six hours signifies that all the water in the pool is filtered and returned to the pool every six hours. Calculating this rate involves dividing the pool’s volume by the filter flow rate.
Maintaining an appropriate water circulation cycle is essential for water quality and swimmer health. Sufficient filtration removes debris, contaminants, and microorganisms, thus minimizing the risk of illness and maintaining water clarity. Historically, adherence to established circulation standards has been a key factor in public pool sanitation regulations, contributing to safer and more enjoyable swimming experiences. Proper turnover ensures chemical distribution and prevents stagnant areas.
