Pool water flow rate is an important factor for determining turn over rate and ensuring the pool water is receiving adequate filtration. Flow rate is impacted by a number of variables like the dynamic head loss, clogged skimmers, clogged filters or addition of equipment like cleaners, heaters and sanitization equipment that add to the dynamic head. A flow rate that is unable to achieve proper turnover time can result in cloudy pool water, algae blooms, higher chemical demands and potentially dangerous pool water.

More About Flow Rate

Pool water circulation is important for proper filtration. Water circulation is the very first step for quality and clarity of pool water. The pump pushes the water through the filter, cleaning the water and dispersing the chemicals evenly throughout the pool. The primary function of the filter is to clear the water of dirt, debris, small particles and more. Flow Rate is the measurement of gallons per minute (GPM) of water flowing through the circulation system at a given period of time.

Most pool equipment depends on a minimum flow rate to function properly. Pumps are responsible for water circulation in all swimming pools. If a pool is without a pump or a working filter there no way to remove contaminants, dirt and debris. A pool without filtration is a breeding ground for bacteria, organisms, algae, making it dangerous for swimmers.

When purchasing a new filter, the maximum flow rate of your system should not exceed the new filters capacity. If the flow rate is incorrect, it will damage piping and equipment, cause filtration problems, and create an unsafe swimming environment. High flow rate can affect the performance of sand filters by causing channeling within the sand bed of the filter. The channeling will make the pool water cloudy by allowing dirty water to passed the filter media. High flow rates also cause unsafe levels of force generated by the drains, which could lead to a swimmer or objects becoming entrap by the drain. The Flow Rate is crucial for the filter to work properly

When the flow rate is too low, it causes a poor distribution of disinfectant throughout the pool. Also, the water doesn’t get the recommended number of turnovers allowing breakouts of fungus, algae, viral and bacterial in the dead zones.

Verifying the correct flow rate for the swimming pool is an important pivotal role in properly filtering and disinfecting the pool water.
