Calculate Filter Flow Rate Capacity of Recirculating Diatomaceous Earth Filter System

What is the flow rate capacity of a recirculating diatomaceous earth filter system?

The pool volume is 30,000 gallons. The diatomaceous earth filter system has a total filtering area of 50 square feet. The filtration rate is 3 gpm/per square feet. The turnover rate is 6 hours.

Answer:

The recirculating diatomaceous earth filter system has a flow rate capacity of 150 gpm and can filter approximately 1.8 times the total pool volume of 30,000 gallons in 6 hours.

To calculate the flow rate capacity of a recirculating diatomaceous earth filter system, we can use the total filtering area multiplied by the filtration rate. In this case, the total filtering area is 50 square feet and the filtration rate is 3 gpm/per square feet. By multiplying these two values, we get a total flow rate capacity of 150 gallons per minute (gpm).

Understanding the turnover rate is crucial in determining how much water can be filtered in a given time period. In this scenario, the turnover rate is 6 hours, which means it takes 6 hours for the filter system to cycle through and filter all the water in the pool.

By multiplying the flow rate capacity by the number of minutes in 6 hours (360 minutes), we can calculate that the filter system can filter approximately 54,000 gallons of water in 6 hours. This is equivalent to approximately 1.8 times the total pool volume of 30,000 gallons.

Having a clear understanding of the flow rate capacity and turnover rate of a filter system is essential for maintaining clean and healthy pool water. By ensuring that the filter system can handle the volume of water in the pool within a reasonable time frame, you can effectively keep the pool water free from impurities and contaminants.
