How Do We Determine Filter and Pump Capacity for a Swimming Pool? – Artemis Pool and Fountain Systems

Swimming Pool Filtration and Capacity Calculation

In order to ensure the safe, hygienic, and efficient operation of swimming pools, it is essential to determine the correct filtration system and disinfection capacity. Incorrect or incomplete calculations may lead to deterioration in water quality, increased operational costs, and potential risks to user health. For this reason, technical calculations carried out during the pool design and operation stages must be performed meticulously, taking into account relevant standards and actual usage conditions.

Calculation Report

For this reason, the Swimming Pool Calculation Report has been developed to quickly and reliably calculate the required capacities by taking into account numerous parameters such as pool type, volume, depth, daily operating time, target free chlorine level, balance tank volume, filtration rate, and safety factor.

After users enter only a few basic inputs, the system automatically determines the most suitable salt chlorine generator, filtration equipment, number of pumps, and heating capacity. The results are displayed on screen in a tabulated format and also contribute to the documentation process with the option to download the report.

This report serves both as a technical reference for engineers and architects, and as a practical guide for pool operators. By entering your own values, you can determine the required equipment capacity for your pool and make the most accurate selections with confidence.

In the design, construction, and operation of swimming pool filtration systems, current standards such as TS 13661, UHE 4, DIN 19605 / DIN 19643, and FINA are taken as a basis. This calculation table has also been developed and made available in accordance with these standards.

How Do I Use the Calculation Report?

By entering the characteristics of the swimming pool you plan to build into the yellow highlighted input fields in the Calculation Report, the system determines standards-compliant, actual capacity values for components such as the sand filter, filtration pump, supply nozzles, and heating system.
