How to calculate the pool sand filter capacity

The sand filter is responsible for the physical purification of the pool water and causes the elimination of polluting particles and impurities in the water, which has a significant effect on the correction and improvement of water quality, and is also among the necessary and practical equipment in the pool equipment industry and It is considered a jacuzzi.
The calculation of the filtering capacity of the swimming pool and jacuzzi depends on factors such as: whether the pool is domestic or public, whether it is indoor or outdoor, the hours of operation of the pool, and the number of people using it. In the following, we will discuss how to calculate the filter sand capacity of the pool; Please stay with us until the end of the article.
The way to calculate the sand filter capacity of the swimming pool and jacuzzi is the same, but in choosing the filter, you should be careful that FRP (fiberglass or polyethylene) sand filters only have the capacity to withstand water temperatures up to 40 degrees Celsius.
Example: The suitable temperature for jacuzzis is approximately between 40 and 42 degrees Celsius, which is different from the temperature of the spa pool, which is between 27 and 30 degrees Celsius.

Calculating the volume of water in the pool and jacuzzi (first step)

To calculate the volume of the pool and jacuzzi, just pay attention to the geometric shape, dimensions, and depth of the pool, then calculate the volume corresponding to the geometric shape of the pool or jacuzzi using the mathematical formula.
Example: If your swimming pool or jacuzzi is a rectangular cube, you can calculate the volume of your swimming pool or jacuzzi with a simple calculation using the following formula.

c * b * a = V (length * width * height = cube volume)
Also, if your pool or jacuzzi is circular, you can calculate its water volume with the help of the following formula.
Volume = Area * Height
Volume = 14/3 * circle radius (to the power of 2) * height
V=π.r2.h

Calculation of water circulation (second step)

The turnover rate depends entirely on the type of pool.
For example, in a home (private) indoor swimming pool, the pool water must pass through the sand filter every 6 hours, which means that it takes 6 hours for the entire pool water to pass through the sand filter.
Please note that the standard of water passing through the purification system during the day and night is different for each pool, but in general, it is about 3 to 4 times a day for private outdoor pools.
In other words, water must pass through the sand filter of private pools at least 4 times a day to completely purify the water of the pool or jacuzzi.

The number of times the water circulates in the pools

According to the following argument, you can calculate the water circulation rate in the pool you are using:

Calculation of the flow rate of the pool (third step)

Before calculating the water flow rate, you should pay attention to the "pool water purification rate" parameter.
The time it takes for the entire volume of pool water to completely pass through the sand filtration filter is called the pool water filtration rate.
Of course, this calculated time for water to pass through the sand filter does not mean that the entire volume of water passes through the sand filter, but according to the average obtained through experiments and experience, between 50 and 60 percent of the water is purified and in the same proportion The water quality improves and after 6 or 7 continuous repetitions, the entire volume of water is completely purified.
Now, with the help of the obtained pool water purification rate, you can calculate the pool water flow rate.
To calculate the pool water flow rate, you need to divide the pool volume by the pool water treatment rate.
Therefore, it can be concluded that the flow rate has an inverse relationship with the pool water purification rate, and the higher the filtration rate, the lower the filter sand flow rate.

Obtaining the diameter and height of the sand filter (fourth step)

In the table of technical specifications of all sand filters, the diameter and height of the sand filter are mentioned, which you can use to calculate the capacity of your sand filter.
Otherwise, you can calculate the diameter of your filter sand with the following guide:
To calculate the diameter of metal filter sand:
For every 0.93 square meters (10 square feet) of filter sand surface, we consider a flow rate of about 5 gallons (20 liters) per minute.
To calculate the diameter of fiberglass filter sand:
For every 0.93 square meters (10 square feet) of filter sand surface, we consider a flow rate of 15 to 20 gallons (60 to 75 liters) per minute.
Also, the height of the sand filter is 1.2 times the diameter of the same filter.
