How to calculate the size of the swimming pool sauna filter?

The correct pool sauna sand filter for pool water treatment will be an appropriate size based on the flow rate of your pool, pool pump and surface area of ​​the filter media. All pool sauna sand filter minimum and maximum flow rates that the pump must belong to. Too weak or too much flow and the pool sauna sand filter will not work properly.

In terms of sanitation regulations for swimming pools, the municipal sanitation regulations require a minimum turnover rate of two complete failures of filtered water within 24 hours. Most pool pumps turn around much faster than that which is why some people prefer to use a two speed pump capable of pumping water. The 2-speed pump efficiently uses as little electricity as possible while meeting minimum turnover.

When choosing a pool sauna filter for swimming pool water treatment, it is important to note that the faster the water moves through the piping system, the more resistant the water is to flowing. This means that slower pumps such as low speed pumps in 2 speeds have an increase in flow per unit of power with lower speeds and high speed options. But it is important to note that with a maximum of 2 speed settings the low speed pump will not be able to meet the minimum flow requirement for the pool sauna sand filter to function properly.

Always make sure that the flow rate of the pump does not exceed the designed maximum flow rate of the pool sauna filter. If the pump is too powerful, it will cause too much agitation of the sand inside the pool sauna sand filter and some sand will pass through the multiport valve and end up at the bottom of the pool. If the pool is used for commercial, semi-commercial or high turnover bather applications, then you will want to choose a pool sauna sand filter that will allow you to turn over the entire volume of water at least four times every 24 hours.

This can ensure the quality of swimming pool water treatment. The working principle of the stainless steel sand tank: the filter uses special filter sand to eliminate the tiny dirt in the pool. Consider sand as the key to removing dirt.

Pool water containing suspended dirt particles is pumped into the filter line. Microscopic dirt is captured and filtered out by the sand bed. The filtered clean water passes through the control switch at the bottom of the filter and returns to the swimming pool through the pipeline.

This set of programs is continuous and automatic and provides a complete cycle for the pool filtration and plumbing system. Make the pool water get further evolution. The filtration of the sand cylinder is through the process of membrane filtration, osmosis filtration and amount removal filtration.

The scope of application is swimming pools, water parks, aquariums, agricultural irrigation, freshwater aquaculture, drinking water pretreatment, industrial water purification, and reclaimed water reuse.

----Yes, they can. Silica sand is mainly used for filtration, while activated carbon is mainly used for adsorption. Silica sand is effective for higher water quality requirements. When use them together, silica sand should be placed on the bottom layer, and then activated carbon should be filled on the sand, but the cost of using two media is much higher.
Poolking’s sand filter warranty is 3 years for fiberglass filter,2 years for plastic filter.During the warranty period,if the filters parts have any damage,we can judge the factors according to the photos or videos, then we can offer free parts to replace. If the filters are damaged badly,we will provide a new one.
The pumps and lights are 1 year warranty,the method is same as filters.
After about 5~10days ,or when the reading of the pressure gauge on the pump side of the filter has increased by about 0.2bars since the last backwash , backwash the filter as follows:
1. Stop the pump
2.Close the valves on the suction and return lines.
3.Open the cover of the pump and empty the filter gasket .
4.Refit the cover
5.Open the valve to the drain outlet
6.Turn the lever to BACKWASH
7. Open the valves to the suction and return lines.
8.Start the pump .Rinse the filter for about 1 to 2 minutes until the water in the sight glass is clear .
NOTE : Any electric heater must be off .
9. Stop the pump
10. Turn the lever to RINSE , start the pump and rinse for about 15~30 seconds. Stop the pump and turn the lever to FILTER . This is the normal operating position .
11. Close the drain outlet valve and start the pump . Switch on the electric heater if any .

It combines rare marine animals, amusement equipment and novel themed performances, original African music, Persian Gulf dome and Bengal Bay food, etc. to create a fantastic marine world for everyone.
----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
