The special role of the filter sand tank in the water treatment of the water park


The water playground project is an essential part of many large-scale comprehensive playgrounds. It is also the main source of income for some children-themed parks and playgrounds in summer. The most important expenditure of water projects is the water treatment part.

The filter sand cylinder plays a very special role here. The main treatment indicators of playground water treatment include residual chlorine, ammonia nitrogen, turbidity, total bacteria, etc. Residual chlorine can be reacted by some additives such as sodium thiosulfate, and ammonia nitrogen can be eliminated by mixing with ozone.

The more common equipment is the ozone generator. The problem of the total amount of bacteria can be removed by either an ozone generator or an ultraviolet sterilizer. Ultraviolet sterilizer can not only sterilize and disinfect, but also effectively remove green algae in water.

Make the water clear. This is very important for outdoor swimming pools or playgrounds. However, the main problem of water treatment in playgrounds comes from the dirt, hair and other things that stay in the water after tourists play.

In this kind of engineering design, we generally have a water intake, and the water pump is used as the power source, which can be designed at a certain position under the water surface. The filter sand cylinder is connected behind the water pump. The filter sand cylinder can be made into one level or multi-level.

If the head of the water pump is high enough, it can drive two filter sand tanks connected in series. The sand filling method of these two filter sand tanks is generally: the first sand tank can be filled with relatively coarse sand, and the second sand tank can be filled with relatively fine sand. In this way, the larger particles of dirt can be filtered out by the first filtration, and fine filtration can be carried out by the second filtration.

If you want to take into account the removal of residual chlorine and other factors , The activated carbon filter can also be connected in series behind the sand filter as a backup. The filter sand cylinders produced are generally made of stainless steel, and the joints are PVC union type or flange type. The advantages of the stainless steel sand tank: 1. The stainless steel sand tank is not bad forever, and the effective service life is at least 50 years.

The life of the glass fiber sand tank is 5 years; 2. The stainless steel sand tank is very environmentally friendly and will not cause secondary pollution to the water quality. The glass fiber sand tank will slowly dissolve, causing secondary pollution to the water quality, and the glass fiber dissolved in water will cause serious damage to the human body, and is a strong irritant and a strong carcinogen. The use of glass fiber sand tanks has been banned in developed countries; 3. Stainless steel sand tanks are very corrosion-resistant and are the necessary filter equipment for mariculture and aquariums, while glass fiber sand tanks cannot be used for this purpose; 4. The effectiveness of stainless steel sand tanks The temperature resistance can exceed 300 degrees, while the temperature resistance of the glass fiber sand tank is only 43 degrees; therefore, it is the preferred filter equipment for hot springs; 5. The surface of the stainless steel filter sand tank is smooth and the texture is excellent, which can effectively improve the grade of swimming pool equipment; 6. Stainless steel sand tank The cylinder can be customized for any flow rate equipment.

In terms of model selection, we can first calculate the water flow rate we need. Then select the appropriate sand filter tank according to the flow rate. In practical applications, filter sand tanks with larger filter areas should be selected.

Because when the filtration area is larger, the thickness of the sand layer will also increase, and the overall accuracy of filtration will be greatly improved. Of course, the final filtering effect is related to many factors, and the filtering area is only one of them.
