Pool filter balls are innovative filter materials used for treating pool water. Users who frequently employ pool filter balls appreciate their lightweight, elastic, and easy-to-backwash nature. These balls exhibit a strong recovery ability, stable chemical properties, and durability. During water treatment, the fibers are tightly fixed at the ball’s center, extending roughly along its radius. In comparison to sand filter materials, pool filter balls offer advantages such as high filtration speed, minimal head loss, and a high capacity for holding pollutants. This article addresses common questions related to the use of pool filter balls.
Question 1: What is the application value of pool filter balls in deep water treatment of swimming pools?
Pool filter balls possess excellent absorption capabilities. When immersed in water, their absorption remains unaffected. As impurities enter the filter, the strong adsorption force firmly captures them. Subsequently, a substance on the surface reacts with the adsorbed impurities, leading to their degradation and achieving purification. This makes pool filter balls highly valuable in water treatment, particularly in deep water treatment, effectively trapping tiny suspended matter that is challenging to precipitate.
Question 2: What is the filtration cycle of pool filter balls?
Pool filter ball materials have fibers that are resistant to spreading during backwash, making them ideal for high water quality requirements. These balls effectively remove suspended substances in water, boasting flexible and compressible media with a loose upper part and a dense lower part. Their moderate specific gravity allows for easy backwashing with minimal water consumption. Due to the strong interception capacity, the filtration cycle of pool filter balls is at least 3 to 4 times longer than that of quartz sand filter material. When filtering sewage at the same speed, the cycle of pool filter balls exceeds 50 times that of quartz sand filter material.
Question 3: What is the service cycle of pool filter ball materials?
The service life of pool filter balls depends on factors like temperature, pH, and the corrosive composition of the pool water. Enhanced adsorption capacity and a gradual decrease in porosity along the water flow direction contribute to the ideal distribution of large and small pores in the filter layer. The service life also depends on the composition of the pool filter ball and its adaptability to sewage liquids. Typically, replacement is recommended every month due to their strong adsorption capacity, requiring careful packaging for moisture and waterproofing during storage and transportation.
Question 4: How much pool filter ball material is needed?
The quantity of pool filter balls required is influenced by the diameter and height of the pool filter, as well as the diameter of the filter material. The soft nature of pool filter ball material allows for compression, affecting the amount it can hold. Most pool filter ball materials are cylindrical, and their volume can be calculated using the cylindrical volume formula. Multiplying this volume by the volume of the pool filter ball material determines the quantity needed. The bulk weight of pool filter ball material is approximately 60-80 kilograms per cubic meter.
Question 5: What causes fouling in the pool filter ball’s filter tube?
Fouling in the pool filter ball’s filter tube refers to the corrosion and rusting of the metal pipe’s inner wall, affecting water transport. Complex factors contribute to pipe fouling, primarily the interaction between water and metal. High carbon dioxide content, low pH, and corrosive water, combined with iron seedlings and sulfate-reducing bacteria, can lead to rust formation on the pipe’s inner wall. The resulting rust scale, mostly nodular, consists of solid iron oxide on the outer shell and black ferrous oxide and iron sulfide on the inner layer, exhibiting a soft and mushy texture..
