The optimal solution for effective water filtration in pools and spas

SiLibeads® filter glass beads are used in various areas of pool and spa filtration, including:

• Private pools and hotel pools: Effective replacement for sand or gravel filter materials for crystal-clear, hygienic water.
• Public swimming pools and thermal baths: Optimal hygiene and reduced chemical use with extended maintenance intervals.
• Biopools and swimming ponds: Natural water treatment without excessive use of chemicals.

• Highly effective filter performance: Perfect roundness and homogeneous pore volume for an optimised filter bed and maximum dirt retention.
• Low risk of biofilm: The smooth surface prevents adhesion and thus reduces the formation of germs.
• Extended filter service life: Up to 40-50% longer service life between backwashes saves water and energy.
• Efficient backwashing: Shorter backwash times with up to 40% less water consumption.
• Excellent durability: High breakage, impact and abrasion resistance ensure an almost unlimited service life.
• Safe handling: Virtually dust-free installation, no risk of injury compared to glass granulate.
• Reduced chemical use: Less biofilm means less need for disinfectants and lower operating costs.

Glass beads, also known as filter beads, are an innovative filter medium that is increasingly being used in swimming pool filters. They offer numerous advantages over traditional filter materials such as sand or filter glass. Here are a few points that highlight the use of glass beads as filter beads:

• Efficiency
  Finer filtration: Glass beads can filter smaller particles than sand, resulting in clearer water. Lower pressure loss: They enable lower pressure loss in the filter system, which increases the efficiency of the pump system.
• Cost-effectiveness
  Longer service life: Glass beads need to be replaced less often than sand, which saves costs in the long term.
  Lower water consumption: Less water is required for backwashing because glass beads can be cleaned more efficiently.
• Environmental friendliness
  Recyclable: Glass beads are an environmentally friendly product that can be reused or recycled.
  Chemical reduction: You need fewer chemicals to maintain water quality, which means less impact on the environment.
• Handling and maintenance
  Less clumping: They are less prone to clumping or forming channels in the filter bed, which improves effectiveness and maintenance.
  In use, glass beads are simply poured into the filter container, similar to sand. The specific amount and exact procedure may vary depending on the filter size and type. It is important to follow the manufacturer’s recommendations for optimal results.
  Although glass beads can be more expensive to purchase than traditional filter media, the long-term savings and improved water quality often justify the initial cost. If you value efficiency, sustainability and easy maintenance, glass beads are an excellent choice for filter media.

Filter sand

Glass beads offer several advantages over sand in water filtration, making them an attractive alternative for cleaning and treating water, especially in swimming pools. Here are some of the main advantages:

• Finer filtration
  Larger surface area: Compared to sand grains, glass beads have a smooth and spherical shape, which results in a larger effective surface area. This allows finer particles down to a size of approximately 3 micrometres to be filtered, whereas sand can typically filter particles down to a size of approximately 20-40 micrometres.
• Increased efficiency and energy savings
  Lower pressure loss: The uniform shape and size of the glass beads ensure lower friction and thus lower pressure loss in the filter system. This leads to higher pump efficiency and can save energy costs.
• Longer service life and cost efficiency
  Chemical resistance: Glass beads are more resistant to chemicals and pH fluctuations than sand. This contributes to a longer service life of the filter medium.
  Less replacement required: Due to their durability, glass beads need to be replaced less often than sand, which leads to long-term cost savings.
• Lower water consumption
  More efficient backwashing: Glass beads can be backwashed more quickly and efficiently than sand, which reduces water consumption during the filter cleaning process.
• Environmental friendliness
  Recyclability: Glass beads are a more environmentally friendly product. They can be recycled and reused, resulting in a lower environmental impact.
• Maintenance advantages
  Prevents clumping: Glass beads are less prone to clumping or forming channels through which unfiltered water can pass. This ensures more consistent filtration and simplifies maintenance.
• Handling
  Dust-free filling: Glass beads are dust-free compared to sand and filter gravel, which makes handling easier when replacing the filter medium.

These advantages make glass beads an efficient, cost-effective and environmentally friendly choice for water filtration, which can both improve water quality and reduce maintenance costs.

Glass beads and glass granules are both popular filter media for water filtration, especially in swimming pools. Both offer significant advantages over traditional sand filter media, but differ in their composition and performance. Here are the specific advantages of glass beads compared to glass granules:

• More uniform filtration
  Uniform size and shape: Glass beads are generally more uniform in size and shape, which creates a very uniform filtration layer. This enables more efficient and consistent filtration of small particles.
• Reduced pressure loss
  Smooth surface: The smooth, spherical surface of glass beads results in lower resistance in the filter bed, which means less pressure loss. This can lead to better pump performance and lower energy consumption.
• More efficient backwashing
  Less clumping: Due to their smooth surface and spherical shape, glass beads are less prone to clumping. This facilitates backwashing, as the material is less likely to form solid channels through which water can pass unfiltered. The result is a more efficient backwashing process that uses less water.
• Better water quality
  Finer filtration: The uniform shape and size of glass beads can help remove finer particles from the water than is possible with glass granules. This results in better water quality and clarity.
• Longer service life
  Chemical resistance and durability: Although both glass beads and glass granules are chemically inert and durable, the uniform nature of glass beads can contribute to an overall longer service life for the filter media, as there is less abrasion and breakage.
• Lower tendency to channeling
  Improved water circulation: The spherical shape of glass beads promotes better water circulation through the filter bed, resulting in more efficient filtration. In contrast, the irregular profile of glass granules can more easily form channels through which water can pass unfiltered.

In summary, glass beads can be preferred over glass granules for water filtration due to their uniform size and shape, reduced tendency to clump and channel formation, and their ability to filter finer particles more efficiently. These properties make them an effective and economical filter medium for applications that require high water quality.
