SiLibeads® filter beads – the innovative solution for drinking water purification

SiLibeads® filter beads are used in various drinking water production applications, including:

• Well construction: Efficient filtration and support in drinking water wells to ensure high water quality.
• Water treatment: Used in various water treatment processes to improve drinking water resources.

The advantages of SiLibeads® filter beads over standard filter gravel are:

• Optimal shape and surface: The nearly ideal spherical shape with a smooth surface reduces the build-up of incrustations and decreases the frequency of well regeneration.
• High breakage resistance: SiLibeads® have a breakage resistance that is 10 times higher than that of filter gravel. This prevents breakage, undersized grains and colmation particles.
• Limited grain distribution: SiLibeads® are available in different sizes so that the bead size can be optimally adapted to the soil conditions.
• Purity and safety: Free of impurities and heavy metals, SiLibeads® show no toxicological element concentrations when used with acid-based regeneration agents.

Glass beads are used in drinking water wells for several reasons, which mainly focus on the following:

• Support layer: Glass beads can be used as an effective support layer in drinking water wells. Their smooth surface and uniform shape enable efficient retention of particles from the rock. Compared to traditional sands and gravels, glass beads can provide a better support layer as they are less prone to clogging and allow for a more efficient flow rate.
• Durability and maintenance: Glass beads are chemically inert and do not corrode or decompose in water. This makes them a durable option that requires less maintenance than other fillers. Their durability means they need to be replaced less often, saving costs in the long run.
• Environmental friendliness: Since glass beads are often made from recycled glass, they offer a more environmentally friendly alternative to other fillers. Their longevity and resistance to breakage help to reduce their environmental impact.
• Reduction of biofilm and algae growth: The smooth surface of glass beads can inhibit the growth of biofilms and algae that can form in sand/gravel. This helps to maintain water quality and reduces the need for chemical cleaning agents during regeneration.

Overall, glass beads in drinking water wells contribute to the efficiency and effectiveness of the borehole, improve water quality and are a sustainable, low-maintenance option.

The use of glass beads in drinking water wells not only offers advantages in the support layer itself, but also during well regeneration:

• Easier regeneration: Compared to traditional fill media such as gravel, glass beads enable easier and more efficient regeneration of the system. Their smooth surface prevents the ingress of contaminants, which makes it easier to wash out and clean the beads.
• Less prone to clogging: Glass beads are less prone to clogging because they have a lower surface roughness than gravel. This extends the intervals between well regeneration, thereby reducing maintenance costs and effort.
• Longer service life of the well system: Due to their chemical inertness and mechanical stability, glass balls contribute to a longer service life of the entire well system. This results in less frequent replacement cycles and lower long-term costs.
• Sustainability: Glass beads can be regenerated and reused multiple times, making them a more sustainable option compared to other fillers that may need to be replaced more often due to easier wear and tear and higher material breakage.
• Reduced chemical use: Since glass beads minimise the growth of biofilms and algae, the use of chemicals for cleaning and disinfecting the fountain water can be reduced. This not only helps protect the environment, but also lowers operating costs.

In summary, glass beads not only improve performance in drinking water wells, but also offer significant advantages in well regeneration. They facilitate maintenance, increase regeneration efficiency, extend the service life of the extraction system and contribute to more sustainable water treatment.

Glass beads can actually facilitate the so-called ‘desanding’ or ‘running-in’ of wells, which are processes carried out when new wells are put into operation or after maintenance work on existing wells. Here are some advantages that glass beads can offer in this context:

• Efficient particle removal: Desanding removes fine sand and sediment particles that may have entered the well during construction or maintenance. Glass beads can help to pass these particles through quickly and effectively, as their smooth surface and uniform size enable efficient grain passage.
• Reduced risk of blockages: Compared to other fillers such as sand or gravel, glass beads have significantly better hydraulic behaviour. This is particularly advantageous when running in a well, where there is an increased amount of fine particles.
• Improved stability of the support layer: Glass beads can form a stable support layer, which reduces the risk of channeling (i.e., the formation of paths with low resistance in the filter material). A stable support layer is crucial during desanding and running in a well to ensure evenly distributed filling.
• Durability and low maintenance: Since glass beads are chemically inert and do not wear out, they last longer and require less maintenance. This is particularly important in the initial phase of well operation, where frequent maintenance could be problematic.

Overall, glass beads not only facilitate the desanding and running-in of wells, but also make these processes more efficient and cost-effective. They help to improve water quality and optimise commissioning and maintenance processes.
