glass beads are a sustainable and environmentally friendly filter medium offering reduced water, chemicals and energy consumption.
Thanks to their round geometric shape and the resulting homogenous filter bed, glass beads have outstanding filtration properties. Modern water well construction has already been using glass beads as a borehole support material in drinking water extraction for a long time. But in addition to drinking water wells, glass beads also make a compelling case in filtration systems for water treatment and recovery. Many installations in private and public swimming pools as well as large industrial plants have proven this extensively.

The advantages of glass beads compared with sand as a filter medium are crystal clear: glass filters even the smallest particles out of the water thanks to its high bulk density, just like sand. But glass beads do not stick and clump together or form channels, and they are easy to clean mechanically by backwashing the filter. This enables a more economical use of maintenance products. Furthermore, because glass has a more open structure, pumping power can also be reduced significantly. The amount of filter medium used can thus be reduced by up to 25%. By the same token, the much shorter backwash duration cuts water and energy needs drastically.
