Glass Beads Are an Efficient Filter Medium

SWARCOCLEAR filter beads are a sustainable and environmentally friendly filter medium offering reduced water, chemicals and energy consumption.

As a specialist in the production of micro glass beads, the international SWARCO group also makes, among others, filter glass for water filter applications in customized OEM versions for pool system and filter manufacturers and resellers. SWARCOCLEAR filter glass beads have a highly effective filtering effect, and offer clear advantages compared with conventional filter materials.

Thanks to their round geometric shape and the resulting homogenous filter bed, glass beads have outstanding filtration properties.

For centuries, sand and gravel filter media have been used to collect, extract, purify and treat drinking and process water. Filter glass is constantly gaining popularity as an alternative. Thanks to their round geometric shape and the resulting homogenous filter bed, filter 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.

Well Rounded

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.

Efficiency, Quality, Sustainability

SWARCOCLEAR filter beads improve water quality. The filter glass beads have a smooth, closed surface as well as high material hardness and surface quality. As a result, germs and contaminants do not cling on to the filter glass beads permanently. Up to 95 percent of all particles up to 1 µm in diameter are filtered out of the water. SWARCOCLEAR filter beads are made solely from high-grade recycled glass from the flat glass industry. State-of-the-art technologies employed in production reduce energy consumption and emissions and achieve better recycling rates in the raw materials used.

About SWARCO Indusferica

As part of the international SWARCO group, SWARCO Indusferica leverages the universal benefits of glass beads for special industry applications. In 1969 SWARCO started out with the manufacture of tiny reflective glass beads for road markings. Today, the group has grown into one of the world’s leading manufacturers of micro glass beads, with production facilities in Europe, the United States and Saudi Arabia. Micro glass beads serve as high-grade filling agents for industrial applications and as blasting media for surface treatment applications. In traffic technology, micro glass beads which are embedded in the marking materials reflect the beam from the headlight back to the driver, making road markings visible; this enhances road safety, especially at night.
