Glass beads of soda-lime glass with polished surface as filter material
Conventional filter material, such as quartz sand or granules, is extremely susceptible to attack by fungi, bacteria, germs, algae and calcification due to its porous, irregular structure. Contaminations and germs settle in the unevenness of the coarse-pore surfaces of the filter material, multiply uncontrollably and indefinitely in the warm pool water. They are never completely removed even during the backwashing process. This requires an unnecessarily high use of expensive and sometimes environmentally harmful chemical disinfectants.
Precise and narrow sieve curves (gradation) enable an application-specific design of the filter bed and dust-free filling of the filters
High breaking strength and abrasion resistance for mechanical and chemical stability
Effective and efficient filtration processes due to optimal hydraulic conditions
Best self-cleaning and fluidisation properties during backwashing
Significant energy and rinse water savings due to shortened backwash time
Reduction of disinfectants and extension of filter maintenance intervals
Long service life of the filter material
Fields of application
High-performance filter material for single-layer, multi-layer, multi-media filtration in water treatment and water recovery systems.
Advantages
more effective filter effect
higher dirt holding capacity
less backwashing
energy and water savings
