“We gathered initial information about glass filter beads at Interbad 2012. Together with our plant engineer and service partner (KWS, Berlin), we then planned the conversion of a first filter to glass beads. The manufacturer and supplier of the beads touted various advantages. On the one hand, there was talk of water savings due to the better rinsability of the beads, and on the other hand, the higher absorption capacity compared to the dirt load was mentioned.
Both aspects were interesting to us. If the beads could indeed be rinsed better and the filter bed could absorb more dirt, this would improve the operation of our existing plant and also bring savings potential.

In order to test the properties of the glass bead filter material, we decided in 2013 to convert the filter of the most heavily loaded water circuit, that of our outdoor hot tub, to glass beads.

The results convinced us, so in 2014 we converted another water circuit and, in September 2022, all the remaining filters in our paddling pool, including the combi blocks, to glass balls.”

Excerpt from the 2023 image brochure:

‘Technically, the Plantsch is state-of-the-art. Hygiene and safety have always been top priorities. The Plantsch was often the source of ideas, a pioneer and co-developer of new standards for many technical innovations that only found their way into DIN regulations or other pools much later.’

“In May 2020, we installed SiLibeads filter glass beads in a 2.7 m filter. This filter treats the water in our non-swimmer and leisure pools. Both pools are indoor pools. The filter is a multi-layer filter with a Hydroanthrazit H layer. The filter bed height is 1.5 m. As we had no previous experience with glass beads, we regarded the conversion of this filter as a test and pilot project.
Initially, we were sceptical as to whether glass bead-based filtration would work. The additional costs also gave us pause for thought.

We have come to appreciate the smooth and reliable operation of the glass bead filter and are delighted with its low-maintenance operation and good water values. The advantages and performance of the glass beads have convinced us in the long term.

Based on this positive experience, we switched the next water circuit to SiLibeads filter glass beads in January 2023. As part of our regular maintenance programme, we plan to switch all filters to SiLibeads filter glass beads.”
