Water filtration in snow making process

Technical snow production

The production of so-called "technical snow" guarantees snow slopes at insufficient existing natural snow.

For the snow-making, water is pumped from lakes, streams, ponds, or reservoirs with high pressure to the ski slopes. The water needed is filtered by the aquaBoll®.

This way the filter protects either the propeller snow guns or the snow lances. The BOLLFILTER automatic filters the pumped off water and removes particles with a size up to 200 µm.

BOLLFILTER to protect pumps, UV systems and nozzles of snow guns and snow lances:

At the heart of each individual snow-making system, the pump station has to work no matter what and regardless of outside conditions. The water supply has to be guaranteed either way.

For one cubic meter of artificially produced snow, up to 0.5 cubic meters of water are required. Depending on the season and weather conditions, water taken from impounding reservoirs or reservoirs often is full of fir, spruce and larch needles, leaves, sand and floating trash. This makes the filtration task extremely challenging.

The global market leader for snow-making systems, relies exclusively on BOLLFILTER. In the pump station, our BOLLFILTER automatics are the first to ensure and, hence, as one of the most important snow-making components in the system, the uninterrupted operation of high-pressure pumps,UV sterilization systems, and snow guns.

These are located far away from the pump station on the ski slopes and are supplied with the clean, filtered high-pressure water via a system of shafts, pipes, and hydrant systems that extends for miles. Snow is created by the fan-driven snow machines (“snow cannons”) or snow lances.

Furthermore, the BOLLFILTER protects the nozzles of the snow gun and the lance head area of the snow lances from blockage. The nozzles of snow lances and fan guns can get backlogged very fast if the purity level of the water is not maintained. And so BOLLFILTER reliably ensures the entire snow production process, from the water extraction from the impounding reservoir, to the actual “snow making” on the ski slope.

Your Benefits
  • Increased efficiency and protection of the nozzles of the snow guns
  • Protection of the high pressure pumps
  • Protection of the UV-systems
  • Service life extension of the components
