The new proposal being introduced in our country is the advanced filtering medium filter glass , designed to replace filter-grade sand in pressure and gravity flow filters .
Switching from sand to filter glass will improve the performance of the filtration system . Glass removes very small particles. Under controlled conditions, using sand at a flow rate of 10 m³/h/m², the sand removed approximately 90% of all particles down to 10 microns. Grade I filter glass, under the same conditions, reduced the particle size to 5 microns. In addition to removing solids through physical processes, it has a negative surface charge that allows it to remove very small particles and organic matter through surface adsorption (glass repels bacteria).
Filter glass is excellent at removing positive ions such as those from iron and manganese. Sand’s performance deteriorates due to surface contamination. However, filter glass is largely self-sterilizing and can be cleaned with approximately 50% less water . For this reason, the lifespan of this system can encompass the life of the filter.
Some benefits:
- It provides better water quality and clarity .
- It removes much smaller particles from the water compared to the equivalent grade of sand.
- Microscopic smooth surface , with catalytic properties of permanent self-sterilization and oxidation properties.
- Less likely to be contaminated by fats, lipids and biological growth.
- In chlorinated systems, the combined levels of chlorine are lower with filter glass and therefore less coagulant is needed .
- Easy to rinse , approximately 50% less water is used to clean the filter glass.
- Very high wear resistance .
This product is very easy to use. It’s a direct replacement in all pressure or gravity flow sand filters . Simply remove the sand and replace it with the filter glass.
