Recycled glass filtration media for swimming pools is an environmentally friendly product that provides exceptional water clarity and saves water.
Glass recycling requires numerous operations to sort, clean and crush the raw material in order to comply with the stringent requirements of the new glass blowers and molders which traditionally transform used glass into other useful products. A portion of the glass still finds its way to the landfill site as it is too costly to recover. Researchers seeking to find a use for this product discovere
d a perfect application in the water purification industry as a filtration medium. In the last 10 years this alternative to silica sand has become extremely popular internationally as the filtration medium for swimming pools and many other waste water treatment applications. Recycled glass filtration medium is now the standard in many countries around the globe. Glass filtration medium is particularly suitable to the swimming pool industry because:-
Crushed glass has a smoother surface than sand, which enhances flow efficiency and inhibits contaminant build-up. As glass is lighter than sand it also provides increased backwash efficiency. It has a negative charge which attracts positively charged contaminants. Glass is synthetically made and has no soluble components such as those found in some silica sands. So why has glass not been used in the pool industry in South Africa? Simple economics – it is too expensive to import. Waterwell in partnership with Maytronics Australia have now invested in the process locally and have launched this superior product in the SA market.
