Filter Sand

Our filter sand is sourced from multiple locations including the 400 million year old Logan River System, to ensure we consistently provide the ideal angularity, size, spherity and hardness for the most efficient filtering of water.

Testing over a number of years has also proven that our filter sand has a slow breakdown rate ( thus ensuring a longer filtration life) as well as excellent backwashing characteristics, particularly when used in dual media filtration with filter coal.

Note:- High quartz filter sand can also be sourced from other quarries if needed

Triple Washing and Screening of the Filter Sand

All of our filter sand is processed through our state of the art manufacturing plant for triple washing and pre-sizing. The filter sand is then dried and sized to your specifications by sending it over a series of vibrating screens with effective sizes and uniformity coefficients guaranteed.

And because our filter sand is washed, dried, screened and packaged (to the AWWA B100 -01 Standard) at the one site in Brisbane, we can offer competitive prices and prompt delivery.

Packaging is available in 20kg or bulk bags (up to 2,200 kg per bag).
