River Sands filter sand is sourced from multiple locations in Australia to ensure consistent ideal angularity, size, spherity and hardness for the most efficient filtering of water.
Testing over a number of years has also proven that River Sands 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.
All of River Sands filter sand is processed through a 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.
They are typically packed in 20kg bags, or bulk bags up to 2.2 metric ton per bag. Other than the standard sizes, we are also able to cater to specific custom sized requirements.
