Product description
C & S Brand Australian Filter Coal is an industrial Filter Coal with optimal uniformity coefficient, consisting of hard, durable cubic subangular particles, free of clay, shale and impurities.
Manufactured in our plant with consistent particle sizing, it is clean with minimal fines, resulting in lower scraping losses during filter installation and significant cost savings.
Our anthracite-type filter media ensures long-term performance, outperforming softer or chemically unstable alternatives. Upgrading from a mono-media sand filter to a dual-media filter with Australian filter coal achieves a 50-100% increase in water filtration efficiency and a significant reduction in backwash rates.

Australian Filter Coal or Anthracite
At James Cumming & Sons, we’ve identified an Australian bituminous coal that generally outperforms imported anthracite coal, meeting or even exceeding the AWWA B100 standard.
The two key factors for filtering suitability are coal hardness and acid solubility. Our extensively tested Australian Filter Coal, with a proven track record in thousands of treatment plants, is a superior choice for potable, wastewater or pretreatment desalination. Anthracite coal is not essential for durability and filtration performance.
Projects
Sydney Desalination
Plant
In response to declining water levels, Sydney Water obtained approval for a Seawater Desalination Plant. Pilot testing favoured coarse dual-media filtration. We supplied C & S Brand Australian filter coal, on time and to exact specification.
Qurayyat Desalination
Plant
This plant is in operation to address water shortages in Muscat, Oman and surrounds. We supplied 2,210 cubic metres of C & S Brand Australian filter coal, delivered on time, to exact specifications.
Dungog WTP
This was the first contact filtration plant in Australia to use large effective size media, after pilot plant work by the Hunter Water Corporation. It was also the first to use C & S Brand filter coal and remains an industry frontrunner with long-term results, durability and stability.
Barangaroo Lendlease
Grand Casino
We supplied premium C&S Brand Australian activated carbon while transforming a former gas works into a modern casino and hotel, effectively eliminating odours and volatile organic compounds (VOCs), and adding to the evolving skyline.
Mt Crosby
Eastbank
This refurbishment project included converting 20 mono-media sand filters to dual-media filters with C&S Brand Australian filter coal. It extended filter run times, reduced backwashing frequency and improved plant performance, surpassing client expectations.
