James Cumming & Sons is the sole manufacturer of Australian Filter coal (Anthracite type filter media),
Our coal is produced to particular customer sizing specifications, from a select premium coal seam in NSW with the right characteristics for water filtration media. With over a century of mineral processing and manufacturing, we’re the reliable partner to deliver for effective and dependable anthracite-type filter media for potable, tertiary wastewater, industrial and desalination pre-treatment applications.
C & S Brand Australian Filter Coal is an anthracite-type filter media with industry leading uniformity coefficient (UC), consisting of hard, durable cubic subangular particles, free of clay, shale and other impurities. Lower UCs allow for greater filter run times, ideal void spacing between interstitial particles within the filter bed creating more capacity for floc and therefore longer life of the filter and improved flow rates allowing for less backwashing and more filtration time from your treatment plant.
Manufactured in our Western Sydney processing plant through a dry process 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 coal 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.
Manufactured to Customer Specification as per AWWA B100; Stock Effective Sizes available upon request. ES 0.6mm to 2mm
Manufactured to Customer Specification as per AWWA B100. We can manufacture and supply to uniformity coefficients less than 1.3 maximum through our innovative crushing and screening plant.

At James Cumming & Sons, we’ve identified an Australian bituminous coal that outperforms imported anthracite coal, meeting or even exceeding the AWWA B100 standard, except for the fixed carbon content.
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 pre-treatment desalination. Anthracite coal by classification or rank is not essential for proven durability and filtration performance. Attrition losses through a filter have been proven at 0.25% maximum per annum on 100 hour backwash tests through independent water authorities and laboratories testing.
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 Australian Filter Coal and remains an industry frontrunner with long-term results, durability and consistency.

Yes. We understand the importance of having detailed information for informed decision-making. Please reach out to us with your requirements, and we’ll be happy to provide you with comprehensive data sheets for our Australian Filter coal. Our team can discuss your delivery needs in detail.
While anthracite is often considered a higher grade of coal due to its higher fixed carbon content, our experience across thousands of projects delivering potable water, wastewater and desalination applications has consistently demonstrated the distinct advantages of our select bituminous based coal.
Our Australian Filter Coal has a lower fixed carbon content than Anthracite Coal. However, this is proven to not affect filtration ability. Our Australian Filter coal superior hardness also contributes to greater resistance to abrasion and breakdown, ultimately prolonging the lifespan of the operating filter. Choosing bituminous coal can also be a more cost-effective solution, given the relative scarcity and higher cost of imported anthracite.
Lead times for Australian Filter Coal orders vary depending on factors such as order size, specific product requirements, current stock levels and your location. However, we strive to fulfil orders as efficiently as possible. We can provide you with a precise delivery timeframe upon request. We manage the delivery process along the way, from formal quotation to confirmation of order and prompt shipment.
