Graded Coal
for Glass Colourisation

Graded coal

Product description

Our premium industrial graded coal plays a pivotal role in glass furnaces during bottle production, controlling colour (from brown to green) and minimising variations.

With consistent particle sizing, strict quality control, reliable fixed carbon content and low inherent moisture, C&S Brand Australian graded coal is a cost-effective glass colourisation solution. We collaborate with fellow manufacturers to tailor products for your specific application needs.

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.
