Brief
Discover how a zinc-enhanced polyurethane coating significantly reduces fatberg build-up in concrete sewer pipes, offering a breakthrough solution to clogged drains.
Insight
Sewage blockages caused by fatbergs are a costly and persistent problem, with up to 40% of blockages attributed to the build-up of fat, oil, and grease (FOG) in sewer systems. Fatbergs are formed when FOG combines with calcium, water, and non-biodegradable materials such as wet wipes and sanitary products. Traditional methods to manage sewer corrosion have inadvertently contributed to this issue.
Researchers at RMIT University have developed an innovative zinc-enhanced polyurethane coating designed to address this challenge effectively. This advanced coating reduces FOG build-up on concrete sewer pipes by 30%, while also significantly lowering the release of calcium—a critical component in fatberg formation—by 80% compared to uncoated concrete.
The coating is durable, stable in water, and capaSewage blockages caused by fatbergs are a costly and persistent problem, with up to 40% of blockages attributed to the build-up of fat, oil, and grease (FOG) in sewer systemsble of withstanding high temperatures up to 850°C. It also features unique self-healing properties, demonstrated to repair surface scratches at 30°C.
This breakthrough technology not only minimises maintenance costs but also enhances the lifespan of sewer infrastructure. With further refinements, the researchers aim to improve the coating’s mechanical strength and FOG-reduction capabilities, paving the way for a sustainable and efficient solution to clogged sewer systems.
