Anti-Fatberg Coatings

---

Anti-fatberg coatings provide a new solution to prevent accumulation of fat, oil, and grease (FOG) in wastewater systems, thereby decreasing sewer blockages, environmental hazards, and expensive maintenance. These coatings exhibit hydrophobic, oleophobic, and bio-repellent characteristics, thereby rendering sewer surfaces resistant to grease buildup and microbial adhesion.

These coatings rely heavily on nanomaterials and polymer-based layers for their development. Superhydrophobic coatings, inspired by the lotus leaf, inhibit the attachment of FOG to sewer walls, pipelines, and wastewater treatment equipment. Antimicrobial coatings containing silver, copper, or enzymatic agents help break down organic matter before it becomes solid, thereby decreasing the necessity for manual cleaning and chemical treatments.

Beyond traditional wastewater systems, food production facilities, restaurants, and industries with high grease usage benefit from anti-fatberg coatings applied to grease traps, drainage systems, and storage tanks. These coatings reduce equipment failures, unpleasant smells, and health risks, thereby decreasing maintenance expenses and boosting operational productivity.

Developments in anti-fatberg technology are expected to incorporate self-healing, AI-enhanced, and nanotechnology-based coatings that facilitate real-time monitoring and prompt intervention to prevent grease-related clogs. Future wastewater management could be significantly impacted by advancements such as coatings that degrade fat deposits and surfaces that repel grease through electroactive properties. Advances in this field are driving sustainability and urban sanitation, with a focus on efficient and environmentally friendly wastewater systems globally.
