Fouling-Resistant Coatings Reach Standard Product Tiers
Fouling-resistant surface coatings, once reserved for premium reverse osmosis applications in challenging feedwater conditions, are reaching standard product tiers as coating costs fall and water utilities demand longer membrane life without frequent chemical cleaning cycles. These coatings reduce the biological and mineral fouling that historically shortened membrane service life and increased energy consumption as fouling built up over time. Major membrane makers including DuPont and Toray have expanded fouling-resistant production capacity over the past two years, and utilities report fouling-resistant membranes now specified on roughly one in three new desalination procurement contracts.
Market Impact: Adds 2,800 new desalination facilit
