Fujian Gulei Petrochemical has completed a retrofit of its water treatment system by reusing ultrafiltration and reverse osmosis membrane elements rather than replacing entire sets, according to China Petrochemical News. The company redistributed serviceable membranes between treatment trains so that partly degraded modules keep working in less demanding positions, an approach it describes as cascade utilisation. The refinery reports significantly lower equipment purchase costs plus stable, high-quality treated water, and has turned the practice into a formal membrane management routine.
