RO Water Treatment Chemicals

Membrane protection and cleaning chemistry for industrial reverse osmosis systems.

Membrane-care chemistry

Selected for carbonate, sulphate, silica and metal-scaling risks based on feed analysis and recovery.

Low-pH and high-pH cleaning approaches target inorganic scale, metals, organics and biofouling.

Sodium metabisulphite and related chemistry protect polyamide membranes from residual oxidants.

Cleaning and sanitisation programmes are selected around membrane compatibility and plant design.

Chemical selection and dosage should be based on raw-water chemistry, membrane manufacturer limits, recovery, flux trend and differential pressure.
