Effectively remove inorganic scale, metals, colloids, biological growth, and organic foulants from RO membranes.
Lavasol™ liquid membrane cleaners remove a wide variety of foulants from polyamide thin-film composite and cellulose acetate membranes. Each cleaner dilutes quickly and easily to form a solution that vigorously removes membrane foulants without harming the membrane surface. A regular maintenance program including Lavasol membrane cleaners ensures optimum system performance and maximum element life.
Lavasol I™ is a phosphate free, low pH cleaner designed to remove inorganic scale and metals from polyamide thin-film composite and cellulose acetate membranes.
Foulants effectively removed by Lavasol I include:
- Iron
- Barium Sulfate
- Metal Oxides
- Calcium Carbonate
- Strontium Sulfate
- Calcium Sulfate
Lavasol I complies with ANSI/NSF Standard 60 requirements and may be used on potable water systems.
Lavasol II™ is a phosphate free, high pH cleaner designed to remove acid-insoluble foulants from polyamide thin-film composite membranes.
Foulants effectively removed by Lavasol II include:
- Silt
- Colloids
- Organics
- Microbiological
- Acid Insoluble
- Mucilaginous Material
Lavasol II complies with ANSI/NSF Standard 60 requirements and may be used on potable water systems.
