Lavasol 7 (High Performance Alkaline) Liquid Membrane Cleaner Brochure

LIQUID MEMBRANE CLEANER 7Benefits• Low foaming formulation• Effective on a wide range of foulants• Compatible with all polyamide RO and NF membranes• Can be used on most MF and UF membranes• Liquid cleaner easily diluted to application strengthUses• For use on reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF) and micro-filtration (MF) membranes• For effective removal of silt and colloids• Effective in removing biological slime and bacterial byproducts• Acid Insoluble, mucilaginous material and sugars• Very effective in dissolving organic materials, oils and greasesSpecificationsAppearance Clear liquidpH (2% solution) 11.5 – 12.5Density (kg/liter) 1.20 – 1.30Lavasol™ 7 is a high performance alkaline liquid membrane cleaner designed to remove silt, metal precipitants, and organics such as oils and greases from polyamide thin-film membrane systems. The low-foaming formulation has strong chelating properties and is buffered to maintain consistent pH throughout the cleaning process. Used in a program that includes an acidic cleaner for inorganic scale and metal hydroxides this highly efficient product provides excellent foulant removal, resulting in longer system run times and increased membrane life expectancy.PackagingPail: 5 gallon/18.9 literDrum: 55 gallon/208 literTote: 275 gallon/1,040 literFor special packaging options, please contact PWT or your local distributor.Company OverviewFounded in 1996, Professional Water Technologies™ develops industry leading products and services for maintaining and operating industrial, commercial, and municipal reverse osmosis and MF/UF systems.

Inspect all cleaning system components to include CIP tank, hoses, and cartridge filters. Flush or replace if necessary. Fill cleaning tank with RO permeate or DI water. Turn on agitator or tank recirculation pump.2. Slowly add Lavasol™ to cleaning tank (1 gal [3.8 L] of Lavasol™ for every 50 gal [189 L] of water). Mix thoroughly. The solution pH should match product specification. If necessary, adjust pH with a membrane–approved chemical such as caustic, citric, sulfuric or hydrochloric acid. The solution should be heated up to 45°C to improve cleaning efficacy.3. Circulate solution in the same direction as the feed flow. Typical circulation times are 30–90 minutes.* PWT recommends cleaning each stage of the system separately. Maximum flow rate per pressure vessel is 40 gpm (152 Lpm) for 8-inch elements and 10 gpm (38 Lpm) for 4-inch elements. Maximum pressure for cleaning is 60 psig (4.2 kg/cm2). 4. In cases of heavy fouling, divert the first 10-20% of cleaning solution to drain to prevent re–deposition of removed solids. 5. Rinse with RO permeate before returning system to service. When returning unit to service, divert product water to drain until any residual cleaning solution has been rinsed from system.*Depending on the nature of the fouling, a soak period may be necessary for optimum results. Please contact PWT or your local distributor for custom cleaning procedure, or consult PWT’s Technical Bulletin 503 for further cleaning recommendations.
