Lavasol™

Lavasol™ liquid membrane cleaners effectively 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. Our Lavasol product line includes eight formulations designed to serve varying system needs.

Lavasol™ 1 is a low pH (acidic) liquid formulation, combining select chelants and solubilizing agents to remove metal hydroxides, carbonates, phosphates and other similar scales. Lavasol™ 1 provides broad spectrum scale removal, and is ideal for situations where limited information is available on foulant make-up. Combining Lavasol™ 1 with an alkaline cleaner such as Lavasol™ 2 for particulate and organic removal provides a comprehensive cleaning. If a more aggressive low pH cleaner is needed, try OptiClean™ H.

Benefits & Features

  • Concentrated cleaner for most efficient shipping and handling
  • Phosphate-free formula to reduce negative impact on the environment
  • Buffered pH to maintain optimum cleaning performance throughout cleaning cycle
  • Best results when used in a program that includes either Lavasol™ 2 or OptiClean™ B

Uses

  • For use on reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF) and micro-filtration (MF) membranes
  • Formulated to dissolve inorganic precipitants from the membrane surface
  • To chelate and remove oxides of iron and aluminum from the membrane surface

Lavasol™ 5

Lavasol™ 5 is a low pH (acidic), low foaming liquid cleaner devised to remove silica and other inorganic scales present on polyamide thin-film composite, cellulose acetate or ultrafiltration membranes. Silica is inherently difficult to remove, but Lavasol™ 5 was specifically formulated to target and remove tough silica scale, while helping remove other inorganic scales present. For systems where predominate inorganic scale is not silica, it is best to use a broad spectrum low pH cleaner (Lavasol™ 1 or OptiClean™ A) prior to Lavasol™ 5. For a comparable powder cleaner, try OptiClean™ S.

Benefits & Features

  •  Extremely effective silica specific cleaner
  • Phosphate-free formula to reduce negative impact on the environment
  • Can be mixed with other low-pH cleaners such as OptiClean™ A or Lavasol™ 1 for a multifunction cleaning
  • Buffered pH to maintain optimum cleaning performance throughout cleaning cycle
  • Proven to efficiently remove silica scale

Uses

  • For use on reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF) and micro-filtration (MF) membranes
  • For effective removal of silica fouling from polyamide membrane elements
  • When simple alkaline cleaning does not produce a clean membrane surface Lavasol™ 5 should be applied
  • Will also dissolve inorganic scales as Lavasol™ 5 is an acidic formulation
