OptiClean™ B – 45LB Pail – Powdered cleaner for organic, biological, and silt particulate foulants.



OptiClean™ B is an aggressive high pH (alkaline) powdered cleaner ideal for removing organic, biological, silt, particulate, and other acid insoluble foulants from thin-film composite, ultrafiltration, and microfiltration membranes. Combining select water activated chelants, solubilizing agents, and membrane safe oxidizers, OptiClean™ B provides outstanding cleaning capabilities. Ideal for membrane systems troubled by high organic and/or biological loading, OptiClean™ B is the most aggressive high pH cleaner in the OptiClean™ line, but remains the first choice for many applications. For a comparable liquid cleaner, try Lavasol™ 7.


  • Readily dissolvable powdered cleaner provides 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 OptiClean™ A or Lavasol ™ 1

  • Formulated to dissolve organic precipitants from the membrane surface
  • To aid in the removal of particulate, colloidal, microbiological and other acid insoluble foulants from the membrane surface
