High Ph Membrane Cleaner (organic)
Crystal Quest High pH Membrane Cleaner is a powerful, specialized solution designed to maintain and restore
membrane performance. Formulated to effectively target and remove organic fouling, this cleaner penetrates deep into membrane pores, dissolving contaminants that can hinder your water treatment system's efficiency.

Key Benefits:
  • Effectively removes organic fouling, visible slime, and odors that can clog membranes and reduce filtration performance.
  • High pH formula is optimized to break down tough organic deposits while preserving membrane integrity.
  • Suitable for a wide range of membrane materials, including polyamide, thin film, cellulose acetate, and ultrafiltration  elements.
  • Regular use helps extend membrane lifespan by preventing fouling buildup, ensuring consistent water flow and quality.
  • ISO 9001:2015 certified for quality assurance.

Dilution Ratio:

Prepare each cleaning solution using a ratio of 1 lb of cleaning powder to 10 gallons of permeate or DI water. If the system is not drained before cleaning, assume that approximately 4 gallons of water is present in each 8"x40" membrane element and 1 gallon of water is present in each 4"x40" membrane element after a thorough system flush.
