Membrane Cleaners

Aqua Clear Membrane Cleaners

Reverse Osmosis (RO) and Nano-Filtration (NF) membranes are highly selective water filtration agents. Because of this trait, any suspended colloids or sparingly soluble salts may be able to fouled membranes. No matter how effective RO and NF pretreatment is, fouling will inevitably occur, and cleaning will eventually be required. Aqua Clear Water Treatment Specialists has a whole line of specialty formulated membrane cleaners targeted towards a variety of commonly observed fouling instances of RO and NF membranes. All Aqua Clear membrane cleaners are compatible with polyamide thin film composite membranes.

RO and NF membranes may experience a wide variety of different fouling that varies by feedwater source and position in an water treatment system. Lead elements will experience contact with the highest amounts of dissolved and suspended solids, while the tail elements experience feedwater that has been concentrated up and contains a high amounts of salts. For this reason, fouling that occurs within one system may be completely different based on position. For example, a lead element may eventually foul with biological or clay fouling, while a tail element in the same system may foul with scale. Past Aqua Clear and membrane manufacturer studies have shown that cleaning when a 15% increase in differential pressure, 15% loss of permeate productivity or increase in permeate product dissolved solids will significantly extend overall membrane life. Cleaning on-time considerably reduces the need to replace costly RO and NF membranes.

Aqua Clear provides membrane autopsy services to determine the most effective cleaning regimen for site-specific fouling. If a fouling event occurs, where a previously used cleaning regimen is ineffective, a membrane autopsy would help gain insightful knowledge in cleaning and restoring membrane performance and will provide useful information on how to prevent future fouling events from occurring.

Aqua Clear has both powder formulations and liquid formulated membrane cleaner chemicals. Each membrane cleaner is specifically designed to uplift and remove distinct types of foulant material. Our cleaners are proven to be more effective than generic cleaners. All our cleaners are multi-component, formulas that act synergistically to chelate, dissolve or remove foulant material. Additionally our cleaners are formulated to be buffered and therefore straightforward and easy to use in Clean-In-Place systems. For a specific cleaning regimen custom tailored to target fouling specific to your RO or NF system, contact an Aqua Clear water treatment specialist.

Aqua Clear Membrane Cleaner Products

Acid Cleaners

AC-702L – Aggressive Metal & Scale Liquid Cleaner

  • A multicomponent, low pH liquid cleaner that is specifically formulated to remove calcium carbonate scaling. The cleaner contains a blend of proprietary chelates and inorganic acids which are safe to use on membranes experiencing calcium carbonate scaling. The cleaner is buffered to resist pH change, although pH should be monitored during cleaning. For use in systems where a more aggressive pH is needed.

AC-702P – Activated Metal Powder Cleaner Plus

  • A multicomponent, low pH powdered cleaner formulated to target metal oxides such as iron, aluminum and manganese. The cleaner contains a proprietary blend of chelates, buffers and reducing agents designed to actively remove precipitated metals. Proven to remove metal fouling at an efficiency more than ten times greater than generic acid cleaners. Great for systems using well water as a feed water source and where the primary cause of fouling is precipitated metals. The cleaner is highly buffered to resist pH changes at a great range of temperatures.
