Performance advantages

Specialization in severe biofouling:

RoClean P111 is specifically formulated to remove severe biofouling, including polysaccharides, humic and fulvic acid contamination. This specialization makes it particularly effective where other cleaners may be less efficient against this type of contamination.

Powder formulation for ease of use:

The powder formulation of RoClean P111 facilitates storage, handling and dosing, offering a practical and efficient solution for the maintenance of reverse osmosis systems.

High buffering formulation:

The ability of RoClean P111 to resist changes in pH during the cleaning process ensures consistent efficacy, regardless of variations in treated water conditions. This is crucial to maintain the effectiveness of the cleaner throughout the entire cleaning process.

Universal compatibility with Polyamide membranes:

RoClean P111 is compatible with polyamide membranes from all manufacturers, making it versatile and applicable to a wide range of reverse osmosis systems, without the risk of damaging the membranes.

NSF/ANSI Standard 60 certification:

RoClean P111 is certified under NSF/ANSI Standard 60, which guarantees its safety for use in drinking water treatment applications. This certification is not common in all membrane cleaners, which highlights the safety and quality of RoClean P111.

Combined use with other Avista™ cleaners:

The ability of RoClean P303 to be used in conjunction with other Avista™ cleaners allows for a more tailored and effective cleaning strategy, leveraging the strengths of different cleaners to address a variety of fouling and contaminants.

Instructions for use

Cleaning

The following is an overview of the cleaning method with RoClean P111. For more information, please refer to our technical bulletin “Cleaning of Spiral Wound Membrane Elements”.

Fill the cleaning tank to the desired volume with RO permeate or deionized water. Heat the solution to the maximum allowable temperature (according to the membrane manufacturer’s instructions), which will significantly increase the cleaning efficiency. Add RoClean P111 in sufficient quantity to form a 2% solution by weight if the soiling is moderate to severe, or a 1% solution by weight if the soiling is light. Recirculate the solution through the cleaning tank to ensure homogeneous mixing.
Run the cleaning solution through each stage of the RO system individually, for a minimum of 60 minutes and at the flow rate recommended by the membrane manufacturer. If that rate is not known, follow the directions provided:

Element diameter (Inches)

10 (2.4)

40 (9.0)
If the membranes are heavily fouled and the recirculated cleaning solution becomes dark or cloudy, remove up to 15% of the solution volume. Heavily soiled items may also benefit from a soaking period (up to 8 hours).
Control the pH of the solution during the cleaning process. If the pH remains within the desired range and the solution does not become cloudy, it can be used to clean the following stages. In the unlikely event that the pH decreases, prepare a new mixture and repeat steps 1 to 4.
Once cleaning is complete, rinse the membranes by passing RO permeate through each vessel under pressure. After that, the system is ready for operation again.
