AvistaClean® MF1000
MF/UF Alkaline Membrane Cleaner - Powder
Data Sheet
AvistaClean® MF1000 is a proprietary cleaner used to remove organic and particulate foulants that coat and plug microfiltration (MF) and ultrafiltration (UF) membrane surfaces and pores.
This product is a one-step cleaning process. However, it can be used in conjunction with AvistaClean MF3000 when the membrane foulant contains calcium carbonate and/or metals.
This product has proven compatible with the MF/UF modules offered by the major membrane manufactures.
Performance:
AvistaClean® MF1000 offers an array of performance benefits:
- Highly effective powder cleaner for the removal of organic and colloidal foulants.
- Designed specifically for both microfiltration (MF) and ultra filtration (UF) membrane systems.
- Superior cleaning results, especially when compared to generics which were not designed for this specialty application.
- May be used in conjunction with other AvistaClean formulations.
- Highly buffered to resist pH changes during the cleaning process.
- Temperature compensated to maintain optimum pH over a wide temperature range.
Use Instructions:
Below are general guidelines for cleaning MF/UF systems. Please consult the system manufacturer for detailed instructions specifically for your MF/UF system.
- Fill the cleaning tank with reverse osmosis (RO) permeate or demineralized water. If neither of these water sources is available, softened water may be used. Do not dissolve cleaners in hard water. The water volume required for cleaning is generally equal to the total volume of the system, hoses, and cartridge filters.
- Heat the water to the maximum temperature allowed by the MF/UF module manufacturer, usually in the range of 104°F to 122°F (40°C to 50°C).
- When the water is hot, add the AvistaClean MF1000 to the tank. Thoroughly dissolve the cleaner by either recirculating water through the tank or by using a mechanical mixer. Add sufficient AvistaClean MF1000 to create a 2% wt/wt solution if the fouling is moderate/severe or 1% if the fouling is mild.
- With the filtrate valve shut, recirculate the cleaner through the modules in the feed direction for 30 minutes (for tubular designs only). After 30 minutes, reverse the flow direction, from the exit to the feed, for an additional 30 minutes.
- Modules designed to be back flushed can be back flushed with cleaning solution in the filtrate to feed direction for 15 minutes.
- Flush the system with MF/UF filtrate.
