Membrane Cleaners
Our AvistaClean® and RoClean liquid and powder formulations are proprietary membrane cleaners that provide efficient and cost-effective removal of all types of membrane foulants. They’re powerful against organic and inorganic foulants and compatible with all membranes. Several cleaners are classified as Green Chemicals to help meet strict environmental discharge limits, and are the highest performing green cleaners in the industry. Most are NSF certified for use in drinking water potable systems.
POWDER MEMBRANE CLEANERS
AvistaClean® P611 Green
AvistaClean® P611 powder is free of phosphate and EDTA. It dissolves organic foulants such as humic acids, fatty acids, siloxane compounds, fungicides, pesticides and pharmaceutical compound and is highly buffered to resist pH changes during the cleaning.
RoClean P111
RoClean P111 powder is a multicomponent, high pH buffered cleaner formulated to remove biological fouling in the presence of hydrophobic and hydrophilic organics and particles, such as clay, from membranes.
RoClean P112
RoClean P112 powder is a multicomponent, high pH buffered cleaner specifically formulated to safely remove silica scale from membranes.
RoClean P303
RoClean P303 powder is a multicomponent, low pH buffered cleaner formulated to remove metal foulants and calcium carbonate from membranes.
RoClean P703 and P903
RoClean P703 and P903 powders are multicomponent, low pH buffered cleaners formulated to remove metal foulants such as iron, manganese and aluminum from membranes.
RoClean P911
RoClean P911 powder is a multicomponent, high pH buffered cleaner formulated to remove particularly high levels of organics, including humic and fulvic acids.
LIQUID MEMBRANE CLEANERS
AvistaClean® L011
AvistaClean® L011 liquid is a multicomponent, high pH buffered cleaner formulated to remove oils and grease from membranes.
RoClean L211
RoClean L211 liquid is a multicomponent, high pH buffered, low-foaming cleaner formulated to remove colloidal silica, clays, organic color and bacterial slime from membranes.
RoClean L212 Green
RoClean L212 liquid is a multicomponent, high pH buffered cleaner formulated to remove clay and metal oxides from membranes.
RoClean L403
RoClean L403 liquid is a multicomponent, low pH cleaner formulated to remove metal foulants and calcium carbonate scale from membranes.
RoClean L811
RoClean L811 liquid is a multicomponent, high pH buffered cleaner formulated to remove sulfate scales including barium, strontium and calcium sulfate from membranes.
UF / MICRO FILTRATION MEMBRANE CLEANERS
Our Avista micro-filtration (MF) / ultra-filtration (UF) specialty formulations may be applied in place of generic cleaners or as a periodic recovery cleaner between cleanings with generics. The AvistaClean MF line is formulated to remove common foulants and offer superior results compared to generics. To assist you in identifying site-specific foulants, we offer the MF / UF Cleaning Study and the MF / UF Membrane Autopsy, which includes Chromatic Elemental Imaging, a new technology to identify the location and relative concentration of elements in a membrane fiber sample.
AvistaClean® MF 1000
AvistaClean® MF 1000 powder is a proprietary, one-step cleaner used to remove foulants from MF and UF membrane surfaces and pores.
AvistaClean® MF 1000A
AvistaClean® MF 1000A powder is a synergistic cleaner blend formulated to remove organic and particulate foulants from chlorine tolerant MF and UF membrane surfaces and pores.
AvistaClean® MF 3000
AvistaClean® MF 3000 powder is a low pH, proprietary cleaner that removes calcium carbonate and metal foulants from MF and UF membrane surfaces and pores.
