MANGANESE FOULING
VITECTM ANTISCALANTS
The Avista™ Vitec™ antiscalant line inhibits scale while also dispersing colloidal particles. The inhibition and dispersant properties of Vitec™ products help extend system run times, reduce cleaning frequency, and increase the productive life of of reverse osmosis (RO) elements. They are also highly effective at low dose rates. All formulations are NSF approved and UK Drinking Water Inspectorate (DWI) approved for specific products.

RoCLEANTM CLEANERS
Avista™ RoClean™ cleaners provide efficient and cost-effective removal of many different foulants and scales. All products are low foaming and membrane compatible. These products come in a variety of pHs and the line contains a liquid and powder product for most foulants and scales. RoClean™ cleaners are highly buffered and contain a unique blend of ingredients that wet and break up foulant, suspend the foulant in solution and disperse the foulant to prevent redeposition. All formulations are NSF approved and/or EN12124 compliant for drinking water treatment chemicals for specific products.

RoQUESTTM COAGULANTS
Avista™ RoQuest™ coagulants are membrane compatible and improve the efficiency of multimedia filtration (MMF) equipment. Studies show that MMF equipment without coagulant addition will remove approximately 35% – 50% of particulates. A nominal dosage of a RoQuest™ coagulant may allow MMF equipment to remove over 97% of particulates.
PRODUCT RANGE
AVISTACLEANTM MF CLEANERS
The Avista™ MF Cleaner line is formulated to remove foulants and can replace generic cleaners.
BIOCIDES
Our biocides may be applied intermittently via continuous injection or as a periodic addition to your clean-in-place (CIP) system.
PRODUCT RANGE
CHLORINE SCAVENGERS
Membranes can last for days or years depending on the care they receive. Chlorine in feedwater can permanently damage membranes, requiring them to be replaced. Unique Avista™ formulations remove free and combined chlorine from RO system feedwaters to protect membranes from oxidation damage. These chlorine scavengers are certified for use in systems producing potable water are odorless and stabilized to prevent off-gassing, making it ideal for indoor installation.
