INTRODUCTION
Avista™ is a global brand of Kurita focused on membrane treatment solutions for reverse osmosis (RO) systems,
microfiltration/ultrafiltration (MF/UF), and multimedia filtration (MMF).
Kurita established the Avista Center of Excellence (CoE), a leadership team located in the United States, Japan,
Malaysia, and the United Kingdom to support each region’s technical centers and global sales network. The Avista CoE
evaluated membrane formulations from both Kurita and Avista Technologies for performance, cost, and dose.
Based on this evaluation, a global line of membrane treatment chemicals was selected to be manufactured
worldwide, covering a full spectrum of foulants and scales. This global line of Avista membrane chemicals includes
Vitec™ antiscalants, RoClean™ membrane cleaners, Kuriverter™ IK biocides, Kuriverter™ AC chlorine scavengers, and
RoQuest™ coagulants.
A regional line of Avista chemicals is available, including AvistaClean™ MF cleaners, RoCide™ biocides, and AntiChlor
chlorine scavengers, among others.
All Avista membrane chemicals are compatibility tested in accordance with key protocols accepted by the industry’s
leading manufacturers. Our globally expanded technical support and laboratory capabilities include Avista™ Advisor™Ci
chemical dosing software, the Avista™ Black Box monitoring device, the Avista™ Membrane Autopsy with Chromatic
Elemental ImagingSM, and Avista™ OSCAR off-site cleaning and restoration.
Avista membrane treatment solutions help to determine the right membrane chemicals to achieve peak system
performance and operator confidence.
VITEC™ 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 RO elements. Vitec antiscalants
are also highly effective at low dose rates. All formulations are NSF approved.

name Avista™VT.
ROCLEAN™ 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 pH ranges, 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
the foulant, suspend the foulant in solution, and disperse the foulant to prevent redeposition. All formulations are NSF approved.

AVISTACLEAN™ MF CLEANERS
The AvistaClean™ MF line is formulated to remove common organic and particulate foulants.
The Kuriverter™ AC Chlorine Scavenger line offers extremely economical options for chlorine removal compared to other methods.
CHLORINE SCAVENGER
Kuriverter AC-427*
• Efficient product to remove free and combined chlorine from RO feedwaters.
• Unique odorless formulation that eliminates the pungent off-gassing of regular bisulfite solutions.
• Certified for use in systems producing potable water.
*Kuriverter AC-427 was previously named AntiChlor 427. This product has been renamed to Kuriverter to create a globally trademarked chlorine scavenger line. There has

The AntiChlor Chlorine Scavenger line offers extremely economical options for chlorine removal compared to other methods.
CHLORINE SCAVENGER
AntiChlor 30
• Injected into RO feedwaters to protect polyamide membranes from permanent damage caused by free and combined chlorine.
• Membrane preservative for long-term storage.
ROQUEST™ COAGULANTS
Avista™ RoQuest™ coagulants are membrane compatible and improve the efficiency of 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.
COAGULANT
RoQuest 3000
• Unique formulation that is a proprietary blend of organic polymers.
• Injected into the feedstream of multimedia or sand filters, where it enhances filter performance by reducing turbidity and color.
• Produces an improved filtrate that reduces RO and nanofiltration (NF) membrane fouling downstream, decreasing cleaning frequencies and increasing system run
times.
• Compatible with polyamide RO membranes and many Avista antiscalants.
COAGULANT COAGULANT
In Malaysia, Philippines, Taiwan, and Thailand, RoQuest is offered under the trade name Avista™RC.
