Vitec® | ANTISCALANTS

Vitec antiscalants and dispersants are multicomponent formulations that allow higher RO system recovery rates and reduce cleaning frequency.

Our Vitec antiscalants inhibit 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. The Vitec 8000 series antiscalants are part of our Green Chemicals line, specially formulated for sites with discharge restrictions.

AntiChlor | CHLORINE SCAVENGER

AntiChlor formulations remove free and combined chlorine from RO system feedwaters to protect membranes from oxidation damage. 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. AntiChlor liquid is an extremely economical option for chlorine removal compared to other methods. It’s offered in two formulations and both are certified for use in systems producing potable water. To make membrane care even simpler, our Avista Advisor software calculates dose and consumption rates of AntiChlor products for your convenience.

RoCide® | BIOCIDES

RoCide is a non-oxidizing, membrane compatible biocide to reduce biological fouling in membrane systems. RoCide biocides are broad spectrum formulations that combat contaminants such as bacteria, fungi and algae. They are compatible with all membranes and can be used with various Avista cleaners. Our biocides may be applied intermittently, via continuous injection or as a periodic addition to your clean-in-place (CIP) system.

RO CARE PRODUCTSAvista takes a customized approach to optimizing your RO system, using a combination of high performance products, lab services and analytical tools.

AvistaClean® and RoClean | CLEANERS

Our AvistaClean and RoClean formulations are proprietary, membrane compatible cleaners that provide efficient and cost-effective removal of all common foulants. AvistaClean and RoClean products come in a variety of pH ranges and include liquids or powders. Many are certified for use in potable water systems. They’re powerful against organic and inorganic foulants and compatible with all membranes. Several cleaners are classified as Green Chemicals to help Avista customers meet strict environmental discharge limits. The cleaners in our Green Chemicals line are the highest performing green cleaners in the industry.

SafeGuard | MEMBRANE STORAGE CHEMISTRY

SafeGuard chemicals are designed to minimize bacterial growth during membrane storage or system shutdown and are safer than other commonly used chemicals. SafeGuard liquid protects elements installed in pressure vessels or removed for storage. It’s compatible with pressure vessels, piping and all related materials of construction commonly used in RO systems. SafeGuard lets you avoid the problems commonly associated with sodium bisulfite and metabisulfite solutions. Its neutral pH means no issues with low pH preservatives.

Phoenix | MEMBRANE SIZING AGENT

Phoenix membrane sizing agents improve salt rejection and extend the useful life of partially oxidized or damaged RO polyamide membranes. Phoenix restores performance by forming a coating on the membrane surface to enhance salt rejection properties. Applying Phoenix powder takes 30-60 minutes. Because Phoenix is applied on-line, there’s no interruption in plant productivity.
