Avista Membrane Technologies
Description
Kurita’s Avista Membrane Treatment Solutions global product line are specialty products and services that support reverse osmosis (RO), nanofiltration
(NF), and micro/ultrafiltration (MF/UF) membrane system optimization, providing operational savings and positive environmental impact. Our comprehensive approach determines the best chemical treatment program to maximize the reliability and productivity of membrane systems while simultaneously reducing environmental and operational costs.
Our list of membrane solutions includes software, antiscalants, cleaners, membrane autopsy service, off-site cleaning, biofouling solutions, chlorine scavenger, and coagulants.
Avista Advisor CI online, our industry-leading proprietary chemical projection software, uses cutting-edge complex ion calculations to accurately determine the types and quantities of scale that are at risk of precipitating. The software provides the dose rate for the appropriate antiscalant and allows system designers to select products and define dose rates or batch quantities for coagulants, biocides, dechlorination, and membrane cleaning products. My Kurita Portal allows operators, site managers and our membrane experts to share, normalize, trend and review all system data allowing for fast identification of operational issues, measurement of effect of optimization actions, and more.
The Vitec™ antiscalants inhibit a comprehensive range of scales and provide colloidal particle dispersion allowing high RO system recovery rates to minimize effluent discharge.
The RoClean™ cleaners provide effective solutions formulated to quickly remove the complex blends of foulants and scalants that are deposited in RO and NF membrane systems. RoClean cleaners are highly buffered to maintain safe pH levels for membranes and those handling the solutions.
Kurita offers a membrane autopsy service, which provides a detailed analysis of a membrane’s condition. Chromatic Elemental Imaging (CEI) is used for accurate, high-resolution imaging that identifies the exact location and concentration of elements in a foulant sample.
Kurita’s Off-site Cleaning and Restoration (OSCAR) establishes the condition of every membrane in your system with our factory tests and recover membranes to their maximum potential using optimized membrane cleaning facilities. All membranes are returned with a performance test report and packaged safely for storage until required for operation.
Our biofouling solutions have the power to penetrate and disrupt existing biofilms while featuring significantly lower aquatic toxicity than traditional oxidizing and non-oxidizing biocides.
Our Chlorine Scavenger line offers cost effective options for chlorine removal compared to other methods.
RoQuest™ coagulants are membrane compatible an improve the efficiency of multi-media filtration (MMF) equipment. Studies show that MMF equipment without coagulant addition will only remove approximately 35% to 50% of particulates. A nominal dosage of RoQuest coagulant may remove over 97% of particulates on MMF equipment.
Our products are compatibility tested with the major RO and NF membrane manufacturers and manufactured globally under strict quality controls for reliability and to uphold the conditions of the many drinking water and other industry sector registrations that are maintained.
