International brand dossier
Kurita is a Japanese industrial water-treatment group founded in 1949, originally around boiler water-treatment chemicals, and now one of the major global suppliers of water-treatment equipment, chemistries, and services.
Avista sits inside this operating logic as a membrane-treatment chemistry and service platform for RO/NF/MF/UF systems.Avista's position in water treatment chemicals is defined by product families such as Antiscalant, Coagulants & Flocculants, Biocides and Liquid & Powder cleaners.
The portfolio is best understood inside RO/NF membrane operation, cooling and boiler water programs, pretreatment, cleaning, and plant reliability work, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.Representative series on this page include Vitec® 1000, Vitec® 1100 and Vitec® 1200.Engineers should first compare target foulants, chemical function, dosage window, compatibility, and field support.

Product range and selection
This section answers two questions: which main product families Avista offers, and which parameters to compare before choosing a specific model.
The main families shown on this page are Antiscalant, Coagulants & Flocculants, Biocides, and Liquid & Powder cleaners. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.
After choosing a product family, compare water analysis, dose range, compatibility, and cleaning objective. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.
