Membrane Antiscalants
Our Avista Vitec® antiscalants are multicomponent formulations that allow higher reverse osmosis (RO) and nano-filtration (NF) system recovery and reduce cleaning frequency. They inhibit scale while also dispersing colloidal particles to help extend system run times, reduce cleaning frequency and increase the productive life of RO and NF elements. Most are NSF certified for use in systems producing potable drinking water.
Vitec® 3000
Vitec® 3000 is a powerful, broad spectrum, liquid antiscalant and dispersant that is compatible with organic coagulants. It is highly effective at low dose rates and in a wide range of feedwaters and is certified for use in systems producing drinking water.
Vitec® 5100
Vitec® 5100 is a broad spectrum, liquid antiscalant and dispersant that is compatible with organic coagulants, effective at low dose rates and approved for use in systems producing drinking water. It is particularly cost-effective in seawater and municipal applications.
Vitec® 4000
Vitec® 4000 is a liquid antiscalant and dispersant that offers excellent silica scale inhibition and allows increased system recoveries in high silica feedwaters. It is certified for use in systems producing drinking water.
