Composite Polyamide Reverse Osmosis (RO) Membranes
DOW™ Reverse Osmosis Membranes Quick Reference Guide – Reverse Osmosis What is reverse osmosis? Reverse osmosis (RO) is the finest level of filtration currently available. RO is a pressure-driven membrane process that separates purified water from a feed stream. RO is so-called because it is the opposite of the natural process known as osmosis. What is the DOW™ FILMTEC™ FT30 membrane... bench-scale reverse osmosis unit for experiments. Several iterations were completed to determine the positive and negative Several iterations were completed to determine the positive and negative aspects of different testing strategies.

acetate membranes, which were the base for the first real world applications of reverse osmosis. North Star, the predecessor of FilmTec, initially used cellulose tri-acetate as separating
- • Reverse osmosis • Electrodialysis The type of filtration used for treatment will depend upon the water quality to be treated and the product water quality goals. For example, if the feed water to be treated is high in inorganics and the product water must meet the Safe Drinking Water Act (SDWA) requirements, the treatment process used must have the capability to remove minerals. If the

- Reverse osmosis (RO) systems are used to produce high-purity water for boiler make-up water, process waters, wastewater reuse, and numerous other applications. In a well-managed sys-tem, operational parameters are mea-sured on a regular basis to assess func-tionality of the machine and determine when RO membrane cleanings are re-quired. The higher the dissolved and suspended solids in the RO
- Reverse Osmosis & Nanofiltration Compared to other filtration technologies that rely on a screen or filter to remove particles, reverse osmosis (RO) and nanofiltration (NF) are pressure-driven separation processes that employs a semi-permeable membrane and the principles of cross-flow filtration.
