Reverse osmosis (RO) is a pressure-driven separation process that employs a semipermeable membrane and the principles of crossflow filtration. Reverse osmosis water treatment provides the finest level of filtration. RO membranes act as a barrier to all salts and inorganic molecules, as well as organic molecules with a molecular weight greater than approximately 100.
Brackish Water
Brackish water elements are an industry standard for commercial and industrial water treatment systems
Minimal liquid discharge (MLD) elements minimize OPEX/CAPEX costs by maximizing water recovery while reducing the amount of energy required to operate.
Nanofiltration (NF) is a membrane liquid-separation technology sharing many characteristics with reverse osmosis (RO). Unlike RO, which has high rejection of virtually all dissolved solutes, NF provides high rejection of multivalent ions, such as calcium, and low rejection of monovalent ions, such as chloride.
Seawater elements are the standard for systems operating at low to medium levels of salinity and temperature, as well as for brackish water with relatively high salinity. The element’s flowrate is significantly above flowrates of any other SWRO element currently available in the market. Filmtec has the only dry tested SWROs on the market.
Tapwater home drinking-water elements are precision fabricated and thoroughly tested to ensure that they provide predictable, trouble-free operation and consistent high performance. They meet a wide range of water volume requirements, from 24 gallons per day to 800 gallons per day.
Nanofiltration Produces Sparkling Clean Water for Swedish Resort Community
Lofsdalen, Sweden, had an outdated water treatment process complicated by variable water quality from an unreliable source. Using FilmTec™ NF255-400 membranes, the town could pull water from Lake Lofssjön, remove the contaminants, and provide sparking clean drinking water to the town residents and tourists.
FilmTec™ NF270-400 Element Helps National Park Service Improve Water Quality
The Denver Service Center of the U.S. National Parks struggled to treat tricky water that needed to meet EPA secondary Standards. Check out the full article to see the raw water constitutes, met requirements, and reduced operational cost.
FilmTec™ BW30-400 Elements: Municipal Application on Well Water
New thin-film composite FilmTec™ BW30-400 elements were installed in an existing FilmTec™ RO treatment system, replacing old but not expired elements with the latest, higher-performing, technology. The new membranes improved the overall capacity for the Island Water Association (IWA) on Sanibel Island, which allowed for the cancelation of a major plant expansion.
