Filmtec 50gpd RO Membrane Dow Part # TW30-1812-50

Overview
FILMTEC 50gpd RO Membrane by Dow Part # TW30-1812-50HR (New Part Number)
Dow's next generation elements have been precisely designed and will replace existing DOW FILMTEC™ residential RO elements. Performance specifications are identical for both DOW FILMTEC existing and next generation of products.
Product improvements and enhanced features:
- Dow has completely redesigned all standard DOW FILMTEC residential RO elements using optimized materials of construction and our industry-leading product development capabilities. The next generation design offers equivalent or superior overall performance compared to existing DOW FILMTEC standard products. Elements with a flow rate equal to or greater than 50 GPD now have a two leaf design improving element efficiency and water quality while maintaining trouble-free operation. The new element is compatible with all element housings that have previously used DOW FILMTEC residential elements.
- An innovative brine seal design, patent pending, will replace the current taped u-cup brine seal. Exhaustive studies demonstrated that installation and removal of the element into and out of the housing are comparable with current taped brine seal design.
- Reliable seal: when residential RO systems are not in use, the brine seal is used to direct rinse water through the element scroll to improve pure water quality and reduce scale formation. Taped on, u-cup brine seals depend on flow direction and pressure drop through the element scroll to "inflate" them and form a tight seal. In most residential systems, the rinse water flow rate through the scroll is limited by a flow restricted to conserve water. If it is too low, the pressure drop required to inflate the u-cup falls below one psi which does not always create a reliable seal.
- Dow's innovative brine seal design forms a press-fit between the element and the housing that does not need on pressure drop through the scroll to make a reliable seal. If a pressure spike occurs, the innovative brine seal also has another benefit. During the initial residential RO system charging, feed water pressure spikes can occur across an element until water completely fills the element housing. Pressure spikes can cause taped u-cup seals to slip and deform creating a permanent leak. Dow's new brine seal is designed to relieve then reseal should a pressure spike occur.
Genuine Filmtec Membranes:
- Filmtec is the most copied and knocked-off membrane in the world, to combat this they have added multiple anti-counterfeiting features including a water drop hologram on the label, product code, and model description, a unique imprinted product serial number
Quality Assurance:
- Enhanced quality control throughout the entire production process; eleven different quality checks monitor all critical dimensions and product characteristics. 100% of all DOW FILMTEC™ residential elements must pass an element integrity test before packaging to ensure our customers receive defect-free products.
Notes:
- Flow Control Valves/Restrictors: Often the small openings or tubes in a flow control valve can become plugged, it is advisable to replace this valve when replacing your membrane. A standard matching flow control valve to this 50 gpd rated membrane is a 350ml flow restrictor part # FR500EZ. Though may see slightly lower rates ones when the water is very clean and lower TDS levels or higher ones when the incoming water is quite dirty or very high TDS levels.
- TFC means these are thin film composite membranes that are not chlorine tolerant, one must have some type of carbon filter before the membrane when chlorine is present in the water.
