Low pressure RO element Dupont LC LE PRO-4040

Low pressure RO element Dupont LC LE PRO-4040

Introduction of Low pressure RO element Dupont LC LE PRO-4040:

FilmTec™ LC LE PRO-4040 Elements deliver high quality water at low pressure at harsh water conditions, using DuPont’s innovative, proprietary technology for low energy commercial applications. DuPont’s fully automated element production enables the most consistent products in the industry that minimizes the total cost of ownership of water treatment systems.

FilmTec™ Brackish Water Reverse Osmosis 4″ Elements can separate salts from water and are produced with an automated fabrication process that ensures precision, consistency, and reliability. They are ideal for use in medium-sized water treatment system that produce less than approximately 10 gpm (2300 L/h) of permeate. Our RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.

Outstanding advantages of Low pressure RO element Dupont LC LE PRO-4040:

• High rejection results in excellent water quality
• Low energy usage reduces power consumption and costs durable with good cleanability for long element life
• Outstanding quality, completely eliminating toxic organic and inorganic impurities and microorganisms harmful to health
• Widely used in household bottled water production lines or in food and beverage processing plants and industrial chemical plants.
• Easily retrofit existing systems
• The membrane has high permeability.
• Membranes with a rigid outer shell are recommended for systems with multi-diaphragm shells containing three or more membranes because they are designed to withstand higher pressure drops.

Factors that need to be collected to choose the right type of RO membrane:

1. What is the input water? (Sea water, brackish water, river water, well water, city water supply water, wastewater (with or without UF pretreatment), level 1 RO water, level 2 RO water)
2. Capacity needed to treat water per day, per hour?
3. Main indicators of raw water quality: TDS, pH, temperature, salinity, hardness, silica…
4. Desired water output quality? (used for what, eating or living or production?)
5. Installation area to be able to choose membrane housing length configuration

Select the permeate flow design capacity for each 4inch RO membrane for different types of input water:

1. RO water: SDI (Silt Density Index) = 1, design flow 34LPH for 1m2 = 244,8L/H
2. Brackish water is well water: SDI (Silt Density Index) = 3, design flow 25-27LPH = 180-194,4L/H
3. Brackish water is surface water: SDI (Silt Density Index) = 5, design flow 18-21LPH = 129,6-151,2L/H
4. Sea water: SDI (Silt Density Index) = 5, design flow 12-13LPH = 86,4-93,6L/H
5. Wastewater with UF pretreatment: SDI (Silt Density Index) = 3, design flow 18LPH = 129,6L/H
6. Wastewater Without UF pretreatment: SDI (Silt Density Index) = 5, design flow 15LPH = 108L/H
