Outstanding advantages of Low pressure RO element Dupont LC LE 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.

• Maximum Pressure Drop: 15 psig (1.0 bar)
• pH Range, Continuous Operation: 2 – 11
• pH Range, Short-Term Cleaning: 1 – 13
• Maximum Feed Silt Density Index: SDI = 5
• Free Chlorine Tolerance <0.1 ppm

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
