Frequently Asked Questions What is the difference between low pressure and ultra low pressure RO membranes? Ultra low pressure membranes operate at even lower applied pressure than standard low pressure membranes, making them more suitable for very low TDS feed water and maximum energy savings.

What TDS range is suitable for ultra low pressure membranes? Typically 200-3,000 ppm. For higher salinity water, brackish water membranes are recommended. Will ultra low pressure membranes reduce salt rejection? No. When operated within recommended parameters, salt rejection remains ≥99% under standard test conditions.

How much energy can be saved? Energy savings depend on system design and operating pressure. In large continuous systems, reduced pressure can significantly lower electricity cost per cubic meter. Are these membranes suitable for municipal drinking water projects? Yes.

They are widely used in municipal tap water and surface water treatment systems where energy efficiency is critical. Can ultra low pressure membranes replace existing standard membranes? In many cases, yes. However, system pressure settings and design conditions should be reviewed before replacement.

What pretreatment is required? Feed water should meet: SDI ≤ 5 Turbidity < 1 NTU No free chlorine Proper hardness control Standard pretreatment includes multimedia filtration, activated carbon filtration, and cartridge filtration. What is the expected service life?

With proper pretreatment and operation, membrane lifespan typically ranges from 3-5 years in industrial and municipal systems. Start Reducing Your RO System Energy Cost If you are designing an energy-efficient municipal or industrial RO system, send us your water analysis and system requirements.
