FAQ
Q: What are the key differences between the 8040 low-pressure reverse osmosis membrane and standard membranes?
A:Lower Operating Pressure: For the same water production volume, low-pressure membranes typically require an inlet pressure that is 20%–30% lower than that of standard membranes (e.g., while standard membranes require 1.5–2.0 MPa, low-pressure membranes require only 1.0–1.5 MPa).
Significant Energy-Saving Advantages: They reduce the energy consumption of high-pressure pumps, making them ideal for large-scale water treatment systems (such as reclaimed water reuse and boiler feedwater applications).
Comparable Desalination Rates: Low-pressure membranes still achieve a stable desalination rate of over 99.3%
Applicable Scenarios: Projects involving feed water with low salinity levels (such as tap water or surface water) and those where operating electricity costs are a critical consideration.
Q: Do low-pressure membranes impose stricter requirements on feed water quality?
A: The SDI (Silt Density Index) must still remain below 5, with some applications requiring it to be below 3 (consistent with standard membranes).
Tolerance levels for residual chlorine, temperature, and pH are essentially the same as those for standard membranes (pH range: 2–11; residual chlorine: <0.1 mg/L).
Low-pressure membranes are more susceptible to fouling by organic matter and microorganisms, as their surface charge and roughness may have been optimized for low-pressure operation; consequently, enhanced pretreatment is required.
Recommendation: Install a guard filter (filtration rating ≤5 μm) and regularly monitor the ORP (Oxidation-Reduction Potential).
Q: Does the cleaning cycle for low-pressure membranes differ from that of standard membranes?
A: The cleaning frequency is higher (approximately once every 1–3 months, whereas standard membranes can go 3–6 months), as the surface of low-pressure membranes is more prone to adsorbing low-molecular-weight organic substances.
Recommended Cleaning Methods:
Acidic cleaning (pH 2–3, using citric acid or HCl) to remove inorganic scaling.
Alkaline cleaning (pH 11–12, using NaOH + EDTA) to remove organic matter and microorganisms.
Note: Avoid using strong oxidizing agents (such as sodium hypochlorite), as they will damage the polyamide layer of the membrane.
