Detailed description
(1) Product Features
It features high flux, high desalination rate, and long service life, and is designed to meet the national Class I water‑efficiency standards. Under high recovery conditions, it exhibits excellent anti‑fouling performance and is well suited for use in water with high hardness. Leveraging advanced membrane technology and a fully automated production line, the product’s reliability and stability are reliably ensured.
(2) Model and Performance Specifications
| Product Name | Target component water production (G) | Desalination rate of the target component (%) |
| ULP | 75, 200, 400, 600 | ≥90 |
| ULP-Plus | 800, 1000 | ≥90 |
| ULP-Max | 1200 | ≥90 |
(a) Test conditions: 251 ppm CaCl₂, 210.5 ppm MgSO₄, 79 ppm NaCl, 265.3 ppm NaHCO₃, trace NaClO (per the national standard for new water efficiency), 100 psi (0.69 MPa), pH = 7.0 ± 0.1, temperature 25 ± 0.5°C, recovery rate 50–70%. The dimensions and effective area of the membrane elements may be adjusted based on actual operating conditions.
(b) All permeate samples were collected after 30 minutes of stable operation.
(c) Each roll of diaphragm is individually packaged and sealed in black plastic film. The standard length of each roll is 300 m or more, though this may vary under certain circumstances.
(d) The membrane performance parameters listed in the table above may vary within a certain range depending on water quality conditions and operating conditions. If you are uncertain about product selection or unable to predict product performance, please contact us first to arrange membrane selection and system matching.
(3) Storage Conditions and Warranty Period
Storage conditions: Protect from sunlight and ultraviolet radiation; store at 10–30°C with relative humidity below 50%.
Warranty Period: ULP products are covered by a 6-month warranty from the date of manufacture; it is recommended to use them within 3 months of receipt. ULP-Plus and ULP-Max products are covered by a 2-month warranty from the date of manufacture; it is recommended to use them within 1 month of receipt.
