Product Advantage:
1.The world's leading mature technology
2.Non-standard customized advanced manufacturing equipment
3.High throughput:Optimize raw materials, adjust casting film and coating process, improve permeability.
4.High desalination:The formulation was optimized to regulate the crosslinking degree of polyamine and the morphology and structure of the functional layer to improve the selective permeability.
5.Resistance to pollution:Through special additives and post-treatment process, the separation membrane can effectively reduce the adsorption and retention of pollutants and improve the anti-pollution ability.
6.Stability:The excellent chemical stability of each material ensures the solvent resistance and acid and alkali resistance of the separation film, improves the service life of the separation film and expands its application range.
7.Ultra-thin functional layers achieve performance leadership
8.Multi-layer composite structure ensures stable quality
Operation Notes：
1.Before installation please don't unpack the membrane elements, store in a dry and ventilated place away from light with temperature between 10 and 35C. Elements should be handled with care when in transit.
2.Prohibit brutal installation such as metal hammer beating, follow starting procedure strictly in order to prevent membrane damage caused by excessive impact.
3.Carry out instrument calibration, membrane pretreatment and system inspection before system startup and membrane elements loading.
4.Try to avoid hydraulic impact or cross-current fluctuation on the spiral-wound membrane elements and start system gradually.
5.Monitor water quality of pretreatment and discharge water in the first hour of the first use.
6.If system shutdown short-term (within 15 days), please close valve of the system to keep membrane elements moist and wash regularly.
7.Don't produce backpressure in any case.
8.Maximum allowable pressure drop of membrane shell is 50psi (3.4bar).
9.If system shutdown for a long time, please soak membrane elements in the preservative solution to prevent bacterial growth.
10.Please ensure chemicals and lubricants don't affect membrane elements adversely in use.
11.If membrane system performance drops by 10% under standard conditions, or membrane fouling and scaling occur, please rinse membrane elements according to regulation process immediately.
12.The manufacturer won't provide warranty service, if the operating requirements and conditions aren't complied with.
