SUEZ DL2540F50 nanofiltration membrane is a high-performance nanofiltration membrane with high salt rejection rate and excellent filtration performance. This nanofiltration membrane can achieve an average desalination rate of 98%, meaning that it can effectively remove divalent ions and ions greater than divalent in water, while the removal of monovalent ions is relatively low. This property makes it very popular in industrial applications, especially where desalination and concentration of organics are required. Below, the blue film water treatment will introduce to you the precautions for its use.
The following points need to be paid attention to during use:
1.Pretreatment: Prior to the use of the SUEZ DL2540F50 nanofiltration membrane, the feed water should be properly pretreated to ensure that the water quality meets the requirements of the membrane. The pretreatment methods include: adding suitable flocculants and pH adjusters, coagulation and sedimentation, activated carbon adsorption, security filtration, etc. The purpose of pretreatment is to remove suspended solids, colloids, microorganisms, organic matter, etc. in the water, reduce the turbidity of the influent water, and reduce membrane pollution.
2.Operating pressure: The working pressure of the nanofiltration membrane is generally about 100psi (690kpa), which should not be too high or too low. Excessive pressure can increase the load on the membrane, leading to membrane fatigue and breakageToo low a pressure can affect membrane flux and desalination. During use, the pressure gauge should be checked regularly to ensure that the system pressure is stable.
3.Operating temperature: The optimal operating temperature of SUEZ DL2540F50 nanofiltration membrane is about 25. Temperatures that are too high or too low can affect membrane flux and desalination. Therefore, during use, attention should be paid to controlling the inlet water temperature to avoid excessive temperature fluctuations.
4.Influent flow: Influent flow is an important factor affecting membrane flux and desalination efficiency. The inlet flow should not be too large or too small, too large will easily lead to membrane fatigue and damage, and too small will affect the treatment efficiency. During use, the inlet flow rate should be adjusted according to the actual situation to ensure the stable operation of the system.
5.Regular cleaning and maintenance: In order to ensure the normal operation and prolongation of the service life of SUEZ DL2540F50 nanofiltration membranes, regular cleaning and maintenance should be carried out.
6.Preservation of the membrane: During transportation and storage, direct sunlight should be avoided to prevent ultraviolet radiation from damaging the membrane. At the same time, the membrane should be kept in a dry, ventilated and dark environment to avoid contact with harmful substances.
7.Safety protection: During the use of SUEZ DL2540F50 nanofiltration membrane, relevant safety regulations should be complied with to ensure the safety of personnel. For example, operators should wear protective clothing, gloves, masks, etc.;Safety warning signs should be set up on site;During the operation of the equipment, it is strictly forbidden for personnel to approach.
