SUEZ DL8040F30 nanofiltration membrane is an industrial-grade nanofiltration membrane element characterized by high desalination rate and molecular weight cut-off, which is suitable for a variety of industrial water treatment processes. The COD removal rate in biochemical effluent can reach 80-90%, which is suitable for the treatment of a variety of pH environments and chemicals. When using nanofiltration membranes, operating and maintenance guidelines should be followed to ensure the performance and longevity of the membrane elements. Below, the blue film water treatment will introduce to you the cleaning of its serious fouling.
Cleaning methods taken for severe fouling
When the SUEZ DL8040F30 nanofiltration membrane is severely fouled, the following cleaning methods can be taken:
1.Physical cleaning: The membrane surface is cleaned using a high-pressure water gun or brush to remove the dirt layer. During the cleaning process, it is necessary to pay attention to the moderate force to avoid damage to the membrane.
2.Chemical cleaning: The membrane surface is cleaned with a special chemical cleaning agent to dissolve and remove dirt. When choosing a cleaning chemist, make sure it has good compatibility with SUEZ DL8040F30 nanofiltration membrane material.
3.Alternate cleaning: Physical cleaning and chemical cleaning can be alternated, with physical cleaning followed by chemical cleaning to achieve better cleaning results.
4.Regular cleaning: In order to prevent fouling on the membrane surface, the membrane should be cleaned regularly to keep the membrane surface clean. The cleaning cycle can be adjusted appropriately according to the actual operation conditions and water quality conditions.
Precautions for cleaning
When cleaning SUEZ DL8040F30 nanofiltration membranes, the following points should be noted:
1.Selection of cleaning agent: Ensure that the cleaning agent has good compatibility with the membrane material to avoid damage to the membrane.
2.Cleaning pressure: During physical cleaning, the cleaning pressure should be controlled to avoid damage to the membrane. When chemical cleaning, it is necessary to operate according to the cleaning pressure recommended by the manufacturer.
3.Cleaning time: The chemical cleaning time should not be too long, so as not to cause damage to the membrane. In general, the chemical cleaning time should be controlled within 30 minutes.
4.Cleaning frequency: The cleaning frequency should be adjusted appropriately according to the actual operation and water quality conditions to keep the membrane surface clean.
During operation, the SUEZ DL8040F30 nanofiltration membrane may experience severe fouling. Mastering the correct cleaning method can effectively remove dirt from the surface of the membrane and restore the performance of the membrane. In the actual operation process, it is necessary to reasonably select the cleaning method according to the actual situation and follow the precautions to ensure the safe and stable operation of the membrane equipment.
