Box-type Ultrafiltration System Manufacturers

What are the common faults and troubleshooting methods of box-type ultrafiltration systems?
1. Clogging of the filter membrane: If the surface area of the filter membrane is too large or the pore size of the filter membrane is too small, it will easily become clogged. The treatment method is to clean the filter membrane or replace it with a new one.
2. Leakage: The pipes or seals in the ultrafiltration device are leaking. The treatment method is to check the leak point and repair or replace the leaking parts.
3. Excessive water inlet pressure: The ultrafiltration device operates outside the design pressure range, causing device abnormalities. The solution is to check the pressure control device of the water inlet system and adjust the pressure to an appropriate range.
4. Changes in water quality: The concentration of suspended solids and colloidal particles in the incoming water of the ultrafiltration device is too high, causing the filter membrane to be clogged or damaged. The treatment method is to pretreat the incoming water, such as adding precipitant, filtering, adjusting pH value, etc.
5. The raw water inlet volume is low or the pressure is insufficient: It may be that the pretreatment part of the ultrafiltration equipment has failed, the water inlet pressure of the ultrafiltration equipment is insufficient, or the equipment valve is faulty. The solution is to unclog or replace the parts in the problem area.
6. The water production of the equipment drops to 80% of the normal amount: It may be that the ultrafiltration membrane of the equipment is contaminated, the quality of the raw water has deteriorated or the temperature has dropped, which is inconsistent with the initial design of the equipment, the water supply is insufficient, or the equipment is improperly maintained. Failure, etc. The solution is to clean the equipment and add medicine and sterilization to solve the pollution; re-analyze the water quality of the raw water or increase the water temperature, reset the equipment and add or replace the pre-embedded device; consult the after-sales service for correct maintenance methods to avoid incorrect operations.
7. The quality of the effluent water has deteriorated or the interception capacity has deteriorated: it may be due to secondary pollution of the water, deterioration of the raw water quality, or incorrect selection of the filtration accuracy of the ultrafiltration equipment. The solution is to sterilize and clean the parts where secondary pollution may occur; reanalyze the quality of the raw water, reset the equipment and add or replace the pretreatment device; and reset the membrane components of the equipment.
8. The pressure variable value suddenly rises: it may be that the pneumatic butterfly valve is faulty. The solution is to test the pneumatic butterfly valve and check the circuit.
9. The backwash pump does not start normally: it may be that the water level in the water tank or the produced water tank of the ultrafiltration equipment exceeds the rated height, and the water pressure in the backwash inlet part is too high. The elimination method is to wait for the water levels in the two water tanks to drop before starting; adjust the backwash inlet butterfly valve until the inlet water pressure is less than

What fields are box-type ultrafiltration systems suitable for?
1. Drinking water treatment: Ultrafiltration technology can remove impurities, bacteria, viruses, and other harmful substances in the water, providing clean and safe drinking water. Suitable for homes, public places, industry, and other fields.
2. Food and beverage processing: Ultrafiltration systems can be used to produce high-quality food and beverages, such as alcohol, juice, dairy products, etc. By removing impurities and microorganisms, the quality and taste of the product are guaranteed.
3. Medical treatment and pharmaceuticals: Ultrafiltration technology is used for the preparation of high-purity medicinal liquids and the disinfection and purification of medical water. Impurities and microorganisms in drugs can be removed to ensure the safety and effectiveness of drugs.
4. Industrial water treatment: Ultrafiltration systems are widely used in industrial water treatment fields, such as cooling water treatment, boiler water softening, industrial wastewater treatment, etc. It can effectively remove impurities and harmful substances in water and improve water quality.
5. Seawater desalination: Ultrafiltration technology is used for seawater desalination to prepare fresh water by removing salt and other impurities in seawater. This is of great significance for areas lacking freshwater resources.
6. Agricultural irrigation: Ultrafiltration systems are used to treat agricultural irrigation water, remove impurities and harmful substances in the water, and ensure the quality and safety of irrigation water.
