Analysis of Operation Faults of Ultrafiltration Equipment

Ultrafiltration equipment is a separation technology that utilizes pressurized membranes. It refers to the process of passing small molecule substances through a specially designed membrane with a fixed pore size under a constant pressure, while large molecule substances are blocked and left on the other side of the membrane, thus purifying water quality. Effectively remove particles, colloids, bacteria, heat sources, and organic matter from water, with a filtration accuracy of 0 01 microns. At present, ultrafiltration equipment is widely used in reverse osmosis equipment pretreatment, reclaimed water reuse in sewage treatment, large and medium-sized drinking water plants, and so on.

So what problems may arise during use? How should we solve it?

1. What is the reason for the high pressure difference on both sides of the ultrafiltration membrane? How should we solve it?

1) The membrane components may be contaminated;

Solution: Eliminate the system one by one, investigate the reasons for possible contamination of the SEP membrane, repeatedly clarify, adjust new flushing parameters, and thoroughly clean the SEP membrane. If necessary, replace the membrane components.

2) Excessive water production flow;

Solution: Adjust and control the water mixing flow rate according to the specific operation to avoid excessive membrane pressure difference caused by excessive water production flow rate.

3) ; The inlet water temperature is too low;

Solution: Heat the inlet water temperature appropriately, especially in winter, and take anti freezing measures. Take insulation measures for equipment and pipelines.

2. What is the situation where the water production of the entire equipment has significantly decreased?

1) The ultrafiltration membrane is polluted or blocked;

Solution: Investigate the cause of contamination of the ultrafiltration membrane components, rinse them, and replace the membrane components if necessary.

2) The opening of the valve is not set reasonably;

Solution: Check the status of the entire system's valves, check all valves that should be opened, ensure that all valves are fully open, and ensure that the opening of each valve is within a reasonable range.

3) There is a problem with the flow meter, it may be broken;

Solution: Check all flow meters for any problems, malfunctions, or other issues, and promptly resolve or replace the flow meters.

3. What is the reason for the substandard water quality of the produced water?

1) The inlet water quality is too poor, exceeding the minimum required range

Solution: Check the water quality of the incoming water, mainly detecting the COD, total iron and manganese, and whether the turbidity of the incoming water is within the allowable range. If it is not within the allowable range, pre-treatment equipment needs to be added in front of the ultrafiltration equipment.

2) The ultrafiltration membrane component may be damaged and unable to meet the filtration requirements;

Solution: Find out the areas and reasons in the system where the ultrafiltration membrane may be damaged. Before replacing the membrane components, first address the reasons for the damage to the membrane components.
