Install multimedia and security filters at the inlet to trap sand, silt, and fibrous impurities; perform air purging and online chemical cleaning on a regular basis; and control the levels of suspended solids and residual chlorine in the feedwater. Proper pretreatment can reduce membrane clogging by 70% and significantly extend cleaning intervals.
To request a quote for an ultrafiltration water system, please provide the following six categories of key information:
- Average daily/hourly water production and daily operating hours;
- A complete raw water quality test report (turbidity, COD, suspended solids content, pH range, water temperature, and whether the water contains characteristic contaminants such as oils, microorganisms, high concentrations of salts, or oxidizing substances);
- Preferred membrane material and type;
- Requirements for automation and cleaning systems;
- Installation site and power supply conditions;
- Whether transportation, installation, warranty, and consumables are included.
Yes, an ultrafiltration water system is required. When the raw water has high colloidal content and unstable SDI, an ultrafiltration water system can consistently reduce the SDI and protect the reverse osmosis membranes.
An ultrafiltration water system primarily removes suspended solids, colloids, and macromolecules through membrane pore size screening.
A reverse osmosis water filter primarily removes dissolved salts, ions, and small-molecule contaminants.
The two systems have different treatment objectives; in many industrial water treatment projects, the ultrafiltration water system is used as pre-treatment equipment for RO.
Turbid effluent may be related to damaged membrane modules, seal failure, severe membrane fouling, or abnormal system operating parameters. When abnormalities occur, check membrane integrity, connection components, and operating pressure, and perform cleaning, maintenance, or replacement of relevant components based on the test results.
- PVDF (polyvinylidene fluoride) offers advantages such as high elongation and resistance to fiber breakage. It can be used in environments containing strong acids, strong alkalis, and various organic solvents.
- PS (polysulfone) has good chemical stability and decent water permeability. It is suitable for conventional water treatment applications, such as municipal wastewater treatment and drinking water pretreatment.
- PVC (polyvinyl chloride) is widely available and inexpensive. It is suitable for projects with relatively low requirements for membrane materials, such as general industrial wastewater and agricultural water treatment.

Principle of Operation of an Ultrafiltration Water System
Under the action of an external force, the solution to be separated flows along the surface of the ultrafiltration membrane at a certain flow rate. The solvent, low-molecular-weight substances, and inorganic ions in the solution pass through the ultrafiltration membrane from the high-pressure side to the low-pressure side and are discharged as filtrate; meanwhile, high-molecular-weight substances, colloidal particles, and microorganisms in the solution are retained by the ultrafiltration membrane. The solution is concentrated and discharged as a concentrate.
What are the different types of ultrafiltration membranes?
Ultrafiltration membranes are classified into two types based on the filtration direction: external-pressure and internal-pressure. Both external-pressure and internal-pressure ultrafiltration membranes have their own advantages and disadvantages and are suitable for different applications.
- The advantages of external-pressure ultrafiltration membranes include high filtration efficiency, with a recovery rate of over 95%; they are suitable for treating water containing a high concentration of suspended solids; and the membrane modules can be used in reverse, offering strong adaptability. However, they also have some drawbacks, such as high requirements for membrane fiber strength, susceptibility to fouling, the need for regular backwashing, complex operation, certain requirements for feedwater quality, and high pretreatment demands.
- The advantages of internal-pressure ultrafiltration water system membranes include high fiber strength, strong resistance to fouling, simple operation and maintenance, and stable treated water quality, making them suitable for treating water sources with significant variations in water quality. However, their filtration recovery rate is relatively low, generally around 90 percent; they cannot be air-cleaned; backwashing effectiveness is limited; and although the inner walls are smooth, contaminants tend to accumulate in complex patterns during actual operation.
In practical applications, the choice between external-pressure and internal-pressure ultrafiltration membranes should be based on a comprehensive evaluation of specific water quality conditions, treatment requirements, and budget constraints.
Key Factors Affecting Ultrafiltration System Operation
- Feed Flow Rate
Increasing the feed flow rate can slow down concentration polarization and increase permeate flux; however, this requires higher operating pressure and results in increased energy consumption. Generally, the feed flow rate is controlled between 1 and 3 m/s.
- Temperature
The operating temperature primarily depends on the chemical and physical properties of the feed material and the membrane material. Since high temperatures can reduce the viscosity of the feed solution, increase mass transfer efficiency, and improve permeate flux, operation should be conducted at the highest permissible temperature.
- Operating Cycle
As the ultrafiltration water system process proceeds, a gel layer gradually forms on the membrane surface, causing the permeate flux to decline progressively. When the flux reaches a certain minimum value, cleaning is required; this period is referred to as an operating cycle. The duration of the operating cycle depends on the cleaning regimen.
- Feed Solution Pretreatment
To increase the membrane permeate flux and ensure the normal and stable operation of the ultrafiltration water system, the feed solution should be pretreated as needed. Commonly used pretreatment methods include precipitation, coagulation, filtration, and adsorption.
