High Flow Liquid Filter for Industrial Ultrafiltration Systems
High flow liquid filter is a widely adopted consumable for industrial ultrafiltration pretreatment and large-scale liquid purification projects. This liquid filter maximizes filtration area through folded pleated media design to achieve large throughput with low pressure drop. Our HFU640UY045JUW high flow filter cartridge belongs to this product series, which can effectively protect ultrafiltration membranes and seawater reverse osmosis element from particulate contamination. Our high flow liquid filters are manufactured with premium filter media, offering reliable particle retention performance and long service cycles for water treatment, chemical, power and seawater desalination industries.
High flow liquid filter is a high-capacity pleated filter cartridge installed inside filter housings, acting as the front pretreatment unit of ultrafiltration equipment. Traditional filter cartridges have limited filtration area, requiring dozens of cartridges to handle large liquid flow. The pleated structure of high flow liquid filter greatly expands the effective filtration surface area within one single cartridge. It can deliver high liquid flow rate while keeping low differential pressure, which reduces the total quantity of filter elements required in the system, saving installation space, cutting inventory cost and simplifying routine maintenance work. Our High-Flow Pod Filter is the classic high flow liquid filter product, designed for industrial water pretreatment before ultrafiltration systems.
In a complete ultrafiltration water treatment workflow, raw water usually carries sediment, algae, suspended solids, colloids and large organic particles. Without proper pre-filtration, these impurities will directly scour and block ultrafiltration membrane modules, causing irreversible membrane fouling and shortening membrane service life. High flow liquid filter acts as the first defensive line to trap these large pollutants. For raw water with high turbidity, we can also equip Glass Fiber Filter Cartridge as secondary filtration to further reduce feed water SDI value and stabilize the running status of ultrafiltration equipment.
We supply multiple types of high flow liquid filters with different filter media, including polypropylene, glass fiber and composite media. Different end cap designs and sealing options are available to match most standard industrial filter housings. Our high flow liquid filter can also be used as replacement elements for mainstream brand housings, such as our Pall Ultipleat High Flow Element replacement version. Whether for small skid-mounted ultrafiltration devices or large centralized industrial water treatment stations, high flow liquid filter can be configured to meet customized flow and precision requirements.
The working principle of high flow liquid filter relies on surface filtration and depth filtration based on folded filter media. Raw liquid flows into the filter housing and enters from the outer wall of the high flow liquid filter cartridge. As the liquid passes through the multi-layer folded filter media, solid particles, colloids and impurities are captured on the surface and inside the pores of filter media. The purified liquid flows into the inner core of the cartridge and flows out from the outlet of filter housing.
The pleated design is the core advantage of this filter. By folding flat filter media into dense wrinkles, the usable filtration area increases many times compared with non-pleated filter cartridges of the same length. Larger filtration area means higher liquid throughput and slower pressure difference rise during operation, which is the key reason high flow liquid filter is widely used for ultrafiltration pretreatment.
When integrated with ultrafiltration equipment, the full treatment sequence is raw water intake → high flow liquid filter pre-filtration → ultrafiltration membrane separation → advanced treatment. The pre-filter removes large contaminants in advance, so only tiny micro-particles can reach the ultrafiltration membrane. Our Replace Pall Water Filter Element adopts the same pleated high flow filtration principle. Operators monitor the inlet and outlet pressure difference. When the differential pressure rises to the preset threshold, the high flow liquid filter cartridge needs replacement to recover filtration performance and protect downstream ultrafiltration membranes.

The selection of high flow liquid filter parameters should be determined by raw water quality and ultrafiltration system design. Higher filtration precision will reduce the maximum flow rate, so we balance flow capacity and retention accuracy for each project. Our Equivalent Pall Filter HFU660GF060H13 shares the same technical specifications and can directly replace original filter elements without modifying filter housings.
Every high flow liquid filter undergoes strict multi-step quality control during production. Raw filter media will be tested for bubble point, tensile strength and chemical compatibility before pleating and assembly. After folding, thermal welding and end cap bonding, each finished high flow liquid filter will carry out bubble point leak detection one by one, to check for pinholes, media damage and sealing defects.
We follow ISO industrial filtration manufacturing standards for batch production. Material certificates, batch test reports and bubble point inspection records can be provided for project bidding and factory audit. Accelerated fouling simulation tests are performed in our factory to verify long-term stability of high flow liquid filter under real industrial operating conditions.
Our professional technical team offers full-cycle support, including system flow calculation, filter housing selection, installation guidance and maintenance training for high flow liquid filter and ultrafiltration systems. We also provide after-sales consultation about cartridge replacement, pressure difference monitoring and membrane protection solutions.
High flow liquid filter is widely used as the pretreatment filter for ultrafiltration equipment across multiple industries.
Seawater Desalination High flow liquid filter removes sediment, algae and suspended solids from raw seawater, protecting ultrafiltration and seawater reverse osmosis membrane elements. It is widely applied in island water supply and coastal desalination plants.
Power Plant Water Treatment Coastal and inland thermal power plants install high flow liquid filter before ultrafiltration units to treat boiler make-up water, reduce impurity load and extend ultrafiltration membrane service life.
Chemical Industrial Liquid Purification Chemical factories use high flow liquid filter to filter process water and cleaning liquid, intercepting solid particles to protect downstream ultrafiltration and membrane separation equipment.
Food & Beverage Water Treatment Food and beverage factories adopt high flow liquid filter + ultrafiltration system to purify raw water, meeting sanitary water standards for beverage production.
Mining Wastewater Recycling Mining sites use high flow liquid filter as pretreatment for mine wastewater, cooperating with ultrafiltration equipment to realize wastewater recycling and water resource reuse.
Municipal Water Treatment Projects Large municipal water plants deploy high flow liquid filter as pretreatment unit of ultrafiltration systems for tap water upgrading and water purification.
A: High flow liquid filter is a large-capacity filter cartridge with folded pleated filter media. It features large filtration area, high liquid throughput and low pressure drop, commonly used as pretreatment for industrial ultrafiltration systems.
A: Raw water contains sediment, colloids and suspended particles. High flow liquid filter captures these contaminants in advance, preventing fouling and physical scratch damage to ultrafiltration membranes and reducing maintenance cost.
A: Main media choices include polypropylene, glass fiber and composite pleated media. PP media suits general water treatment; glass fiber is suitable for high-temperature liquid and fine particle filtration.
