Big Flow Rate Filter Cartridge for Ultrafiltration Feed Water Safeguard

Big flow rate filter cartridge belongs to core security filtration consumables in the pretreatment section of ultrafiltration systems, replacing dozens of traditional small-size filter cartridges with single large-flow output, simplifying the layout of filter tanks, valves and supporting pipelines for ultrafiltration supporting facilities. Conventional small filter elements require a large number of installations to meet the water intake demand of medium and large ultrafiltration units, which brings heavy workload for daily inspection and regular replacement. The 152mm outer diameter lengthened body design of big flow rate filter cartridge greatly reduces the quantity of filter housings for ultrafiltration pretreatment, lowering initial equipment investment and manual maintenance costs synchronously.
Raw water first removes large solid pollutants through the upstream liquid filter, then flows into the big flow rate filter cartridge for precision interception of tiny impurities that are easy to block ultrafiltration membrane pores, avoiding irreversible scratch and pollution damage to ultrafiltration membranes. We supply serialized big flow rate filter products to satisfy differentiated working condition demands of various ultrafiltration projects:
For high-standard electronic ultrapure water ultrafiltration pretreatment: pick High-Flow Filter Cartridges: The Pinnacle of Performance in Industrial Filtration
For municipal reclaimed water reuse ultrafiltration stations: apply High-Flow Filter Cartridges: Redefining Industrial Water Purification
For petrochemical wastewater tubular ultrafiltration front protection: adopt High Flow Filter Cartridge: Maximizing Efficiency in Industrial Liquid Treatment
For high-turbidity raw water and corrosive water quality ultrafiltration projects: deploy Premium High Flow Filter Cartridges – Engineered for Harsh Working Conditions
The overall structure of big flow rate filter cartridge consists of gradient pleated filter medium, integral injection molding PP reinforcement skeleton, upper and lower injection molding end caps, high-sealing EPDM rubber ring and external anti-collision protection cage. Optional filter media include polypropylene, glass fiber and PTFE; optional filtration precision ranges from 1μm to 50μm; mainstream connection modes are 226 fin type and flat open end cap, compatible with most mainstream big flow filter housings on the global market. All finished cartridges need to pass bubble point test and hydraulic burst test before delivery to ensure zero leakage during long-term coordinated operation with ultrafiltration equipment. Our factory supports fast delivery of standard specifications and personalized customization of length, precision and sealing materials for non-standard ultrafiltration projects.
The overall filtration chain is divided into three progressive levels: liquid filter coarse filtration → big flow rate filter cartridge precision filtration → ultrafiltration membrane deep separation. The filter cartridge relies on physical interception, inertial deposition and adsorption capture of gradient folded layers to layer-by-layer trap pollutants of different particle sizes.
After preliminary purification by the front liquid filter, raw water enters the filter housing and permeates inward from the outer folded wall of the big flow rate filter cartridge to the central water collection pipe. Large particles are trapped by the outer coarse filter layer, while micro colloids and organic matter are locked by the inner fine filter layer. Clean water converges into the central pipeline and stably enters the ultrafiltration host to complete the removal of bacteria, macromolecular organics and tiny particulate pollutants. The optimized folded structure maintains low system pressure drop under high flow rate, and will not cause insufficient water supply during continuous water production of ultrafiltration equipment.
Pollutants will continuously accumulate in the folded gaps as filtration proceeds, leading to a gradual rise in the inlet and outlet pressure difference of the filter tank. When the pressure difference reaches the warning value of 0.25MPa, the staff needs to replace the filter cartridge in time. Blocked filter cartridges will increase the operating load of the water pump, reduce the water inflow of ultrafiltration equipment, and accelerate the fouling speed of ultrafiltration membranes.
The clean water filtered by the big flow rate filter cartridge can be directly used as the backwashing water source of ultrafiltration membrane modules. After mixing with compressed air to form gas-water mixed cleaning medium, it can thoroughly flush the pollutants attached to the membrane surface, effectively slow down the fouling rate of ultrafiltration membranes and extend the chemical cleaning cycle of ultrafiltration equipment.

Q1: What core protective value can big flow rate filter cartridge bring to industrial ultrafiltration equipment?
A: It effectively intercepts fine impurities in raw water, reduces the pollutant load on ultrafiltration membranes, slows down membrane fouling speed, extends the service life of ultrafiltration modules, and reduces the frequency of shutdown maintenance for ultrafiltration production lines.
Q2: Can we customize the filter material, precision and length of big flow rate filter cartridges according to our own ultrafiltration system conditions?
A: Yes. Our technical team can adjust all structural parameters of the filter cartridge combined with on-site water quality, system total flow and existing filter housing size to achieve seamless matching with your ultrafiltration equipment.
Q3: What is the normal service life and replacement cycle of standard big flow rate filter cartridges?
A: Under clean water quality environment, the replacement cycle is 1.5 to 3 months; if the raw water turbidity is high and impurity content is large, the pressure difference rises rapidly, and it needs to be replaced within one month.
Q4: Why must an industrial liquid filter be installed upstream of the big flow rate filter cartridge for ultrafiltration pretreatment?
A: The front liquid filter intercepts hard impurities such as gravel and rust blocks to avoid sharp solids scratching the folded filter surface of the big flow rate cartridge, reduce the pollution speed of the filter element itself, and form dual protection for downstream ultrafiltration membranes.
Q5: What factors will cause premature blockage of big flow rate filter cartridges in actual operation?
A: Excessive impurity concentration in inlet water, failure of the front liquid filter, long-term overload flow operation and excessively small selected filtration precision will lead to rapid differential pressure rise and early blockage of filter cartridges.
Q6: Can multiple big flow rate filter cartridges be installed in parallel to supply water for super large industrial ultrafiltration units?
A: Parallel installation inside a single large-flow filter housing is fully supported. Multiple filter cartridges work synchronously to provide stable ultra-large flow qualified water for heavy-duty ultrafiltration equipment, which is widely used in large-scale municipal desalination and power plant water treatment projects.
