Folded high flow water filter element, also known as pleated high flow cartridge, is a cylindrical precision filter developed for large-flow industrial water treatment. It acts as critical security filtration consumable inside filter housing and serves as the primary protection barrier for ultrafiltration membrane components. Raw water including groundwater, surface water and industrial reclaimed wastewater contains silt, rust particles, fine fibers and organic colloids. Without effective interception by folded high flow water filter element, these tiny contaminants will continuously scour and block ultrafiltration membrane pores, trigger irreversible membrane fouling, shorten membrane service life and increase the frequency of chemical cleaning. Therefore, folded high flow water filter element has become standard matching filter material for industrial ultrafiltration projects all over the world.
Raw water firstly removes massive sediment and rigid large particulate impurities through upstream liquid filter, then flows into filter housing and is purified by folded high flow water filter element to capture micro pollutants that threaten ultrafiltration membrane safety. We supply multiple filter products adapting different ultrafiltration working conditions:
For large-scale ultrapure water ultrafiltration pretreatment projects: select High Flow Filter Element
For seawater desalination and circulating water ultrafiltration systems: adopt 60" PP High Flow Water Filter for Industrial Ultrafiltration Systems
For municipal reclaimed water reuse ultrafiltration stations: use Pleated High Flow Filter Cartridge for Ultrafiltration Water Treatment
For chemical wastewater and weakly corrosive liquid treatment: deploy Premium High Flow Water Filter Element for Industrial Liquid Filtration
The folded high flow water filter element consists of folded filter media, internal reinforced support core, upper and lower end caps and sealing rings. Main available materials include polypropylene, glass fiber and PTFE, with filtration precision ranging from 1μm to 50μm. The mainstream connection modes are 226 fin interface and flat open end cap, compatible with most stainless steel filter housings on international market. All finished folded high flow water filter elements pass bubble point test and hydraulic pressure inspection before delivery, guaranteeing stable coordinated operation with ultrafiltration equipment. Our factory supports standard specification stock supply and customized production to satisfy non-standard ultrafiltration engineering demands.
The whole water purification workflow forms three-level progressive filtration: liquid filter coarse filtration → folded high flow water filter element precision filtration → ultrafiltration membrane deep separation. The folded filter element captures contaminants of different particle sizes via physical interception, inertial deposition and adsorption of multi-layer folded filter media.
After preliminary coarse filtration by front liquid filter, raw water enters the stainless steel filter housing, permeates inward from the outer layer of folded filter media to the central water collecting pipeline. Large-size impurities are trapped on the outer surface, and tiny colloids and organic particles are intercepted inside filter layers. Clean treated water converges inside central pipeline and steadily flows into ultrafiltration equipment to remove bacteria, macromolecular organics and residual ultrafine suspended substances. The intensive folded structure greatly expands effective filtration area, maintaining low system pressure drop under long-term continuous high-flow operation and avoiding insufficient water inflow during continuous water production of ultrafiltration units.
Pollutants gradually accumulate on folded filter media during long-time operation, leading to continuous rise of inlet and outlet differential pressure. When pressure difference reaches the warning value of 0.25MPa, operators need to replace folded high flow water filter element in a timely manner. Blocked filter elements will increase water pump operating load, reduce ultrafiltration water output and accelerate membrane contamination.
Water treated by folded high flow water filter element can be adopted as backwashing water source of ultrafiltration membrane modules. Mixed with compressed air to form gas-water cleaning medium, it can thoroughly wash pollutants attached on ultrafiltration membrane surface, effectively slow down membrane fouling and extend the chemical cleaning cycle of ultrafiltration equipment.

Q1: What protective effect can folded high flow water filter element bring to ultrafiltration equipment?
A: It effectively intercepts various impurities inside raw water, reduces pollutant load on ultrafiltration membranes, slows down fouling speed, extends membrane service life and lowers shutdown maintenance frequency of ultrafiltration production lines.
Q2: Can you customize folded high flow water filter element to match our existing ultrafiltration system?
A: Yes. Our technical team adjusts filter length, precision and interface according to on-site water quality, system flow and filter housing parameters to achieve perfect matching with your ultrafiltration equipment.
Q3: What is the standard replacement cycle of folded high flow water filter element?
A: Under stable clean water quality, the replacement cycle is 1–3 months. If raw water turbidity remains high, differential pressure rises rapidly and service life will be shortened significantly.
Q4: Why install liquid filter upstream of folded high flow water filter element in ultrafiltration pretreatment pipeline?
A: The front liquid filter traps gravel, rust blocks and large hard impurities, preventing sharp particles from scratching folded filter media, delaying filter clogging and forming dual protection for downstream ultrafiltration membranes.
Q5: What factors cause premature blockage of folded high flow water filter element?
A: Excessive impurity concentration of inlet water, failure of upstream liquid filter, long-term overload flow operation and improper precision selection will lead to rapid differential pressure growth and early clogging.
Q6: Can multiple folded high flow water filter elements run in parallel to supply water for large industrial ultrafiltration units?
A: Definitely yes. Multiple filter elements can be installed in parallel inside large filter housing, supplying stable large-flow qualified water for heavy-duty ultrafiltration equipment, widely used in municipal reuse water and industrial water treatment projects.
