1. Product Introduction of High Flow Water Filter System

High flow water filter system is an integrated industrial filtration solution composed of stainless steel filter housing, multiple large flow filter cartridges, connecting pipelines, pressure gauges and quick opening components. As indispensable pretreatment equipment of ultrafiltration system, it is widely used in ultrapure water preparation, wastewater recycling, seawater desalination and other water treatment sectors. Raw water including groundwater, surface water and industrial recycled wastewater carries silt, rust debris, microfiber and organic colloids. Without effective interception by high flow water filter system, these tiny contaminants will continuously scour and block ultrafiltration membrane pores, resulting in irreversible membrane fouling, shortening membrane service life and increasing the frequency of chemical cleaning. Therefore, high flow water filter system has become standard matching facility for industrial ultrafiltration projects worldwide.

Raw water first removes massive sediment and rigid large particles through upstream liquid filter, then enters high flow water filter system to capture micro pollutants that threaten ultrafiltration membrane safety. We supply diversified filter products suitable for different ultrafiltration working environments:

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 medium treatment: deploy Premium High Flow Water Filter Element for Industrial Liquid Filtration

The core consumable inside high flow water filter system is pleated high flow filter cartridge. Common raw materials involve polypropylene, glass fiber and PTFE, covering precision from 1μm to 50μm. The filter housing adopts 304/316L stainless steel, supporting vertical and horizontal installation modes. Mainstream cartridge connection types are 226 fin interface and flat open end cap, compatible with most filter housings on the international market. All finished systems and supporting filter cartridges pass bubble point inspection and hydraulic pressure testing before shipment, ensuring stable coordinated operation with ultrafiltration equipment. Our factory supports supply of standard integrated systems and customized production for non-standard ultrafiltration engineering demands.

2. Working Principle: Collaborative Filtration with Ultrafiltration Equipment

The whole water purification workflow forms three-level progressive filtration: liquid filter coarse filtration → high flow water filter system precision filtration → ultrafiltration membrane deep separation. The integrated filter system traps contaminants of different particle sizes by physical interception, inertial deposition and adsorption of multi-layer pleated filter media.

2.1 Continuous Stable Filtration Operation

After preliminary coarse filtration by front liquid filter, raw water flows into stainless steel housing of high flow water filter system and permeates inward from the outer layer of filter cartridges to the central water collection pipeline. Large impurities are blocked on the outer surface of filter media, while tiny colloids and organic particles are trapped inside filter layers. Treated clean water converges inside central pipes and steadily flows into ultrafiltration equipment to remove bacteria, macromolecular organics and residual ultrafine suspended substances. The multi-cartridge parallel layout greatly improves overall water throughput, maintaining low system pressure drop under long-term continuous operation and avoiding insufficient water inflow during continuous water production of ultrafiltration units.

2.2 Differential Pressure Reminder for Cartridge Replacement

Pollutants will accumulate gradually on filter media during long-time operation, causing continuous growth of inlet and outlet differential pressure. When pressure difference reaches the warning threshold of 0.25MPa, operators need to replace internal filter cartridges timely. Blocked filter cartridges will increase water pump operating load, reduce ultrafiltration water yield and accelerate membrane contamination.

2.3 Coordination with Ultrafiltration Backwashing System

Water treated by high flow water filter system can be used as backwashing water source of ultrafiltration membrane modules. Mixed with compressed air to form gas-water cleaning medium, it can thoroughly flush pollutants attached on ultrafiltration membrane surface, effectively slow down membrane fouling and extend the chemical cleaning cycle of ultrafiltration equipment.

FAQ

Q1: What protection can high flow water filter system bring to ultrafiltration equipment?

A: This integrated filter system effectively intercepts various impurities inside raw water, reduces pollutant load on ultrafiltration membranes, slows down fouling speed, extends membrane service life and decreases shutdown maintenance frequency of ultrafiltration production lines.

Q2: Can you customize high flow water filter system to match our existing ultrafiltration unit?

A: Yes. Our technical team adjusts housing volume, cartridge quantity, filter length and interface according to on-site water quality, system flow and pipeline layout to achieve perfect matching with your ultrafiltration equipment.

Q3: What is the regular replacement cycle of filter cartridges inside high flow water filter system?

A: Under stable clean water quality, the replacement cycle is 1–3 months. If raw water turbidity keeps high, differential pressure rises rapidly and service life will be shortened significantly.

Q4: Why install liquid filter upstream of high flow water filter system in ultrafiltration pretreatment pipeline?

A: The front liquid filter captures gravel, rust blocks and large hard impurities, preventing sharp particles from scratching filter media, delaying cartridge clogging and forming dual protection for downstream ultrafiltration membranes.

Q5: Which factors lead to premature blockage of high flow water filter system?

A: Excessive impurity concentration of inlet water, malfunction of upstream liquid filter, long-term overload flow operation and improper selection of filtration precision will trigger rapid differential pressure increase and early clogging.

Q6: Can multiple high flow water filter systems operate in parallel to supply water for large industrial ultrafiltration units?

A: Definitely yes. Multiple filter systems can be arranged in parallel on the pipeline, providing stable large-flow qualified water for heavy-duty ultrafiltration equipment, widely applied in municipal reuse water and industrial water treatment projects.
