MFNP050‑40N‑ITT Cartridge Filters for Ultrafiltration System Pretreatment
MFNP050‑40N‑ITT cartridge filtersserve as critical pretreatment components for industrial ultrafiltration systems. This liquid filter delivers high‑capacity particle removal while reducing frequent cartridge replacement frequency. Manufactured with robust pleated polypropylene media, it fits standard high‑flow filter housings and works well with High‑flow water filter cartridge and Water Filtration PP Pleated Filter for complete water treatment workflows. It is widely selected for food‑beverage, power generation and chemical process water purification across global markets.
MFNP050‑40N‑ITT cartridge filters are high‑flow pleated filter elements specially engineered for ultrafiltration pretreatment protection. As a reliable replacement‑grade industrial filter cartridge, it is designed to intercept suspended solids, colloids, fine sediments and granular contaminants before raw water enters ultrafiltration membrane modules, effectively mitigating membrane fouling and extending the service life of costly UF membranes.
Different from small‑size standard filter cartridges, this MFNP050‑40N‑ITT cartridge adopts large‑diameter pleated structure, which greatly expands the effective filtration area. Under equivalent working conditions, it can achieve higher flow rate with fewer filter elements inside the filter housing. For system integrators and end‑users, it cuts housing quantity, installation workload and later‑stage maintenance cost. When configuring the whole filtration skid, users can match it with High Flow Pleated Filter Cartridge for Industrial UF System and Replace Pall Marksman High‑Flow Cartridge to realize multi‑grade pre‑filtration gradient interception effect.
The whole element applies full polypropylene construction, without adhesive additives that may release harmful substances. The thermal‑bond pleating process avoids secondary pollution caused by glue dissolution in water flow. This characteristic makes it suitable for water‑treatment scenarios with strict sanitary requirements. The end cap and inner‑outer support skeleton are integrally molded, ensuring structural stability under long‑term high‑flow impact and frequent pressure fluctuation. Whether for new‑built ultrafiltration equipment or for spare‑part update of existing water treatment lines, MFNP050‑40N‑ITT cartridge filters can provide stable and consistent pretreatment performance.
MFNP050‑40N‑ITT cartridge filters adopt surface‑depth composite pleated filtration principle. After raw water enters the filter housing, fluid flows from the outer surface of the filter cartridge radially inward. Large‑size particles are firstly trapped on the outer pleated surface, while tiny impurities penetrate into the depth of polypropylene fiber layers and are intercepted by dense fiber gaps.
The large‑area pleated layout spreads contaminants over the whole filter medium instead of accumulating only on partial local surface. This design slows down pressure‑rise speed, prolongs service cycle and maximizes the dirt‑holding capacity. When the differential pressure between inlet and outlet reaches the preset threshold, it indicates that the filter medium is fully loaded with intercepted pollutants, and operators need to replace the whole cartridge.
As the front‑guard of ultrafiltration equipment, its core working value lies in removing most particulate pollutants in advance. If raw water directly flows into UF membranes without such pretreatment protection, particulate pollutants will deposit on membrane surface, block membrane pores, accelerate membrane fouling, increase chemical cleaning frequency and even cause irreversible membrane damage. Cooperated with PFTM11UNF high flow filter cartridge in multi‑stage filtration, it can further optimize overall water‑treatment stability. It should be noted that this element is for particle impurity removal, and it cannot remove dissolved ions in water, so it only undertakes pretreatment work before ultrafiltration.

Each batch of MFNP050‑40N‑ITT cartridge filters goes through complete production‑process inspection and finished‑product testing before delivery. Raw‑material incoming inspection is carried out for polypropylene filter cloth, support skeleton and end‑cap materials to guarantee raw‑material consistency. During production, pleating amplitude, thermal‑bond strength and end‑connection sealing performance are sampled and checked.
Finished‑product tests include bubble‑point integrity test, pressure‑resistant cyclic impulse test and water‑flow pressure‑drop detection. Defective products with medium crack, poor sealing and structural looseness will be eliminated. The whole production process avoids glue bonding, so there is no risk of adhesive dissolution contaminating process water.
All products are produced following industrial filtration quality management standards. Each cartridge is individually packaged to prevent dust and particle pollution during storage and transportation. We provide complete product technical sheets for engineering design reference. It is worth emphasizing that field installation inspection is still required before putting into service, to confirm matching with filter‑housing interface and sealing condition.
MFNP050‑40N‑ITT cartridge filters are mainly used as pretreatment filter for ultrafiltration water‑treatment systems, also widely applied in multiple industrial liquid‑filtration scenarios.
Industrial ultrafiltration system pretreatment: Intercept sediment, iron‑oxide scale, suspended particles, protect UF membrane elements, reduce membrane cleaning frequency, suitable for circulating water, raw‑water purification projects.
Power plant water treatment: Boiler make‑up water, condensate pre‑filtration, remove pipeline rust particles and suspended pollutants.
Food & beverage industry: Raw‑water pretreatment for beverage, drinking‑water production, filter out granular impurities.
Chemical industry: Process water filtration for chemical production, pre‑treatment of circulating cooling water.
Municipal water‑works: Large‑volume raw‑water pre‑filtration for municipal water supply and reclaimed‑water reuse projects.
Pharmaceutical & cosmetic water‑making: Sanitary‑grade process‑water pre‑filtration for pharmaceutical water‑preparation equipment.
In different application industries, combined with actual raw‑water turbidity and pollutant composition, users can set multi‑stage gradient filtration to achieve better overall filtration effect.
A: It works as ultrafiltration pretreatment protection filter. It intercepts suspended solids, sediments and granular contaminants in raw water, lowers pollutant load on ultrafiltration membranes, delays membrane fouling, reduces chemical cleaning frequency and extends UF membrane service life.
A: There is no fixed service‑life time standard. The service cycle is mainly determined by raw‑water turbidity, pollutant content and actual flow rate. Normally, replace the cartridge when system inlet‑outlet differential pressure reaches 0.35MPa.
A: This is disposable pleated filter element. After pollutants fill the filter‑medium gap, back‑washing cannot fully restore original filtration performance. Reuse after cleaning will bring risk of particle leakage. It is recommended to adopt direct‑replacement mode.
A: It adapts to 40‑inch large‑flow filter housing matching ITT special connection interface. Before purchasing, please confirm housing interface size, inner‑chamber space and pressure‑bearing rating to avoid installation mismatch.
A: The polypropylene material has good tolerance for weak acid and weak‑alkali water‑phase medium. It is not suitable for long‑term working under high‑concentration strong acid or strong‑alkali operating conditions. Please consult technical support for special chemical‑medium working condition evaluation.
A: The quantity calculation depends on system total flow rate, single‑cartridge allowable flow and raw‑water quality. It is suggested to calculate the required quantity combined with technical parameter sheet, and properly reserve surplus for fluctuating water‑quality working conditions。
