Water Filtration PP Pleated Filter | Industrial Polypropylene Pleated Water Filter Cartridge

Water Filtration PP Pleated Filter is a professional polypropylene pleated filter cartridge designed for general industrial water purification and process liquid filtration. With multi-layer gradient PP pleated media and large effective filtration area, this water filtration PP pleated filter efficiently removes suspended solids, sediment, rust and colloidal particles from raw water, providing reliable pre-filtration protection for RO, NF and UF membrane systems. Manufactured by adhesive-free thermal fusion technology, it features excellent chemical stability, no material precipitation and no secondary water pollution. Widely applicable for industrial circulating water, boiler make-up water, food beverage water and municipal water treatment, this filter element supports direct replacement of mainstream filter housings. Most water treatment projects adopt RTM41HF050E filter cartridge and HFU660CAS010JUW filter element together with water filtration PP pleated filter to build stable multi-stage water purification systems.

Product Overview

Water Filtration PP Pleated Filter is a universal industrial-grade pleated filter element specially developed for water treatment purification. Different from ordinary melt-blown PP filters, it adopts precise radial pleated structure and multi-layer gradient polypropylene filter media, which greatly increases filtration area and improves dirt holding capacity and filtration stability. The full polypropylene structure ensures outstanding acid and alkali resistance, making it suitable for most neutral and weak corrosive water quality environments. With complete specifications ranging from 1μm to 100μm precision and multiple length options, the water filtration PP pleated filter can meet coarse pre-filtration and fine polishing requirements in various industrial water treatment processes.

Water Filtration PP Pleated Filter plays an indispensable pre-protection role in industrial water treatment systems. It effectively intercepts particulate impurities in raw water, reduces water turbidity, prevents membrane blockage and contamination, and significantly extends the service life of membrane elements, pumps and downstream precision equipment. Imported original PP pleated water filters have stable performance but high cost and long delivery cycles. As a professional filter manufacturer, our interchangeable water filtration PP pleated filter strictly complies with international production standards and dimensional accuracy. Each batch is inspected by bubble point test and pressure tightness test before delivery to ensure stable and consistent filtration performance for long-term industrial operation.

Core specifications of Water Filtration PP Pleated Filter: Filter media: 100% pure polypropylene gradient pleated fiber; micron rating: 1–100μm; common lengths: 10/20/40/60 inch; structure: standard radial pleated structure; end cap type: DOE / 222 / 226 optional; molding technology: adhesive-free thermal fusion integral molding; O-ring material: NBR, EPR, silicone, FKM optional; max continuous working temperature: 60℃; working pH range: 5–9; recommended replacement differential pressure: 2.4 bar; compatible with mainstream industrial filter housings.

The replaceable water filtration PP pleated filter supports direct drop-in installation without modifying existing filter equipment. With high filtration accuracy, large dirt holding capacity and cost-effective performance, it is the most widely used universal filter consumable for industrial water pretreatment and process water purification.

Filtration Working Principle

Water Filtration PP Pleated Filter adopts surface-depth composite gradient filtration principle. Under the operating pressure of the water system, raw water flows evenly through multi-layer pleated PP media. Large particle impurities such as sediment and rust are trapped on the outer coarse pleated layer, while fine suspended solids and colloidal micro-particles are deeply intercepted by the inner dense gradient fiber layer. The uniform pleated structure optimizes water flow distribution, reduces local flow velocity and pressure loss, and avoids rapid filter blockage. Adhesive-free thermal fusion structure eliminates chemical glue dissolution and secondary water pollution. When the inlet-outlet differential pressure reaches 2.4 bar, the filter element is fully saturated with pollutants and needs timely replacement to maintain stable effluent water quality and system efficiency.

FAQ

Q1: What is Water Filtration PP Pleated Filter used for?

A1: It is a polypropylene pleated filter element used for industrial water filtration, mainly to remove sediment, suspended solids, colloids and fine particles, protecting downstream membrane systems and precision water treatment equipment.

Q2: What is the advantage of PP pleated filter over melt-blown filter?

A2: PP pleated filter has larger filtration area, higher flow rate, greater dirt holding capacity and longer service life, more suitable for continuous industrial water treatment.

Q3: When should I replace the water filtration PP pleated filter?

A3: Replace immediately when the inlet-outlet differential pressure reaches 2.4 bar. High-turbidity raw water will shorten the service life accordingly.

Q4: Can the PP pleated water filter be cleaned and reused?

A4: It is a disposable filter consumable. Fine impurities penetrate deep into the gradient fiber layer, and backwashing cannot fully restore filtration performance, so disposable replacement is recommended.

Q5: How to choose the right model of PP pleated filter?

A5: Confirm filtration precision, length, end cap type, O-ring material and working temperature, or provide original part number for accurate matching.
