PP cotton

High-Efficiency Sediment Filtration Solution

Product Overview

PP Cotton Filter Cartridge, also known as PP Sediment Filter, is made from 100% polypropylene fiber using melt-blown technology.
It is designed to effectively remove sand, rust, silt, suspended solids, and large particulate impurities from water, serving as the first-stage filtration in water treatment systems.

PP cotton filters are widely used in RO systems, ultrafiltration systems, industrial pretreatment, and household water purification.

Working Principle

PP cotton filters work through depth filtration:

  • Water flows from the outer layer to the inner layer of the cartridge

  • Larger particles are trapped on the outer layers

  • Smaller particles are captured in the inner layers

  • This gradient density structure ensures high dirt-holding capacity and low pressure drop

Key Features & Advantages

  • High filtration efficiency

  • Strong dirt-holding capacity

  • Low pressure loss

  • No chemical additives

  • Corrosion and acid resistance

  • Stable performance

  • Cost-effective and disposable

Application Areas


Installation Position

  • Installed in cartridge filter housings

  • Used as pre-filtration before RO membranes

  • Suitable for single-core and multi-core filter housings


Reliable Pretreatment Consumable

PP cotton filter cartridges provide effective protection for downstream membranes and equipment, extending service life and ensuring stable system operation.
