PP Melt Blown Cartridge Filter For Water Treatment

How Does A PP Melt Blown Filter Work?

A PP melt blown filter operates through a two-step process: melt blowing and formation of the cartridge. The process begins by melting down Polypropylene (PP) plastic into a liquid form. This molten PP is then blown by hot, high-velocity air or gas to form an excellent fibrous structure, a method known as ‘melt blowing.’ During this phase, tiny fibers are created, diminishing in diameter as they cool and solidify. This leads to the creation of a dense web-like structure with a graded pore size, which is ideal for filtration.
Subsequently, the web-like structure is wound tightly around a core, forming the cartridge. The winding process ensures varied density, with the outer layers having larger pores to trap larger particulates and the inner layers having smaller pores for finer filtration. This unique structure allows the PP Melt Blown Filter Cartridges to capture and hold a high volume of impurities, thus delivering superior filtration performance.

What Are The Differences Between PP Melt Blown Filters and String Wound Filters?

PP melt blown filters have a higher filtration efficiency than string wound filters in general, particularly when it comes to capturing smaller particles. Because fine fibers in melt blown filters produce a denser matrix with more surface area for particles to adhere to, the capture rate is higher. PP melt blown filters are highly efficient at removing fine particles from fluids because they can capture particles as small as 0.3 microns in diameter. String wound filters, on the other hand, are better adapted for removing larger particles and sediment and are less effective at capturing tiny particles.

Types of PP Melt Blown Filter

PP melt blown sediment filter: This type of filter has dense polypropylene microfibers, which results in high particle retention. Its graded pores ensure deep filtration, capturing contaminants of varying sizes.

Slotted PP sediment filter: This variant has grooves on the core surface, which increases filtration efficiency. The slotted design enhances the sediment filtration process and is particularly effective in trapping impurities.

Components of PP Melt Blown Filter

Polypropylene Microfibers

These ultra-fine fibers, formed through the melt-blown process, are the primary material in these filter cartridges. Their small diameters ranging from 0.5-10 micrometers, allow for excellent particle retention.

Filter Media

The densely packed polypropylene microfibers create a high-porosity filter media, which offers superior filtration capabilities while maintaining a low-pressure drop.

Core

The core provides structural support to the filter cartridge, ensuring its integrity even under high-pressure operations. It is typically made of polypropylene to maintain overall compatibility and safety.

End Caps

These are securely attached to each end of the filter cartridge and assist in sealing the cartridge within the filter housing, preventing any bypass of unfiltered fluid.

Gaskets/O-Rings

These components ensure a secure seal within the filter housing to prevent leakage or bypass of unfiltered fluid.

Process of PP Melt Blown Filter

Material preparation: The first step involves the preparation of the polypropylene (PP) material. This consists of the proper cleaning, drying, and de-dusting of the raw material.

Melt blowing: The prepared PP material is then melted at a high temperature, forming a molten polymer solution.

Fiber extrusion: The molten polymer is extruded through small nozzles, creating thin streams of polymer. High-speed hot air is blown at the streams, stretching them into wonderful fibers.

Web formation: The fine fibers are collected on a rotating drum or a conveyor to form a self-bonding web. The thickness of the web can be adjusted depending on the desired filtration efficiency.

Cooling and solidification: The web is cooled, allowing the fibers to solidify and bond together.

Roll winding and cutting: The resultant non-woven filter media is then wound onto rolls and cut into the desired lengths to create the final PP melt-blown filters.
