PP Melt Blown Filter Cartridge 10 Micron 40 Inch: High Dirt Holding Pre-Filter For High Turbidity Raw Water
Introduction:If you are searching for PP Melt Blown Filter Cartridge 10 Micron 40 Inch for high turbidity raw water pretreatment and industrial liquid coarse filtration, this gradient polypropylene depth filter provides reliable 10 micron particle retention for heavy impurity loads. Constructed from virgin polypropylene with loose-outer and dense-inner fiber structure, it achieves large dirt holding capacity and stable low pressure drop under continuous high-flow operation. It efficiently removes coarse sediment, rust particles, large suspended solids and organic debris from raw water, reducing impurity burden for downstream fine filter cartridges and RO membrane systems. This economical disposable depth filter is widely used in municipal water pretreatment, power plant circulating water, mining water treatment and general industrial liquid filtration projects around the world.

Product Overview
PP Melt Blown Filter Cartridge 10 Micron 40 Inch is a widely adopted depth filter element for industrial first-stage water pretreatment. It is manufactured from virgin polypropylene resin through melt-blown one-piece thermal molding, without adding any adhesive. The gradient density fiber design enables multi-layer depth filtration instead of simple surface interception. Standard dimension is 40 inch length, 60mm outer diameter and 30mm inner diameter, compatible with all standard 40-inch filter housings. Compared with 1μm and 5μm fine filters, the 10 micron grade features more open fiber gaps, greatly resisting clogging when handling raw water with high sediment content. It serves as the primary barrier to capture bulk contaminants, protecting downstream precision filtration equipment and lowering overall system operation and maintenance cost.
Working Principle
PP Melt Blown Filter Cartridge 10 Micron 40 Inch works based on outside-in gradient depth filtration. When raw water flows through the cylindrical fiber matrix, large contaminants like sand grains and rust flakes are trapped on the outer loose fiber layers. Medium-sized suspended particles are captured in the middle fiber zone. Fine particles down to 10 micron are intercepted inside the denser inner fiber layers. This progressive interception mechanism prevents rapid surface blockage, extends service cycle and keeps pressure drop stable during long continuous running. Pure polypropylene material has good chemical inertness, suitable for most neutral and weakly acidic or weakly alkaline industrial aqueous liquids.

FAQ
Q1: When should I choose 10 micron melt blown filter instead of 5 micron?
A1: Select 10μm for raw water with high sediment and high turbidity. It has better anti-clogging performance and longer service life than finer grades.
Q2: What is the maximum operating temperature?
A2: Max continuous working temperature is 60℃. Higher temperature will deform polypropylene fiber and damage filtration performance.
Q3: Can this filter be cleaned and reused?
A3: It is disposable depth filter. Once differential pressure reaches 2.0 bar, replacement is required. Cleaning cannot restore original filtration performance.
Q4: Are different lengths available?
A4: Yes, 10,20,30 and 40 inch lengths are available, multiple micron ratings can be supplied for bulk orders.
