Product Overview
High Flow Filter Cartridge is important consumable for liquid‑pretreatment, and ultrafiltration membrane module LF‑UF‑8060W PVDF external‑pressure UF‑membrane belongs to Water Filter Element product‑line. It adopts high‑strength PVDF hollow‑fiber material with outstanding oxidation‑resistance and acid‑alkali‑tolerance. As core pretreatment equipment for water‑treatment system, it intercepts colloid, bacteria, suspended‑solid in sewage, lowering SDI value of feed‑water, effectively protecting downstream reverse osmosis membrane element for municipal sewage‑reuse and industrial circulating‑water recovery projects.

Municipal Sewage Reuse & RO Pretreatment Application Scenarios
LF‑UF‑8060W ultrafiltration membrane module is widely used for municipal secondary‑effluent reuse project. After biochemical‑treatment sewage passes this PVDF external‑pressure UF‑module; suspended‑solid, colloid and most bacteria are intercepted, feed‑water SDI value drops stably, creating qualified incoming‑water condition for subsequent RO desalination system. It is also used for industrial park circulating‑water recovery, mining‑waste‑water pretreatment. It can cooperate with High Flow Filter Cartridge as pre‑security‑filter before UF‑module to reduce large‑particle impact to hollow‑fiber filaments. PVDF material can tolerate frequent sodium‑hypochlorite chemical‑enhanced back‑wash, which is very suitable for high‑pollution sewage‑source environment. For filter‑element manufacturing QC‑reference please refer to Interchangeable Hydraulic Filter Elements quality‑control‑system.
Core Product Advantages
PVDF hollow‑fiber material has excellent anti‑oxidation and chlorine‑resistance performance, adapts frequent oxidant‑containing chemical‑back‑wash cycles. External‑pressure structure bears high pollutant‑load capacity, fits sewage‑source with high suspended‑solid content. Hollow‑fiber filament owns high mechanical‑strength, low filament‑breakage‑rate under long‑term cross‑flow / dead‑end filtration running. Wide pH tolerance range satisfies complex industrial sewage‑cleaning requirement. Standard module dimension fits mainstream UF‑skid‑equipment for direct replacement. Every UF‑module completes bubble‑point integrity‑test before factory‑delivery.
