Ordinary brackish Reverse Osmosis membrane cannot withstand 32000ppm high-salinity seawater and maximum 800psi extreme working pressure, which will cause irreversible separation layer rupture of Reverse Osmosis membrane element and rapid flux attenuation after short-term continuous running. LF-SW series marine dedicated Reverse Osmosis membrane filter adopts fully reinforced spiral winding integral structure, which can realize single-stage one-time fresh water production with stable 99.7 salt rejection rate without secondary concentration treatment. This special high-pressure resistant RO membrane must be equipped with multi-stage PVDF Ultrafiltration membrane module to intercept marine sediment, plankton and algae before raw seawater enters each RO membrane element. Without complete UF pretreatment protection, the service life of seawater Reverse Osmosis membrane will be greatly shortened and bring frequent high-cost replacement work. Complete size specifications of LF-SW Reverse Osmosis membrane element and matched marine dedicated UF membrane are sorted in our water filter element.
Marine & Coastal Application Scenarios
1. Cargo ship, yacht and fishing vessel onboard compact seawater desalination unit
2. Remote offshore island resident centralized fresh water supply station
3. Offshore oil and gas platform domestic water treatment equipment
4. Marine aquaculture factory circulating water purification line
5. High-salinity underground salt well water desalination engineering project
6. Coastal resort integrated domestic water supply system
High Pressure Resistant Core Advantages Of LF-SW RO Membrane
1. Reinforced winding main body supports maximum 800psi continuous operation for Reverse Osmosis membrane
2. Constant 99.7 stable salt rejection rate for all LF-SW series Reverse Osmosis membrane element
3. Thickened hollow fiber avoids rupture under long-term high-pressure impact of this marine RO membrane filter
4. Anti-crystallization surface coating slows salt crystal accumulation on RO membrane surface
5. Complete size range covering mini 2521 to large industrial 8040 for different tonnage desalination equipment
6. Multi-stage matched Ultrafiltration membrane module provides full physical protection for the whole set of Reverse Osmosis membrane filter
