6. Working Principle

The LFUF-10 utilizes ultrafiltration (UF) technology to separate contaminants via semi-permeable membranes:

1. Pre-Treatment:

• Sand Filtration: Removes suspended solids (particles >50 μm).

• Activated Carbon Adsorption: Eliminates chlorine, organic matter, and odors.

• Anti-Scale Dosing: Inhibits scaling from calcium and silica.

2. Membrane Filtration:

• Feedwater is driven through hollow-fiber membranes under low pressure.

• Pure water (permeate) passes through membrane pores, while contaminants are retained.

3. Backwashing:

• Automated reverse flow cleans membranes, restoring flux and preventing fouling.

4. Output:

• Permeate: High-quality water directed to storage or downstream processes.

• Concentrate: Periodic discharge of concentrated contaminants.
