LH3-0660-V UF Module LITREE Equivalent

Product Introduction

The LH3-0660-V UF Module is an industrial-grade ultrafiltration membrane product designed as a high-performance replacement for the LITREE LH3-0660-V module. With cutting-edge PVDF hollow fiber membrane technology and robust engineering, this module delivers excellent filtration efficiency, mechanical durability, and chemical resistance, making it an ideal choice for diverse water and wastewater treatment applications.

Compatible with standard LITREE configurations, the LH3-0660-V is engineered for drop-in replacement, offering end-users a cost-effective solution without the need to modify existing systems. This ultrafiltration module is designed for applications requiring high-quality permeate with low turbidity and pathogen removal.

Working Principle

The LH3-0660-V module operates on the outside-in hollow fiber ultrafiltration principle, utilizing a physical barrier to remove contaminants through membrane pores with a nominal size of 0.03 microns.

Filtration Process Overview:

1.    Feedwater Entry:
Untreated or pre-filtered water enters the module shell and surrounds the hollow fiber membranes.

2.    Separation by Pore Size:
Water is forced by pressure through the outer membrane surface into the hollow fiber's core. Suspended solids, bacteria, algae, and high molecular weight organics are rejected.

3.    Collection of Permeate:
Clean water exits through the center of the fibers and flows out via the permeate outlet.

4.    Backwashing & Cleaning:
Periodic backflushing and chemical cleaning help dislodge fouling material and maintain membrane flux over time.

The LH3-0660-V achieves high removal rates of particulate and microbial contaminants while maintaining high flux and low transmembrane pressure.
