CPI-1030 UF Module LITREE Equivalent

Product Introduction

The CPI-1030 UF Module is a high-performance ultrafiltration membrane unit engineered to serve as a direct replacement for the LITREE CPI-1030 module. Designed for municipal, industrial, and commercial water treatment systems, this module is built around hydrophilic PVDF (polyvinylidene fluoride) hollow fiber membranes that provide outstanding mechanical strength, superior chemical resistance, and long-lasting filtration performance.

Fully compatible with the LITREE CPI-1030 in both form and function, this UF module offers easy integration into existing systems without retrofitting, ensuring a seamless transition while improving water quality and operational efficiency.

Working Principle

The CPI-1030 UF Module operates using the outside-in hollow fiber ultrafiltration method. It filters contaminants from feedwater by physically blocking particles larger than the membrane's pore size.

Filtration Process Overview:

1.    Feedwater enters the outside of the hollow fibers (shell side).

2.    Water permeates through the membrane wall, leaving behind particles, bacteria, and other suspended solids.

3.    Purified water collects inside the hollow fibers (lumen) and is directed to the permeate outlet.

4.    Regular backwashing and air scouring help dislodge accumulated foulants and maintain performance.

This physical separation process ensures a stable supply of high-quality water, even in the presence of challenging feedwater conditions.

FAQ

1. Is this module 100% compatible with the LITREE CPI-1030?

Yes, the CPI-1030 UF module matches the size, membrane area, and hydraulic connections of the original LITREE model, ensuring easy replacement.

2. What does this UF module remove from water?

It removes suspended solids, bacteria, algae, viruses, colloids, and other impurities down to 0.03 μm in size. However, it does not remove dissolved salts or organics.

3. How often should the module be cleaned?

Routine backwash and air scour should be conducted every 30–60 minutes. Chemical cleaning (CIP) is recommended every 2–4 weeks, depending on fouling rates.

4. What is the typical lifespan of the CPI-1030 UF Module?

With proper operation and maintenance, the membrane can last between 5 to 7 years.

5. Can this module handle high-turbidity water?

Yes, but pre-filtration (such as sand filters or cartridge filters) is recommended when feedwater turbidity exceeds 100 NTU.

6. What chemicals can be used for cleaning the membrane?

CIP protocols typically include sodium hypochlorite (oxidative cleaning), citric acid (scale removal), and sodium hydroxide (organic removal), within the safe pH range of 2–12.

7. What’s the optimal operating pressure for this module?

The ideal operating pressure is 0.1–0.2 MPa (1–2 bar), ensuring efficient filtration without exceeding transmembrane pressure limits.

8. Can the module be used in high-temperature environments?

The module operates safely up to 45°C. For temperatures above this, consult the manufacturer for compatibility and performance guarantees.

Conclusion

The CPI-1030 UF Module offers a superior, cost-effective, and fully compatible alternative to the LITREE CPI-1030. Whether you’re operating a large municipal facility or a compact industrial unit, this UF module ensures optimal performance, long service life, and excellent water quality.

With simple installation, easy maintenance, and a proven track record of reliability, the CPI-1030 is a smart upgrade for any system utilizing ultrafiltration technology. Its robust PVDF membrane structure ensures durability, while its high permeability and consistent filtrate quality make it a top choice for engineers and system integrators alike.
