CUF|Shield Ceramic Membranes | Advanced Water Treatment for Municipal & Industrial Needs
CUF|Shield™ Engineered for Performance, Built for the Future
Transforming Water Treatment for Municipal and Industrial Needs
Water is one of the most valuable resources in the world, and ensuring its purity, availability, and sustainability is more critical than ever. CUF|Shield™, previously known as CM-151, is an advanced ceramic membrane technology designed for high-performance water treatment. It is engineered for municipal drinking water and waste water, as well as industrial process water and wastewater treatment.
Designed for long-term reliability and operational efficiency, CUF|Shield™ provides a cost-effective, high-performance alternative to traditional polymeric membranes, reducing downtime, energy consumption, and maintenance costs.

Why CUF|Shield™?

Same Trusted Technology: CM-151 is Now CUF|Shield™
Water treatment challenges are evolving, and reliable, high-performance solutions are essential. CUF|Shield™ is engineered with advanced ceramic membrane technology that provides:
- Superior filtration performance: With a nominal pore size of 30 nm, CUF|Shield™ captures suspended solids, bacteria, and pathogens to deliver exceptionally pure water.
- Unmatched durability: Crafted from proprietary hydrophilic ceramic materials, our membranes are designed to withstand extreme conditions, resist fouling, and last up to six times longer than traditional polymeric membranes.
- Energy efficiency: Our patented segmented monolith design optimizes water flow and minimizes pressure drops, reducing energy consumption and operational costs.
- Seamless integration: The modular design of CUF|Shield™ allows for easy retrofitting into existing water treatment systems and compatibility with a wide range of pre-treatment processes.
Built to make a real difference

Municipal Water Treatment Applications
CUF|Shield™ (CM-151) supports municipalities in delivering safe, clean water and promoting sustainable water use:
- Drinking Water Treatment: CUF|Shield™ (CM-151) guarantees high-quality drinking water by effectively filtering out suspended solids, pathogens, and harmful microorganisms. It helps municipalities comply with stringent drinking water standards while minimizing maintenance costs and maximizing system lifespan.
- Wastewater Discharge Compliance: This filtration system ensures that treated wastewater meets environmental discharge regulations, reducing pollutants and protecting ecosystems. CUF|Shield’s™ (CM-151) efficiency supports continuous operation with minimal operator intervention.
- Wastewater Reuse: Enables municipal water reuse for applications like irrigation, street cleaning, and industrial supply. CUF|Shield™ (CM-151) plays a key role in circular water management, helping cities conserve resources and reduce reliance on freshwater sources.
- Seawater Desalination Pre-Treatment: Ideal for desalination plants, CUF|Shield™ (CM-151) acts as a pre-filtration barrier protecting reverse osmosis membranes by reducing fouling and improving overall energy efficiency.

Industrial and Mining Water Treatment
CUF|Shield is engineered to withstand harsh industrial environments, offering consistent filtration performance in mining operations, factories, and heavy industries:
