The cost-effective CERA~DUR 3 Series modules contain over 300 individual ceramic hollow fibers and a total filtration area of 1.1 m². The simple, compact design allows for several modules to be designed in series, thus reducing the overall system costs, footprint, and power consumption.
The CERA~DUR 3 Series is the perfect option for many industrial wastewater applications. In fact, for applications that don’t require process wastewater between 10° and 50° C or pH outside of 2-10 the 3 Series is a perfect fit.
Simply put, it’s the most cost-effective ceramic hollow fiber solution on the market today. Of course, it provides all the typical benefits of ceramic membranes, such as withstanding higher temperatures and a higher chemical resistance, but the advantages of implementing the CERA~DUR 3 Series don’t just end there.
The CERA~DUR 3 Series was specifically designed to be the most cost-effective ceramic hollow fiber solution for industrial wastewater applications.
- Lower capital and operating expense costs.
- Modular design options for easy installation and maintenance.
- Higher flux when compared with polymer membranes.
- Backwashed with a short cycle of water resulting in consistent high recovery.
- Able to handle aggressive wastewaters; up to 100,000 ppm TSS, 20,000 ppm COD, and 5,000 ppm oil.
Our CERA~DUR 3 Series has proven to be competitive on the industrial wastewater filtration market because it provides unmatched flexibility.
