Benefits of Using Ceramic Membranes for Industrial Wastewater Applications 

There are several membrane filtration technologies available on the market for industrial wastewater treatment.  Most of the membranes available on the market today have a polymeric barrier, but ceramic membranes are becoming more readily available for many Industrial Wastewater applications.

Membrane selection for industrial Wastewater applications can primarily be determined by the characteristics of the wastewater to be treated as well as the overall water quality parameters that are required.  Ceramic membranes have proven to be extremely beneficial in applications that have very demanding conditions which would typically foul polymeric membranes and limit their overall effectiveness. 

Why Ceramic Membranes vs Polymeric Membranes

Ceramic membranes can deliver the required porosity expected for micro-filtration/ultra-filtration whilst also proving to be durable with a high resistance to degradation by a wide range of chemicals and chemical concentrations.  This allows for more aggressive chemical cleaning procedures. 

With regards to overall durability, depending on the application, ceramic membranes have proven life cycles in excess of 15 years and have also proven to feature high temperature and pressure tolerance.

Other inherent benefits of ceramic membranes over polymeric membranes are:

  • Typically deliver higher flux than polymeric membranes.
  • Lower TMP for a given flux.
  • Ability to tolerate higher cross flow velocities which allows for extended process runs.
  • Proven durability with handling high pressure, temperature, and chemical inputs.
  • Ceramic membranes do not need to stay wet like polymeric membranes, they can be drained, removed from use and restarted easily after being out of service

 

Features of the CERA~DUR ceramic hollow fiber membranes 

Our CERA~DUR, Ceramic hollow fiber designs have a high packing density and uniformed spacing of the fibers.  This enables the filtration of large volumes of wastewater utilizing a minimal amount of space.

The CERA~DUR Ceramic membranes facilitate filtration at higher temperatures, with greater chemical resistance, and at broader pH levels These ceramic membranes are heavy duty and are very capable of handling high amounts of aggressive solids, organics, and emulsified oils.

Crossflow in-out filtration ensures long operating cycles with a low fouling risk or the buildup of materials on the surface on the membranes. Fouling can eventually lead to degradation in the quality of the permeate water, resulting in trouble meeting disposable waste requirements.   

Our Ceramic hollow fiber membranes are available in different pore sizes, demonstrated by the four size options we offer with our CERA~DUR technology. In order to suit specific filtration needs, options range from nanofiltration to microfiltration. The CERA~DUR Ceramic hollow fiber technology can also be used as a pre-treatment to both nanofiltration and reverse osmosis.
