Hybrid membranes are a relatively new approach to manufacture new and more durable membranes for water and wastewater treatment. Opposite of one-component membranes, hybrid membranes are produced of several materials to equip them with improved properties. This ultimately leads to improved performance, delivering enhanced permeate quality. The HTM can, in some cases, achieve filtration processes that are simply impossible by conventional filtration technologies. With this innovative technology, securing clean water in a durable and cost-efficient manner is no longer a complex process.

Hybrid membranes can either be produced of polymers or ceramics. Polymeric membranes have previously been widespread due to their low manufacturing costs and easy scalability. Yet, polymer membranes lack thermal, chemical, and mechanical strength, making them incapable of handling aggressive fluids from arduous industries, such as marine, power plants, and oil and gas. Moreover, they cannot withstand frequent chemical cleaning, which is crucial to maintain an efficient and hygienic liquid filtration process. Due to these significant drawbacks of polymer membranes, ceramic membranes offer the most durable separation processes and can take the lead in cleaning some of the world’s most polluting industries.

Filtration of the Future

Based on more than 20 years of experience in developing and producing proprietary membrane products, we have developed a ceramic hybrid membrane. The hybrid technology membrane combines the materials silicon carbide (SiC) and zirconia (ZrO2).

The aim of using these two materials is to include the best attributes of each material. The carrier of the HTM is made of SiC, which is one of the hardest materials in the world. This ensures durable and long-lasting support. The coating layer comprises monoclinic zirconia, ensuring a well-defined selectivity within the ultrafiltration (UF) range. The HTM membrane has a pore size of 60 nanometers.

Why use ceramic membranes - LiqTech CeramicsBoth silicon carbide and zirconia are chemically resistant, enabling the HTM to operate with all kinds of fluids from pH 0-14 without compromising on permeate quality.

Moreover, the HTM membrane has a long lifetime, ensuring that your filtration application can go on and on without you worrying about membrane replacement costs. It is a low-pressure technology with an unmatched flux, delivering cost-efficient and durable separation processes.

The HTM operates in crossflow mode, which also works as a rinsing mechanism to ensure minimal solids build-up to avoid fouling. It is a pressure-driven technology, meaning that no chemicals are needed for operations. Chemicals are only employed for chemical Cleaning-in-Place (CIP), making the HTM a clean technology of the future.

The HTM can both be used as pre- and post-treatment.

The hybrid membrane can be utilized in multiple industries, including:

  • Drinking water treatment
  • Industrial wastewater
  • Food and beverages
  • Cosmetics
  • Pharmaceutical
  • Agro industries
  • Pre-RO filtration
  • … and much more

The HTM membrane can be made in customized geometries, making it adaptable to your specific filtration needs.

Ideal Water Resources Management

Only 3 % of the water on earth is safe for humans to consume. Simultaneously, the global population continues to grow, stressing the need for clean water. Hybrid membranes are an efficient and cost-effective means to manage our scarce water resources with care and respect. But water resources management is not just essential to secure clean potable water across all parts of society. It is simply good business. Once you manage your water resources most optimally, there are significant related savings. Rather than discharging water and treat it as waste, you can reclaim it and treat it as an asset.
