LiqTech International, Inc. announces a new ceramic flat sheet membrane product

LiqTech International, Inc. is pleased to announce the launch of a new state-of-the-art silicon carbide (SiC) flat sheet membrane disc for membrane bioreactors and moving bed bioreactors (MBBRs) for wastewater treatment.

The flat sheet membrane (FSM) uses the outside-in filtration principle. This allows either a pressurised mode or a vacuum suction mode of operation which reduces the cost of installation. The FSM module is submerged in a tank containing dirty water and by applying moderate suction pressure, clean water is produced. This configuration is mainly used in modern MBR and MBBR wastewater treatment systems and reduces the strain on housings, pumps and controls.

With this new expansion of the product portfolio, LiqTech is able to cover a wider spectrum of the market. The LiqTech tubular filter is suited for low-solid content feeds, while the FSM is better suited for higher solid content applications, and the rotating discs target very high solid content feeds.

The high clean-water permeability of the SiC material, being around 20 times more permeable than conventional polymeric 0.1μm UF membranes and four times more permeable than α-Al2O3 0.1μm UF membranes (competing ceramic material), allows compact systems that save footprint for customers.

The FSM targets the MBR and MBBR wastewater treatment market which is among the most important applications in technology. The MBR market reached a size of about US $800 million in 2011 and is expected to grow at approximately 20% per year to exceed $3 billion in 2018.
