Filtration Systems for Wet Gas Scrubber Water and Flue Gas Cleaning

LiqTech Water offers an innovative and superior water treatment system ideal for power plants' water treatment processes, such as filtration of wet gas scrubber water and flue gas condensate. The system ensures that even the strictest discharge limits are always maintained and condensate reuse for a more cost-efficient operation.

Today, more power plants convert from coal to biomass. With this conversion comes new requirements for cleaning flue gas and wet gas scrubber water, which ultimately calls for superior power plant water treatment solutions. With a LiqTech power plant water treatment system, you are guaranteed filtration levels under the most extreme conditions without using polymers.

The LiqTech solution is based on patented, state-of-the-art ultrafiltration membranes. The water treatment system is suitable for cleaning wet gas scrubber water and flue gas condensate to comply with authority requirements for limit values on heavy metals and other particulate matters.

Moreover, the system facilities condensate reuse through additional treatment with reverse osmosis (RO) unit. This results in a remarkable reduction in waste-handling costs, providing a typical return on investment in less than three years. On top of this, multiple working hours are emancipated on traditional wastewater handling at power plants and district heating facilities.

SiC Ceramic Membrane Properties

Our revolutionary ceramic silicon carbide membranes will provide you with a reliable and future-proof industrial water treatment solution for flue gas condensate and wet gas scrubber water.

Our flue gas cleaning technology for the power plant industry utilizes our patented silicon carbide (SiC) ceramic membranes, ensuring effective and consistent retention of particles, particulate matter, and heavy metals. SiC ceramic membranes provide stable operation even at a recovery typically as high as ≤95%. The SiC membranes are highly sturdy and thermal and chemical resistant, making them ideal for harsh industrial applications required by wet gas scrubber water and flue gas condensate.
Ultrafiltration (UF) membrane technology is based on pure mechanical retention of unwanted particles. This means that 100% of the wastewater volume is filtered by the membranes, providing consistent water quality of the treated water.

Membrane technology delivers a much more efficient removal of particles than conventional technologies like sand filters and adsorption filters due to the membranes' porosity being approx. 100 times closer than the media composition in, e.g., a sand filter.

As the superior filtration properties deliver high-quality treated water, consecutive water treatment processes such as NF, RO, EDI, UV, etc., have significantly improved operating conditions – typically with reduced operating costs.

Power Plant Scrubber Wastewater Filtration Process Liqtech

Filtration Process for Wet Gas Scrubbers and Flue Gas Condensate

Our flue gas cleaning technology will treat the flue gas condensate or wet gas scrubber water from the scrubber tower, and then it is sent back for reuse via RO or discharge. The metal loads and particulate matters are filtered and concentrated in the silicon carbide membranes and further dewatered in a filter press, providing bulk discharge of dry waste to a waste handling station.
