Wet Gas Scrubber Cleaning System

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 any use of 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 spend on traditional wastewater handling at power plants and district heating facilities are emancipated.

The LiqTech flue gas and wet gas scrubber cleaning system require minimal maintenance and a built-in Cleaning-In-Place (CIP). It is possible to integrate backflush, precipitation, pre-treatment, remote monitoring, and control via an internet connection, etc. If needed, LiqTech Water offers other turnkey water treatment installations such as reverse osmosis (RO), nanofiltration (NF), carbon filter (GAC), and several other relevant technologies depending on your specific requirements.

• Clean and reuse your condensate
• Minimize your water consumption
• Minimal maintenance
• Guaranteed consistently high-quality water
• Compliance with even the strictest discharge limits
• Market-proven solution
• Future-proof solution
• Remote service & support 24/7 – anywhere in the world

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, which makes 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.
