Flue Gas Condensate Cleaning System

The increased level of conversion from coal to biomass power plants sets new requirements for the cleaning of flue gas. With a LiqTech wastewater treatment solution, we offer guaranteed filtration levels under the most extreme conditions – without any use of polymers.

LiqTech’s ultrafiltration membrane water treatment system is suitable for cleaning of scrubber water and flue gas condensate in order to comply with authority requirements for limit values for heavy metals and other particulate matters.

Turnkey water treatment solutions for power plants

LiqTech’s wastewater treatment for power plants is available in various versions capable of handling flows from 0,1 m³/h to as much as 1000 m³/h with options and accessories covering any needs. The LiqTech industrial wastewater system requires only minimal maintenance and has a built-in Cleaning-In-Place (CIP), as well as the possibility of integration of backflush, precipitation, pre-treatment, and with the option of remote monitoring and control via an internet connection, etc. If needed, LiqTech offers turnkey installations consisting of other water treatment technologies such as reverse osmosis (RO), nanofiltration (NF), carbon filter (GAC), and several other relevant technologies depending on your specific requirements.

The industrial water treatment solution ensures that even the strictest discharge limits are always maintained. Furthermore, the system facilitates condensate reuse through additional treatment with a RO unit. This results in a remarkable reduction of effluent levies providing a typical return on investment in less than three years.

Multiple working hours affiliated with traditional wastewater handling at power plants and district heating facilities are hereby emancipated.

LiqTech ultrafiltration system for flue gas condensate cleaning in the power plant industry utilizes LiqTech’s patented silicon carbide (SiC) ceramic membranes which ensure effective and consistent retention of particles and heavy metals. SiC ceramic membranes provide stable operation even at a recovery typically as high as ≤95%. In addition, the SiC membranes are extremely sturdy as well as temperature and chemical resistant.

Ultrafiltration (UF) membrane technology is based on pure mechanical retention of unwanted particles, which means that 100% of the wastewater volume is filtered/treated by the membrane, 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 porosity of the membranes being approx. 100 times closer than the media composition in e.g. a sand filter.

The superior filtration properties resulting in quality treated water means that subsequent water treatment such as NF, RO, EDI, UV, etc. have clearly better operating conditions - typically with reduced operating costs.
