Flue Gas Condensate Cleaning System - Power Plant Water Treatment

LiqTech standardized series of UF membrane water treatment systems suitable for cleaning of scrubber water and flue gas condensate and ensures that even the strictest discharge limits are always maintained.

The increased level of conversion from coal to biomass power plants sets new requirements for cleaning of flue gas. With a LiqTech wastewater treatment solution, we offer guaranteed filtration level 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 have 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 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.

SiC Membrane Properties

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

LiqTech ultrafiltration system for flue gas condensate cleaning in the power plant industry utilizes LiqTech’s patented silicon carbide (SiC) membranes which ensures 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.

Power Plant Scrubber Wastewater Filtration Process Liqtech

Filtration Process for Power Plants - Wet Scrubber

Our solution will treat the flue gas condensate 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 our Silicon Carbide membranes and further dewatered in a filter press, providing bulk discharge of dry waste to a waste handling station.

Flexible Installation Flue Gas Cleaning System Liqtech

Modular Design for Flexible Installation

With LiqTech’s innovative modular design, it is easy to install the flue gas cleaning system in very small areas. The solution makes it possible to further increase capacity after installation if needed.

  • Separation of filter skid for ease of installation
  • Possibility to increase capacity
  • Low maintenance
