SiC ceramic membranes provide a stabile operation even at a recovery as high as 99%*. In addition, the SiC membranes are extremely sturdy as well as temperature and chemical resistant.

3 HydraSiC HydraSiC is a standardized series of UF membrane systems suitable for cleaning of scrubber water and flue gas condensate. The HydraSiC systems which utilize LiqTech s patented silicon carbide (SiC) membranes ensures an effective and consistent retention of particles and heavy metals. SiC ceramic membranes provide a stabile operation even at a recovery as high as 99%*. In addition, the SiC membranes are extremely sturdy as well as temperature and chemical resistant. The HydraSiC series is available in various versions capable of handling flows from 0,1 m3/h to as much as 40 m3/h with options and accessaries covering any needs. The units are delivered either semi- or fully automated and all with the option of remote monitoring and control through either a VPN gateway or local SCADA integration. Multiple working hours affiliated with traditional wastewater handling at power plants and district heating facilities are hereby emancipated. The HydraSiC solution ensures that even the strictest discharge limits are maintained at all times. Furthermore, the system facilitates condensate reuse through additional treatment with an RO unit. This results in a remarkable reduction of effluent levies providing a typical return on investment in less than three years. *Contingent upon a preceding particle reducing flue gas cleaning technology (e.g. bag- or electrostatic filter) Scrubber tower at a district heating facility HydraSiC S131 membrane unit

4 HydraSiC SiC membrane systems SILICON CARBIDE (SIC) CERAMIC MEMBRANES Figure 1: Silicon carbide membranes (CoMem OD25X1178) The Heart of the LiqTech systems The SiC ceramic membrane filters and retains heavy metals and particles within the ultra-filtration range. The silicon carbide (SiC) material is extremely sturdy and resistant to abrasive media, temperatures up to 800 C and rough cleaning with aggressive and oxidizing chemicals in the ph range from O to 14 - Such conditions are solely tolerated by membranes made from SiC - in addition and due to the unique hydrophilic properties of the silicon carbide material the SiC membrane offers an outstanding high flux capacity at low pressures, requiring lesser membrane surface area per treated m 3 of water, compared to other membrane materials. Furthermore, this property allows the LiqTech SiC membrane systems to consume considerably less energy - Thus the SiC membrane is in its element when filtering flue gas condensate and waste water from power, CHP and district heating plants. OBVIOUS ECONOMICAL AND ENVIRONMENTAL ADVANTAGES A LiqTech solution based on UF and RO membrane technology treats the condensate to a quality which may be used as make-up water in the transmission grid. This means that your district heating facility no longer has to pay expenses affiliated with effluent levies and, in addition, saving money for purchasing and refilling of potable (drinking water) as make-up water in the district heating pipes. Without the use of polymers - Protecting the environment! Figure 3: Flue gas condensate (left) and SiC UF cleaned condensate
