1 NEW GENERATION MEMBRANES clean water for life

2 CEMBRANE introduction: Manufacture Silicon Carbide (SiC) Ceramic MF/UF membranes Production facility in Denmark Sell to OEM/Integrated Solutions providers Patented membrane technology We produce and develop a new generation SiC ceramic membrane from our facility in Denmark. We provide OEMs & System integrators in more than 20 countries with a unique outside-in flat sheet membrane and module to treat challenging drinking- and waste waters

3 FIELDS OF application: Our SiC flat sheet membranes are being deployed in a wide variety of applications: MBR Food & Beverage Pharma Textile Sewage & sludge thickening Household MBR in food & beverage Pre-RO >100 LMH gross flux INDUSTRIAL WASTE WATER REUSE Mining - Heavy metal removal Semiconductor (OVIVO) - Wastewater reuse Scrubber wastewater - Removal of hydrocarbons and TSS to meet discharge requirements PetroChemical - Reuse of high strength organic wastewater Drinking water installation in Sweden 575 LMH peak flux PRODUCED WATER TREATMENT Pre-RO treatment of flowback water for surface discharge or reuse Recovery of RO brine with Lime Softening + SiC filtration Produced water installation in US DRINKING WATER Ground water treatment - Removal of Fe, Mn, As, Ra. Sea Water desalination Pre-treatment to RO - Removal of Algae, TOC & TEP Surface water treatment - Removal of turbidity, micro-organism and Arsenic Containerized solution for drinking water, with flux 500 LMH

4 TECHNOLOGY KEY FEATURES ceramic is not just ceramics: Our membrane and substrate are produced from Silicon Carbide (SiC) on a flat sheet structure. This gives our membrane some unique advantages: KEY HIGHLIGHTS OF CEMBRANE: 0.1 µm pore size Highly assymetric structure Outside-in filtration direction Submerged vacuum/gravity driven Double sided filtered water outlet for high flux operation Self-degassing due to filtered water outlet at the top of end-cap Filter active layer on the outside of the membrane plate 0.1 mm Membrane body (substrate) with very large pore size 8 mm HYDROPHILIC MEMBRANE SURFACE: A membranes contact angle to water is an accurate measure of how hydrophilic a membrane is. The more hydrophilic the membrane surface the higher the operating flux rate. Achieved benefits using Cembrane: 3-10x the flux compared to polymeric Unmatched low footprint Low pressure operation at high flow High recovery rates Applicable for high sludge concentration 15,000 LMH/bar clean water permeability up to 160 m3/day pr. m2 (MBR) / 1100 m3/day pr. m2 (Drinking Water) bar more than 99% (Drinking water) can operate in concentrations of 4% organic waste & 10% inorganic waste Very hydrophilic Less hydrophilic SIC ALUMINA OXIDE PES UF CELLULOSE UF PCTE MF POLYARAMIDE UF PVDF UF Water droplet contact angel o Up to 150 LMH in MBR & 900 LMH in Drinking water Source: 1.

5 CHEMICALLY INERT MEMBRANE MATERIAL: Silicon Carbide has complete chemical resistance. This provides a range of benefits in various applications: Can operate in extreme environments - ph 1-14 Extremely durable & reliable operation Fast and easy restoring of permeability High resistance to oxidants even ozone CORROSIVE WEIGHT LOSS [MG/CM2/YR] TEST ENVIRONMENT (WT%) SiC Alumina Oxide Si composites Tungsten carbide 98% 100 o C % 100 o C % 70 o C 72 0, % 100 o C % 100 o C 7 0,5 85% 100 o C 8, % 25 o C 20 7,9 8 Source: Corrosion prevention and protection Sastri et al. LOW FOULING POTENTIAL ON CEMBRANE S MEMBRANE SURFACE: Due to the negative charge of the membrane surface on a wide ph range, the membrane is less prone to fouling and clogging and allows for less maintenance equirement.

Most compact installation due to frameless rack design. Easy tower assembly due to simple key lock connection. Lift or removal option for single towers(remaining towers stay in opera on). Integrated double sprinkler line for enhanced cake layer removal and chemical spray. Header system with option of direct injection of chemicals into header collector or connection of additional instrumentation.

7 INSTALLATION flow diagram of operation Below flow diagram illustrates the required equipment to operate the technology to its fullest. The membranes can run without pumps, merely on gravity and air-scouring. But to reach its peak performance, we recommend designing with options as illustrated below. High pressure backpulse for fast permeability recovery Integrated on-air membrane tower wash-down for removal of sticky sludge and debris trapped between membranes and towers Integrated on-air chemical cleaning from the outside instead of regular CEB. This cleaning option requires less than 1/10 the chemical volume. Membrane towers are densely packed in tank for all applications providing small footprint Flow through the membrane towers of feed water provides an even concentration throughout the tower and complete discharge of sludge accumulations between membrane units during backwash and relaxation mode De-gassing line Flow through of concentrate to pre-treatment (Used in MBR and high TSS applications) Blower Filtration Pump Filtered water Feed inlet Angled floor for effective waste discharge Sprinkler Pump Backwash Tank Membrane Tank Compact design regardless of application Backwash Pump Chemical Pump Waste outlet
