2 Porifera IntroducTon and Overview Founded in 2009 in Hayward, CA, USA. Porifera Forward Osmosis (PFO) technology developed for US military PFO systems for product concentraton, near ZLD, and water reuse Sold elements and pilot systems in Europe, Middle East, Australia & the Americas since November 2013 product launch. Mass manufacture membrane in Korea; systems in US Water PFO modules Energy At the Heart of the Water- Energy- Food Nexus PFO- 100 element (7m 2 ) PFO module (42-70 m 2 ) ,000 gpd PFO pilot system (20-40 m3/day) (with two 42 m 2 modules) 2

3 What are the perceived challenges for FO? 1) FO Membrane performance: Cost and footprint 2) Draw chemistry & recovery: Energy use Clean Water Feed WATER (through PFO by osmosis) Concentrated Draw FO Membrane Draw Recovery Dilute Draw Concentrate 3

4 Perceived Challenges þ Check these off your list!!!! 1) FO Membrane performance: Cost and footprint 2) Draw chemistry & recovery: Energy use Over 10 pilot size systems opera?ng successfully worldwide that can compete on cost, footprint & energy use RO 4

5 Key Remaining Challenges are Market Based What is FO good for? Is FO ready for broad commercializaton? What are FO Target markets? Customer operated pilot in Asia 5

6 What does FO do beeer than other technologies? Oil Field Waste Conc. 4X 14 X Concentrated RO Brine with Silica Tomato Juice to Tomato Paste HIGH FOULING - Fewer treatment steps and a new tool to solve difficult problems HIGH QUALITY - Unprecedented retenton of flavors, VOC s, and PATHOGENS/VIRUS HIGH TDS - Concentrate up to 200,000 ppm TDS at >70% energy & cost savings 6

7 For Which Industries is FO a Good Fit? FOOD & BEVERAGE OIL & GAS CHEMICAL INDUSTRY WATER FOOD & BEVERAGE CONSUMER PRODUCTS F&B PROCESSING Product SUSTAINABILITY: ConcentraTon WATER Waste &WASTE ConcentraTon & Reuse Water Recycling OIL & GAS ENHANCED OIL RECOVERY Unique WASTE drilling CONCENTRATION fluid chemistry and reuse WATER REUSE ZLD concentraton of oilfield brines Small footprint offshore treatment INDUSTRY & MINING PRODUCT CONCENTRATION Product concentraton High purity processing Waste concentraton and reuse WATER & AGRICULTURE INDUSTRIAL WATER REUSE MUNICIPAL WATER REUSE DESALINATION UlTmate technology for potable reuse Unique water reuse solutons for every aspect of society. Why consider FO? New products, low cost, sustainability, & higher purity Why consider FO? High temperatures, reliability, low cost, small footprint Why consider FO? High temperatures, new products, low cost, small footprint Why consider FO? Purity for POTABLE, IRRIGATION, & RESDIDENTIAL REUSE 7
