Upgrade & Expansion of Existing ETPs at Pulp & Paper Mills Marc Krieger IPPTA Conference – Kashipur December, 2015 Director of Business Development – Asia-Pacific

Proprietary and confidential Increase of ETP capacity as a result of expansion of production activity in the mill  Increased production capacity  Additional production lines Improve effluent quality :  Reduce BOD, COD  Nitrification / de-nitrification (NH 4, TN)  Color reduction  ZLD implementation Problem Definition – When is ETP Upgrade / Expansion Required

Proprietary and confidential Main Challenges in ETP Upgrade / Expansion Technology upgrade to ensure meeting stricter compliance requirements Maximum utilization of existing infrastructure and ETP components : aeration tanks, clarifiers, air blowers, etc. Minimize the need for additional land allocation and civil works Minimize CAPEX

4 Proprietary and Confidential Traditional Solutions for Effluent Treatment - General  Low O&M cost  Simple to operate  Low effluent quality  Operation problems (odors)  Long SRT days = large area Extensive Oxidation pondsAttached GrowthSuspended Growth  Simple to operate  Resistant to shock loads (flow, toxicity)  Small footprint  Lower effluent quality  Simple process control  Operational problems (odors, clogging)  Good treatment  More space required  Complex operation / process control  Less resistant to shocks (load, toxicity) Intensive

Proprietary and confidential MBBR – Moving Bed Bi-Reactor Provides the process advantages of fixed film while eliminating the disadvantages, and enables achieving superior effluent quality Proven technology in the pulp & paper sector Increase of ETP capacity - in the range of % - when converting ASP to MBBR, or implementing MBBR before existing ASP Advantages of Biomass Carrier Technologies - MBBR

Proprietary and confidential Advantages of Biomass Carrier Technologies - MBBR Maximum design flexibility in upgrade / expansion of existing ETPs Maximum utilization of existing tanks = minimum requirement for additional footprint and civil works Simple & fast implementation : in most cases ETP operates throughout the upgrade works Staged investment : in “real time”, parallel to actual increase in mill capacity

Proprietary and confidential Recycled, high-density polyethylene Highly open external design > 650 m 2 /m 3 Effective surface area Optimal oxygen and nutrients transfer Applicable for various biological processes Aqwise Biomass Carriers protect biofilm against abrasion, ensures mass transfer efficiency and prevent clogging Innovation That Works

Proprietary and confidential  High effective surface area for biofilm growth : 650 m 2 /m 3  Openings in outer circumference create turbulent flow within the carrier, and minimize distance to biofilm from to mm across the entire media  10 year guarantee for mechanical integrity of the carrier, MoC : HDPE  Same media for all process stages Aqwise Biomass Carriers – Advantages to Remember

Proprietary and confidential High loadMedium load Aqwise Biomass Carriers - ABC Low load

Proprietary and confidential Color – typically in pulp mills  Originates from lignins in natural raw materials (wood chips), or from dyes (colored tissue paper)  Not completely bio-degradable – residual color after the biological stage  Requires additional physico-chemical treatment stage after the biological reactor : clari-flocculator, DAF Hardness  Originating from calcium-based chemicals used in the paper making process  Potential for precipitation on the carriers – scaling. Will impact carrier weight / mixing

20 Proprietary and Confidential Proprietary and confidential What Everyone Wants to Know – How Much Does it Cost ??? And, of course, there is no “simple” answer. Will be determined case by case based on :  Effluent characteristics : flow & quality  Effluent quality requirements : discharge to environment, ZLD, irrigation  Existing ETP infrastructure : technology, age, level of operation & maintenance
