2 INTRODUCTION J.K. BACKGROUND AREAS OF CONSULTING SERVICES Water Supply Wastewater Disposal Storm Drainage Management Groundwater Development Land Development SCOPE OF CONSULTING SERVICES Preliminary Investigations Feasibility Studies Detailed Design Construction Services Post-Construction Services EQUIPMENT SUPPLY Water Treatment Package Systems Wastewater Treatment Package Systems Water Well Operation Monitoring APPLIED RESEARCH AND DEVELOPMENT Water Treatment Systems Wastewater Treatment systems Water Well Monitoring Systems

3 WATER / WASTEWATER SUPER OXIDATION, COAGULATION AND FLOCCULATION SYSTEM SYSTEM COMPONENTS OXIDATION Aeration Oxidation with O 3 Super Oxidation with O 3 & H 2 O 2 COAGULATION & FLOCCULATION Independent Coagulation Ozonation & Coagulation Combined FILTRATION One-Stage Filtration Two-Stage Filtration

4 OXIDATION SYSTEM SYSTEM COMPONENTS Oxidation Tank Circulating Pump Air Aspirator-Mixer Ozone Generation Off Gas Destruct Unit Effluent Syphon Breaker HOW THE SYSTEM OPERATES SYSTEM UNIQUE FEATURES Flexible Oxidation Flow Rates Independent of Inlet Water Flow Rate Ozone Supply Under Vacuum Thorough Mixing of Oxygen and Water Single or Multiple Recirculation of Water through the Oxidation System SYSTEM APPLICATIONS Aeration of Water for Removal of H 2 S, CO 2, Ammonia, Odour Control Ozonation of Water as Pre-Oxidation, for one Treatment Processes for Removal of Algae, Colour, Turbidity, Fe, Mn, H 2 S Aeration for Wastewater for Biological Treatment in Secondary Tertiary Treatment Processes Ozonation of Municipal Wastewater Effluent for Disinfection Super Oxidation for Removal of Difficult to Oxidize Industrial Pollutants Super Oxidation of Treated Water for Reduction of Dissolved Organic Carbon Prior to Chlorination

5 OXIDATION, COAGULATION AND FLOCCULATION ALTERNATIVE 1 INDEPENDENT COAGULATION SYSTEM Independent Control of Ozonation and Coagulation Processes. Oxidation Options; Ozonation alone or Ozone & H 2 O 2 Superoxidation Wide Range of Applications in Water and Wastewater Treatment for Municipal & Industrial Uses Treatment of Water with High Content of Naturally Occuring Organic Compounds and Associated Colour, Giardia, Cryptosporidium Treatment of Water with Industrial Pollution, Chlorinated Organics, Trihalomethanes, Hydrocarbons

6 OXIDATION, COAGULATION AND FLOCCULATION ALTERNATIVE 2 COMBINED COAGULATION & OXIDATION PROCESS Compact & Economic Design Applications similar to those of Alternative 1 Oxidation Options; Ozonation alone or Ozone & H 2 O 2 Superoxidation

7 OXIDATION, COAGULATION, FLOCCULATION AND FILTRATION SYSTEM ALTERNATIVE 1 OXIDATION, COAGULATION, FLOCCULATION WITH ONE-STAGE FILTRATION Novel Filtration System with Syphon Operation Simple Control of Operation Filter Bed Surface can not be Exposed & Disturbed High Hydraulic Head in Low Filter Vessel Wide Range of Application for Removal of Suspended Matter; Natural Turbidity of Clay, Silt, Organics, and Oxidized Particles

8 OXIDATION, COAGULATION, FLOCCULATION AND FILTRATION SYSTEM ALTERNATIVE 2 OXIDATION, COAGULATION, FLOCCULATION WITH TWO-STAGE FILTRATION Novel Filtration System with Syphon Operation and Two-Stage Filtration in one Vessel Compact & Economic System Low Headroom Requirements Backwash Water Saving, both Filter Stages can be Backwashed at the same time or independently as required Filtration Options: Roughing Filter & Polishing Filter Turbidity Removal & Adsorption Filter of GAC or other Proprietary Filter Media
