3 High Level Disinfection Regulatory differs from State to State General Trends Filtered effluent Less than 2.2 MPN/100 ml total coliform 4 of 7 samples Non detectable concentrations for Fecal coliform 5 Title 22 Requirements Filtered wastewater has been disinfected by either a. Chlorine Chlorination To Reuse b. Other Disinfection Process Min CT = 450 mg-min/l Min Contact time = 90 min 5-log removal of poliovirus Process X To Reuse 6 3

4 Conditional Acceptance Process for evaluation of technologies in California Chlorine 450 mg-min/l based on 90 minute modal contact time and 5 mg/l residual Other disinfection technologies tested to validate performance for 5 log removal of polio-virus 7 Factors that Impact Disinfection Process Mechanical Electrical I&C Flow Effluent quality: Solids Amount, size, type Ammonia Impact Chlorine and a UV absorber Residual COD pass through Non-biodegradable fraction Color additional chlorine demand/uv absorber Iron additional requirements/o&m/replacement of feed lines Hardness O&M/replacement of feed lines Transmittance UV spectra 8 4

5 What Disinfectant Do I choose for High Level Disinfection? Chemical Chlorine Gas Hypochlorite Liquid On-site Generation Chlorine Dioxide Chloramines UV Emerging Ozone, Pulsed UV PAA, Ferrate Peroxide, BDCMH 9 CONDITIONALLY APPROVED TECHNOLOGIES 10 5

6 Chlorine Disinfection Alternatives Chlorine Gas Sodium Hypochlorite (liquid) On-site generation of Hypochlorite On-site generation of Chlorine Gas Chlorine dioxide 11 Most common approach for reuse applications 1 pound of chlorine = 1 gallon of Hypochlorite at 12.5% solution. Storage Tank, Pump, and Contact Basin 450 mg-min/l based on 90 minute modal contact time and 5 mg/l residual. Requirements vary from State to State. Work being completed by Soroushian etal is indicating that ct might be able to be decreased to 100 mg-min/l using free chlorine Hypochlorite 12 6

7 On-site Generation of Hypochlorite Raw Materials Salt Electricity Water Generates 0.8% - 15% hypochlorite solution Survey of Facilities Few WW facilities All primary disinfection Other applications include Filament control Odor control Limited use in reuse applications interest increasing 13 CHEMISTRY AND MIXING ARE CRITICAL TO EFFECTIVE DISINFECTION Limited Detention Time (30 to 90 minute modal) = Ct approach Chlorine chemistry Free chlorine possible Multiple application locations Good Mixing Natural Energy Mechanical Energy Control Approach response time Control system need to respond to detention time 14 7

8 UV Design Dose For Reuse Reuse Media Filtration Membrane Filtration (MF and UF) Reverse Osmosis Minimum UV Design Dose (mj/cm 2 ) %T Turbidity Requirements Avg 2 NTU Peak 5 NTU Avg 2 NTU Peak 5 NTU Avg 2 NTU Peak 5 NTU 15 UV LIGHT Lamps wattage range from 250 to Low Pressure, Low Pressure high Output and medium pressure received conditional acceptance Validation and Performance testing (SCB) Mixing and flow distribution Cleaning critical Good distribution of UV Method of disposal/retreatment of off spec water Successfully used at numerous locations 16 8

9 How is Pasteurization Energy Efficient? Raw Water 70 F 73 F Pasteurized Water Preheater Module 220 F Exhaust 175 F 180 F Waste Heat Recovery Module Fuel (gas or liquid) 950 F Air Gas Turbine Generator Power 17 Total Coliform Dose Response Determined 4 Log Reduction in Total Coliform Temperature (deg F) 18 9

10 Ozone Not typically used for WW disinfection. Past History in US with Pure Oxygen Activated Sludge plants. Receiving new interest to THM/EDC Ozone will oxidize remaining COD before bacteria Becoming cost competative Received conditional accceptance 19 WRF and Other Studies Prove that Ozone Simultaneously Disinfects and Destroys EDCs Log Reduction of Seeded MS Ozone Only, Sand 0.6 Molar Ratio, Sand 2.3 Molar Ratio, Sand Ozone Only, MF Molar Ratio, MF 2.6 Molar Ratio, MF Applied Ozone Dose, mg/l Coliform Concentration, pfu/100 ml Total Coliform, Ozone Only Total Coliform, 0.6 Peroxide to Ozone Molar Ratio Fecal Coliform, Ozone Only Fecal Coliform, 0.6 Peroxide to Ozone Molar Ratio Applied Ozone Dose, mg/l 20 10

11 NON CONDITIONALLY APPROVED TECHNOLOGIES 21 Offers power efficiency of LPHI with lower number of lamps 800 W LPHO lamp Others such as WEDECO introducing new lamp technologies New Validation studies for Conditional Acceptance New LPHO Lamp 22 11

12 Chlorine Dioxide Must be generated on-site Requires Chlorine gas as feed (does not eliminate RMP) Research indicates less THM formation Variety of methods for generation Will need bench study to establish demand Limited success with application - City of San Luis Obispo 2 to 4 mg/l could achieve ND - Murray Peracetic Acid PAA appears to be effective disinfectant based on limit pilot data in US/Full scale in Europe. Decompose to Acetic Acid, Hydrogen Peroxide, Oxygen BOD and Side reactions. First Full scale facility WEFTEC 2008 NY State Recent application in St. Augustine, FL showed a dose of 1.5 mg/l of PAA yielded similar disinfection results to 7 mg/l chlorine 24 12

13 Ferrate Ferrate (Fe +6 ) is a strong oxidant, which can be utilized in reacting with refractory organics, inactivate pathogens and assist the coagulation process. By producing the ferrate in a liquid form the cost of the ferrate drops to around 2 to 4 dollars per pound or less. This liquid form can produced on site. On going testing Use with other Disinfectants UV/H 2 O 2 Ozone/H 2 O 2 Generally for Advanced Oxidation of Organic Compounds side reaction Disinfection Peroxide 26 13

14 BCDMH BCDMH 1-Bromo-3-chloro-5,5- dimethylhydantoin Effective Component 96% effective halogen decomposes into HOCl, HOBr, and Cl in water Full scale demonstration for CSO disinfection in Japan. 6 mg/l BCDMH 6 minutes contact time Initial testing showing less toxic and less generation of DBP s 27 FUTURE REUSE DISINFECTION CONCEPTS 28 14

20 APIs in the Environment Background Information Active Pharmaceutical Ingredients (APIs) are among the emerging contaminants of concern that can be classified into three potentially harmful categories: API s Endocrine Disrupting Compounds (EDCs) Toxic Compounds Antibiotic/Antimicrobial Agents Endocrine Effects Antibiotic Effects Toxic Effects 39 APIs in the Environment Background Information Endocrine Disrupting Compounds (EDCs) Manifest themselves as defects to reproduction, development and behavior of an organism Can affect the endocrine systems at parts per trillion levels Other Common Sources of EDCs Detergents, pesticides, plasticizers, flame retardants, agriculture products, natural hormones from plants, humans and animals Toxic Compounds (Acute & Chronic Effects) Adversely affect living species & ecosystems Effects are dose-dependent Antibiotic/Antimicrobial Agents May play a role in proliferation of resistant strains of bacteria 40 20

21 APIs in the Environment Background Information Pathways of APIs to the ecosystem*: Discharges from manufacturing facilities (<5%) Typically result in the highest localized concentrations found in the environment Disposal of unused dosages prescribed to patients (<10%) Excretion of un-metabolized API s by humans and livestock (<90%) * % contribution is based on average dispersion of API s in the environment, contributions local to major sources (manufacturing facilities, hospitals, CAFO etc.) could be very different. * EPA Active Pharmaceutical Ingredients (APIs) Regulatory & Treatment Challenges Lack of information on fate and long-term effects Ongoing challenge to identify the extent of the contamination in the water supply Due to varied physicochemical properties, there is no universal treatment technology Certain technologies appear to be effective for a broad range of compounds such as: Biological Treatment Activated Carbon Adsorption Ozone Oxidation 42 21
