  1. Wastewater Treatment Presenter: Marius CaprariuIntroducing IBI Group December 2012

  2. Traditional Wastewater Treatment The objective of conventional sewage treatment plant designs has historically been compliance with environmental regulations for the lowest capital cost Municipal WWTP Unit Operations • Primary treatment • Secondary treatment • Tertiary treatment • Nutrient removal • Disinfection High rate solids separation processes Efficient aeration, N & P removal Effluent quality and space (membranes) Biological removal of nitrogen & phosphorus UV, onsite NaOCl generation IBI Groupwww.ibigroup.com

  3. Traditional Wastewater Treatment IBI Groupwww.ibigroup.com All the municipalities have developed, operated and maintained their wastewater treatment plants through collection of taxes from its customers. As the costs for raw materials, labour, energy and chemicals have all increased dramatically, the wastewater utilities are faced with higher costs that can only translate in higher taxes for the people.

  4. Consumer prices increase IBI Groupwww.ibigroup.com

  5. Water rates increase 2001-2012 IBI Groupwww.ibigroup.com

  6. Future Wastewater Treatment IBI Groupwww.ibigroup.com The primary revenue source to offset treatment plant capital recovery and operating expenses will be to recover some or all resources from the wastewater treatment plant and sell them to interested entities.

  7. Future Wastewater Treatment Continuous improvements will enable new objectives in future treatment plants necessary to conform with societal megatrends Objectives From net energy userto net energy producer Industrial and potable reuse of effluent Small carbon footprint Recover inorganics New revenue streams Public perception of“sewage treatment” Megatrends Sustainability Energy Climate change Less tax revenue Resource scarcity DevelopmentAreas Micro fuel cells Nutrient recovery Greenhouse gas mitigation Energy management Treated water reuse experience IBI Groupwww.ibigroup.com

  33. Recovery systems at a treatment level Energy recovery • Advantages: • Maximum energy surplus, thanks to minimal oxygen consumption and maximized biogas production • The process generates electricity – wastewater treatment becomes a power generator • Pollutants in the wastewater will no longer be seen as a problem but as an energy source • Case studies – Montego Bay, Jamaica – can produce approximately 6 MW for approximately 200,000 people • Comparable costs with a traditional activated sludge plant • Instead of consuming more than 2 million in energy, the plant will produce more than $900,000 annually, which in 10 years means more than $30,000,000 form NWC Self Powered Sewage Treatment – i.e. ESSDE IBI Groupwww.ibigroup.com

  34. Recovery systems at a treatment level Energy recovery Energy Efficient Treatment – i.e. STM IBI Groupwww.ibigroup.com

  35. Recovery systems at a treatment level Energy recovery • Advantages: • No blowers, aeration piping, or diffusers means very little energy consumption • No odors, no noise, & small footprint are additional benefits • In terms of energy requirements & range of treatment capability, the STM ranks highly compared with all other secondary treatment technologies Energy Efficient Treatment – i.e. STM IBI Groupwww.ibigroup.com

  36. Recovery systems at a treatment level Energy recovery Energy Efficient Treatment – i.e. Diffusaire IBI Groupwww.ibigroup.com

  37. Recovery systems at a treatment level Energy recovery • Advantages: • Reduces traditional aeration costs by over 50% • Easy installation: There is no need to empty the reactor basin or stop the treatment process for both installation and ongoing maintenance • Modularity: Each unit can be serviced independently without affecting the operations of the rest of the system Energy Efficient Treatment – i.e. Diffusaire IBI Groupwww.ibigroup.com

  38. Recovery systems at a treatment level Energy recovery Energy Efficient Treatment – i.e. SABRE IBI Groupwww.ibigroup.com

  39. Recovery systems at a treatment level Energy recovery • Advantages: • 95% less aeration energy, 85% less total energy • 30%-50% reduction in the amount of excess sludge compared to conventional processes • Modular design, odorless with a reduced footprint • Case study, 580 units housing development, Pointe Hanover, Jamaica: conventional activated sludge plant consumes 8.5 kW/h for the aeration and SABRE consumes only 1 kW/h • Capital cost is marginally higher, however the life cycle cost is lower than a traditional activated sludge plant Energy Efficient Treatment – i.e. SABRE IBI Groupwww.ibigroup.com

  40. Lessons to take home • Embrace new technologies as they will add revenue streams to your utility. • Your operations and maintenance costs will be reduced • When you implement a new facility or upgrade an existing one, evaluate the technologies based on the life cycle costs and not capital costs • Start with a small plant and test the technology and train the operators • Always ask the consultants or contractors for reduced energy consumption technologies, otherwise you will be stuck with high energy bill every year • We are here to help, so just …..
