Wastewater Treatment Presenter: Marius Caprariu Introducing IBI Group December 2012

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

Wastewater Treatment Traditional Wastewater Treatment  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. 3 IBI Group

Wastewater Treatment Future Wastewater Treatment  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. 6 IBI Group

Wastewater Treatment Recovery systems at a treatment level 34 IBI Group Self Powered Sewage Treatment – i.e. ESSDE 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

Wastewater Treatment Recovery systems at a treatment level 35 IBI Group Energy Efficient Treatment – i.e. STM Energy recovery

Wastewater Treatment Recovery systems at a treatment level 36 IBI Group Energy Efficient Treatment – i.e. STM 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

Wastewater Treatment Recovery systems at a treatment level 37 IBI Group Energy Efficient Treatment – i.e. Diffusaire Energy recovery

Wastewater Treatment Recovery systems at a treatment level 38 IBI Group Energy Efficient Treatment – i.e. Diffusaire 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

Wastewater Treatment Recovery systems at a treatment level 39 IBI Group Energy Efficient Treatment – i.e. SABRE Energy recovery

Wastewater Treatment Recovery systems at a treatment level 40 IBI Group Energy Efficient Treatment – i.e. SABRE 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

Wastewater Treatment Lessons to take home 41 IBI Group 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 …..
