International Case Study: Benchmarking Efficiency Improvements: Leading-Edge Integrated Wastewater Treatment and Re-Use Systems in Israel |
This session will describe the management of the largest and most efficient integrated waste water treatment and reuse system in Israel; and one of the largest of it's kind globally. It contains a modified efficient Activated Sludge modular plant, using the SAT-Soil Aquifer Treatment as a Tertiary phase -recharging and retention time of the effluents in a sand aquifer, pumping and re use by crops irrigation in the southern region of Israel. In the past 20 years extensive research and gradual efficiency improvements have been introduced.
- Developing more efficient ways of treating wastewater
- Optimising performance
- Environmental compliance
- Managing effluent treatment standards at a lower energy cost

International Case Study: Energy Optimization for Design of Wastewater Facilities in California |
This session will describe a DBO project in California using Membrane Bioreactors for a Water Reclamation Facility. This Facility does not have a discharge permit as all the treated wastewater will be used back within the community
- Application of a whole cost optimization of the membrane bioreactor for energy optimization of the MBR operation
- Optimization analysis for the aeration cycle of the MBR
- Optimization of the sludge management train with innovative, low-energy intensive dewatering equipment
- Analysis of the use of photovoltaic energy generation to offset costs during peak hour electrical demand
- Cost savings obtained during design by benchmarking against other conventional facilities

Contributing to the Implementation of WFD through Integrated Economic Optimisation of Urban Drainage Systems |
This session will describe the investigation of a whole catchment area of a particular wastewater treatment plant by comparing different approaches to optimize the overall performance of wastewater treatment in that area. In this optimising approach the research team investigated and assessed measures in the sewerage network (e.g. minimising infiltration water, expanding stormwater treatment) as well as measures on the wastewater treatment plant (e.g. increasing hydraulic capacity, optimising nutrient removal). The overall goal of the optimizing approach was to minimise the effects on the receiving waters by the effluents of the urban drainage system. The major outcome of this research project was that the combination of different measures (reducing infiltration water in the sewerage system, increasing the hydraulic capacity of the wastewater treatment plant, and optimising the throttle settings of the stormwater treatment facilities) proved to be the most cost-efficient approach to assure a good water quality in the receiving water.

Minimising the Risks of Pollution Events |
Pollution from sewers can have a major effect on the receiving waters, from aesthetic to major impact on water environs, at worst case leading to fish kill. Sewage pollution is by nature an unplanned event, and hence cannot be totally eliminated. Predicting when and how such events will occur requires a combination of techniques. Mitigating the impact of events that occur requires effective and rapid deployment of resource.
This paper looks at the various sources of pollution from sewers, such as blockage, collapse, equipment failure and uncontrolled discharges at a CSO. It will analyse the relative impact of different discharges, including the real effects on water quality, habitats and fauna. It will consider the various proactive techniques being employed to reduce occurrence and mitigation employed when these events occur. The paper will include a number of case studies to illustrate effect, events, tools and techniques.

Responding to the Impact of Rising Energy Costs and Pressure to Reduce Carbon Emissions in the Wastewater Sector: Asset Managers Point of View |
The regulatory requirements to meet new treatment standards has pushed up energy consumption in the wastewater sector whilst higher energy costs and the drive to reduce carbon footprint involves the need to develop more efficient ways of managing wastewater systems.
- Capital asset issues - striking the balance between investment and operating costs
- What methodologies have been employed to monitor energy use during processes
- Use of energy management plans on a wastewater treatment site: improving and controlling the management of treatment works to reduce energy consumption

Energy Reduction Through Design of Wastewater Treatment Plants |
Wide Bay Water are leading the way for the rest of Australia in respect of energy efficiency for wastewater treatment, having been commissioned by Queensland Government to look at the design and build implications of 84 wastewater treatment plants all over Queensland. The main drivers were to have the best environmental outcomes possible, whilst saving on cost efficiencies by giving one organisation the responsibility for outcomes. To make a big impact on environmental benefits, one of the major factors is energy reduction through design. Tim Waldron will describe the issues involved in creating an energy efficient process, as well as an innovative treatment process never been done in the world before and how the outcomes they set out to achieve will set international standards.

Technology/Vendor Panel: What New Systems and Innovations Do We Have in the Wastewater Supply Chain? |
Although there have been many recent steps forward in the field of energy use for process treatments, the industry still needs to see more suppliers coming up with better technologies, and to see more investment and more research activity in order to identify wastewater treatment technologies that are cheap, reliable to operate and that deliver environmental benefit at the least cost.
Panellists will include a selection of the vendors from the exhibition area.
