Residuals and Biosolids 2011: Adapting Residuals Management to a Changing Climate


Around the world, industrial as well as agricultural communities are moving toward more stringent regulatory requirements because of new climate policies. This year’s conference will focus on local and national perspectives on sustainable biosolids management technologies and programs that instill these new policies. The conference will also be hosting the Wastewater Challenge on Sunday, May 22nd and the Friends of Biosolids Social Event at the California State Railroad Museum on Tuesday, May 24th.

Event Type:
May 22-25, 2011
Sacramento Convention Center
Sacramento , CA , USA

Conference Workshops
This year, we are pleased to annouce four pre-conference workshops and one conference tour

Final Workshop Agendas:

Workshop A Agenda
Workshop B Agenda
Workshop C Agenda
Workshop D Agenda

Workshop A: Codigestion of High Strength Organic Wastes at Municipal WWTPs
Sunday, May 22, 2011 | 8:30am - 5:00pm

The overarching objective of this workshop is to provide the audience the current state of knowledge on existing codigestion programs, and provide them with the tools to understand the applicability of codigestion to their facilities.

Workshop B: Managing Nutrients at Biosolids Land Application Sites
Sunday, May 22, 2011 | 9:00am - 12:00pm

We will address the needs of decision makers who deal with biosolids land application and provide a comprehensive understanding of the fundamentals of biosolids land application practices with a focus on nutrient management.

Workshop C: Biosolids Gasification and Energy Recovery Systems
Sunday, May 22, 2011 | 9:00am - 12:00pm

We will introduce the fundamentals of the gasification process and compares two stage gasification and close coupled gasification systems as methods of energy recovery and power generation from syngas.  

Workshop D: Applying Bioassays to Biosolids
Sunday, May 22, 2011 | 9:00am - 12:00pm

For the past ten years, hundreds of research studies have focused on specific contaminants or suites of contaminants in biosolids. That research has led to the understanding that there are many synthetic and natural chemicals present in biosolids in trace amounts (low mg/kg or less), including some of concern with regards to persistence in soils and possible acute toxicity or endocrine disruption potential. This workshop will focus on the most recent research by exploring the fate of some of these contaminants in the soil environment after biosolids are land applied via bioassays.

Tour: Sacramento Regional Wastewater Treatment Plant (SRWTP) and Synagro Biosolids Recycling Facility (BRF)Tour
Tuesday, May 24, 2011 | 1:00pm - 5:00pm

This tour will visit the DAF and GBT thickening of WAS and four generations of anaerobic digesters. This will be followed by a visit to the Solids Storage Basins (SSBs) which are sludge storage ponds that are an integral part of the treatment process with odor control measures and harvesting dredges that achieve up to 50% additional solids destruction.
