This Month's Practice Area
Each month in 2022, WEF will focus on a particular topic within the water sector.
May's Focus: Biosolids Resource Recovery
Biosolids contain nutrients, energy, and carbon that can be recaptured and reused. Careful treatment of wastewater and management practices of the finished product reduce or eliminate pathogens and minimize odors to transform what used to be seen as a waste into a safe, beneficial, and resource-rich product. Join us May 24 through 27 for the Residuals and Biosolids Conference 2022 in Columbus, Ohio.
Janine Burke-Wells and Ryan Batjiaka survey the effects of PFAS on the future of biosolids management in the Water Environment & Technology feature.
The biosolids management community must remain updated and active on what is happening with PFAS regulations, research, and technologies related to the future of biosolids management.
This Water Environment & Technology feature article looks at new approaches for treatment of biosolids that can address beneficial use, energy, disposal, and regulatory compliance.
A new testing method and labeling guidelines have been approved to enable producers of biosolids-based products to measure and advertise the amount of phosphate in a carbon-based fertilizer that is readily water soluble (and slowly releasing). This measure is referred to as water extractable phosphorous (WEP).
At the July 2021 meeting of the American Association of Plant Food Control Officials (AAPFCO; Arlington, Virginia), the organization recognized a new method to measure water-extractable phosphorus (WEP) for fertilizer products. The results from this method highlight the slower release of phosphate-phosphorus from biosolids-based (and other carbon-based) products. AAPFCO also determined that making labeling claims of slowly available phosphate for carbon-based products was allowable.
This manual discusses principles and concepts of energy sources and uses in the transport, treatment, and recovery of water and water resources. It also covers utility billing procedures and incentives and energy considerations for electric motors and transformers, pumps, controls, aeration systems, and more.
This comprehensive toolkit provides an extensive framework for communicating about biosolids in ways that are factual, science-based, and easily understandable by those who might be hearing about biosolids for the first time.
Stabilization converts sludge into biosolids to protect public health and the environment while maximizing resource recovery. Sludge is made up of solids separated from wastewater during the treatment process.
