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.

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.
