Biosolids, sometimes referred to as sewage sludge, are the solid or semi-solid organic materials resulting from the treatment of wastewater carried through sewer lines from homes and businesses. Following treatment, the liquid effluent is typically discharged to a nearby receiving water (e.g., a stream or river), while the biosolids are removed ...
There is no doubt that biosolids contain extremely high quantities of microplastics as this has been reported on multiple occasions. Reports of microplastic concentrations in biosolids vary between studies but have been reported in the millions (per kg D.W.) in several studies with a highest value of 10,380,000 MP/kg reported to …

Introduction. Biosolids (BS) are nutrient-rich organic dry matter produced from wastewater treatment plants (WWTPs). Apart from their nutrient content, BS are also rich in microbial sources, pathogens, organic and inorganic contaminants (Marguí et al., 2016; Fijalkowski et al., 2017).There are many published works that describe the …
Biosolids are recycled to agricultural land in various forms: Digested cake is around 23% dry solids and can be safely and securely stored in field heaps before application and soil incorporation. Lime treated cake is about 25% dry solids and contains quick lime or slaked lime and can also be stacked in field heaps before application.

In the United States alone, billions of gallons of water are treated each day at water resource recovery facilities. Once the water is clean, a different challenge remains: determining what to do with the solids that are removed during the treatment process. The resulting mixture is often a unique semi-solid blend of organic and inorganic materials, …

The land application of biosolids can be subject to questions and concerns, suggesting a gap exists with public perception of biosolids. There is opposition amongst a segment of the population regarding the land application of biosolids in the Southern Interior of British Columbia in Canada. Kamloops and Merritt communities were …
Not all biosolids can be used for all purposes. This depends on the properties of the biosolids themselves, and is governed by some of the strictest guidelines in the world. Classification and regulation. EPA Victoria regulates the production, quality and use of biosolids to maximise their reuse while protecting the environment and public health.
The terms "biosolids" and "sewage sludge" are often used interchangeably by the public; however, the EPA typically uses the term "biosolids" to mean sewage sludge that has been treated to meet the requirements in Part 503 and is intended to be applied to land as a soil amendment or fertilizer. Biosolids may contain PFAS and other ...
The quality of the biosolids greatly depends on the source of wastewater (i.e., industrial vs. domestic) and the treatment processes. We aimed to determine the …

A higher abundance of tetA(P) was observed in biosolids obtained from WWTPs with anaerobic sludge processing and hospitals in their catchment area (A L, B M, F M) than in other biosolids (Wilcoxon rank‐sum test, p = 4.6 × 10 −10) and this effect is still significant when tested only within liquid sludge samples (p = 2.4 × 10 −5).
Biosolids are a product of the wastewater treatment process. Yes, that means sewage. However, the sewage is treated carefully to ensure it has beneficial properties and is not harmful.

Biosolids-treated PFAS (sludge) can pollute a variety of crops, soil, and water [38].The release of toxic air pollutants and fluorinated greenhouse gases results as the by-product of incineration of the waste containing PFAS [39], [40], [41].The increased use of PFAS in customer products has also led to its detection in composts (29 to 76 …
In February 1993, federal standards for the use or disposal of biosolids (40 CFR Part 503) were enacted (Federal Register, 1993). The Part 503 rule addresses land application and beneficial use of biosolids. Included in the rule was a two-year time limit on storage of biosolids for beneficial use.
Summary Biosolids are the major by-product of the wastewater treatment process. When treated and managed appropriately, they can be beneficially used for a number of purposes. Biosolids are treated sewage sludges. The ANZBP is careful to distinguish between sewage sludge and biosolids. Biosolids can only be considered as such once they …
