During the anaerobic digestion of dewatered sludge, polyacrylamide (PAM), a chemical conditioner, can usually be consumed as a carbon and nitrogen source along with other organic matter (e.g., proteins and carbohydrates in the sludge). However, a significant accumulation of acrylamide monomers (AMs) was observed during the PAM biodegradation process. To improve the anaerobic hydrolysis of PAM, ...

The topical antiseptic agent triclocarban (TCC) is a common additive in many antimicrobial household consumables, including soaps and other personal care products. Long-term usage of the mass-produced compound and a lack of understanding of its fate during sewage treatment motivated the present mass balance analysis conducted at a typical U.S. activated sludge wastewater treatment plant featuri...

Pulp & Paper Canada T 93 107:4 (2006) ❘ ❘ ❘ 47 ISPOSAL OF SLUDGES produced from biological wastewater treatment facilities is costly for the pulp and paper industry. A novel biodrying process has been developed that raises the dryness of pulp and paper mill sludge to a solids level where it can be economically combusted in existing boilers [1]. The process involves an aerated biopile, in which ...

The goal of this study was to provide quantitative agronomic data and environmental performance through a life cycle assessment camelina in crop rotation. For purpose, [Camelina sativa (L.) Crantz] included rotation (camelina-barley [Hordeum vulgare (L.)]-camelina) fertilized with two organic fertilizers (dewatered sludge composted sludge) during three growing seasons (2015–2018). Three treatme...

The transformation of dewatered sewage sludge into vermicompost provides an advantageous solution in cases where the is not too contaminated with inorganic pollutants, especially heavy metals. In addition to conversion a product higher-added value, undesirable organic pollutants and micropollutants are partially eliminated. Anaerobically stabilized from medium-sized WWTP was subjected vermicomp...
