Alkylphenol ethoxylate degradation products in land-applied sewage sludge (biosolids).
Alkylphenol ethoxylates, widely used in commercial and household detergents in the United States, can degrade during the wastewater treatment process to more toxic, estrogenic, and lipophilic compounds. These include octylphenol (OP), nonylphenols (NPs), nonylphenol monoethoxylates (NP1EOs), and nonylphenol diethoxylates (NP2EOs). These compounds have received considerable attention due to thei...
متن کاملCharacteristics of four alkaline biosolids produced from sewage sludge
Four alkaline biosolids were produced from sewage sludge using lime, lime/sodium silicate, cement and cement/sodium silicate. X-ray diffractometry (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX), single chemical extraction and sequential extraction were used to determine the characteristics of alkaline biosolids and untreated sewage sludge. The results of extr...
متن کاملOrganic contaminants in sewage sludge (biosolids) and their significance for agricultural recycling.
Organic chemicals discharged in urban wastewater from industrial and domestic sources, or those entering through atmospheric deposition onto paved areas via surface run-off, are predominantly lipophilic in nature and therefore become concentrated in sewage sludge, with potential implications for the agricultural use of sludge as a soil improver. Biodegradation occurs to varying degrees during w...
متن کاملMeasurement of flame retardants and triclosan in municipal sewage sludge and biosolids.
As polybrominated diphenyl ethers (PBDEs) face increasing restrictions worldwide, several alternate flame retardants are expected to see increased use as replacement compounds in consumer products. Chemical analysis of biosolids collected from wastewater treatment plants (WWTPs) can help determine whether these flame retardants are migrating from the indoor environment to the outdoor environmen...
متن کاملBiological testing of a digested sewage sludge and derived composts.
Aiming to evaluate a possible loss of soil habitat function after amendment with organic wastes, a digested sewage sludge and derived composts produced with green residues, where biologically tested in the laboratory using soil animals (Eisenia andrei and Folsomia candida) and plants (Brassica rapa and Avena sativa). Each waste was tested mimicking a field application of 6ton/ha or 12ton/ha. Av...
