Sludge, biosolids, and the propaganda model of communication.
The Water Environment Federation's elaborate effort to rename sewage sludge as "biosolids" is an example in practice of the "propaganda model" of communications, which sees its task as indoctrinating target audiences with ideas favorable to the interests of the communicators. The propaganda model assumes that members of the public are irrational and focuses therefore on symbolic and emotional a...
متن کاملAlkylphenol 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 کاملCreating a Sustainable Biosolids Management Plan
A city with a population of approximately 12,500 operates two advanced wastewater treatment facilities (WWTF) with a combined treatment capacity permitted at 2.75 million gallons per day (mgd). Each facility discharges 100% of the effluent generated onsite to the reuse system for use throughout the city. Biosolids at each facility are aerobically digested and the city uses an independent contra...
متن کاملTrace organic contaminants in biosolids: Impact of conventional wastewater and sludge processing technologies and emerging alternatives.
This paper critically reviews the fate of trace organic contaminants (TrOCs) in biosolids, with emphasis on identifying operation conditions that impact the accumulation of TrOCs in sludge during conventional wastewater and sludge treatment and assessing the technologies available for TrOC removal from biosolids. The fate of TrOCs during sludge thickening, stabilisation (e.g. aerobic digestion,...
