The bioavailability of cadmium from sewage sludge-amended soils.
, 1999 PhDCadmium is a potentially toxic trace element present, at low concentrations, in a variety of environmental media. The processing of waste-waters produces sewage sludge, in which cadmium may be present at high concentrations.

Mechanical sludge disintegration for the production of carbon source for biological nutrient removal. [PDF]
, 2007 The primary driver for a successful biological nutrient removal is the availability of suitable carbon source, mainly in the form of volatile fatty acids (VFA). Several methods have been examined to increase the amount of VFAs in wastewater.

BY-PRODUCTS FROM SEWAGE SLUDGE
American Journal of Public Health, 1920 Economy and conservation have worked for years at the problem of profit from sewage. Mr. Weston notes that many American cities have potential by-products enough to make recovery worth trying. English cities have found the American Miles process profitable. It will at least lessen the cost of sewage disposal.

Fate of polycyclic aromatic hydrocarbons during composting of lagooning sewage sludge [PDF]
, 2005 The fate of 16 polycyclic aromatic hydrocarbons (PAHs), targeted by the USEPA agency, has been investigated during composting of lagooning sludge. Composting shows efficient decrease of the content and the bioavailability of each PAH.

Developing and Testing a Citywide Inclusive Sanitation Financial Tool
Sustainable Development, EarlyView.ABSTRACT Citywide Inclusive Sanitation (CWIS) represents a paradigm shift in the provision of safely managed sanitation services with a framework of three outcomes—equity, safety and sustainability. There are several sanitation financial tools, but none of these fully address all CWIS outcomes. Citywide Inclusive Sanitation Financial Tool (CWIS‐FiT) is
