It produces high amounts of sewage sludge that can be managed and perceived in two main ways: as a waste it is discharged in landfill, as a fertilizer it is disposed in agriculture with direct application to soil or subjected to anaerobic digestion and comp...
متن کاملRelease and Recovery of Phosphates from Sewage Sludge
Some treatment plants in operation have not been designed to fulfill the required standards of phosphorus removal. A possibility to upgrade the efficiency of phosphorus removal could be elimination of the phosphorus returned with sludge processing liquors by releasing and recovering from sewage sludge. The phosphorus recovery can occur from sewage sludge by chemical methods or from supernatant ...
متن کاملThe Benthic Macrofauna of Sludge-affected Sediments in the Derwent Estuary, Southern Tasmania
The paper reports the findings ofan extensive survey of benthic invertebrates from the Derwent estuary in southern Tasmania, sampled during an investigation into the distribution and character of sludge emanating from a pulp and paper factory. In total, 45 invertebrate species were collected, but none was found in the sediment in the river channel berween the pulpmill (its effluent outfall) and...
متن کاملUsing Vitrification for Sewage Sludge Combustion Ash Disposal
The aim of this paper is to show possibilities for effective processing of hazardous waste using the vitrification method, which is recommended for disposing of ash from the combustion of sewage sludge and developing a process for the conversion of waste to a sustainable and environmentally safe product. The use of vitrification solves the problem of utilizing some hazardous waste by simultaneo...
