Effect of ambient temperatures on disinfection efficiency of various sludge treatment technologies
Sewage sludge produced during municipal wastewater treatment has to be treated efficiently in order to reduce impacts on the environment and on public health. In Germany and many countries, large quantities of sludge are reused in agriculture in order to recycle nutrients and organic material. In order to quantify the effect of different ambient temperatures on conventional and advanced sludge ...

Molecular Chemical Grinder Improves Digestion in Sludge
Municipal wastewater treatment plants (WWTPs) can reduce the costs and liabilities of sludge handling and disposal and increase their organic solids conversion rate with the Advanced Fluidized Composting (AFC) Process or the Advanced Fluidized Co-Digeson & Co-Generaon (AFC2) Process from BioConversion Soluons, LLC (BCS). The conventional sludge treatment techniques of aerobic and anaerobic ...

The use of constructed wetlands for the treatment and reuse of urban wastewater for the irrigation of two warm-season turfgrass species under Mediterranean climatic conditions
Constructed wetlands (CWs) represent low-cost technology for the treatment and reuse of wastewater in urban areas. This study aimed to evaluate the pollutant removal efficiency of a CW system and to assess the effects of irrigation using treated urban wastewater on soil and on two warm-season turf species. The research was carried out in Sicily (Italy) on a pilot-scale horizontal subsurface ...

Biodegradation of PPCPs in wastewater treatment plants - a Danish case study
The non-restricted production and use of pharmaceuticals and personal care products (PPCPs) has led to their presence in effluents from treatment plants, which can pose a threat to aquatic organisms downstream. This study analysed the breakdown of six common chemicals in four Danish treatment plants. The findings shed new light on the factors affecting removal of PPCPs from waste, showing that ...

Full scale municipal implementations of the Agar IFAS process for municipal wastewater treatment
Wastewater treatment plant retrofits worldwide are motivated by two main developments: a. Changes in effluent quality regulations, either to more stringent BOD/TSS requirements, or to include nutrient (N and P) removal b. Increase in flows to existing plants, due to either population growth or to expansion of sewerage systems One process capable of giving a cost-effective solution for these ...

What is Wastewater?
What is wastewater? Wastewater, the waste discharge that first comes to mind in any discussion of stream pollution, is the discharge of domestic wastewater, which contains a large amount of organic waste. Industry also contribute substantial amounts of organic waste, some of which comes from vegetable and fruit packing; dairy processing; meat packing; tanning; processing of poultry, oil, paper ...
