Municipalities Moving Toward Anaerobic Digestion

As organic materials make up a greater and greater proportion of municipal waste streams, creative alternatives such as anaerobic digestion are needed. Although local governments often hesitate to experiment with technologies on the taxpayers’ dime, several cities are venturing forward into using anaerobic digestion for diverting waste and producing energy. Many of these efforts are the ...

Stir it up: Five tips for more effective industrial aeration

We all know that aeration is a simple but versatile secondary treatment, with uses ranging from removing gases and dangerous compounds from wastewater, to encouraging the action of microbes as they break down solids. If you’re using aeration in an industrial setting, you may be producing streams with concentrations of biological oxygen demand (BOD), chemical oxygen demand (COD), and ...

Investigation of the household hazardous waste stream in a Hellenic municipality

Hazardous waste (HW) in small quantities generated by households is often dumped into the mixed household waste. A variety of chemicals was recorded during a field research presented in the present paper. Aspects analysed in this work contribute to the categorisation of household hazardous waste (HHW) and quantification of them since lack of generation and composition data was noted in Greece. ...

Zero waste cities - are they possible?

Twenty years ago Maurice Strong, the secretary-general of the United Nations' first Earth Summit in Rio de Janeiro, declared that if our planet was to remain a hospitable and sustainable home for humans, the battle would be won or lost in major urban areas. Strong's message is even more important today, with more people now living in cities than in rural areas for the first time in history. ...

What is energy recovery?

Processes like incineration and anaerobic digestion not only provide sources of energy, but they also reduce waste volume The term “energy recovery” often is applied only to a narrow number of methods for converting wastes into energy, when in fact it applies to a broad range of technologies used to create heat, electricity, or fuel. Energy recovery gives governments and businesses ...

Case study - Pure oxygen injection pilot test

Introduction: The Moccasin Bend WWTP uses pure oxygen produced by a cryogenic oxygen plant for activated sludge treatment of the influent waste stream, which consists of municipal and industrial wastes. The waste stream contains a high proportion of high strength industrial waste, which results in a typical COD loading of about 2000 mg/L, which is approximately four times the strength of normal ...

Decentralized wastewater treatment using a bioelectrochemical system to produce methane and electricity

Biological electrochemical systems (BESs) have the potential for decentralized treatment in developing countries. A 46 L, two-chamber, hydraulically partitioned microbial fuel cell (MFC) was designed to replicate low-flow scenarios leaving a composting toilet. The co-evolution of electricity and methane in this MFC was evaluated by testing two distinct waste streams: synthetic feces (Case F) ...
