The effect of iron and aluminium for phosphorus removal on anaerobic digestion and organic sulfur generation
The addition of iron or aluminium into activated sludge basins for phosphorus removal is likely to impact both the efficiency of the anaerobic digestion process and the generation of odor-causing compounds following digestion and dewatering. In this study, the impact of iron and aluminium addition on digestion and odor-causing compounds was investigated by using batch digestion of combined ...

Wastewater Treatment Plant - Newport, New Hampshire - Case Study
THE CHALLENGE Newport, New Hampshire is a small New England community of 6000 residents. The treatment plant treats primarily residential sewerage, although Newport is home to an internationally known firearms company, which also sends its waste to the municipal plant for treatment. This 1.3 MGD plant which operates at an average of .75 MGD, was built in 1971 and upgraded in 1988 to secondary ...

Fate of phosphorus during anaerobic digestion of sludge from an EBPR plant
As part of their ongoing commitment to produce safe sewage sludge for recycling to agricultural land, Anglian Water are expanding their enhanced sludge treatment operations at four key sites across the Eastern region. The project at Whitlingham STW uses thermal hydrolysis as a pre-treatment to anaerobic digestion as the main sludge treatment process. As well as producing an enhanced treated ...

The impact of advanced digestion on incineration of sewage sludge
Abstract Traditionally, when incineratin sewage sludge, it was preferable to burn raw undlgested sludge, as digestion - by extracting some of the energy from sludge- subsequently reduce its calorific value. However, when considering incineration as part of a wider strategy, the desicion whether or not to include digestion becomes less clear. Since, virtually all of the requirements of ...

Thermal hydrolysis, anaerobic digestion and dewatering of sewage sludge as a best first step in sludge strategy: full scale examples in large projects in the UK and strategic study including cost and carbon footprint.
Abstract This paper shows that by using thermal hydrolysis process (THP) as a pre-treatment for anaerobic digestion (AD) it is possible to develop a step wise approach to sludge strategy that is cost effective and flexible. By generating a low volume of non odorous, well dewatered and safe digested cake it is possible to recycle sludge directly to agriculture or dry it for fuel use or ...

Wastewater treatment facility uses ‘monsters’ to better manage screening, odor and trash
As wastewater pours into the Cobourg Water Pollution Control Facility located on the outskirts of this Canadian town, it comes loaded with organics, trash, debris and chemicals. A large perforated plate screen system, called a Monster Separation SystemTM, is the plant’s first line of defense and removes all unwanted solids in order to protect downstream processes.Managers at the facility report ...
