The water industry is facing unprecedented economic and environmental constraints because of not only increasingly stringent regulations [1] but large amounts of sewage sludge produced. The disposal of sewage sludge is one of the expensive items in a wastewater treatment plant (WWTP), usually ...
I went to the Back River Waste Water Treatment Plant the other day. I was looking for some surplus bricks and also to turn in a security gate swipe card that was given to me many years ago. Since I had not been there in a few years, I thought I would give myself a tour. It su...

although AD reduces the solids content of sewage sludge, the final residues still contain some solids that need to be treated. A common method is to conduct liquid-solid separation, returning the liquid to thewastewater treatment plantand managing the solids through landfilling, incineration, or com...
Sewage sludge becomes an asset - NOT a liability, after we install our biomass gasification and trigeneration plant at your city's landfill or wastewater treatment plant! We will then be able to reduce your city's sewage sludge expenses at least 50%. Additionally, when we generate green power...
The addition of telemetry alarm and rainfall data enables waste treatment plant operators and regulators to detect equipment malfunction and permit non-compliance, respectively. Professional and citizen scientists also benefit from improved identification of putative spills that might affect their study of ...
Fortin said city manager Jason Johnson will gather information and report back to council on the possibility of building one or more local treatment facilities. The regional project, which included a wastewater facility at McLoughlin Point in Esquimalt and biosolids plant at Hartland landfill in ...
Raw sewage sludgeis that which is simply obtained from awastewater treatment plant(WWTP). Raw primary sludge contains 4–5% solids (w/v) whereas secondary (activated) sludge contains 1–2% solids (w/v). Dufreche et al. (2007) [41] used the gravity settling process to treat the secondary...
The water industry is facing unprecedented economic and environmental constraints because of not only large amounts of sewage sludge produced but more stringent regulations. The processing of sewage sludge is one of the expensive items in a wastewater treatment plant, usually accounting for up to 50...
