Heat and energy requirements in thermophilic anaerobic sludge digestion

G.D. Zupančič, +1 more
- 01 Nov 2003 - 
TL;DR: In this paper, the heating requirements of the thermophilic anaerobic digestion process were studied in laboratory experiments at retention times from 1 to 10 days and the data gathered in the experiments was then used to perform a heat and energy analysis.
Journal ArticleDOI

Microbial ecology of the closed artificial ecosystem MELiSSA (Micro-Ecological Life Support System Alternative): reinventing and compartmentalizing the Earth's food and oxygen regeneration system for long-haul space exploration missions.

Larissa Hendrickx, +7 more
- 01 Jan 2006 - 
TL;DR: In this minireview, the development of a short-cut ecological system for the biotransformation of organic waste is discussed from a microorganism's perspective.
Journal ArticleDOI

A mixing layer theory for flow resistance in shallow streams

Gabriel G. Katul, +4 more
- 01 Nov 2002 - 
TL;DR: In this paper, the authors provide a unifying framework between canopy atmospheric turbulence and shallow gravel stream roughness characterization by merging a wealth of surface roughness characterizations independently developed in nineteenth and twentieth century hydraulics and atmospheric sciences and establish a connection between roughness formulations across traditionally distinct boundary layer types.
Journal ArticleDOI

Biological nitrate removal processes from drinking water supply-a review

Anoushiravan Mohseni-Bandpi, +2 more
- 19 Dec 2013 - 
TL;DR: Heterotrophic nitrate removal has the advantages of not requiring an organic carbon source; however, the slow growth rate of autotrophic bacteria and low nitrates removal rate have contributed to the fact that relatively few full scale plants are in operation at the present time.
Journal ArticleDOI

Energy recovery from secondary pulp/paper-mill sludge and sewage sludge with supercritical water treatment

Linghong Zhang, +2 more
- 01 Apr 2010 - 
TL;DR: In comparison to sewage sludges, SPP exhibited a greater capability for the production of HO and gases owing to its higher contents of volatiles and alkali metals, indicating a prospective utilization potential for SPP as a source of bio-energy.
