International Workshop on Anaerobic Treatment Technology for Municipal and Industrial Wastewaters: Summary Paper

Abstract

This paper presents a summary of the ideas expounded in the presentations and the resulting discussions at the workshop held in Valladolid, Spain (24-26 September 1990). The formal presentations and discussions are included in the articles which comprise the rest of this issue. The main topics summarized are the characteristics of the anaerobic process, its technological implications relating to different reactor concepts and to different designs, the importance of correct waste characterization for appropriate treatment, the characterization of the biomass, and the influence of all these factors on the design and operation of anaerobic treatment systems. Sections outlining the research and development needs for the enhancement of this technology are also included.

Anaerobic Biogas Generation for Rural Area Energy Provision in Africa

“…Table 3. Some of the difficulties thwarting development of biogas technology in Africa (Mwakaje, 2007;Murphy, 2001, Lettinga, 2001Lettinga, 1995, Switzenbum, 1995Tafdrup, 1995;Iza et al, 1991) …”

Psychrophilic anaerobic treatment of low strength wastewaters

“…One of the major successes in the development of anaerobic wastewater technology was the introduction of high-rate reactors in which biomass retention and liquid retention are greatly uncoupled (McCarty, 1981;Iza et al, 1991;. This feature comprises a crucial issue for the treatment of low(er) strength wastewaters.…”

Upflow Anaerobic Filter with Dual Media – A Novel Concept

“…While UAF can handle high organic loadings (Weiland and Rozzi 1991;Young 1991), its main drawback is the presence of dead zones and channeling (Iza et al 1991;Weiland and Rozzi 1991 ). These problems are associated with the accumulation of solids within the reactor.…”
