“…The challenge lies in promoting the acceptance and implementation of UASB technology in South Africa, for example, by offering locally-designed plants for which initial investment cost is reasonably low. This type of approach has proven to be successful in Mexico, where 76% of the anaerobic market, including UASBs, is designed, constructed, and operated by national companies (Monroy et al, 2000).…”

“…This may partly account for countries like South Africa, Canada and USA having low penetration of the UASB technology in comparison to countries such as Mexico, Sweden, The Netherlands and India. For example, by 2000, Mexico had installed 3 times more digesters than Canada and over 90% of the number of digesters operating in the USA (Monroy et al, 2000). In the context of technology development, both political and market factors appear to have a critical role to play in the survival of a technology in the market, as demonstrated for the UASB.…”

Market dynamics offer positive (incentive) or negative (disincentive) feedback loops that shape the research needs for, or certain aspects of, a particular technology. Our case study results illustrate how market dynamics have influenced the evolution of research needs in the wastewater treatment sector, with specific emphasis on research on the seeding granules used to start up-flow anaerobic sludge blanket (UASB) reactors. Because of insufficient data on the actual market demand for seeding granules for UASB plants, surrogate data, on the number of UASB plants installed internationally from 1970 to 2007, were used to predict the potential future demand for seeding granules. Secondly, we also determined whether or not such a demand would provide sufficient economic justification for the installation of one or more plants for manufacturing seeding granules in South Africa. The direct relationship between the demand for seeding granules and increased numbers of UASB plants was based on the premise that the start-up of each plant required a seeding inoculum before effluent could be treated. Three methods were used to obtain the data used in this study, namely: a literature survey, a questionnaire survey, and interviews with people having expert knowledge of wastewater treatment technologies. Our findings suggest that the UASB technology has largely been marginalised in the wastewater treatment market because of the introduction of competing technologies, and due to high initial capital costs. As a result, South African market demand for the seeding granules is likely to be very small or non-existent, because the number of new UASB plants installed per year is likely to decrease in future. Secondly, our research suggests that market dynamics, political contexts and technologies will continue to change, exerting an increasing downward influence on the UASB technology over time.

“…Enrichments were performed from the sludge of two reactors. One reactor was an 80 m$ upflow anaerobic sludge blanket (UASB) reactor treating the wastewater of the cheese factory ' Caperucita ', located near the city of Queretaro in Mexico (Monroy et al, 2000). The mean temperature and pH of the reactor were 23 mC and 7n3.…”

“…The other one was a UASB reactor treating the wastewater of the ' Unipack ' factory, manufacturing cardboard from recycled paper and located in the city of Cuernavaca in Mexico. The reactor temperature was 35 mC and its pH was 6n9 (Monroy et al, 2000). The reactors were 300 km apart and were inoculated with sludge from different sources.…”

“…Anaerobic hybrid reactors have been applied for treatment of various kinds of industrial wastewaters and domestic wastewaters (e.g. Monroy et al 2000;Banu et al 2007). The first study on the performance of a hybrid reactor was reported by Guiot and van den Berg (1984) who obtained a high efficiency in retaining biomass by using packing material in a hybrid reactor (UASB ?…”

In the last 40 years, anaerobic sludge bed reactor technology evolved from localized lab-scale trials to worldwide successful implementations at a variety of industries. High-rate sludge bed reactors are characterized by a very small foot print and high applicable volumetric loading rates. Best performances are obtained when the sludge bed consists of highly active and well settleable granular sludge. Sludge granulation provides a rich microbial diversity, high biomass concentration, high solids retention time, good settling characteristics, reduction in both the operation costs and reactor volume, and high tolerance to inhibitors and temperature changes. However, sludge granulation cannot be guaranteed on every type of industrial wastewater. Especially in the last two decades, various types of high-rate anaerobic reactor configurations have been developed that are less dependent on the presence of granular sludge, and many of them are currently successfully applied for the treatment of various kinds of industrial wastewaters worldwide. This study discusses the evolution of anaerobic sludge bed technology for the treatment of industrial wastewaters in the last four decades, focusing on granular sludge bed systems.
