The Environmental Biotechnology Industry
Dr Tony Brooke of CBIO gives an honest opinion of the current state of the Environmental Biotechnology industry and how it is perceived by potential customers What is the role targeted bioaugmentation has in optimising treatment plant operation? Risking an unfair generalisation the water industry could be labelled as broadly sceptical regarding the benefits of bioaugmentation. This scepticism ...

Mechanism and kinetics of Zn(II) removal from wastewater by immobilised beads of SRB sludge
The treatment of Zn(II)-bearing wastewater by immobilised Sulfate Reducing Bacteria (SRB) sludge beads of inner cohesive nutrient source was investigated, by which the traditional problems in SRB methods were resolved. The mechanism and kinetics model on Zn(II) removal were studied. The results showed that SO42− was reduced to S2− on the surface of SRB sludge beads, and Zn(II) precipitated ...

The effects of different aeration patterns on aerobic granulation
In this study, the effects of aeration patterns in terms of intra- (S1) and extra- (S2) aeration on aerobic granulation were investigated. Granules developed in S1 were retarded due to the high shear force of highly mixed air bubbles, and they were more solid while the S2 granules were porous with many distinct pores and channels. Mature granules in two series had comparable specific oxygen ...

Microscopic characteristic of biological iron sulfide composites during the generation process and the association with treatment effect on heavy metal wastewater
Heavy metal pollution is a serious environmental concern worldwide, resulting in both environmental and human harm. Recently, studies have shown that environmental biotechnologies based on sulfate reduction offer a potential for removal of toxic heavy metals. Biological iron sulfide composites are iron sulfide compounds generated in situ by sulfate-reducing bacteria. In this study, microscopic ...

Sono-biodegradation: a promising alternative to existing bioremediation methodologies
Pollution of fresh water has become a serious concern today for developing countries. There are umpteen treatment methodologies and protocols, but still there exists a demand for new technologies for wastewater treatment. Extensive research on pollutants and increased toxicological studies have paved the way for new technologies, such as ultrasound treatment of pollutants and wastewater ...

Use of various agricultural wastes for the removal of heavy metal ions
There is a need to develop innovative and alternative technologies that can remove toxic heavy metal pollutants from wastewater. In this study, two agricultural residues, cotton stalks and apricot seeds, were used to adsorb copper and lead in solutions. Sorption capacities of agricultural wastes were significantly affected by solution pH, adsorbent mass and adsorbent particle size. The adsorption ...

Enhancement of organic and nitrogen removal in up-flow floating filter media reactor for piggery wastewater treatment
Integrated up-flow floating media system utilised sponge cube floating bed for microbial attachment and suspended solid clarification. The first reactor was operated under anaerobic condition where high organic removal of more than 85% was reached. It was followed by anoxic/aerobic floating media reactors or chemical coagulation/air stripping units. When biological post treatment was employed, ...

The ORP and pH profiles during simultaneous nitrification and denitrification of low carbon municipal wastewater
The ORP and pH profiles and the stability of Simultaneous Nitrification and Denitrification (SND) for low carbon municipal wastewater treatment were investigated under the different aeration modes in Sequencing Batch Reactor (SBR). The results showed that the 92% removal efficiency for TN, the smallest average level of ORP and both of the variation of ORP and pH values are achieved in ...

Integrated environmental biotechnology-oriented framework for solid waste management and control in Nigeria
Several environmental problems arising from man's activity have to be solved in a cost-effective and an environmentally friendly approach. In this paper, a framework for an integrated management and control of solid waste in the south-east zone of Nigeria is presented. The major activities include collection and transportation of solid waste to designated areas, separation of reusable components ...

Biotechnology: The Ultimate Pollution Prevention Tool
Much has been written about biotechnology. Indeed, so much has been written that the word 'biotechnology' means many things to many people. To the medical/pharmaceutical community, biotechnology is big business, and one that has greatly advanced drug development. To others, crop biotechnology conjures up thoughts of 'franken-foods,' and similar provocative images. Biotechnology in environmental ...

Laboratory-scale investigation of integrated biological phosphorus removal and mainstream deammonification at the Terrence J. O`Brien Water Reclamation Plant. Proceedings WEFTEC.17
Abstract: In collaboration with the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC), the environmental biotechnology research group at Northwestern University (NU) is conducting a laboratory-scale investigation of enhanced biological phosphorus removal (EBPR) integrated with mainstream deammonification using primary effluent as feed. The research presented here includes (1) A ...

Mathematical modelling of biofilms and biofilm reactors for engineering design
Mathematical models are critical to modern environmental biotechnology—both in research and in the engineering practice. Wastewater treatment plant (WWTP) simulators are used by consulting engineers and WWTP operators when planning, designing, optimizing, and evaluating the unit processes that comprise municipal and industrial WWTPs. Many WWTP simulators have been expanded to include a submerged ...

Fouling with aerobic granule membrane bioreactor
Aerobic granulation (AG) and membrane bioreactor (MBR) are two promising, novel environmental biotechnological processes that draw interest of researchers working in the area of biological wastewater treatment. Membrane fouling in the combined aerobic granular membrane bioreactor (AGMBR) process and the conventional MBR process was investigated in this work. The irreversible fouling on ...

Biotechnology and biodiversity debates and policies in Africa
After a decade of global diffusion, and the realisation of some economic benefits, the environmental impact of Genetically Modified (GM) crop technologies remains inconclusive and a source of considerable threat to biodiversity-rich Africa. Drawing on evidence from Ethiopia and South Africa, this paper characterises debates, considers policy and discusses the rationale for proactive GM technology ...

Farmers' perceptions and risks of agro-biotechnological innovations in China: ecological change in Bt cotton?
This paper furnishes empirical evidence that Chinese farmers have perceived a strong increase in secondary pests (i.e. pests other than the cotton bollworm) after Bt cotton was introduced. The findings suggesting possible ecological change are based on a survey of 1000 farm households in five provinces in China. We also found that farmers continue to use higher levels of pesticide use than ...
