Enhancing dewatering, drying, combustion and utilization of pulp and paper mill biosludge

2017/18-2019/20 • $564,600 • PI,CO
Canadian pulp and paper mills generate more than 20 million cubic metres of raw biosludge per year. Biosludge is generated during biological wastewater treatment and consists to >98% of water with the remainder being bacteria and tree residues. Energy intensive dewatering can decrease the water...

Photoheterotrophy for economical production of bioplastics from municipal organic waste: Integration of polyphosphate metabolism and P-recovery chemistry to maximize PHA yields

2018/19-2019/20 • $353,066 • PI,CO
The municipal wastewater and organic solids waste industries are undergoing a resource recovery revolution. Producing useful biomaterials from wastes promises great economic and environment benefits. Important biomaterials to produce include the bioplastic precursor polyhydroxyalkanoate (PHA),...

Anaerobic digestion of waste activated sludge at psychrophilic temperatures with ozonation to reduce biosolids production and enhance energy recovery

2017/18-2019/20 • $340,000 • PI
The wastewater treatment industry is undergoing a major transformation by increasingly focusing on wastewater resource recovery instead of simply wastewater treatment. Energy is an important resource that can be recovered from wastewater, and several facilities aim at operating energy neutral...

FECES-TO-FARM: technologies and molecular tools for controlling the dissemination of antimicrobial resistance from humans to animals while recovering fertilizing nutrients

2019/20 • $226,780 • PI,CO
As the number one global public health problem, the spread of antimicrobial resistance has profound impacts on human health, agriculture, the environment, and global trade. Animal production is a known amplification reservoir of mobile antimicrobial resistance genes (ARGs), with the food-supply...

An ultracentrifuge for advancing research on characterization and remediation of emerging environmental pollutants and on green chemistry

2019/20 • $144,831 • PI,CO
An ultracentrifuge (high speed centrifuge) to enable innovative characterization of nanoparticles and biomacromolecules relating to cutting-edge research in the field of environmental engineering, green chemistry and nanotechnology is requested. Nanoparticles and biomolecules such as nucleic...

New technologies for wastewater resource recovery by anoxigenic photoheterotrophic biological processes

2016/17-2019/20 • $132,000 • PI
Tightening regulations on biosolids disposal and growing energy utilization increase the operational costs of wastewater treatment plants, and reduce the sustainability of municipal infrastructures. In response, the wastewater industry is converting from only treating wastewater for...

FECES-TO-FARM: technologies and molecular tools for controlling the dissemination of antimicrobial resistance from humans to animals while recovering fertilizing nutrients******

2018/19 • $180,342 • PI,CO
As the number one global public health problem, the spread of antimicrobial resistance has profound impacts on human health, agriculture, the environment, and global trade. Animal production is a known amplification reservoir of mobile antimicrobial resistance genes (ARGs), with the food-supply...

Linking the population structures of phosphate-accumulating organisms in wastewaters and treatment plants to enhance predictive abilities of bio-P removal process models

2016/17 • $25,000 • PI
The discharge of phosphorus (P)-rich wastewater is an important treatment consideration because P favours thedevelopment of cyanobacterial (blue-green algae) blooms in lakes and of anoxic zones in estuaries. P can beremoved by enhanced biological phosphorus removal (EBPR), a process requiring...

Mixed-culture biotechnologies producing storage compounds as biofuels and biomaterials: engineering waste treatment communities

2011/12-2015/16 • $105,000 • PI
Improving the sustainability of wastewater treatment systems passes in part by the recovery of value added products and energy such as bioplastics (e.g., polyhydroxyalkanoates, PHA) and biodiesel (from lipids). Microbial communities in activated sludge treatment systems naturally produce storage...

Phylogenetic characterization of the nitrifying populations in municipal wastewaters and in biological treatment systems for modeling and bio-augmentation

2013/14-2014/15 • $76,640 • PI
New regulations tightening the discharge of ammonia from municipal wastewater treatment systems require a year-round good performance of the nitrification process (which removes ammonia by converting to nitrate). It is well know that this process has reduced efficiencies at lower temperatures...

Modeling the RAS-ozonation process to reduce excess activated sludge production and its effects on the ecophysiology of nitrifiers

2011/12-2013/14 • $218,029 • PI
The drastic increase in wastewater treatment sludge disposal costs in Quebec and Canada within the last few years drives municipal facilities to look for new technologies to reduce excess sludge production. The ozonation of the return activated sludge (RAS) to partially solubilize the suspended...

Pathogen inactivation mechanisms during electro-dewatering of biosolids from secondary wastewater treatment

2010/11-2011/12 • $195,521 • PI,CO
The cost increase for the disposal of biosolids produced during secondary wastewater treatment and the need to improve environmental sustainability require the implementation of more efficient biosolids dewatering technologies. In this context, the Canadian Company EIMCO Water Technologies (EWT;...

Determination of the impact of wastewater disinfection processes on the virulence risk of Eschericia coli.

2010/11 • $113,309 • PI,CO
The availability of safe, clean water is an essential security element for Canadians. Urban populations generally rely on surface waters (rivers and lakes) for their drinking water supplies, but these same waters often receive effluent discharges from municipal wastewater treatment plants....

Integrating phylogenetics genomics and ecophysiology guided

2010/11 • $24,000 • PI
Designers of activated sludge wastewater treatment systems increasingly use mathematical models describing the activity of microbial communities to predict the future performance of the systems. These models used to be only based on very simple biochemical reactions describing the overall...
