Development of Smart and Sustainable Aeration Technology

During the past several decades, overfishing has made wild capture fisheries unsustainable. As an alternative, aquaculture has grown rapidly with an average annual rate of 8.7% since 1970 [1]. In the Asia-Pacific region, over 18 million people engage in fish and prawn farming [2]. Majority of which are individual entrepreneurs or families who manage small-scale … Read More

Passive Irrigation Controller

The Food and Agriculture Organization of the United Nations¬†calculates that agricultural irrigation consumes 70 percent of our global fresh water supply, they further express that 60 percent of that water is then wasted before it is used by crops. An important cause of water waste is the inappropriate scheduling of the irrigation periods leading to … Read More

Design and Optimization of Pico-scale Hydro Turbines

This project has been outsourced to WERL by a Toronto-based company that is currently developing innovative pico-scale hydro¬†turbine systems, used for energy harvesting in both water disinfection and pressure regulation applications.   In the disinfection system, a generator coupled to the pico turbine provides power to an electrochemical cell appropriate for drinking water disinfection. The … Read More

Oil Sands Tailing Water Treatment System

Dissolute and emulsified (PM 10) organic compounds are one of the hazardous contaminations and represent a significant removal challenge in oil sands tailings treatment. Even with widely adopted technologies such as biological and membrane treatment methods, the effective removal is lower due to their small size and lower concentration. It is hypothesized that oil droplets … Read More

Solar Aeration System for Aquaculture

Aquaculture is a major food source in many low and middle-income countries (LMICs). Improving water quality for aquaculture can increase yields, improve food security, and reduce antibiotic use. In the developed world, aeration is used to significantly improve water quality. However, aeration is the third largest cost in aquaculture, limiting its use in LMICs. In … Read More

Photovoltaic Reverse Osmosis Systems

For many remote off-grid communities, the lack of access to reliable electricity and clean water is a challenge for their economic development Designing and implementing community owned and operated power generation alternatives and water systems is a step towards autonomy Water purification systems powered by renewable energy need to be cost competitive in order to … Read More
