Passive Irrigation Controller

The Food and Agriculture Organization of the United NationsĀ 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

Pico-Hydro Turbine Design for Powering Water Disinfection

Background This project has been outsourced to WERL by a Toronto-based company that is currently developing innovative inline systems for water disinfection. The company is focusing on two potential markets for their technology: swimming pool treatment (reducing the amount of harmful chemicals a user must manually put in their pool) and small scale drinking water … 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
