Water Quality and Waste-Solids Dewatering at a Zero-Exchange Recirculating Aquaculture System

To meet growing demand, the aquaculture industry is building increasingly larger land-based farms. There are few locations which can provide enough fresh water for their operation and the industry is forced to reduce its water requirements further by modifying recirculating aquaculture systems (RAS) to incorporate zero-exchange technology. Cooke Aquaculture Inc. is currently constructing a zero-exchange RAS at Johnson Lake, located in Pennfield, New Brunswick to produce salmon parrs. This facility will be the first of its kind in the Americas.

Advanced rechargeable zinc lithium-ion battery – Part 3

There is a growing demand for the electrochemical energy storage system (EES) to store the energy generated by renewable resources of energy such as wind and solar. However, renewables are intermittent in nature meaning that the energy can be produced only when the sun is shining, and the wind is blowing. Therefore, there is a high demand for an EES to store the energy during generation time and give it back to grid later.

Numerical modeling and optimization of the coagulation-flocculation process for seawater pre-treatment

The result of this project can be used by engineers to design a multivariable control system that will optimize the dosing of chemicals in seawater pretreatment. Besides, the plant operators and technicians will be able to perform 'what if' scenarios based on computer modeling results to ensure that the outlet water quality is not decreased. The model will also provide an understanding of the effective parameters that determine the optimum coagulant/ flocculant dosage required for an effective water treatment process.

Catalytic oxidative desulfurization of tire pyrolysis oil, fuel oils and their distillates

Thermochemical conversion of waste tires to useful energy resources is attractive to obtain pyrolysis oils with potential economic value. However, the high sulfur and nitrogen contents prevents its direct application as a drop-in fuel in refineries. Though, catalytic hydrotreatment can reduce these heteroatoms, the prohibitive costs of high pressure equipments and harsh reaction conditions necessitates other options including oxidative desulfurization to be explored.

Optimisation of multistage mixer-settler solvent extraction process for the recovery of value metals in leaching of low-grade ores and secondary materials

The demand for elements such as nickel, cobalt, zinc and silver in various applications has increased significantly. Innovation to recover these elements now plays a major role in metallurgical processes as established technologies have challenges in treating available ores while meeting the increasingly stricter environmental regulations. Additionally, secondary sources have become a valuable resource that requires further research.

Canadian Oil and Gas Production, Supply Costs, Economic Impacts and Emissions Outlook

In this study, an integrated model will be developed to forecast oil and gas productions in the next 20 years for Canadian basins. Using the output of the model, supply costs estimation, economic impact analysis and GHG emissions calculation will be conducted over the forecast period from 2020 to 2040. The developed integrated model will provide industrial partners and policymakers with a better strategy to make good investment decisions. This project is defined as part of CERI’s 2019-2020 research plan.

Comparison of biological effects of Ceylon cinnamon water Extract and metformin

The use of cinnamon as a flavoring agent and a remedy for metabolic, respiratory, and gynecological disorders is widespread throughout the world. Studies suggest that Ceylon cinnamon may be useful in the treatment of type 2 diabetes. This project will use a high-throughput method to analyze how a concentrated water extract of Ceylon cinnamon changes gene expression in human cells. The analyzed data will be compared to existing results from cells treated with the most common medication used for type 2 diabetes, metformin.

Development of Lignin-based Polymers and Nanomaterials for High Performance Engineering Applications

Lignin, a substance in the cell walls of plants, is produced as a waste when wood is processed into pulps, papers, and similar products. In addition, this organic polymer exists in massive waste wood chips generated by various forestry and wood processing industry sectors. To advance the circular economy and diversify forestry products, there has been a recent surge of interest to isolate and reuse lignin, especially in manufacturing of novel bioplastics and lignin-based nanomaterials.

Landfill Odour Management Strategies

Golder Associates Inc. is the Technical Lead Consultant on the Environmental Assessment for the expansion of the W12A landfill of the City of London. One key aspect of this project is landfill design alternatives and the impact on air quality and, specifically, odour issues. The proposed project aims at providing critically valuable information regarding local air and odour monitoring at the W12A landfill site, regional air and odour monitoring in the South London area, as well as an assessment of the industry best practices not currently employed that may be applicable.

Upgrading of heavy and high heteroatoms containing Hydrofaction™ Oil, to fuel blendstocks via Hydroprocessing and in-situ hydrogen production

The Project’s objective is to continue with development and optimization of the promising HTL biocrude upgrading approach that has been executed during the previous MITACS Converge/Accelerated project. The activities are going to be focus on in-situ hydrogen production to limit external cost of hydrogen and process optimization for the obtention of Jet and Marine fuel blend-stocks for transportation fuels.
