Research & Technology Development

Recreational and Potable Water Projects
Performance verification of a Low-Energy Disinfection Electrode: Hypochlorite Ions formed via the actions of this proprietary electrode facilitated water disinfection. This technology's application was in the recreational water industry.

Efficient Snow Melt Sediment Management
In collaboration with a private entity, EWMCE is working to provide the City of Edmonton with long-term technological and operations solutions to manage snow storage site sediment buildup and handling of the sludge in the City's snow collection pond system.

Performance Verification of a Physical/Chemical Wastewater Treatment System
The EWMCE provided a test protocol and subsequently acted as the verification entity for the ETV Canada verification of a novel wastewater treatment system slated to be a viable alternative to sewage lagoons. The EcoLibra Systems Inc. technology has been fully verified and a fact sheet is available on the ETV Canada website.

Freeze Separation for Salt Recycling
Improvements in the innovative sand recycling process were investigated to determine the best technologies for removing suspended solids from the water used to wash sand for recycling. In addition, a freeze separation technique was evaluated as a way to concentrate salt from snow pack melt so that it can be collected and reused for street sand application in winter.

Testing and Development of an Onsite Biological Aerated Filter Wastewater Treatment System
Optimization of a portable ozone enhanced biological aerated filter treatment system intended for construction camp and remote report applications. The BAF was improved to the extent that it would meet the APS SSP level 2 regulatory requirements even before ozonation.

Evaluation of Micro-Bubble Aeration/Diffusion Systems
The Technology Development program has evaluated various proprietary micro-bubble diffusion systems as applied to an activated sludge, as well as Biological Nutrient Removal (BNR) wastewater treatment process. One of the systems was also evaluated on its ability to dissolve ozone in wastewater.

Alum Sludge Evaluation
This investigation evaluated beneficial disposal options for alum sludge residuals from drinking water treatment plants, such as using a landfill cover material, or as a compost additive.

Improving Solids Removal at Wastewater Treatment Plants
Researchers use computational fluid dynamics and laser measurement techniques to improve the design and performance of aerated grit chambers and secondary clarifiers at EPCOR's Gold Bar Wastewater Treatment Plant.

Ceramic Membrane Pilot Plant
Development of methodologies and equipment in-house that incorporate ceramic membranes such as research tools in effluent treatment, general thickening applications, and MBR technologies.

Zeolite Media Technology Development
Development and optimization of a zeolite media treatment system for simultaneous removal of ammonia and phosphorous from wastewater effluent. Break-through curves and scale-up data were generated for client's future stages of development.

ETV Verification of a Super Controlled Flush
The EWMCE completed the testing of a super controlled flush which aims to reduce the amount of water used in flushing toilets. Retrofitting of this unit in large, older toilets will allow waste-use reduction without the necessity of replacing the toilets.

Grit Characterization for EPCOR Wastewater Treatment Plant
The EWMCE is working with EPCOR Gold Bar Wastewater Treatment Plant in characterizing the grit from various locations of the plant to enable a more efficient design of solids handling.

Enhanced Primary Treatment (EPT) Optimization
In collaboration with EPCOR Gold Bar Wastewater Treatment Plant, the EWMCE is participating in a project that will optimize the performance of the EPT in handling wet weather flows.

WERF Co-Digestion Study
In collaboration with the Water Environment Research Foundation (WERF) through CDM, the EWMCE has completed a study on the operation of a pilot project on co-digestion of municipal wastewater sludge with fats, oil and grease as well as biodiesel glycerin. In addition, research was performed to evaluate the use of biofilters for biogas oxidation.
