The physico-chemical processes of coagulation, flocculation, clarification, and filtration, collectively referred to as “chemically-assisted filtration” (CAF), are integral to resilient drinking water treatment—their use to ensure the provision of safe drinking water is therefore a regulatory requirement across North America. Treatment credits are assigned based on achievement of filtered water turbidity targets.
Large amounts of sewage sludge (SS) have been generated yearly by municipal wastewater treatment plants (WWPs), which entail huge operational expenses and advanced treatments, and the final disposal of biosolids in agricultural applications is reduced because of the potential environmental risks (e.g., heavy metals and emerging contaminants) associated with biosolids applications.
This project will support a Master’s UNB student to investigate the impact of including pyrolysis products (bio-oil and biochar) in asphalt mixtures by designing asphalt mixes that meet the requirements set for pavement applications. The use of carbon-rich bio-oil and biochar; could positively impact the properties and rate of oxidation of asphalt materials. Also, the use of biomaterials contributes to the sequestration of carbon, preventing the creation and emission of carbon dioxide. Ensyn will provide the material (i.e.
The use of hand disinfectant appears to have become a common practice for infectious as well as non-infectious individuals across the world for years now. Recently, a strong push to enforce the usage of hand disinfectants after touching any surface in public places due to the pressure of the Covid-19 pandemic was seen worldwide. Many varieties of hand disinfectants for killing bacteria and viruses have been in use across the world. However, most of them use flammable solvents including alcohol as the main disinfectant.
Scaffolding, as a type of temporary structure on construction sites, provides access for trades to certain areas for performing construction activities. Depending on project sizes, the budget for scaffolding can account for a substantial amount of the total direct work budget. Failure to the management of scaffolding activities can result in cost overrun and schedule delays in the projects. Meanwhile, scaffolding management is challenging by its nature, e.g., ad-hoc trivial daily activities with various material components consumed at different locations.
A helical pile is a screw steel pile comprising a small diameter hollow shaft welded with one or multiple helices. It has been widely used to retrofit structures or provide foundation support for infrastructure. The current research and design practice of helical piles have heavily focused on the “capacity”. In contrast, little attention has been paid to the performance of these piles, i.e., the movement of piles. This research project aims to understand the load-movement response through static loading tests of helical piles with and without post-grouting in soft clays.
In this project different UHPC mixes will be proposed and tested for mechanical and physical material properties when subjected to extreme cold temperatures. The mixes which meet the required properties and are most economical will be used for further structural wall panel testing and will be proposed to the company. The proposed concrete mix will be used to build insulated sandwich wall panel specimens and structural strength test will be conducted on them.
In industrial areas like manufacturing units, logistics centers, and warehouses, floors are exposed to heavy traffic along with high mechanical loads and possible chemicals contact. This promotes the use of polymeric cementitious flooring compositions such as epoxy resin-based flooring compositions and polyurethane (PU) cementitious systems. The latter showed outstanding mechanical properties and do not suffer from the drawbacks associated with epoxy resin-based compositions. PU system is composed of two different binding systems: polyurethane (diisocyanate) binders and hydraulic binders.
The goal of the proposed research project is to improve the work productivity for the partner company (Ocean Steel) by identifying bottlenecks accurately in the steel fabrication workstations. This work included evaluating the current applied solutions in order to resolve the same problems encountered with Ocean Steel, which was done by conducting a literature review. However, many of the solutions that were found were not applicable to the Ocean Steel case, meaning that some improvement is required).
The outcome of the proposed research on heritage buildings could benefit the industry, including EVOQ Strategies’ work as they have been involved in a number of projects on heritage buildings. Keeping the above in mind, the following general objectives are identified for the current research: - Provide a detailed overview of existing technologies as well as the opinions of experts in the field of energy performance sustainability assessment for heritage buildings. Thus, in a sense, it serves as a benchmark for different researchers looking to design their own assessment tool.
