Complete Autotrophic Nitrogen Removal (CANR) is a novel process where ammonia is converted to nitrogen gas by different microbial groups. The performance of the process can be compromised by an unbalanced activity of the biomass caused by disturbances or non-optimal operational conditions. This contribution describes the development of a fuzzy-logic based system for both diagnosis and control o...

The ability to efficiently and comprehensively evaluate synthetic routes at their earliest stage of development is especially important in pharmaceutical process research and development and chemical engineering laboratories [1 and 2]. The evaluation and optimization of typically complex synthetic sequences (involving many reaction parameters) frequently entails bench-scale experimentation of a...

The homogeneous Fenton reaction is a complex chemical system that involves hydrogen peroxide and dissolved iron salts to generate highly reactive hydroxyl radicals in acidic solution. It is also known that the degradation rate of the Fenton system is significantly enhanced when the mixture is irradiated with UV or UV/Visible radiation. This photo-assisted Fenton process, or photo-Fenton process...

Nuclear reactors require periodic maintenance and inspection to ensure continued and safe operations, and automation of inspection tasks through robotics can minimize the duration of reactor inspection outages in a safe and costeffective manner. State-of-the-art reactor pressure vessel inspection leverages remotely operated vehicles (ROVs), which are teleoperated, submersible robots. In order t...

This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...

In a time of increasing concerns about the immense energy consumption and poor environmental performance of contemporary processes in the chemical industry, there is great need to develop novel sustainable technologies that enhance energy efficiency. There is abundant chemical literature on process innovations (laboratory-scale) around the plasma reactor itself, which, naturally, is the essenti...
