STARx: A smouldering solution to biosolids disposal
Around the world, wastewater treatment plant operators face the same conundrum: what to do with the biosolids that they spend so much effort removing from the wastewater. Some apply it to land. After all, this organic sludge is rich in nutrients. However, it can also contain a cocktail of different contaminants, from household cleaners, paint and solvents to industrial chemicals. Other treatment plants incinerate their biosolids. That’s a very expensive undertaking, since drying and burning such a wet material requires [...]
Biosolids modeling: helping engineers extract more value from sludge
Better, faster, cheaper. It’s the mantra of wastewater treatment plant engineers around the world. That’s why more of them are focusing attention on unlocking the full potential of anaerobic digestion: using the biogas produced to generate electricity and transforming sludge into valuable fertilizer. Now, an Ontario collaboration funded by SOWC is giving them the design tools they need to do exactly that. In a civil engineering lab in Hamilton’s McMaster University, Dr. Younggy Kim believes the key lies in high-temperature [...]
Hydromantis Boosts Capabilities of its Dynamic Simulator for Process and Energy Optimization in Wastewater Utilities
Hamilton-based Hydromantis Environmental Software Solutions Inc. specializes in engineering and consulting work for the wastewater industry, finding much of its success on account of its innovative GPS-X tool. Released more than 25 years ago, this powerful modeling and simulation software has become a leading option for the design, optimization, and general management of wastewater treatment plants. But as company President Rajeev Goel acknowledges, in its earliest of iterations the technology was a little ahead of its time. “When founded in [...]
