Biosolids

Previous research has shown only partial removal and, in some cases, apparent formation of PFAS during some wastewater treatment processes, which was attributed to transformation of unmeasured PFAS precursors.

A new air quality study for the north end of Moncton, New Brunswick, says that while there are certainly unpleasant odours emanating from the...

Concerns can arise when implementing a co-digestion system that operates using both wastewater and municipal food waste. However, with the proper tools and the right collaborative partnership, WWTP operators can take the guesswork out of feeding and understanding the state of the biological system.

Municipal and industrial anaerobic digesters can be prone to process upsets and failures, which present significant issues for owners and operators.

Canada’s first and largest industrial-scale biochar plant — an $80-million project capable of eventually sequestering 75,000 tonnes of carbon per year — is set...

As a “sign of caution,” Québec has issued a temporary moratorium on biosolids imports from the U.S., as it works to establish control mechanisms...

After lobbying for the project since 1992, the Whitesand First Nation in northwestern Ontario has finally secured $35 million in federal funding for its...

A new study by researchers from the University of Alberta identified that thermal hydrolysis of sludge before anaerobic digestion could alleviate oxidative stress on the digester microbiome and maintain smooth operation under high levels of polystyrene nanoplastics in sludge. The study also found that thermal hydrolysis could also mitigate the spreading potential of antibiotic resistance genes in digested sludge, or biosolids, which can be encouraged by the high levels of polystyrene nanoplastics.

The wastewater treatment plant's most important goal in dewatering was to maximize the reduction of the volume of sewage sludge.

As Vancouver-based Axine Water Technologies reports some success in destroying per- and polyfluoroalkyl (PFAS) compounds in water and wastewater through electrochemical oxidation, the U.S.-based...

The Town of Bradford West Gwillimbury, Ontario’s second-fastest growing municipality, has hired infrastructure consulting firm AECOM as the design partner for a three-phase biosolids...

Ontario’s Centre Wellington Township has removed and replaced the 30-year-old roof of the Fergus Wastewater Treatment Plant’s secondary digester for biosolids, which had been...
