Red Deer’s nutrient management facility soon underway to reduce phosphorus

Preliminary demolition work will get underway in one month’s time for the construction of a new $19-million nutrient management facility (NMF) in Red Deer,...

Moncton council insists on stronger measures to limit odours from biosolids facility 

After years of odour complaints about a biosolids composting facility in Moncton, New Brunswick, the city council is requesting that the facility either enclose...
Excess Soil Regulation

Naturally-elevated metals concentrations are resulting in more landfilling and less beneficial reuse of soils

Under this regulation, excess soils containing specific metals within the range of natural background concentrations may be prevented from beneficial reuse.

Evaluating the results of 12 years of monitoring PFAS in municipal wastewater treatment systems

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.

Moncton air quality study finds no health hazard from sewage odours

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

Harnessing the power of wastewater treatment plant digesters with co‑digestion

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.

Overcoming anaerobic digester failures: Shared lessons from municipal and industrial facilities

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

Quebec’s new biochar plant set to be largest in North America

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...

Québec bans U.S. biosolids imports until it develops PFAS protections

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...

Ontario’s Whitesand First Nation secures long-sought funding for biomass plant

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

Can thermal hydrolysis of sludge solve problems caused by micro/nanoplastics?

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.

Decanters provide smooth operation for military base’s WWTP

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