Assessment Of N2O Emissions In A Partial Denitrification Process Using Rope-Type Biofilm Media
As the wastewater industry intensifies its efforts to reduce greenhouse gas (GHG) emissions, understanding nitrous oxide (N₂O) generation in emerging treatment technologies is critical. This study investigates N₂O emissions in a partial denitrification (PDN) process using rope-type fixed-film biofilm media (BioCord™ Reactors) developed by Bishop Water.
Metal hydroxide intermediates: Why they matter for phosphorus removal
ClariPhos Rare Earth Coagulant outperforms traditional aluminum- and iron-based coagulants for phosphorus removal in wastewater treatment. Using cerium and lanthanum, ClariPhos forms stable, dense rhabdophane minerals, reducing sludge production, chemical costs, and achieving stringent phosphorus limits with greater efficiency.
BioCord® Reactors demonstrate partial denitrification process and mitigation of nitrous oxide emissions
New research presented at the 2025 WEAO Technical Symposium highlights BioCord® Reactors’ ability to optimize partial denitrification (PDN) for nitrite accumulation while significantly reducing nitrous oxide (N2O) emissions, a potent greenhouse gas. By fine-tuning factors like carbon source and COD:N ratios, this study advances sustainable nitrogen removal in wastewater treatment.

Dewatering and Containment of Heavy-Metal Contaminated Sediments with Geotextile Containers and Polymers. Developing and Validating System Performance and Design
A former mine site in Eastern Canada utilized a hydraulic process involving dredging, geotextile containment, and polymer conditioning to efficiently remove and dewater contaminated sediments, reducing environmental impact and enabling site reclamation.
Improving year-round nutrient removal to extend the life of a wastewater lagoon
A municipal wastewater lagoon faced ongoing challenges with nutrient removal, leading to potential regulatory risks and high maintenance demands. This case study details how BioCord’s fixed-film reactors were installed to improve nitrogen and phosphorus reduction, ultimately enhancing the lagoon’s operational efficiency and compliance.
Bishop Water completes water treatment project at industrial lagoon to remove metals, PCBs
The environmental remediation of a two-hectare industrial lagoon in Port Hope, Ontario, was an important project to restore the natural features of the property and enable safe use by the community.
Ontario WWTP eliminates pH adjustment after switch to ClariPhos® coagulant
How can a wastewater treatment plant eliminate the need for pH adjustment while also reducing coagulant consumption? The answer lies in switching to a coagulant that is less acidic and achieves removal targets at lower dose rates than alternatives: ClariPhos® Rare Earth Coagulant.
Less acidic ClariPhos coagulant improves operator safety and phosphorus removal
Discover how switching to ClariPhos™ Rare Earth Coagulant enhances phosphorus removal efficiency, reduces pH swings, minimizes hazardous chemical use, and improves operator safety in wastewater treatment.
