Chedoke Creek Sediment Dewatering Case Study
During the Chedoke Creek remediation project in Hamilton, Ontario, Bishop Water helped dewater nearly 140,000 m³ of dredged slurry. Using polymer conditioning and passive Geotube dewatering, the system reduced disposal volume and hauling requirements while supporting high-rate dredging operations.
Simplifying arsenic sludge management with passive Geotube® dewatering
Learn how passive Geotube® dewatering helps a Canadian gold mine contain arsenic sludge, reduce handling and achieve filtrate arsenic of 0.013 mg/L.
Rural wastewater plant overcomes operational challenges of harsh winters
A rural Ontario wastewater treatment plant struggling with winter phosphorus and TSS exceedances turned to Bishop Water’s ClariPhos® rare earth coagulant to improve settling, reduce sludge blanket issues, and achieve year-round compliance without costly infrastructure upgrades.
Holding the line: How Geotube® shoreline protection is standing strong in Little Shemogue
Facing severe coastal erosion and storm damage, homeowners in Little Shemogue, New Brunswick became the first in the province to install a Geotube® Shoreline Protection system. The solution provides long-term erosion control, withstands extreme weather, and supports a more natural, accessible shoreline compared to traditional riprap.
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.
