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.

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.
ClariPhos® is now produced in Canada, giving wastewater operators a more reliable, cost-stable coagulant for phosphorus removal. With faster settling, reduced sludge, and improved performance over traditional iron and aluminum systems, ClariPhos delivers consistent results in a changing supply environment.
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.
Communities can significantly improve lagoon treatment capacity and cold-weather performance without expanding footprint or building complex mechanical plants. BioCord® Reactors provide a semi-passive, low-energy upgrade that enhances biological treatment, reduces capital costs, and allows existing staff to operate the lagoon with minimal change.
Cold weather can cause conventional phosphorus coagulants to freeze, gel, and disrupt treatment performance. ClariPhos® remains liquid to -40°C, allowing wastewater treatment plants to maintain reliable phosphorus removal through winter while reducing chemical usage, freeze protection requirements, and overall operating costs.
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.
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.
