Simple residuals management system saves $6 million for water treatment plant

Perth WTP _ Bishop Solids Management Solution

A water treatment plant (WTP) can generate a significant amount of residuals from processes such as clarification, sedimentation, softening, iron and manganese removal, filter backwash and more. Conventional equipment to separate and dewater those residuals is often costly, but not for the Perth WTP.

The Perth WTP saved about $6 million in capital costs by implementing the Bishop Solids Management Solution to collect and dewater the sludge from its sedimentation tanks. This simple, low-eenrgy system uses only Geotube® containers, polymers and gravity to collect and dewater the residuals in a single step.

Read the case study to learn how the Bishop Solids Management Solution works and why it’s ideal for the Perth WTP. 

Simple, cost-effective sludge management in the far north

Municipal | DATE POSTED: October 6, 2021

The Pangnirtung WWTP, on Baffin Island, experiences below freezing temperatures for eight months of the year, which means every process must be indoors—even sludge management. A centrifuge or belt press was considered for sludge management, but the complexity, cost, high energy usage and limited access to parts made them impractical for the Arctic community.

Instead, the plant uses the Bishop Solids Management Solution, which relies on Geotube® containers, polymers and gravity for low-energy sludge collection and dewatering.

BioCord™ pilot system proves mettle for cold-weather ammonia removal

Pulp and Paper | DATE POSTED: September 13, 2021

Onsite wastewater lagoons at a petrochemical manufacturing plant in Western Canada were experiencing difficulty in meeting the ammonia discharge limit during cold-weather conditions. The three-cell lagoon system provides pretreatment of the facility’s sanitary and process wastewater before the effluent is released to the municipal sewer. But during the winter months, the system struggles to achieve the discharge limit set by the city.

Learn how our simple, low-energy BioCord pilot system demonstrated 97% ammonia removal under some tough conditions.

Coping with rising phosphorus loading at a municipal WWTP

Municipal | DATE POSTED: September 13, 2021

Greenhouses are growing rapidly in Kingsville, Ontario and along with them is the volume of nutrient-rich wastewater that is sent to the community’s Lakeshore West Water Pollution Control Plant (LWWPCP). The plant consistently meets regulatory limits for phosphorus removal; however, public works managers are taking steps to ensure it will continue to do so as nutrient loading increases. Maintaining tight control of phosphorus discharge is also critical to mitigate harmful blue-green algae blooms that are increasingly occurring in Lake Erie.

Learn how ClariPhos™ Rare Earth Coagulant could replace ferric chloride to improve phosphorus removal at the plant and avoid costly capital projects to expand clarifier capacity or add tertiary filtration systems.

Lagoon sludge removal provides affordable solution for algae and H2S issues

Municipal | DATE POSTED: September 13, 2021

Sludge accumulation was thought to be causing significant operational challenges for the O’Leary Wastewater Treatment Facility (WWTF). The lagoons were experiencing serious blooms of blue-green algae during the summer months and exceedances of TSS, BOD and coliform bacteria in treated effluent. Hydrogen sulfide (H₂S) gas, which was also attributed to the algae and sludge, was building up in a below-grade chamber that housed the plant’s UV disinfection system. Read the full case study to learn how our Bishop Solids Management Solution and Lagoon Cleanout Services helped solve the problem.

Geotube® Technology for Storm Pond Cleaning

Municipal | DATE POSTED: June 13, 2017

The City of Vaughan required sediment removal of three separate storm water management ponds. The city wanted to have a minimal impact on the surrounding community and environment. Bishop Water provided hydraulic dredging and Geotube® dewatering technology to contain the sediments.

Geo-Dredging and Dewatering has been involved with two separate contaminated site clean-ups involving train derailments, and the release of crude oil into the environment. Quebec River in 2014 and a river in Northern Ontario in 2015 were both cleaned using Geotube® technology.


Geotube® Sludge Management System in North Rustico

Municipal | DATE POSTED: March 9, 2017

A simple, effective dewatering technique has enabled North Rustico, PEI to take control of their sludge management while saving thousands of dollars in trucking costs. Their previous plant was undersized, located in the centre of town on the waterfront, and prone to flooding especially during large rainfall events.


Howard Campbell and Sons – Septage

Municipal | DATE POSTED: April 28, 2016

Howard Campbell and sons, located in Lyn, Ontario, operated 2 septage lagoons In October 2009,a full scale dewatering and containment facility was built and operates year round. Sampling of the captured sludge showed dewatered material be to within Ontario’s limits.
