How a polymer dosing system can make or break your sludge dewatering process.
Polymer is the secret ingredient for maximizing dewatering and achieving high quality filtrate from the Geotube® containers in our Bishop Solids Management Solution. But selecting the right polymer is not enough to get the best results.
Simple residuals management system saves $6 million for water treatment plant
CASE STUDY The challenge: Avoiding the high cost of a complex, mechanical residuals management system 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. Dealing with these residuals often requires additional equipment and oversight to collect, thicken […]
Bishop Solids Management Solution for dewatering and reuse of excess soil
Eliminate the need to truck muddy construction slurry from hydrovac trucks to distant sites for dewatering or disposal. The Bishop Solids Management Solution provides an easy-to-use, affordable process for onsite collection and dewatering of excess soil excavated during urban construction activities.
Simple, cost-effective sludge management in the far north
Sludge management is challenging for the remote Hamlet of Pangnirtung, Nunavut on Baffin Island.
City of London relies on strength and durability of Geotube® containers for award-winning ash dewatering solution
After dewatering thousands of tonnes of ash, using dozens of Geotube® containers, the Greenway Wastewater Treatment Plant (WWTP) in London, Ontario reports that the five-year-old system continues to “exceed expectations” for reliability and performance.
Bishop Solids Management Solution — Dewatering for all occasions
We’ve dewatered a lot of stuff over the years.
Everything from ordinary wastewater sludge and excess soil from construction sites, to noxious slurries containing really smelly organics, industrial process wastewater, and even low-level radioactive materials.
How to eliminate sewer surcharges with a simple, low-energy system
Pre-treatment of high-strength wastewater before discharging it to a municipal sewer can be challenging, especially if high levels of BOD, TSS and ammonia are present.
Potato processor treats and reuses wash water with simple, affordable dewatering system
High-TSS wash water can cause storage ponds to fill quickly with sediment and increases the risk of overflow. Learn how an Ontario-based grower used the Bishop Solids Management Solution to create a simple system that collects and consolidates solids while producing low-TSS filtrate that can be reused in the washing process.
Simplifying Arsenic Sludge Management At A Gold Mine
Arsenic-laden groundwater continually infiltrates the shafts of a gold mine in Western Canada. As it’s pumped out, an onsite treatment system removes the arsenic to produce effluent that can be safely released. But the system also produces large volumes of sludge—about 1,900 litres every 45 minutes. The sludge was a challenge for the site’s existing media filtration system and a faster, more reliable and more cost-effective solution was needed. Learn how the Bishop Solids Management Solution provided a simple, low-energy solution that achieves dewatering, filtration and containment in a single step.
Lagoon sludge removal provides affordable solution for algae and H2S issues
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.
