For those entrusted with the care and maintenance of stormwater management ponds, removing accumulated sediments is no small matter.
Removing accumulated sludge from a lagoon system is a fast, cost-effective way to restore treatment capacity and performance. But, a successful lagoon desludging project requires thoughtful planning and careful execution to sidestep potential pitfalls that could escalate costs and slow down production.
Gravity or pressure—which is more efficient when dewatering wastewater sludge? Both are proven methods to remove water from slurry and produce a cake that can be handled for disposal or land application.
non-aerated lagoons, can experience benthal feedback—a process where the turbulence of the warming water stirs up the sludge blanket and releases hydrogen sulfide gas along with nutrients that have accumulated in the settled sludge.
ARTICLE What to do when your lagoon’s effluent TSS is higher than the influent TSS What’s happening in a wastewater lagoon when the TSS of the effluent is higher than the TSS of the influent? And more importantly, how does an operator fix it? Excess sludge accumulation is often the cause of high effluent TSS […]
TECHNICAL PAPER Sewer surcharges can significantly impact the bottom line for breweries and other food and beverage processors. Adding an onsite wastewater treatment plant is one way to reduce sewer surcharges, but many options are costly, complex, and require a significant amount of space, which can make it tough to decide whether to install a […]
Spinning, squeezing, solar drying, there are many ways to dewater sludge from treatment plants and produce stabilized biosolids that are ready for land application or disposal. Selecting the best approach often considers several factors, including the speed at which dewatering must be completed, the space that’s available at the treatment plant to accommodate the process, and capital and operating costs.
Operators traded wheelbarrows for Bishop Solids Management solution to reduce time and labour in sludge handling
It used to take almost a month to dewater the same volume of sludge that is now done in less than a day at the Meteghan Sewer Treatment Plant (STP) in the Municipality of Clare, Nova Scotia.
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.
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.
