Rare earth coagulant helps Hartford, WI achieve stringent phosphorus limit of 0.075mg/L
When the state of Wisconsin created stringent new water quality standards in 2013 to protect surface waters from eutrophication, about 400 treatment plants received tough new discharge limits for total phosphorus, ranging between 0.5 and 0.04 mg/L.
BioCord vs MBBR for lagoon upgrades—improvements without expansion
R&D efforts for BioCord® Reactors focus significantly on optimizing its fine-bubble aeration system and low-energy compressors to provide the best possible oxygen transfer and ammonia removal rates, while using less energy than MBBR.
More than a sandbag: Geotube® containers protect shorelines, restore beaches, create wetlands and more.
Geotube® containers are a proven, cost-effective solution that not only protects shorelines from erosion, but rebuilds beaches and reclaims land from bodies of water for recreational, residential and industrial purposes.
Why does freezing improve Geotube® dewatering performance?
Geotube containers that are filled late in the year are often left onsite over the winter to experience the dewatering advantages that the freeze-thaw cycle brings. Once the thawing begins, those previously frozen Geotube® containers can give up a lot of water—in some cases up to 50% of their volume.
The impact of rare earth biosolids as a soil amendment
The precipitate from chemical phosphorus removal systems typically becomes a component of the total biosolids produced by a wastewater facility. Biosolids containing ferric and alum sludge are often used as a soil amendment to add phosphorus as well as other nutrients.
Bishop Water BioCord Reactors to be distributed in Chile by Novatech
Bishop Water BioCord® Reactors have made their way to South America as part of a new distribution agreement with Novatech, a rapidly growing Chilean company that specializes in solutions for aquaculture, slurry dewatering using Geotube® containers, and geotextiles for road construction.
PEI treatment plant simplifies batch sludge handling with VEPAS polymer system
A compact, non-mechanical polymer mixing system is making sludge dewatering easier and more efficient for the North Rustico Wastewater Treatment Facility (WWRF) in Prince Edward Island.
