IWP&DC presents news from exhibitors who will be at Dam Safety 2021 being held from 12-15 September in Nashville, Tennessee
Aquablok
Sediment Solutions, LLC and AquaBlok, Ltd, manufacturers of SediMite™ and AquaGate+PAC™, are to move forward in a cooperative agreement to provide scientifically viable remedies using activated carbon (AC) to remediate sediments contaminated with PCBs, dioxins, pesticides, PAHs and other hydrophobic chemicals. The companies’ products can be used to form a reactive layer beneath a cap, as part of a reactive cap, or for in-situ treatment of the biologically active zone of surface sediments. The products can also be tailored to a broad range of environmental conditions and water depths. Because SediMite and AquaGate+PAC deliver smaller-sized AC, treatment effectiveness is substantially increased for equivalent amounts of AC compared to AC delivered in a granular AC (GAC) form. This enables cost-effective solutions and provides communities and responsible parties with increased confidence in treatment efficacy when using AC. Sediment Solutions LLC. manufactures
SediMite which is a low-impact system for delivering treatment materials to sediment for in-situ remediation. SediMite is an agglomerate comprised of a treatment agent (typically activated carbon), a weighting agent (to enable it to sink and resist resuspension), and an inert binder. Sediment Solutions has a long track record of providing in-situ treatment solutions for sediments and provides clients our extensive expertise in the use of activated carbon for in- situ sediment remediation. AquaBlok, Ltd. is a manufacturer of composite
materials utilizing its patented coating and amendment approach. The company has a long history in the environmental industry and provides a range of products utilized in groundwater treatment and sediment remediation applications. AquaBlok uses its low-permeability bentonite delivery system in a range of geotechnical applications including, industrial impoundment
sealing, anti-seep collars (trench dams) around piping, cut-off walls in porous soil conditions, and levee and dam repair or construction. ●
Barr
Barr has announced that Phases 2 & 3 of the Mouse River Enhanced Flood Protection project earned the American Public Works Association’s (APWA) 2021 Public Works Project of the Year Award in the Small Cities Rural Communities category, in the $25 million - $75 million division. The project was completed in 2020 and included more than 8900ft of earthen levee, interior drainage pump stations, river crossings of municipal utilities, and 1600ft of bioengineered streambank restoration. For nearly a decade, Barr and local partner Ackerman-Estvold have worked with the City of Minot, Souris River Joint Board, and North Dakota Water State Water Commission on the planning, design, permitting, and construction of the plan. “This project is a product of the commitment and dedication of our staff, our partners at Ackerman-Estvold, and our clients at the Souris River Joint Board and the City of Minot. We are honored to receive such prestigious recognition and thankful for the many people who came together to bring this project to fruition,” said Jason Westbrock, a senior civil engineer at Barr and project manager for this project. “APWA is honored to celebrate the 2021
Projects of the Year awards. The award recipients exemplify infrastructure projects that are planned, designed, constructed, and maintained to advance the quality of life for all in their communities. With the challenges of failing infrastructure across North America, public works projects are critical to rebuilding our resiliency and telling our story to support infrastructure funding. Even during the COVID-19 pandemic, our public works heroes continued to deliver on their projects,” said APWA President
Mary Joyce Ivers, CPFP, PWLF. “I am proud and inspired by all of our public works members who continue to deliver outstanding, selfless services to their communities, even in times of a pandemic and emergencies. I am so excited to celebrate these Project of the Year recipients and look forward to meeting you in St. Louis at PWX!” Awards are won in four divisions and five
categories. The divisions are (1) projects less than $5 million; (2) projects of $5 million, but less than $25 million; (3) projects of $25 million to $75 million; and (4) projects of more than $75 million. The categories are (1) structures; (2) transportation; (3) environment; (4) historical restoration/preservation; and (5) disaster or emergency construction repair. Projects of the Year for the Small Cities/Rural Communities are awarded to those cities or counties with a population of 75,000 or less and in the same categories of structures, transportation, environment, historical restoration/preservation, and disaster or emergency construction repair. ●
FlOW-3D
Flow Science, Inc. has launched FLOW-3D (x), an optimization and workflow automation software, the latest addition to the FLOW-3D product family. The FLOW-3D (x) interface allows customers to build automation and optimization workflows graphically and intuitively to dynamically connect parametric CAD features to the CFD solution and provides the framework for effective batch simulations, postprocessing and data extraction. From optimizing geometric parts for improved weight- to-strength ratios to evaluating sensitivities in the design parameter space, FLOW-3D (x) offers a powerful platform for users to arrive at the best design solution, achieving greater certainty while reducing modeling and analysis time. ●
