Review of approaches to reducing adverse impacts of road deicing on groundwater in Finland

An increase in groundwater chloride concentrations was first reported 20 years ago in Finland. This discovery coincided with a sharp rise in the rate of road-salt application – the annual amount of NaCl consumed had increased from 50 t a−1 in the late 1970s to 140 t a−1 10 years later. To reverse these trends, research and development projects aimed at the reduced application of sodium chloride ...

Airport deicing effluent treatment and regulatory guidelines

Airport and airplane deicing is employed with the use of brines, salts, alcohols or glycols to remove and prevent or delay the formation of snow and ice. In the United States (US), the Federal Aviation Administration requires airlines that operate during icy conditions to perform deicing and anti-icing of aircraft and airfield pavement (USEPA 2011a). These deicing operations use large amounts ...

VSEP recycles airplane deicing fluid, protects the environment and provides eight month payback

New Logic has developed a unique membrane filtration system for treatment if all types of glycol based fluids. The objective is to recover as much glycol as possible and to remove contaminants and particulates added by usage. The process involves use of New Logic’s proprietary V✧SEP (Vibratory Shear Enhanced Process) vibrating membrane filtration system. Glycols have many uses including ...

Friction in Winter Maintenance: A new way to quantify Deicer performance and ensure highway safety

Ensuring the safety of motorists and passability of roadways in the winter months is critical in many regions of the country. Some of the most useful parts of the toolkit many municipalities use to ensure roadway safety are deicing chemicals such as granular rock salt, salt brine, magnesium chloride, or calcium chloride. These chemicals function by effectively lowering the freezing point of ...

Airport De-Icing Operations and Waste Water - Case Study

De-icing of aircrafts and airfield pavement is important to ensure the safety of passengers and cargo operators. These operations can have negative environmental impacts, due to the presence of ethylene glycol and propylene glycol, which contribute to high levels of BOD in surface water. Regulations are in place to ensure that waste from de-icing operations are properly collected and treated. ...

MCI®-2020 Gel: A Deep-Reaching Solution for Corroding Rebar

Mitigating corrosion of embedded rebar is a perennial problem for reinforced concrete structures, requiring preventative maintenance and repair. Topical corrosion inhibiting treatments require a clean, properly prepared surface area to work as intended. Cortec’s MCI®-2020 Gel is designed to work when proper surface preparation cannot be achieved or is economically undesirable, by ...

Is Green a Color or an Objective?

“Environmentally friendly” is a term that is applied with a spatula in today’s products’ labels in ever increasing numbers. What does it mean? Does it mean it’s better for nature, people, pets, or for the profit line of the company offering it? In the industry and elsewhere, we see a marked increase in “green-washing” of products and issues; ...

In situ Remediation of 1,4-Dioxane using Electrical Resistance Heating

An increasing number of states are establishing enforceable 1,4-dioxane cleanup goals due to recent improvements in analytical detection methods and existing carcinogenic risk information for 1,4-dioxane. Historically, 1,4-dioxane was used as a stabilizer for chlorinated solvents, primarily 1,1,1-trichloroethane. In addition, 1,4-dioxane has been used in a broad range of products including but ...

How to Pick the Right Ice Melter For Your Needs

We get a lot of calls asking about what deicer to use. What are the best products to melt the ice and snow on city streets, parking garages, hospital entry-ways, sidewalks, and driveways? What about the daycare center where children crawl and they pick up deicers on their hands and then potentially taste them? How about the canine kennel where pets are exposed? Frequently that ...

Project PEHKO - Improving Productivity of Paved Road Asset Management - Case Study

PEHKO 2015-2025-2028 project is a co-operation project between Finnish Transport Agency. The PEHKO project has now been underway since 2015 and preliminary results have exceeded expectations. Right from the start the weakest links reducing pavement life and increasing cycle costs were identified. These sections, spread all over the network, covered only 10-20% of the length, but incurred up to ...

General Industrial Case Study

A flour milling facility was looking for options to reduce their electrical expense. When evaluating their electrical load they found PD blowers were a significant percentage of the overall load. They opted to evaluate a flour load-out system with a 75hp PD blower for their initial project. The Inovair Drop in Replacement turbo blower provided a solution to their needs. This option also allowed ...

Reuse turns stormwater runoff from a problem to an asset

With so much concern about water scarcity around the world, it seems a no-brainer that rain is a good thing. But nothing’s perfect. Even something as beneficial as precipitation can have its downsides. One problem, of course, is flooding. Another problem you may not have thought of comes with stormwater runoff in urban settings. What’s the problem? In cities, buildings and pavement ...

Wastewater Mining and Reuse: Creating Benign Future Scenarios

Wastewater mining: In addition to being perhaps the most uninviting combination of words, it sounds like a most unlikely idea. But for almost 30 years, Aqueonics, now headquartered in Greenville, SC, has pioneered such systems, starting in the ’80s, with its first wastewater mining project. For that project, Aqueonics provided an onsite or decentralized treatment system for a developer in ...
