The advisory board and council were so pleased with the outcome of the luncheon; acknowledgement was received as a letter of gratitude was sent to Contego this month. The council reflected their response to the company’s efforts to be that of a positive impact when writing: “We appreciate the time and resources that you made available to us for our event” and the board continues to display great pleasure by stating “Christ for the World Chapel, and our sister chapels within the Tri-Faith Ministries at JFK, could not long survive and minister to the members of our JFK community, without the support of people and organizations like yours”.

Contego Systems accepts this recognition with great pride, and will continue to provide assistance for the chapel’s community as well as others.

Sal Calvino, president of IDS,and principal of the new alliance said, “from the first discussions that I had with Ed Danberry, Contego’s chief executive officer, and partner, it was clear that while the companies do not compete head to head, we shared many common traits and goals. We have an energy that puts customers, employees and company as the driving forces of everything that we do. We share a passion for the safe, efficient, and timely delivery of technology-driven deicing of aircraft. We are equally focused on the environment surrounding our workplaces. Both of our firms devote a great deal of resources to the training of our employees and support the communities in which we work.”

Danberry agrees. “ I was impressed, and delighted, to learn that IDS and Contego have so much in common. This Alliance will fortify our new business efforts and accelerate our ability to open new markets. It is a very exciting opportunity for both companies to bring substantial added value to our current customer base and to our prospective customers,” Danberry said.

The new alliance will capitalize on numerous economies of scale in the selling process and as a joint force they will be able to service operators of any size.

Integrated Deicing Service’s headquarters is located in Manchester, New Hampshire. Contego Systems’ home office is in Newark, New Jersey. The new alliance will operate in 19 cities with a staff of 1800 employees in season.

Contego’s deicing process utilizes a spray solution of glycol, an organic compound that is used in a variety of applications such as antifreeze, moisturizers, or lubricants in common household and pharmaceutical applications. Once the deicing process is completed, Contego collects the excess deicing fluid from the surface of the ground using specialized vacuum equipment. Under the new alliance with ThermoEnergy, Contego will use ThermoEnergy’s CASTion® Aircraft Deicing Fluid Recovery System to recover and recycle 98-99% purity glycol from the collected fluid.

“We are extremely pleased with the opportunity to add value and sustainability to Contego’s state-of-the-art aircraft deicing services in this $1 billion new potential market,” said ThermoEnergy CEO, Cary Bullock. “We look forward to not only working with Contego in the aircraft deicing fluid recovery market, but also forming relationships with other top tier companies to provide our wastewater and power generation technologies to other markets. Our goal is to increase value for our shareholders and partnering with companies like Contego is a major part of our strategic plan.”

ThermoEnergy’s proprietary CAST (Flash Vacuum Distillation) technology is a physical-chemical process that uses temperature and reduced pressure to separate water from glycols and then separate the glycols from their additive packages. The system may be combined with other technologies, such as filters or softeners, depending on the characteristics of the waste-water.

“ThermoEnergy ‘s CASTion® Aircraft Deicing Fluid Recovery Systems will help Contego eliminate glycol disposal costs, recover and recycle the value of the glycol in the wastewater fluids we collect, lower the overall carbon footprint of our deicing operations, and help us continue to meet or exceed EPA regulations,” said Ronald DeLucia, Partner and COO at Contego systems.

CWA’s goals.  Airports and their deicing operations will now be required by the EPA to regulate their effluent into the environment. Climate change induced by Global Warming is expected to cause more extreme weather events, including more ice storms and cold weather, leading to a greater need for deicing, and a greater burden on airports from these new regulations.

Since August 2009, the EPA has proposed technology-based effluent guidelines (ELGs) and new source performance standards (SPSs) under the auspices of the Clean Water Act.  These standards were specific to the runoff resulting from airport deicing operations.  According to the EPA guidelines available on the website, “Deicing operations include removal of ice from aircraft, application of chemicals to prevent initial icing or further icing (anti-icing) and removal of (and preventing) ice from airfield pavement (runways, taxiways, aprons and ramps).”

Mandatory Deicing

The FAA requires airlines to deice aircraft and airfield pavement to protect the safety of passenger and cargo operations. Aircraft deicing involves the removal of frost, snow, or ice from an aircraft. The responsibility for performing deicing/anti-icing varies between airports, but it is usually performed by a combination of individual airlines and support contractors, commonly called fixed-base operators (FBOs) or ground service providers.  The EPA estimated that the 218 largest primary airports account for approximately 85 percent of the deicing fluid used nationally.  The typical deicing season runs from October through April for most airports.  In colder areas like Minneapolis and Chicago, the deicing season may extend over a longer period. In places like California and Florida,  the deicing season may be shorter or deicing may rarely occur.

Deicing Operations

Airlines typically select procedures for deicing/anti-icing their aircraft, which are then approved by the FAA.  Although the FAA does not require airlines to use a specific technology when deicing, many airlines use aircraft deicing fluid (ADF). These ADFs contain ethylene glycol, propylene glycol or urea compounds that contain ammonium. During typical wet-weather conditions, 150 to 1,000 gallons of ADF may be used on a single commercial jet, while as little as 10 gallons may be used on a small corporate jet. An estimated 1,000 to 4,000 gallons may be needed to deice a larger commercial jet during severe weather conditions.

Centralized deicing pads may be located near terminals and gates, along taxiways serving departure runways, or near the departure end of runways. Each airport may use only one or a combination of all of these locations for deicing/anti-icing. Road salt (i.e.,sodium chloride or potassium chloride) may be used to deice/anti-ice paved areas that are not used by aircraft (e.g.,automobile roadways and parking areas) but are not considered suitable for deicing/anti-icing taxiways, runways, aprons, and ramps because of their corrosive effects on aircraft.

Most ADF is applied to aircraft through pressurized spraying systems, mounted either on trucks that move around an aircraft, or on large fixed boom devices located at a pad dedicated to deicing. Airlines typically purchase ADF in concentrated form (normalized) and dilute it with water prior to spraying. Most of the aircraft deicing fluid is not designed to adhere to aircraft surfaces. Consequently the majority of ADF is available for discharge due to dripping, overspraying, tires rolling through or sprayed with fluid, and shearing during takeoff. Once the ADF has reached the ground, it will then mix with precipitation, as well as other chemicals found on airport pavements. These chemicals typically include aircraft fuel, lubricants and solvents, and metals from aircraft, ground support and utility vehicles.  Water containing these substances enters an airport’s storm drain system. At many airports, the storm drains discharge directly to waters of the United States with no treatment.

Pollution Challenge

Runoff from deicing activity at airports is usually composed of water containing 1-40% ADF, grit and sand.  This ADF runoff is not directly dangerous to human health, but when it enters the environment, it can pollute bodies of water with increased organic burden, reducing the oxygen levels in the water.  This kind of pollution is defined as COD or BOD (chemical or biological oxygen demand) and is closely regulated by the EPA.

Unfortunately, runoff from the deicing treatment process can have the following negative environmental impacts on water quality:

●       contamination of drinking water sources, both on the surface and in groundwater

●       creation of noxious odors and discolored water in residential areas and parkland

●       reductions in dissolved oxygen

●       fish kills

●       reduced organism abundance and species diversity

Pollution Solutions

In order to reduce discharges of untreated ADF wastewater for this industry, EPA concluded that the best available technology would need to include two basic components. The first

component is a requirement to capture and collect a specified proportion (either 20 or 60 percent)  of available ADF. The second component is a requirement to treat the collected ADF to meet specified end-of-pipe discharge limitations.

The EPA has recently developed regulations requiring large airports to collect and store spent ADF, treat it biologically or by distillation and either dispose of it properly to a sewer system or recover it for reuse.  The regulations include technology-based effluent standards for discharges from airport deicing operations. Primary airports with 1,000 or more annual jet departures, and 10,000 or more total annual departures, would be required to collect the deicing fluid and treat the wastewater. The responsibility for performing deicing/anti-icing varies between airports, but it is usually performed by a combination of individual airlines and support contractors, commonly called fixed-base operators (FBOs) or ground service providers. Airlines typically select procedures for deicing/anti-icing their aircraft, which are then approved by the FAA.

These new regulations would impose a regulatory and financial burden on the airports, requiring them to collect the runoff from the deicing procedures, store it and either treat it on site or send it to a waste treatment contractor.

Controlled Atmosphere Separation Technology

The regulations proposed by the EPA require the deicing fluids to be cleaned in order to meet water quality standards before they are discharged into a sewer, ending up at a municipal sewage treatment plant.  The two methods that have been approved for the ADF treatment are biological methods and distillation.  Biological systems use organisms, such as bacteria, which are selected to consume the pollutants and remove them from the effluent.  Distillation is based on the evaporation of water from the effluent, capturing the vapor and condensing it into a cleaner liquid. Controlled Atmosphere Separation Technology (CAST) is an advanced vacuum flash distillation system with significant advantages over other methods used, including the added financial benefit of recovering the ADF for reuse or resale.

One provider of the CAST system is CASTion.  CASTion’s treatment solution requires that the spent fluids are reclaimed after the deicing process is completed.  They have partnered with deicing and reclamation specialists Contego Systems, LLC.  Contego Systems provides an eco-friendly method of collecting spent deicing fluid, utilizing their self-contained vacuum collection units and proprietary drain blocking units.

The central component of the CAST systems is a distillation chamber (still), where heated effluent is sprayed through an atomizer into a low pressure atmosphere, causing the water to evaporate from the effluent.  The effluent becomes highly concentrated, and additional contaminants collect at the bottom of the still, and are removed from the concentrated effluent. The water vapor is collected at the top of the chamber and condensed into water of much higher purity.  After treatment in the CAST system, the effluent is separated into high purity water, a high quality concentrated solution of the process chemical, which can be reused or resold, and a slurry or solid waste product from the bottom of the still.  Pre-treatment components include conventional precipitation and flocculants to precipitate dissolved phosphates and nitrates as well as granular-activated carbon to remove dissolved organic acids.

In a vacuum, the boiling point of liquids is lowered, so the water evaporates at a much lower temperature, typically 100-140°F, and the heat required to generate the vapor is approximately 1040 Btu/LB of vapor.  These low temperatures allow CAST systems to be manufactured with engineering plastics and simple technologies, such as hot water heaters, cooling towers and pumps.  In contrast, high temperature distillation requires specialty materials and complicated components, such as Freon-based refrigeration systems, or high pressure steam boilers.  Additionally, CAST systems can operate on low temperature heat sources, such as hot water heaters, low pressure steam or waste heat supplies. Operating costs are thus lowered through savings on fuel, and maintenance is reduced through the use of simpler, more reliable technologies.

The CAST system for propylene glycol, a common ADF, recovers 95% of the propylene glycol meeting ASTM standards at a purity of 99.9%.  This material can be sold to recover some of the cost of the system.  The waste product, which contains 5-6% propylene glycol and dissolved salts, can be disposed of as non-hazardous waste or incinerated.

CAST systems have distinct advantages over alternative options, which include other distillation methods, biological treatment, or reverse osmosis.  The reverse osmosis systems are much more expensive to install and operate, and the propylene glycol recovered in this manner does not meet ASTM standards, and is not have a value for resale.

In comparison with other distillation techniques, CAST systems have a built-in advantage since they operate at lower pressures.  Because of this, the system can operate at 125°F instead of at 212°F, as required for other distillation systems.  As a result, CAST systems can be constructed from less expensive materials, and require less energy to operate.  Since there are no internal parts other than the atomizer and some mist eliminators, scaling is kept to a minimum and maintenance is reduced.  Finally, the processing time is better performance, with more gallons of effluent treated per minute.

The advantages of the flash distillation over biological treatment include greater reliability, less variability and sensitivity to operating conditions, and the ability to recover the deicing fluids for reuse or resale.  The biological treatment destroys the propylene glycol or ethylene glycol by using it as a carbon source (food) for the biomass.  CAST recovers the ADF for reuse or recycle, with an economic value (currently about $3.50 a gallon).  This revenue can reduce the cost of meeting the rule.  CAST systems have a smaller footprint than biological systems, have lower capital and operating costs, and produce less greenhouse gases.  The biological systems are sensitive to low temperatures and do not work well in the winter, and therefore incur higher storage costs so they can process the PG in the warmer temperatures.  CAST systems can operate effectively and reliably under a wide range of conditions, and are appropriate for cold weather operations.

Double-stage vacuum flash distillation in Controlled Atmosphere Separation Technology (CAST) achieves 95% recovery of 99.9% pure Propylene Glycol and provides effective treatment with high reliability, low maintenance and a high rate of return on investment.  The CAST solution operates at lower temperatures, uses less energy, has a smaller footprint and a quicker processing time than other distillation, and recovers for reuse valuable product that is destroyed in biological treatment.

The system include three major pieces, first of which is a real-time data collection system via a touch screen module installed in each deicing truck. The touch screen collects information such as: customer, aircraft and flight numbers; the start and stop time of each deicing step; and fluid quantities sprayed.  All this information is easily accessible during or after the deicing event by the customer(s) using the second item of the software, the IceGuard Web Interface.  The IceGuard Web Interface allows for various reports, controls and key-performance indicators to be viewed and tracked.

Thirdly, a key component to the entire system is the IceGuard Pad Control Module, a software application installed on a deicing pad controller’s computer which allows an operator to receive aircraft data as they depart the gate by automatically recognizing the airline, aircraft number and type. Once placed in a deicing queue, the operator can assign the aircraft to a specific deicing slot and automatically transmit the data to pre-assigned deicing trucks. The system will even assign a deicing slot time to an aircraft preparing to leave the gate, allowing the airline to make the decision to hold loading and thus reduce the time queued to deice and the high cost of engine idling.
