Though 70 percent of the world is covered in water, clean water still proves to be a scarcity. It has been predicted that water demand will exceed supply by 56 percent by the year 2025. Here are some water treatment solutions that help meet global demand for this imperative resource.
Parkson HiOx® Aeration Panels
Parkson, a leading supplier of advanced solutions in water treatment, has developed the most energy-efficient aeration device ever. The HiOx® Aeration System offers the highest dirty water oxygen-transfer efficiency, due to the fact that the panels span over more than 25 percent of the basin floor, whereas traditional panels only cover up to 15 percent of the floor. The system’s high density of aeration panels leads to an almost perfect oxygen distribution with the basin, generating significant energy recovery.
Aeration is considered to be the most energy-intensive process in an activated sludge treatment plant. Up to 75 percent of a plant’s total energy costs come from mixing and aerating within the secondary process. The HiOx® platform is a major breakthrough in aeration technology.
HiOx® systems installed at a wastewater treatment facility in Hidalgo, Mexico more than doubled the plant’s consistent delivery. The increased water production means the power generation end-user will be able to rely heavily on recycled wastewater, rather than the scarce freshwater.
“The Hidalgo installation has far exceeded the customer’s expectations. They have reduced the horsepower requirement from 900hp to 700hp and often run the plant with only a single 350hp centrifugal blower, while still meeting the required oxygen requirements. In addition to more than doubling the plant’s capacity, the HiOx® UltraFlex system has resulted in monthly savings between $15,000 and $40,000,” stated Vipin Lillaney, Parkson’s HiOx® Product Manager.
WaterPure International Inc™ Atmospheric Water Generator
WaterPure International has invented the highly-advanced Atmospheric Water Generator (AWG). The only one of its kind on the market, AWG utilizes a patented ozonation process, generating 100 percent carcinogen-free water straight from the atmosphere.
The AWGs extract moisture from the atmosphere from a condensation process that transforms that moisture into a pure drinking water. Various air and water filtration systems eliminate particle matter less than .01 microns in size. By using ozonation, micro-organisms are eliminated, such as bacteria and viruses. Upon testing of the WaterCycle system, water was determined to be 99.9-percent pure, which is higher than most tap water and bottled water, exceeding EPA requirements.
The company recently received its first order for commercial use. “With the first commercial units out the door, we are very proud of WaterPure’s engineering and production team. Readily shipping the initial lot of a large order, we are no longer just putting together samples and pre-production AWGs, we are now running a full commercial production facility. For less than 10 cents per gallon, our unique WaterCycle AWG can generate 7-12 gallons of water a day. We expect it to be used in schools, hospitals, homes, factories, RVs and on boats, yachts, and at sporting arenas, to ease the water crisis. Having replaced the standard UV-light purification process with the patented ozonation process, there is now absolutely no danger of contamination from a possible broken UV light, which is used in most other AWGs. We produce water that is 100 percent carcinogen free,” stated Paul Lipschutz, Chairman, WaterPure International, Inc.
GE GenGard 8000
GenGard 8000, the latest of GE’s GenGard product line, is an advanced cooling-water technology. The innovative system allows for lower-quality water to be used in the cooling process, while also preventing fouling problems or corrosion. Developed in response to rising energy costs, the GenGard 8000 minimizes operating costs and improves the efficiency of the cooling system. The result is greater production output, water conservation and ability to use alternative water sources.
The entire GenGard product line ensures reliable results, regardless of operating conditions. The next generation of GenGard will also decrease the need for sulfuric acid in cooling water systems, lowering environmental impacts.
Industrial facilities that use large amounts of water for cooling process equipment require cooling water systems that are capable of reusing water.
The new GenGard chemistry extends GE’s water treatment product line to the complete pH spectrum, from neutral to alkaline cooling-water applications. GenGard 8000 incorporates the most advanced deposit and corrosion additives available, eliminating the need for sulfuric acid for pH control. This reduction or elimination of acid usage at industrial facilities not only helps to reduce operational costs and increase environmental benefits, but allows customers to remain a step ahead of industry regulations that require acid reduction.
"With water consumption increasing on a global level, GE continues to invest in next generation technologies and innovative solutions to address global water challenges and help create a more sustainable environment," said Nancy White, product line general manager, chemical and monitoring solutions, water and process technologies for GE Power & Water. "This next generation of GenGard chemistry is a robust treatment program that helps customers meet their specific requirements and allows them to do more with existing resources."
Itronics successfully tests manganese recovery process
Itronics - a Nevada-based emerging cleantech materials growth company that manufacturers fertilisers and produces silver - has successfully tested two proprietary processes that recover manganese, with one process recovering manganese, potassium and zinc from paste produced by processing non-rechargeable alkaline batteries. The second recovers manganese via the company’s Rock Kleen Technology.
Manganese, one of the four most important industrial metals and widely used by the steel industry, has been designated by the US Federal Government as a "critical mineral." It is a major component of non-rechargeable alkaline batteries, one of the largest battery categories sold globally.
The use of manganese in EV batteries is increasing as EV battery technology is shifting to use of more nickel and manganese in battery formulations. But according to the US Department of Interior, there is no mine production of manganese in the United States. As such, Itronics is using its Rock Kleen Technology to test metal recoverability from mine tailings obtained from a former silver mine in western Nevada that has a high manganese content.
In a statement, Itronics says that its Rock Kleen process recovers silver, manganese, zinc, copper, lead and nickel. The company says that it has calculated – based on laboratory test results – that if a Rock Kleen tailings process is put into commercial production, the former mine site would become the only primary manganese producer in the United States.
Itronics adds that it has also tested non-rechargeable alkaline battery paste recovered by a large domestic battery recycling company to determine if it could use one of its hydrometallurgical processes to solubilize the manganese, potassium, and zinc contained in the paste. This testing was successful, and Itronics was able to produce material useable in two of its fertilisers, it says.
"We believe that the chemistry of the two recovery processes would lend itself to electrochemical recovery of the manganese, zinc, and other metals. At this time electrochemical recovery has been tested for zinc and copper,” says Dr John Whitney, Itronics president.
“Itronics has been reviewing procedures for electrochemical recovery of manganese and plans to move this technology forward when it is appropriate to do so and has acquired electro-winning equipment needed to do that.
"Because of the two described proprietary technologies, Itronics is positioned to become a domestic manganese producer on a large scale to satisfy domestic demand. The actual manganese products have not yet been defined, except for use in the Company's GOLD'n GRO Multi-Nutrient Fertilisers. However, the Company believes that it will be able to produce chemical manganese products as well as electrochemical products," he adds.
Itronics’ research and development plant is located in Reno, about 40 miles west of the Tesla giga-factory. Its planned cleantech materials campus, which will be located approximately 40 miles south of the Tesla factory, would be the location where the manganese products would be produced.
Panasonic is operating one of the world's largest EV battery factories at the Tesla location. However, Tesla and other companies have announced that EV battery technology is shifting to use of nickel-manganese batteries. Itronics is positioned and located to become a Nevada-0based supplier of manganese products for battery manufacturing as its manganese recovery technologies are advanced, the company states.
A long-term objective for Itronics is to become a leading producer of high purity metals, including the U.S. critical metals manganese and tin, using the Company's breakthrough hydrometallurgy, pyrometallurgy, and electrochemical technologies. ‘Additionally, Itronics is strategically positioned with its portfolio of "Zero Waste Energy Saving Technologies" to help solve the recently declared emergency need for domestic production of Critical Minerals from materials located at mine sites,’ the statement continues.
The Company's growth forecast centers upon its 10-year business plan designed to integrate its Zero Waste Energy Saving Technologies and to grow annual sales from $2 million in 2019, to $113 million in 2025.
