Every day in the U.S., more than 355 billion gallons of water are withdrawn from surface and ground water sources to serve industry and the public, according to a 2010 report from the U.S. Geological Survey. As the strain on water sources steadily increases, it is critical for all water users to work towards water conservation. The primary drivers towards water recycling and reuse practices are environmental [...]
Each year on March 22, the United Nations recognizes the importance of universal access to clean water and sustainable freshwater resource management through the celebration of World Water Day . This year’s theme is Nature for Water, and this year’s fact sheet discusses how nature based solutions are, “a sustainable and cost-effective way to help rebalance the water cycle, [...]
U.S. Water's Alexandra Causey participated on the Making Waves in Water Panel discussion during the Women in Cleantech & Sustainability Conference where she discussed water treatment for industry & processes, water conservation & sustainability efforts, along with health & safety
A water softener system is one of a facility’s the best methods of defense against scale formation due to hard water on heat transfer surfaces, such as heat exchangers and boilers. In addition to a savings in energy, water and chemical costs, a well maintained softener can extend piping and equipment life. Some of the most common issues an operator may experience when maintaining water softener equipment is [...]
Monitoring and controlling a boiler’s internal treatment program is one of the best ways to prevent system downtime and avoid major repair costs. Common equipment problems, such as corrosion, scale and deposition can result in over $60,000 in repair costs and 2-3 days of downtime. Implementing a boiler automation program offers facilities the system protection and reliability required to run efficiently and [...]
St. Michael, Minnesota – U.S. Water, an ALLETE Company (NYSE: ALE), announces the acquisition of Tonka Water. Tonka Water, a major supplier of municipal and industrial water treatment systems, has joined the U.S. Water family. The acquisition of Tonka Water will allow U.S. Water to expand its integrated water treatment equipment offerings and applications. Tonka Water’s engineers customize water [...]
Chemical feed skids offer reliable and consistent dosing of chemicals into process applications. When designed correctly, chemical feed skids have the ability to increase system productivity by maximizing operating costs and reducing chemical costs. Available in hundreds of configurations, U.S. Water's chemical feed skids are customized to meet each facility's unique application and specifications. There [...]
As water and energy costs increase, government regulations tighten and environmental stewardship initiatives progress, facilities must continue to enhance their system efficiencies. Reverse Osmosis (RO) equipment is becoming more common in water treatment systems. Unfortunately, even with high quality feed water, RO membrane scaling and fouling is inevitable. Regular cleaning and servicing of your RO system and its [...]
There is a lot of talk in the technology market about the Internet of Things (IoT). But, what does that mean and how does it affect water treatment technologies? As people living in a modern world, technology is the center of nearly everything we do. Human nature constantly drives us to improve our “things” through newly engineered technology. The Internet of Things (IoT) is about using technology to [...]
Let's start with the scrubber. Aldehydes, primarily acetaldehyde, in fermentation gas are considered to be “hazardous air pollutants (HAPs)” by EPA. Aldehyde control is often based on sulfites, which react with the aldehydes, making them “scrubbable”. If you use more than required sulfur dioxide (SO2) gas can freely pass through the final stages of distillation and dehydration and [...]
After commencing an enzyme trial, an upper Midwest ethanol plant discovered elevated sulfate levels as fermentors were cycled through the plant. Out of spec ethanol cannot be marketed, and plant operations needed to act quickly to fix the product to avoid costly product rejection fees or plant shutdown. The plant was familiar with 精东影业’s ethanol industry experience and the Ethanol Final Filter (EFF) [...]
After an ethanol plant initiated some significant process changes, they encountered a final product sulfate issue that they had not faced before. Although the process changes provided excellent yields and the related economics were sound – meeting the final product quality specifications for sulfate became a problem. Blending provided a degree of relief, but created logistical challenges. The customer looked to [...]
