The City of Savage, Minnesota had relied on legacy Tonka Water (now Kurita America) equipment at their No. 2 Water Treatment Plant since 1985. When it came time to replace the aging infrastructure, they wanted to keep aeration and gravity filtration, but also enhance the treatment process with detention. Kurita America’s Dualator ® III packaged treatment product was a good fit, which [...]
At ten cents for every 1000 gallons, the use of reclaim water provided significant water cost savings for a thriving and innovative 900+ bed hospital located in Western Florida. However, it also presented a host of challenges—one of which was microbiological growth. At the time, the hospital’s previous biocide solution consisted of a stabilized bromine program in conjunction with periodic chlorine [...]
A biofuels facility in the Midwest United States implemented an integrated Zero Liquid Discharge (iZLD) solution developed by Kurita America that significantly reduced water intake for ethanol production, enabling the facility to expand production while meeting plant integrity and environmental compliance needs. This holistic approach took into consideration all aspects of the facility – chemistry, engineering, [...]
Multiple Midwestern ethanol facilities within the same organization were experiencing controls failure due to aging PLC and HMI equipment. Current plant control equipment was more than ten years old and had reached end of life. The outdated equipment caused plant shutdowns and a loss in production, which can cost up to $10,000 per hour. Kurita America recommended an integrated controls upgrade solution to prevent [...]
The City of Wausau, Wisconsin was exploring options to address aging infrastructure concerns at their existing drinking water treatment plant. In 2017, they hired a consulting engineer who contacted Kurita America for input on available treatment process and equipment options. The pending capital improvement project was an opportunity to upgrade with new technology, improving water quality and overall efficiency. The [...]
A Midwest Feed Mill was treating its incoming boiler feed water with amine chemical to combat high levels of alkalinity. While amine can be effective at addressing alkalinity, unfortunately, it is one of the most expensive chemicals used in boiler water treatment. If the facility chose not to treat the well water for alkalinity, it could result in failure of the steam piping and condensate return lines, a costly plant [...]
In compliance with their existing water discharge permit, Saint John’s University’s central plant discharged their boiler streams to an on-campus wastewater treatment plant with the cooling tower blowdown discharged to a nearby lake. However, when the plant underwent the renewal of their water discharge permit, they faced new, tighter discharge limits. The new permit limitations required significant [...]
Tonka Water, a Kurita brand , (Kurita America) recently completed a municipal water treatment installation in Shannon, Illinois, with the engineering firm Fehr Graham , which has several locations in Iowa, Wisconsin and Illinois. Historically, the Village of Shannon had many challenges with its public water supply. A Kurita America filtration system with HMO technology was selected for radium removal, in [...]
Phosphorus has long been recognized as the controlling factor in plant and algae growth for many lakes and streams. A minor increase in phosphorous can fuel substantial increases in both aquatic plant and algae growth which can have severe impacts on a community. Phosphorous can originate from municipal and industrial facilities that discharge water as well as runoff from agricultural areas that makes its way into [...]
The city of Bonne Terre, Missouri, had plans to use groundwater from four different wells with varying levels of contaminants. A plan was needed to successfully treat the radium, iron and manganese detected in these sources at two separate sites. With an interest in pre-formed Hydrous Manganese Oxide (HMO) technology, the city made the decision to work with Tonka Water, a Kurita brand, to conduct a pilot study that [...]
A food ingredients production facility had a chronic issue with process leaks in their heat exchangers at their gelatin processing unit. This resulted in product being sent back to the boiler via the condensate. The gelatin is high viscosity which regularly wore out the seals of the heat exchangers. The gelatin, containing hard water, also caused foaming, and eventually significant scale was formed in the water tube [...]
It quickly became apparent to the new operator at the Goldfield, Iowa plant that their current water treatment system was not running efficiently. They decided to contact Tonka Water, a U.S. Water Brand, to request a service visit to troubleshoot some high service pumps. The service trip report recommended a refurbishment due to the age of the media and resin, as well as issues relating to vessel flow and performance. [...]
