Custom Plant Controls Upgrade Optimizes Aging Ethanol Facility Performance

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 The outdated equipment caused plant shutdowns and a loss in production, which can cost up to $10,000 per hour.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 [...]

Kurita America’s Integrated Solution for the City of Wausau’s New Municipal Drinking Water Treatment Plant

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 [...]

Feed Mill Facility Increases Efficiency and Reduces Chemical Usage with EnergyOUT

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 [...]

Saint John’s University Operations Meets New Water Discharge Permit Limitations

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 [...]

Foresight Aids in a Successful Installation

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 [...]

PhosZero Technology Provides Advanced Corrosion Protection

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 [...]

Missouri City Ensures Compliance through HMO Technology

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 [...]

DReeM Polymer™ Technology Cleans Boilers & Reduces Customer Fuel Spend

Problem 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 [...]

System Refurbishment Provides Cost Savings and Improved Performance

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. [...]

Iowa City Treats Radium Through Hydrous Manganese Oxide

Farley, Iowa was in need of a new water plant for the treatment of multiple wells containing iron and radium. When considering technology options, the city chose a Hydrous Manganese Oxide (HMO) technology over other available treatment options due to a number of cost-saving opportunities. One of the key benefits included reduced operating expenses due to the elimination of brine waste. Due to their extensive HMO [...]

Tribal Community in New Mexico Treats Arsenic Through Pressure Filtration

Santa Ana Pueblo, NM required an additional water treatment system to meet the needs of their growing community. After previously working on a project with Tonka Water, a U.S. Water Brand, and being impressed with the high level of customer service they had experienced, the Pueblo once again sought out the company’s expertise. Santa Ana Pueblo opted to pre-purchase the new treatment system for construction, [...]

HMO Technology Used in Illinois to Reduce Waste

A new groundwater treatment system was needed in Chenoa, Illinois to replace an aging reverse osmosis system. A design build approach was used for this project, and Tonka Water, a U.S. Water Brand partnered with the engineer and local contractor to help design a high efficiency system that met the City’s needs. Hydrous Manganese Oxide (HMO) technology was ultimately selected due to reduced waste, cost savings, [...]
