Together We Can: U.S. Water and Ethanol Industry Exports

Expansion of the volume of ethanol exported to the rest of the world is critical to profitability and expansion of the industry. Exports continue to set records (927 million gallons in the first seven months of 2018) but can be limited by challenges created by inconsistency in quality specifications and the methods used to guarantee them. U.S. Water has stepped forward in the last two years to help our [...]

U.S. Water's ProClean AB 1000 Optimizes Ethanol Producer's Fermentation Process and Reduces Treatment Costs

Even with quality cleaning practices in place, there is a risk of bacterial infection during the fermentation process of ethanol production. When bacteria are present, it can inhibit yeast productivity and loss of alcohol production can occur. Many ethanol producers utilize an antibiotic program to control bacteria growth and optimize product yields. A Midwest ethanol producer was utilizing a competitor’s [...]

U.S. Water Featured in March 2018 issue of Ethanol Producer Magazine

Just Published! U.S. Water’s Mitch Manstedt, Strategic Business Leader – Biofuels, and Jim Lukanich, Director of Applied Technology, were interviewed in the article Sticking to It, published in the March 2018 issue of Ethanol Producer Magazine.  In the article,  Mitch and Jim discuss the impact The Food and Safety Modernization Act has on biofilm control options in the biofuels [...]

U.S. Water’s Unique Sulfur Control Solutions

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 [...]

FSMA Regulations and Their Impact on Water Treatment Chemistry for the Ethanol Industry

In 2011, the FDA was given a new mandate to require comprehensive, science based preventive controls across the food supply. These regulations, collectively called the Food Safety Modernization Act (FSMA), apply to food for both human and animal consumption. While there have been rules governing food additives and safety for many years, these new rules further refine the requirements around control plans. The new [...]

U.S. Water Launches New Non-Sorbitol Corn Oil Recovery Product Line for Biofuels

U.S. Water, a leading provider of integrated water and process solutions for industry, launched the first in what will be a series of products developed for the biofuels industry specific to corn oil recovery. COR™ NS is a new, non-sorbitol based product line developed by U.S. Water's Ethanol Process Technologies team to aid in the extraction of corn oil as a co-product for biofuels plants. [...]

With New ZLD System, Bushmills Ethanol Expects to Shrink Water Usage

reposted from West Central Tribune ATWATER – Bushmills Ethanol is helping lower the bar, and in this case, that’s a very good thing. The Atwater plant has joined the growing number of ethanol producers in the country reducing the water they use, and shrinking their environmental footprint by doing so. Bushmills Ethanol on February 28th began operating a newly installed zero liquid discharge [...]

U.S. Water VOxOUT® Successful in Emission Control

U.S. Water’s Ethanol Process Technologies (EPT) team engaged in a CO2 Scrubber performance comparison evaluation in an Eastern United States dry grind fuel ethanol plant with a 100 MMgpy nameplate. Parameters compared were: Compliance Reliability Application Cost Residual Bisulfite – and its impact on both yeast vitality and final product sulfur content Accompanying Value The EPT [...]

U.S. Water Announces COR™, Corn Oil Extraction Product Line

Corn Oil Recovery (COR™) is an enhancement additive designed to increase the removal of corn oil from mechanical separation systems at dry-mill ethanol plants from U.S. Water’s Ethanol Process Technologies (EPT) team.  The product will benefit all ethanol facilities that have existing corn oil separation equipment, or are contemplating corn oil separation equipment in the near future.  We have [...]

ZLD, A Sustainable Water Treatment Solution

Introduction Water supply issues and sustainability are emerging as a national concern with the energy sector coming under increasing scrutiny. This is certainly the case with the ethanol industry. State discharge regulations have and are dictating that plant designs incorporate technological solutions to minimizing water use. These designs involve utilizing equipment that allows flexibility in reusing water [...]
