MIOX Primary Disinfection Solution Eliminates Facility Safety Concerns While Optimizing Cooling Tower Performance

Fouling associated with the excessive growth of microorganisms including bacteria, algae, and fungi is a natural, but preventable, issue in most cooling tower systems. As a common problem, facilities have a variety of chemical and mechanical disinfection solutions available when developing a treatment program. A South Dakota industrial manufacturer was combining ozone and a non-oxidizing microbiocide to manage [...]

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 [...]

City Takes Advantage of Innovative Pre-Treatment Process to Rejuvenate Aging Plant

The utilities superintendent for the City of Savage, MN reports that an innovative, custom pre-treatment system in a well water treatment plant, for the removal of iron, manganese and radium, has keyed the rejuvenation of an aging plant back to reliable full service capability, all within the same footprint. He also notes new savings on both pre-treatment and polishing chemicals. The new pre-treatment system [...]

U.S. Water Establishes Treatment Program for the University of Texas at Austin’s Reclaimed Water Cooling System

The University of Texas at Austin power plants provide heating and air conditioning for two hundred buildings totaling over one-hundred million cubic feet of air space in offices, lecture halls, classrooms, laboratories, kitchens, cafeterias, and dormitories. The air conditioning is derived from six miles of underground chilled water loops. Texas has been under moderate to severe drought conditions. The [...]

Automation in Cooling Towers Reduces Water & Saves Hospital Thousands

With the State of California initiative to reduce water usage by 20% by the year 2020, many plants are focusing their responsibility to become a more environmentally friendly facility. One such facility included a large California hospital seeking to reduce the water treatment costs for their HVAC system. The hospital has three (3) individual cooling tower systems that service three (3) centrifugal chillers which [...]

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 [...]

Reducing Water Use in Ethanol Plants

republished with permission from Ethanol Today , December 2010 In the agribusiness sector where acronyms abound, some corn producers and ethanol plant investors are learning yet another one: ZLD It stands for “zero liquid discharge,” and it could be an important future trend for the ethanol industry as plants weigh the possible benefits of treating and re-using water that has already been [...]
