Pharmaceutical Plant’s Efficiency Improves After Correcting Boiler Issues

After working with their water treatment vendor for three years, a Southern United States pharmaceutical plant was unable to identify the source of boiler scale and low condensate return rate. The boiler scale and a low return rate were causing increased fuel and operational costs. U.S. Water conducted a plant survey to uncover the boiler system issue. Within a week of the initial plant survey, U.S. Water had [...]

Snack Producer Utilizes New Foam Control Options and Saves $30,000 in Chemical Annually

A major Midwestern snack producer had concerns about the high costs of the defoamer product that they were using and were interested in finding an alternative that would be more cost effective. U.S. Water was already a current vendor for the snack producer’s utility water products and services within the plant, and offered assistance in other areas, which included optimizing the foam control needs of the [...]

Biological Augmentation Minimizes Odor, Improves Environmental Safety and Optimizes Operation at Wastewater Treatment Facility

A protein further processing plant located in midwest United States was concerned with objectionable odors, hydrogen sulfide levels, and poor system efficiency in their wastewater treatment plant. The cause of these issues was found to be a sludge cap on their waste receiving pit and the associated growth of anaerobic bacteria beneath the cap. To remediate this problem, select strains of naturally occurring aerobic [...]

Power Plant Water Treatment System Restored After a Decade of Non-Use

After ten years of inactivity, a midwestern combined cycle power plant needed to bring its water treatment system back into operation. The previous equipment had been sitting idle after the previous owner went bankrupt, and required major cleanup and upgrades. While other water treatment companies were offering a chemical exclusive program, it was evident the plant would require a complete integrated solution to once [...]

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 [...]

TowerAssure Program Provides Cooling System Protection, Improves System Efficiency and Reduces Water Usage at a Southern U.S. Airport

U.S. Water’s successful program at a nearby facility resulted in an invitation from a Southern U.S. airport to propose an alternate treatment program for their existing cooling tower system.  The airport practiced sustainable water usage by utilizing softened graywater in its cooling tower system, but the responsible decision to move away from domestic city water to graywater quickly led to concerns [...]

Feed Mill Facility Increases Efficiency and Reduces Chemical Usage with EnergyOUT™

A Midwest Feed Mill was treating its incoming well water for high levels of alkalinity with amine chemical. Unfortunately, amine is one of the most expensive chemicals used in water treatment. If the facility chose not to treat the well water for alkalinity, it could result in failure of the condensate return lines, a costly plant shutdown and capital equipment replacement expenses. U.S. Water’s EnergyOUT system [...]

Integrated Offering Achieves High Recovery Rates and Low Discharge Rates at Food & Beverage Plant

As a Midwestern food and beverage plant expanded, they found themselves outgrowing their previous water treatment footprint. While their production had significantly increased, their discharge permits did not. The Reverse Osmosis (RO) and Clean-in-Place (CIP) systems were approximately ten years old and built for smaller demand and production output. The controls and analytics had become antiquated and required [...]

Minnesota Power, U.S. Water Team Up to Save $35,000 in Annual Maintenance Costs

Minnesota Power's Arrowhead High Voltage Direct Current Terminal was experiencing scale and white rust build-up inside their cooling tower condenser tubes, creating obstacles cooling the inverter. If left untreated, the built-up could result in a costly asset replacement and unscheduled down-time. At the same time, the Minnesota Pollution Control Agency (MPCA) was instituting new phosphate discharge limits and [...]

Automated Chemistry Program Saves Hospital Over 3 Million of Gallons of Water Per Year

California's PIH Health Hospital – Downey was considering a new solution for its cooling towers and chillers to improve current operations. U.S. Water was asked to review the system and provide suggestions. After meeting with the facility's team, U.S. Water representatives conducted a full audit of the facility, which included a complete water analysis. During the audit U.S. Water discovered water [...]

U.S. Water’s PhosZero™ Program Improves Corrosion Rates and Meets Discharge Limits at Power Plant

A Midwest power plant was experiencing scale and white rust build-up inside their cooling tower condenser tubes, creating obstacles cooling the inverter. If left untreated, the build-up could result in a costly asset replacement and unscheduled down-time. The Minnesota Pollution Control Agency (MPCA) was also in the process of instituting new phosphate discharge limits, which encouraged plant management to take [...]
