Working for A Solution to Discharge Limits
The National Pollutant Discharge Elimination Systems (NPDES) permit program seeks to reduce the amount of water pollution to surface waters. This is accomplished by regulating point sources such as pipes or man-made ditches that discharge pollutants into public waters. In the summer of 2005, the Iowa Department of Natural Resources (IDNR) began to issue increasingly stringent discharge regulations to ethanol plants throughout the state in response to federal guidelines. These new regulations included reduced maximum concentrations for iron discharged in the receiving water stream.

Comprehensive Cooling System Protection
Shortly after the mechanical start-up at a large corporate data center, significant bacteria growth was discovered in the thermal storage tank. Some of the flow sensors were fouled, and biofilm had the potential of impeding heat transfer, which would raise energy costs. U.S. Water Services was asked to assess the problem and find a solution.

Low Phosphorous Cooling Chemistry Meets Environmental Restrictions
A customer in Michigan was faced with permit restrictions concerning phosphate in their cooling system discharge water. U.S. Water Services was asked to develop a low phosphorous treatment program, in order to allow the customer to meet these new tight discharge limits, while still providing excellent scale and corrosion control for their critical cooling system.

U.S. Water Boiler Lizard Prevents Corrosion During Off Season
In the past, corrosion of the boilers and deaerator was a severe problem during seasonal shutdown at a Midwestern college. A new boiler and deaerator were recently installed, and the chief engineer wanted to protect this new equipment from this type of corrosion. The chief engineer noted that almost all of the boiler corrosion occurred during the idle period when the equipment was drained for their annual inspections and maintenance.
