A Midwestern Power Utility Controls Zebra Mussels in its Service Water System with Chlorine Dioxide

This facility located on the Mississippi River had a serious zebra mussel infestation in its service water system. Previous chemical treatments of the system were largely unsuccessful and had provided only marginal relief from the problem. Several valves in the system had become completely plugged and were non-functional. A new and effective approach was required to resolve this costly problem.

Boiler Feed Water “Polished” With Mobile Demineralizer Trailers

A refinery in Northern California was unable to meet its desired boiler feed water silica specifications on a consistent basis. The higher silica levels led to an excessive blow down requirement in the boiler system. The higher blow down rates were significantly affecting the refinery’s water, chemical, and natural gas costs.

Boiler Feed Water Treatment Facility Optimized For A Kentucky Refinery

A refinery in Kentucky was experiencing difficulties with the quality and quantity of water from their existing water treatment system.

BP Solar Meets Expansion Needs, Reduces Operating And Maintenance Costs With CDI-LX™ High-Purity Water System

High-purity water system at BP Solar is exceeding the plant’s specification for electronics-grade water by producing 18-megohm water with less than 10 ppb TOC.

Carbon Filters Remove Chlorine To Protect Downstream Reverse Osmosis – RO – Systems

The incoming water supply used by a New England company contained chlorine which adversely affected the plant’s two existing reverse osmosis (RO) systems.

Carbon Filters Remove Chlorine, Chloramines And Organic Matter To Protect Downstream Deionizers And Resins

Chlorine, chloramines and organic matter in the feed water to a Northeastern U.S. facility were adversely affecting the existing mixed bed deionization system. The facility had purchased the mixed bed deionizer for increased water purity, but plant personnel were not aware of the need to remove the chlorine, chloramines and organic matter in the incoming feed water.

Chemical Plant Approaches Zero Discharge

A Gulf Coast chemical plant was faced with an unreliable demineralizer system to meet a proposed expansion of boiler feedwater requirements. In addition, the plant had a wastewater goal of zero liquid discharge.

Chlorine Dioxide Cleans High Efficiency Cooling Tower Film Fill at Southwestern Gas Plant

Microbiologically fouled high-efficiency PVC honeycomb type film fill has severely limited the heat rejection capability of this 4 cell cooling tower. In fact, the plant needed to flare in order to keep the upstream plant from reducing production. The plant had plans to reduce production and shut down the tower cell-by-cell to physically clean and/or replace this fill.

Chlorine Dioxide Controls Zebra Mussels and Improves Heat Transfer

This Northern electrical utility operates a fossil fuel plant on the Mississippi River and uses 250-300 million gallons per day of water for once through cooling. Over time, this facility became progressively infested with zebra mussels. Although no restrictions in the water flow had been measured, plant personnel took a proactive approach to prevent further infestation.

Chlorine Dioxide Decreases Plant Operating Costs and Improves Heat Exchanger Efficiency

This Midwestern power utility produces 200 megawatts of electricity from one 2400 psig coal-fired boiler. The plant can sell all of the power it generates. It is critical that the heat exchangers are kept free of any heat-transfer limiting biofilm. The process is cooled using a once-through system utilizing 170,000 gallons per minute. Microbiological control of this cooling system had historically been a problem due to wastewater discharges from a food processing plant upstream of the plant, discharging wastewater with a high microbiological nutrient loading. Chlorine gas fed continuously was required to maintain control of the system.
