Conclusions
We underline the following advantages:
- Chlorine dioxide has allowed to minimize the growing of both micro and macro-fouling inside cooling systems of petrochemical plants at very low dosage rate,
- Monitoring system has demonstrated to be the “Brain” of the treatment programme. It has permitted to inject chlorine dioxide in a proper quantity and in the right moment, saving material and protecting the environment.

An Industrial Facility’s Guide To Cooling Tower Water Treatment
For an industrial company using a cooling tower for its facility, some type of cooling tower water treatment system is usually necessary to ensure an efficient process and lengthy equipment service life.If cooling tower water is left untreated, organic growth, fouling, scaling, and corrosion canreduce plant productivity, cause plant downtime, and require costly equipment replacements down the road.

Boiler Water Treatment: Lessons Learned
Background
Enormous amounts of water are used daily in boiler water operations. However, water normally contains various levels of contaminants, dissolved solids (minerals) and dissolved gases. These contaminants cause major operational problems and damage to boilers unless they are removed or controlled on a continuing basis. Correct application of chemical treatment programs can eliminate many problems associated with boiler operations. But other problems can and do impact operations.

Industrial Pretreatment Programs
Pretreatment is the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to, or in leu of, discharging or otherwise introducing such pollutants into a POTW. The reduction or alteration may be obtained by physical, chemical or biological processes, process changes or by other means, except as prohibited by 40 CFR 403.6(d)

Water Softening Treatment Plant Study City of Grand Ledge
Executive Summary
The City of Grand Ledge (City) retained Fishbeck to evaluate options for the replacement of the City’s existing iron removal treatment system. Fishbeck is evaluating three options as part of this process: the installation of a new iron removal system, the installation of a new softening system, and receiving water from the adjacent Lansing Board of Water & Light (LBWL) system. This report evaluates the second option, the installation of a new softening treatment system to replace the existing iron removal system. The City’s existing iron removal plant utilizes an AERALATER® Type II-Q Packaged Iron and Manganese Removal System by General Filter (Aeralater) for iron removal. The Aeralater is at the end of its useful life, and has significant signs of deterioration. The repair of the Aeralater system was investigated as part of a prior study completed by Fishbeck, which determined that repair of the Aeralater would be costly and would give a low return on investment. The City opted to move forward assuming that the Aeralater unit would need to be
replaced, rather than attempt to repair it.

An Introduction to Cooling Tower Water Treatment
TYPES OF OOLING WATER SYSTEMS. Cooling water systems remove heat generated from a variety of industrial processes. There are three basic types of cooling water systems: once-through, open recirculating, and closed recirculating cooling water systems. This publication describes once-through and open recirculating systems.

Best Management Practices for Industrial Water Users
Introduction:
The industrial water user should determine if implementation of each identified BMP measure to achieve water savings would be cost effective. The analysis should determine the cost effectiveness to the industrial water user of the lower direct costs of the saved water and other cost savings that may also accrue. Many operating procedures and controls that improve water use efficiency should be implemented simply as a matter of good practice. In other cases the industrial user may decide to implement BMPs based on non-cost factors such as public good will or political reasons. In evaluating equipment and process additions or changes, each industry should utilize its own criteria for making capital improvement decisions.
