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.

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.
