  • FOREWORD

    This manual is intended for use by persons who areconcerned with the chemical testing, dosing, and controlof a shipboard water treatment program. Included areexplanations of why water treatment is required and adescription of the methods used in modern marine prac-tice. The purpose and application of each of the DrewMarine water treatment chemicals is explained. Thisedition has been updated to include the newest treat-ments and tests in our line.

    The power plants of modern steam and motor vessels aremore efficient today than at any other time in history.Boilers and diesel engines are designed to extract thegreatest possible amount of energy from the fuel and toturn that energy into work. Turbines, generators andauxiliary equipment are designed to make the most effec-tive use of the steam or mechanical energy that is supplied

    to them. Efficient operation of the marine power plantdepends significantly on the quality of the water that itreceives. Contaminants such as dissolved minerals, gases,oil, and even the water itself can cause serious damage topower plant equipment unless proper control steps aretaken.

    Testing is an important part of any water treatment pro-gram because the test results are the primary means ofcontrolling the program and of detecting problems. All testprocedures are described in this manual after discussionof the applicable treatment program. We refer the readerto the section entitled "General Information" which shouldbe read before conducting tests. Here, recommendationsare provided for proper sampling, general testing andrecording techniques.
