FOREWORDThis manual is intended for use by persons who are concerned with the chemical testing, dosing, and control of a shipboard water treatment program. Included are explanations of why water treatment is required and a description of the methods used in modern marine practice. The purpose and application of each of the Drew Marine water treatment chemicals is explained. This edition has been updated to include the newest treatments and tests in our line. The power plants of modern steam and motor vessels are more efficient today than at any other time in history. Boilers and diesel engines are designed to extract the greatest possible amount of energy from the fuel and to turn that energy into work. Turbines, generators and auxiliary equipment are designed to make the most effective use of the steam or mechanical energy that is supplied to them. Efficient operation of the marine power plant depends significantly on the quality of the water that it receives. Contaminants such as dissolved minerals, gases, oil, and even the water itself can cause serious damage to power plant equipment unless proper control steps are taken. Testing is an important part of any water treatment program because the test results are the primary means of controlling the program and of detecting problems. All test procedures are described in this manual after discussion of the applicable treatment program. We refer the reader to the section entitled "General Information" which should be read before conducting tests. Here, recommendations are provided for proper sampling, general testing and recording techniques.
