摘要:
For three commonly used gases ‐ chlorine, sulfur dioxide, and ammonia ‐ maximum sustained gas withdrawal rates from shipping containers can be estimated using a simple equation. The equation requires that the operator know the room temperature, the “threshold temperature,” and a “withdrawal factor.” This article explains the terms of the equation and gives examples of its application.

摘要:
The first step in water quality analysis is collection of samples that accurately represent the quality of the water being sampled. In order for an analysis of a sample to be accurate, the characteristics of the water sample must remain unchanged. Proper sample preservation, transportation, and storage are discussed. This article is an excerpt from the AWWA publication Water Quality Analyses.

摘要:
Preventive maintenance can help to avoid unscheduled downtime. When equipment fails, it usually requires expensive crews and priority orders on labor and equipment. This article discusses how to set up a preventive maintenance program for chemical feeding equipment.

摘要:
Painting the pipes in the pipe galleries of water treatment plants and pump stations in order to make the pipes easier to identify is a good practice. Color coding helps to prevent possible errors when taking samples or performing maintenance. A table of suggested piping color codes is presented.

摘要:
Many treatment plants have synchronous motors driving the pumps. Occasionally, the motor slip rings require machining in place with a special lathe cutting tool and holder designed for that purpose. This machining operation can be simplified with the method described in this article.
