Application of Corrosion Control Techniques in Municipal Water and Waste Water Engineering

The water and waste water treatment plants as well as the water distribution and sewage collection pipes are subjected to corrosion resulting in reduced efficiencies and even breakdown in extreme cases. The techniques of corrosion control are perhaps better known to the chemical industry and it is possible to adopt them in the held of public health engineering also. It is necessary for public health engineer to adopt proper remedial measures against corrosion in order to avoid major repairs, replacement and the resulting breakdown in the essential public utilities. The purpose of this paper is to acquaint the public health engineer with the various corrosion problems in this field, by indicating the problem areas and the available methods of prevention and cure.
