Simplified Ionic Representation of Industrial Water Streams

Industrial focus on environmental impact involves exploitation of internal resources. Water reuse is one of the topic and some characteristics have to be measured in order to evaluate the quality of a process water stream. Analytical estimation of water main properties becomes fundamental when preliminary study about reuse feasibility is required. This kind of evaluation for properties such as pH, electrical conductivity, Langelier Saturation Index, etc. Depends on ionic composition of the solution. A simplified Excel-based model has been developed in order to represent the ionic composition of an industrial water stream, which allows user to obtain approximate but realistic values for some properties of interest. The paper presents the approach to the model development with main assumptions and results.
