Methods of equipment selection

The charts, tables and general information contained in categories (a)-(d) can be used as guides towards an initial selection of solid/liquid separation 

It is clear that there has previously been no accepted standard approach to solid/liquid equipment selection. With the now widespread availability of personal computers, however, the development of computer software is an ideal way to solve the problem of equipment selection. While rule-based expert systems appeared to provide the optimum solution at first, it became apparent to some researchers that inherent restrictions would prevent their widespread application. Thus, interactive personal computer software, partly based on an expert system approach, was developed to corrrmercial standards (i.e. p -SELECT, Tarleton and Wakeman, 1991 see also Wakeman and Tarletorr, 1991a) and further adapted for incorporation within FDS (Filter Design Software, 2005). The philosophies, charts, tables and knowledge used are described in the remainder of this section.

Some of the material which follows points out industrial methods of equipment selection where manufacturer contact and bidding are involved. This is inserted for completeness and to orient young engineers just starting out in this work.
