This Technical Report deals with methodologies for preparing synthetic suspensions. Synthetic suspensions can be used for: a) evaluating or testing new devices or techniques for suspension treatment; b) studying the influence of different compounds on suspension behaviour with regard to specific parameters, e.g. settleability, dewaterability, physical consistency, etc. The chemical, physical and biological characteristics of suspensions are subjected to changes as soon as they are collected. Guidance exists on the sampling and handling techniques (see ISO 5667 12 and EN ISO 5667 13), and on the preservation and storage procedures (EN ISO 5667 15) that help minimize changes in the composition. This is mainly achieved by suppressing chemical and/or biological activity and by avoiding contamination.
