Solution

Liquid in which solid substances are dispersed in their finest physical form.

Suspension

Liquid in which finely dispersed solids are suspended, which in a state of rest may tend to settle (sedimentation) or float (flotation).

Emulsion

A mixture of liquids that normally do not mix.

Colloids

The finest particles, which, due to their small size, no longer behave like suspended particles in liquids, but float evenly distributed in the liquid.

Abrasiveness

Abrasive effect of suspended particles contained in a liquid. The size of the suspended particles is such that they can sediment or float.

dAggressivenessd

d

Corrosive effect of a liquid on other materials.

Permeate

Low-conductivity water produced by treatment using reverse osmosis.
