Grit removal is not included as a preliminary treatment step in most small wastewater treatment plants. Comminutors are sometimes adopted to supplement coarse screening and serve to reduce the size of large particles so that they will be removed in the form of a sludge in subsequent treatment processes.

Lesson 10: Softening

In natural water systems calcium carbonate is usually present and responsible for different characteristics of the water. Both hardness and alkalinity are expressed as a concentration of calcium carbonate (CaCO 3 ) for convenience of reporting a single nuer to represent multiple chemicals and for ease in calculating a solution''s carbonate and noncarbonate hardness.
