In the lime-soda ash softening process, coagulants are used to gather which substances into particles that settle readily?

In lime-soda ash softening the goal is to remove hardness by forming solid precipitates from calcium and magnesium. The lime and soda ash create very fine calcium and magnesium precipitates, and these tiny particles wouldn’t settle well on their own. Coagulants are added to bridge and aggregate those fine precipitates into larger, settleable particles. So the substances being gathered into particles that settle readily are the fine calcium and magnesium precipitates. The resulting larger particles may be referred to as floc, but the key point is that the coagulants act on the fine precipitates to form settleable material.
