- aggregate
broader term — any collection of particles, not necessarily loose or suspended in liquid
- clump
less technical, more general — a clump may be dry or form in any medium
- flocculant
not a synonym — this is the substance added to cause flocs to form, not the cluster itself
文法句型
floc + of + [material]
用法筆記
Technical term used mainly in water treatment, wastewater engineering, and chemistry. The plural form flocs is far more common than the singular, since the process typically produces many clusters at once.
