flocculate

“The art, of course, is to have a large percentage of oil-producing algae and a very small percentage of those flocculating algae.”

But we must conclude as most probable that some action is at work in the sea water and in the salt solutions which clumps or flocculates the sediment.

In many cases, lime is very beneficial to land, usually because it corrects acidity and has a mechanical effect in pulverizing and flocculating clay and in cementing sands.

The washing would be very likely to have a decided flocculating effect and so render this material more friable when applied to the field.
