Some treatment plants can lagoon their sludge; others may dump it into nearby water “repositories.” The Albany, N.

Solution to its problem boiled down to two possibilities: dewater by rotary‐vacuum precoat filtration or natural freezing. Here is an extended report on the first and a partial one on the second.
