Abstract
A liquid treatment plant has sets of membrane trains and processing trains with flow between them through channels. Flow configurations for withdrawing permeate and sludge from the trains are described. Cyclic aeration is provided to the membrane trains. Methods of foam control, backwashing and chemical cleaning are described. Single membrane trains or process trains may be isolated for various functions. An isolated membrane train may be used to thicken sludge.
