Feed and bleed (continuous) reverse osmosis (RO) is mainly used for removing ionic species and medium MW solutes from water solutions in plants that require large throughputs. Typical applications include water desalination and ultrapure water production. In the biotech field, RO filters have been used to concentrate and purify antibiotics.
● Filtrate: the designated output port for the filtrate.
● Concentrate: the designated output port for the concentrate.
The following operation types are currently supported in the context of this unit procedure:
