Select one membrane industrial separation application for (i) reverse osmosis (RO), (ii) ultrafiltration (UF) and (iii) microfiltration (MF) (at least one of the three (in total) applications should be for environmental impact prevention or clean-up). For each of the three applications, describe and discuss the type of membrane and the configuration used. In your discussion, include major associated equipment in the separation process circuit, and the key operational parameters that need to be controlled and monitored. In your discussions, also outline what design factors need to be considered when deciding to use a membrane in preference to at least one other (non-membrane) separation method that could be also used to produce a similar endresult.
