Theoretical and practical aspects application of internally staged design (ISD) application are considered. ISD is based on the usage of the different types of membrane elements in one pressure vessel when designing of the multi-stage reverse osmosis plants. The experience of such an approach when replacing of 144 elements in the actual RO plant is described. Several designs based on use of various combinations of the RO elements where carried out.
Described experience acknowledges an efficiency of the ISD approach. Significant increase of double-stage RO plant’s capacity and operational costs savings are proven in practice on the stipulation of acceptable permeate quality.
