 The design, sizing and pricing of a Brackish water purification plant is highly specific to the application. A water analysis is required before the design can be confirmed. Based on the water analysis, consideration must be given to the necessary prefiltration that is required before the R/O unit, and post treatment necessary for the application.
In addition, the water analysis will determine the type, number and configuration of the membranes and the pumps and motors.
As a guideline, sizes and designs are shown below.
