PROflex – true flexibility to design a system you want PROflex offers the flexibility to choose a system that allows you to choose an aggressive or conservative design to meet the capital requirements of your specific situation. PROflex allows complete choice on arrays, number of elements, and pump sizes within each array. Figure 1 shows the PROflex product line and the flow ranges. The flow ranges are the hydraulic limits with each model. Users should choose their RO system by determining: 1. Desired permeate flow range Square footage of the membranes needed (or flux limits), per element Desired...

2Permeate ranges are stated at the foLLowing design conditions: 500 ppm TDS, 77.5% recovery, 60F, pump Listed, and using 400 ft AG elements. Your flow rate will vary greatly as you change temperature, elements and pump sizes and TDS levels. Consult SUEZ or Winflows for flows expected with your feed water conditions. 3 Recycle Rate will vary with flux and feedwater conditions. When to use recycle will depend on the tradeoff user wants to make between permeate quality and membrane element life/frequency of cleaning. Use Winflows to determine permeate quality. The base 2S models do not come with...
