Color Instruction Green: Feed Wate Blue: Permeate Red: Seals and O-rings On this ST module the feed is from the top. The feed water is diffused by the top seal plate to send the feed water evenly around the top of the membrane element. The feed water flows down through the membrane element, as it does pure water permeates and flows out thourgh centre collection device into the space around the tie rod and flows down to the permeates outlets. The concentrated feed water is channelled by the bottom seal plate to the bottom HP connection and out of the module. |
