Delivering Essential Performance for Advanced RO Systems
Reverse osmosis is a critical part of the world’s water supply, and for most RO plants, the key word
is energy. Given the tremendous volume of water processed by RO plants, as well as the extremely
high energy costs, even small improvements in efficiency can translate into large savings or
increased product water output. You can trust SWM to provide the highest quality media options to
minimize pressure drop, biofouling, and overall energy needs. The SWM feed spacers, membrane
backing substrates, permeate core tubes, and machined parts work together to provide energy
savings for spiral wound membrane producers.
