Sartorius arium™ RO Module (advance RO and comfort I systems)

The RO modules are designed to produce up to 380 liters per day of RO permeate water. The low-energy TFC membranes require less energy (pressure) to produce a higher quantity of water/hour than comparable membranes of the same size. This reduces running cost by consuming less electric power.

The RO modules typically produce greater than 50% permeate recovery, which conserves water while still providing 99% or greater salt rejection. Each time the systems shuts down with a full tank, the RO membranes are backflushed with permeate water. Back-flushing with RO permeate water removes particles and potential scale forming salts from the membrane surface, promoting longer service life and reducing system maintenance.

This back-flushing operation allows the RO membranes to be stored in RO permeate water instead of feed or mains water between service operations, which extends the service life of the membrane. At startup, the system will produce higher quality permeate water as compared to conventional systems that store membranes in feed water.
