Sartorius, H2O-CRO-H-2, Arium® Advance EDI | Comfort II Reverse Osmosis Modules

Arium reverse-osmosis modules are replacement membrane components for Arium Advance EDI and Arium Comfort II laboratory water purification systems. The modules provide a reverse-osmosis treatment stage that reduces dissolved salts, microorganisms, organic contaminants and fine particles in feed water. Their specified nominal production capacity is 10 L/h under the applicable system conditions. Reverse osmosis relies on pressure-driven transport of water through a selective membrane while contaminants are preferentially retained in the concentrate stream. Good pretreatment and hardness control are important to protect the membrane from oxidants, fouling and mineral scaling. The modules are designed for the indicated Arium systems and are provided as a two-unit replacement pack. They should not be confused with the preceding activated-carbon prefilter or softener cartridge, which address different classes of contaminants. Replace membranes in accordance with system performance indicators and maintenance instructions, and check the water quality after recommissioning.
