## Indications for use
The AmeniWater MediQA Reverse Osmosis System is one component of a water treatment system designed to pre-treat and purify potable water using reverse osmosis for making dialysate for hemodialysis applications. The device is intended to be a component in a complete water purification system, and is not a complete water treatment system. It must be preceded by pre-treatment devices, and may need to be followed by post-treatment devices as well to meet current AAMI and Federal (U.S.) standards. The Amen Water MediQA is intended for use in water rooms in a hospital, clinic, or dialysis center. The device includes an integrated heat sanitization process. The MediQA is available in both single pass and double pass models that supply from 4.5 to 12.0 gallons per minute (gpm) of product water. Model MSP1 is a single pass, single membrane RO that produces up to 5.0 gpm of product water. Model MSP2 is a single pass, dual-membrane RO that produces up to 9.4 gpm of product water. Model MSP3 is a single pass, 3-membrane RO that produces up to 12.6 gpm of product water. Model MOPi is a double pass, 2-membrane RO that produces up to 5.0 gpm of product water. Model MDP2 is a double pass, 3-membrane RO that produces up to 7.0 gpm of product water. Model MDP3 is a double pass, 4-membrane RO that produces up to 10.0 gpm of product water. Model MDP4 is a double pass. 5-membrane RO that produces up to 12.0 gpm of product water.
