About Portable Reverse Osmosis System for Hemodialysis
Sizing a system? Send your flow rate and a feed-water analysis, and an AMPAC engineer will work out the configuration with you.
Short answer: Water for hemodialysis has to meet AAMI/ANSI 13959, which is stricter than drinking water, and the standard applies to the whole system: pretreatment, RO, storage and the distribution loop. This page lists one product, the APRO-DI15 (1,500 GPD). A clinic system is specified per site from the number of treatment stations and a feed water analysis, so request a quote with both. The FAQ below covers single-pass and double-pass RO and loop design.
The reverse osmosis (RO) system uses a pump to push water through a semipermeable membrane or filter which removes almost all of the contaminants including bacteria and viruses. The product water is the ultra pure water which enters the hemodialysis machine and is used to mix the dialysate for your dialysis treatment.
Water systems for dialysis clinics
AMPAC USA quotes reverse osmosis water systems for dialysis clinics. Meeting AAMI/ANSI/ISO 13959 is a property of the whole installed system, which the clinic validates on site; AMPAC USA does not claim that any model is validated for it. A quote starts from your station count, a feed water analysis and the loop layout. This page lists the APRO-DI15 (1,500 GPD); larger or double-pass systems are specified per site.

Frequently Asked Questions
What water quality standard governs water used in hemodialysis treatment?
AAMI/ANSI/ISO 13959 sets chemical, bacterial and endotoxin limits for water used to make dialysate. The limits are stricter than drinking water limits because patients are exposed to large volumes of water through the dialysate. The standard applies to the whole system, and the clinic validates it on site.
When is double-pass RO used for dialysis water?
In a double-pass system the permeate of the first RO stage feeds a second RO array, which improves rejection and endotoxin control. Whether a clinic needs single-pass or double-pass depends on its feed water and risk assessment, so confirm it with your water-system engineer.
How should a dialysis water distribution loop be designed?
Loops should circulate continuously, avoid dead legs where biofilm can form, and include sampling ports and a disinfection routine. Follow AAMI TIR34 guidance and your validation plan. Layout is specified per site.
How is a dialysis water system sized for a clinic?
Sizing depends on the number of simultaneous treatments, treatment duration and the dialysate flow of each machine. Send your station count and a feed water analysis. This page lists the APRO-DI15 (1,500 GPD); larger systems are quoted per site.
