Structure and Key Elements of a Water Treatment System for Hemodialysis

by Rio Ocampo

System Overview of a Water Treatment System

Ensuring the delivery of ultrapure water in hemodialysis facilities is critical for patient safety and clinical effectiveness. The following describes a typical water treatment system configuration, based on the schematic diagram provided above.

1. Pre-Treatment

Prepares feed water by removing particles, chlorine, and hardness that could damage RO membranes.

Component

Purpose

Sediment Filter/Activated Carbon/Softener

Conditions the city water for membrane treatment

 

2. RO-EDI Skid

The core purification unit. Reverse Osmosis (RO) removes up to 99% of dissolved solids and bacteria. Electrodeionization (EDI) further polishes the water to achieve ultrapure quality.

TechnologyFunction
RORemoves salts, microbes, endotoxins
EDIEnsures ultra-low conductivity

 

3. Sterile Distribution Loop

A hygienic, closed-loop system circulates purified water to all dialysis stations, minimizing contamination. Made from high-grade materials like PVDF or stainless steel to maintain sterility and resist biofilm buildup.

 

4. Hemodialysis Machine Area

Each machine receives sterile water for dialysate preparation. Water quality must meet the most stringent microbiological and endotoxin limits.
