RO-HD20,RO system function descriptions

  No. of dialyzer

10~15 beds of dialysis machine

   1. RO water product    RO product  600 LPHat 25℃ , recovery rate ≧  50 %
   2. RO water quality

RO membrane TFC- 4040 , high permeate  , high rejection rate ≧ 99% ( single element )

RO water quality comply with AAMI  standard

   3. Anti-bacterial growth


1. RO water go through 253.7 nm UV lamp radiation, UV dosage ≧  30,000μw.s/cm2

2. After UV radiation the death body of bacterial then through  U/F element drain end flush out

  Thus RO water become bacterial free and safety feed to dializer

3. RO water go back to storage tank through UV lamp radiation and 0.2μm filter to prevent reverse

   contamination from return side。

4. There are optional of auto OZONE sterilizer perform disinfections at mid-night

   4. Ro water circulation

Ro water storage in a stainless steel tank and circulation pump delivery RO water to dializer

It can be one circulation loop,or 2 loops on optional。

   5. Piping matreial

The piping material are : SCH-80 PVC or Clean PVC

The outlet to dialysis machine : stainless steel 1/2 ”valve with snap connection adaptor

   6. Power control panel

   Power operation panel with PLC control auto operation,and option of POD monitoring 

    control ,including alarm remote monitor and controlprinting ...etc

7. RO system disinfections


The disinfections including RO membrane and the pipe line to dialyzer ,there are 2 methods:

   1. Hot water disinfections

   2. Chemical agent disinfections   

8.  2-pass RO system

Tap water TDS 1,000 mg / L,  recommend to choose 2-pass RO system
