USP purified water with double-pass osmosis and EDI for Qualipharm
We designed, supplied, installed and commissioned a high-purity system with double-pass reverse osmosis, electrodeionization (EDI) and UV disinfection that turns well water into purified water in accordance with the USP and WHO Technical Report 37.

Well water turned into pharmaceutical-grade water
Qualipharm needed to generate purified water continuously, with demanding physicochemical and microbiological specifications, from well water and with certified sanitary materials.
- Conductivity below 1.3 µS/cmThe USP limit for purified water.
- Certified materialsSanitary components with material, weld and welder certification.
- Continuous productionDouble-pass reverse osmosis and EDI working in series.
From the well to purified watercapacity of each stage, in m³/day
Double-pass reverse osmosis removes most of the salts and EDI continuously polishes the permeate. The bars are proportional to the capacity of each stage.
- 3 membranesDow Filmtec in double pass
- 97 %EDI recovery
- 75 psimaximum EDI pressure
- < 1.3 µS/cmpurified water conductivity
Treatment train: from the well to purified water
Six stages with certified sanitary instrumentation: pretreatment, a double membrane barrier and final disinfection.
- Sediment filtrationFiberglass tank with aluminosilicate media and automatic backwash valve.Larger than 5 µm
- MicrofiltrationGradient polypropylene filter that protects the membrane stages.From 25 to 1 µm
- Chemical dosingGrundfos dosing pump with injector and 110 L tank, with a level sensor for the chemical alarm.ORP and pH at the inlet
- Double-pass reverse osmosisThree membranes, high-pressure pump and stainless steel skid, with sanitary bypass valve and automatic flushing.8.7 m³/day
- Electrodeionization (EDI)Sanitary module with material certification, 97% recovery and 75 psi maximum pressure.8.2 m³/day
- Final UV disinfectionSanitary UV with clamp connections, digital ballast with alarms and online intensity sensor.Final disinfection
Automation and control
- PLC with 4.3″ HMI touch screen connected to real-time sensors.
- Rosemount Emerson analyzers for ORP and pH on the inlet line.
- Online sanitary conductivity and pH in the product water, with level, pressure and flow alarms.
- Material certification
- Certified welding
- 316L stainless steel
- Clamp connections
