Blue Spring Corporation manufactures pharmaceutical usp water systems
Blue Spring WP-35USP skid-mounted usp water system
Ideal For Medium-sized and Large Pharmacies, Small Pharmaceutical Manufacturers, Dietary Supplement Producers, University Research Laboratories, Pharmaceutical Research Laboratories, Implantable and Non-implantable Medical Device Processing, Implantable and Non-implantable Medical Device Rinsing
Blue Spring Corporation is the pioneer (1982) in commercialization of double-pass reverse osmosis
technology for the production of Water for Injection per United States Pharmacopoeia.  Now, with the addition
of portable ion-exchange deionizer, the WP-35USP unit allows production of Purified Water and Water for
Injection, meeting the latest USP 32 standards
The WP-35USP system produces 90 LPH of USP Purified Water on continuous basis. The Purified Water may
be stored in the storage tank (supplied with the unit).  For larger on-line, continuous availability of USP Purified
Water, please consider Blue Spring WP-EDI series USP Water for Injection systems.  The USP Purified water
stored in the tank may be passed through the reverse osmosis unit once again, to further purify it to USP
Water for Injection standards. For larger capacity requirements and for on-line, continuous availability of USP
Water for Injection, please consider Blue Spring WFI-EDI series USP Water for Injection systems.

Output Water Quality
First- pass output water meets USP Purified Water standards.  Typical electrical
conductivity 0.2-1 microS/cm, typical TOC 120-200 ppb, Typical bacteria count 1-10 cfu/ml

Second-pass output water meets USP Water for Injection standards.  Typical electrical
conductivity 0.2 - 0.8 microS/cm, typical TOC 100-150 ppb, Typical bacteria count 1-10
cfu/100 ml.  Typical endotoxin level <0.125 EU/ml.

Note: Day-to-day biological quality of water will vary, depending on sanitizing and cleaning
schedule, and general equipment maintenance.
Supply Water and
1 GPM (3.7 LPM) of EPA drinking water quality municipal water, 15 -60 psig pressure, 15 -
32 oC water temperature.
* Intended for formulation of pharmaceuticals and pharmaceutical ingredients, and for manufacturing of
medical devices.  Water purification equipment not intended for direct use as a medical device in medical
treatment.  Product water not intended for direct use as a drug in medical treatment.  On-site Installation
Qualification, Operational Qualification, Performance Qualification and long-term System Validation is
usually required, for establishing long-term consistency of product water quality, under seasonal variations
of feed water quality and operating conditions.
