High Purity Water (HPW) & WFI Generation
Pharmaceutical-Grade Systems with <1.3 µS/cm Conductivity and Thermal Sanitization.
Validatable Multi-Stage Process
Our 'Ionic' multistage approach is designed for microbial control and chemical purity through redundancy.
Pre-treatment & Softening
- Removal of hardness ions (Ca²⁺, Mg²⁺) to prevent scale.
- Activated Carbon / Ultrafiltration for chlorine and organics removal.
Double Pass Reverse Osmosis (DPRO)
- Pass 1: Removes >99% of dissolved salts, bacteria, and pyrogens.
- Pass 2: Polishing barrier reducing conductivity further.
- High recovery rates (75-85%) with low-energy membranes.
Continuous Electro-Deionization (CEDI)
- Electric regeneration of resin beds – Zero Acid/Caustic chemicals.
- Target Output: Resistivity 10–18 MΩ·cm.
Ultrafiltration (UF) Polishing
- Final endotoxin barrier for WFI limits (< 0.25 EU/ml).
- 6,000 Daltons MWCO for effective pyrogen reduction.
