P Pack S2 Pre-Purification Cartridge

Overview

The P Pack S2 Pre-Purification Cartridge is a high-integrity, replaceable filtration module engineered for integration into ultra-pure water (UPW) systems used in analytical laboratories, pharmaceutical QC environments, and semiconductor-grade water distribution networks. Designed as the first-stage purification component in multi-tiered water purification architectures, the S2 cartridge targets particulate matter, colloidal silica, residual chlorine, organic contaminants, and microbial byproducts upstream of downstream polishing stages—including reverse osmosis membranes, ion exchange resins, and 18.2 MΩ·cm final polishing units. Its function is grounded in depth filtration combined with activated carbon adsorption and graded polypropylene microfiber matrix technology—enabling consistent removal efficiency across variable feedwater qualities while maintaining low differential pressure and extended service life.

Key Features

• Multi-layer composite media: Outer pre-filter layer (≥5 µm nominal retention) removes suspended solids; inner activated carbon bed (coconut-shell derived, acid-washed) reduces chlorine, chloramines, TOC, and low-MW organics; final sub-micron support layer ensures particle shedding control.
• Chemically resistant housing: Polypropylene (PP) body rated for continuous operation at ≤45 °C and ≤0.6 MPa operating pressure; compatible with standard UPW system manifold interfaces (1/4″ NPT or DIN 16924).
• Pre-validated performance: Each batch undergoes integrity testing per ASTM F838-22 (bacterial challenge with Brevundimonas diminuta) and extractables profiling per USP <661.1>; endotoxin release <0.001 EU/mL per ISO 15707.
• Trace-metal–controlled construction: Housing and media fabricated in Class 10,000 cleanroom environment; heavy metal leachables (e.g., Fe, Ni, Cu, Zn) quantified via ICP-MS and confirmed below 10 ppt in eluate.
• Integrated RFID tag (optional): Enables automated usage tracking, replacement scheduling, and audit-ready log generation compliant with FDA 21 CFR Part 11 requirements when paired with compatible UPW system controllers.

Sample Compatibility & Compliance

The P Pack S2 cartridge is validated for use with municipal tap water, softened feed, and RO-permeate streams feeding Type I ultrapure water systems per ISO 3696:1987 and ASTM D1193-20. It meets material biocompatibility requirements per USP <88> (Class VI) and complies with RoHS Directive 2015/863/EU. While not intended for sterilizing-grade applications, it supports GLP and GMP water system qualification protocols—including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ)—when installed as part of a documented purification train. End-user responsibility includes verification of feedwater quality (e.g., SDI <3, free chlorine <0.1 mg/L) prior to installation to ensure optimal cartridge longevity and downstream system protection.

Software & Data Management

When deployed with Deepflow’s CY-Series UPW platforms (e.g., CY-UPW-2000, CY-UPW-5000), the S2 cartridge interfaces with the embedded AquaTrack™ control firmware. This enables real-time monitoring of cumulative flow volume, pressure drop delta (ΔP), and predictive end-of-life alerts based on historical throughput and inlet water quality logs. All operational data—including cartridge serial number, installation timestamp, and calibration references—is stored in an encrypted SQLite database with configurable export to CSV or direct integration into LIMS via OPC UA or Modbus TCP. Audit trails comply with ALCOA+ principles and support full traceability during regulatory inspections under ISO 9001, ISO 13485, or EU Annex 11.

Applications

• HPLC and UHPLC mobile phase preparation where TOC <5 ppb and particle count <1 particle/mL (>0.2 µm) are required.
• Cell culture media formulation and buffer preparation in biopharmaceutical manufacturing suites.
• Calibration standard dilution in clinical chemistry analyzers and ICP-MS sample introduction systems.
• Feed protection for EDI modules and UV oxidation reactors in semiconductor fab UPW loops.
• Pre-filtration for laboratory-scale LC-MS source cleaning protocols and column reconditioning workflows.

FAQ

What is the recommended service life of the P Pack S2 cartridge?
Typical service life ranges from 6 to 12 months depending on feedwater quality, flow rate, and total processed volume—typically specified as 10,000 L at ≤2 L/min under ISO 3696 Grade 3 inlet conditions.
Can the S2 cartridge be autoclaved or steam-sterilized?
No. The polypropylene housing and carbon media are not designed for repeated thermal sterilization; steam exposure may compromise structural integrity and adsorption capacity.
Is the cartridge compatible with ozone-treated feedwater?
Yes, provided residual ozone concentration remains below 0.05 mg/L at point of entry; higher concentrations accelerate carbon oxidation and reduce TOC removal efficiency.
Does Deepflow provide certificate of conformance and test reports?
Yes—each unit ships with a CoC referencing ISO/IEC 17025-accredited test data, including bacterial retention, endotoxin release, and elemental leachables profiles.
How should spent cartridges be disposed of?
Spent units must be treated as non-hazardous solid waste per local regulations; activated carbon content requires landfill disposal in accordance with EPA 40 CFR Part 261 guidelines for spent adsorbents.
