Overview
The Deepflow CYCDAQPP1 is a dedicated pre-filtration module engineered for integration into multi-stage ultra-pure water (UPW) production systems. It serves as the primary mechanical barrier for municipal tap water feed streams, removing suspended particulates, rust flakes, colloidal matter, and macro-scale organic debris prior to downstream purification stages—including activated carbon adsorption, reverse osmosis (RO), ion exchange, and final ultrafiltration or UV oxidation. The system employs a dual-stage cotton core filtration architecture: six 1 µm-rated pleated polypropylene (PP) cotton cores provide fine particulate retention, while six 10 µm-rated cores handle high-capacity gross sediment removal. This staged configuration ensures extended service life, balanced pressure drop distribution, and minimized risk of premature clogging in sensitive downstream components such as RO membranes or mixed-bed resins.
Key Features
- Dual-grade filtration architecture: Independent 1 µm and 10 µm cotton core banks enable optimized contaminant stratification and load sharing.
- High-flow, low-differential-pressure design: Each cotton core is wound from food-grade polypropylene fiber with uniform pore structure, delivering consistent flow rates up to 3.2 L/min per core at ≤0.15 bar ΔP (tested at 25°C).
- Modular cartridge housing: Standard 10-inch (254 mm) length, 2.75-inch (69.8 mm) diameter housings conform to ANSI/NSF Standard 58 and ISO 9001-compliant manufacturing protocols.
- Chemical compatibility: Resistant to chlorine, chloramines, and common oxidants present in municipal water supplies; compatible with pH 3–11 operating range.
- Trace metal leaching control: All wetted materials certified to meet ASTM D1193 Type I specifications for low extractables, ensuring no introduction of Na⁺, Ca²⁺, Fe³⁺, or SiO₂ into the purified stream.
Sample Compatibility & Compliance
The CYCDAQPP1 is validated for use with potable water sources meeting WHO Guidelines for Drinking-water Quality and China’s GB 5749–2022 standards. It is not intended for raw surface water, well water, or wastewater influent without upstream coarse screening. As a pretreatment component—not a standalone purification device—it complies with ISO 3696:1987 (Water for analytical laboratory use) as part of a certified UPW system architecture. When installed in validated water purification trains, it supports compliance with USP , EP 2.2.43, and CLSI GP38-A3 requirements for particle control in reagent water used in clinical chemistry, HPLC mobile phase preparation, and cell culture media formulation.
Software & Data Management
This is a passive mechanical filtration module with no embedded electronics, sensors, or firmware. No software interface, data logging, or connectivity is provided. Maintenance tracking—including cartridge replacement intervals, differential pressure monitoring, and service history—must be performed manually or integrated via external building management systems (BMS) or facility SCADA platforms using optional analog pressure transducers (e.g., 4–20 mA output). For GLP/GMP environments, users are advised to document cartridge lot numbers, installation dates, and end-of-life criteria (typically ΔP ≥ 0.3 bar or >6 months service life) in accordance with internal SOPs aligned with FDA 21 CFR Part 11 audit-trail principles.
Applications
- Front-end protection for laboratory-scale RO systems (e.g., Milli-Q IQ 7000, ELGA PURELAB Chorus)
- Pre-filtration for central UPW distribution loops in pharmaceutical QC labs and biotech R&D facilities
- Particulate mitigation in semiconductor fab tool rinse water sub-loops requiring ISO Class 5 cleanroom-compatible feed water
- Guard filtration for online conductivity and TOC analyzers to prevent sensor fouling
- Backup filtration redundancy in critical applications where single-point failure must be avoided
FAQ
What is the recommended replacement interval for the 1 µm and 10 µm cotton cores?
Cartridge replacement should be based on measured differential pressure (≥0.3 bar) or time-in-service (≤6 months), whichever occurs first. In high-turbidity municipal supplies, replacement may be required every 3–4 months.
Can these cotton cores be backwashed or regenerated?
No. Polypropylene cotton cores are single-use, non-regenerable elements. Attempted cleaning compromises structural integrity and filtration efficiency.
Is this module suitable for seawater or brackish water pretreatment?
No. The CYCDAQPP1 is rated exclusively for chlorinated municipal tap water. Seawater or high-TDS sources require corrosion-resistant stainless steel housings and specialized pre-filters compliant with ASTM D4195.
Does Deepflow provide validation documentation for this module?
Yes—certificates of conformance (CoC), material traceability reports, and filter efficiency test data (per ISO 16889:2018) are supplied with each batch shipment upon request.
How does this module integrate with existing UPW system alarms?
It does not integrate directly. Integration requires third-party pressure switches or transmitters installed upstream/downstream of the housing, linked to the main system PLC or alarm panel.
