Integrated Purified Water Generation & Distribution Systems for Pharma, Electronics & Industry
LENO TANK provides complete, validated, and modular systems for the production, storage, and distribution of Purified Water (PW) and Water for Injection (WFI) compliant with global pharmacopoeias (USP, EP, ChP), as well as high-purity water for electronics and fine chemicals. Our solutions are engineered to ensure consistent water quality, operational reliability, and compliance with stringent industry standards from the source water inlet to the final point of use.
Core Process Stages & LENO TANK Equipment Integration:
| Production Stage | Process Objective & Key Challenge | Recommended LENO TANK Equipment | Key Value & Advantage |
|---|---|---|---|
| 1. Pretreatment & Primary Filtration | Remove suspended solids, chlorine, organics, and hardness to protect downstream RO membranes and ion exchange resins. | Multi-Media Filters, Activated Carbon Filter Housings, Softeners, Basket/Pre-filters | Robust pretreatment skids protect the high-value core purification stages. Activated carbon removes chlorine and organics. Basket filters capture particulates, ensuring SDI (Silt Density Index) is within membrane limits. |
| 2. Core Purification / Desalination | Remove dissolved ionic contaminants to achieve the required conductivity/resistivity. This is the heart of the system. | Reverse Osmosis (RO) Skids, Electrodeionization (EDI) Stacks | We integrate and supply balance-of-plant equipment for RO/EDI systems, including high-pressure pumps, sanitizable RO membrane housings, and clean-in-place (CIP) units. Our systems are designed for optimal recovery and salt rejection. |
| 3. Polishing & Final Conditioning | Achieve ultra-high purity (≥18.2 MΩ·cm), remove TOC (Total Organic Carbon), and ensure microbial control. | Mixed Bed Ion Exchange (MB) Polishers, Ultraviolet (UV) Sterilizers, Final 0.1/0.2 μm Filters | MB polishers provide the final ionic purity. 254nm & 185nm UV lamps sterilize and reduce TOC. Ultrafine cartridge filter housings provide absolute microbiological security before distribution. |
| 4. Hot Storage & Circulation (for WFI) | Maintain WFI at >80°C in storage and >65°C in a circulating loop to prevent microbial proliferation, as per pharmacopoeial guidelines. | Insulated Pure Steam Heated Storage Tanks, Distribution Pumps, Heat Exchangers | Jacketed storage tanks with pure steam or electrical heating maintain temperature. Sanitary centrifugal pumps ensure turbulent flow in the loop. Plate heat exchangers provide cooling at points of use while maintaining loop temperature. |
| 5. Ambient Storage & Distribution (for PW) | Store and distribute Purified Water without a hot loop, relying on continuous circulation and sanitization cycles. | Sanitary Storage Tanks, Distribution Pumps, UV & Ozone Sanitization Systems | Stainless steel tanks with hydrophobic vent filters. Systems are designed for dead-leg-free distribution and can be integrated with ozone or hot water sanitization cycles. |
| 6. Monitoring & Control (QC) | Continuously monitor key parameters (TOC, Conductivity, Flow, Pressure, Temperature) and automate sanitization cycles. | Integrated PLC/SCADA Systems, In-line Sensors, Data Logging | We provide full automation with validated control systems for data integrity (FDA 21 CFR Part 11 compliant). Real-time monitoring ensures water quality is always within spec and triggers alarms or sanitization automatically. |
Why Choose LENO TANK’s Purified Water Solution?
Compliance by Design: Our systems are engineered from the ground up to meet GMP, USP <643> TOC, <645> Conductivity, and <1231> Water for Pharmaceutical Purposes requirements. Material certifications, surface finishes (Ra < 0.6 μm), and welding documentation (ASME BPE) are provided.
Validated & Turn-Key Delivery: We deliver more than equipment—we deliver a validated system. Our scope includes IQ/OQ/PQ documentation support, 3D design, and performance qualification protocols to ensure the system meets all user requirements (URS) from day one.
Focus on System Hygiene & Sanitizability: Every component—from tank internals to pipeline valves—is selected for drainability and cleanability. Our designs prioritize eliminating dead legs and incorporate integrated CIP/SIP (Clean-in-Place/Sterilize-in-Place) capabilities, which are critical for maintaining microbial control.
Scalable & Modular Approach: From compact point-of-use (POU) purification units for labs to multi-ton-per-hour central utilities for large manufacturing plants, we offer modular designs that allow for capacity expansion and technology upgrades with minimal disruption.
