1m³/hour RO EDI Water System For HPLC Mobile Phase Preparation And Precision Laboratory Instruments

Customizable 1000 liters/h ultrapure water filtration system for mobile phase preparation for precision instruments

Overview
The 1000 L/H ultra pure water treatment system is designed to provide high-purity water for mobile phase preparation in precision analytical instruments, such as HPLC, LC-MS, ICP, and other laboratory or analytical applications.
The system adopts advanced purification technologies including pre-treatment, reverse osmosis, EDI (Electrodeionization), and polishing purification, ensuring stable production of ultra-pure water that meets the stringent requirements of precision instruments and laboratory analysis.

Process
Raw Water → Raw Water Pump → Multi-Media Filter → Activated Carbon Filter → Water Softener → Security Filter → First-Stage RO → Intermediate Tank → Second-Stage RO → EDI System → Polishing Mixed Bed → Ultra-Pure Water Tank → Circulation Pump → UV Sterilizer → 0.22 μm Terminal Filter → Point of Use

Main System Components

1. Pretreatment System

• Multi-media filter for removing suspended solids and turbidity

• Activated carbon filter for removing chlorine, organic matter, and odor

• Water softener for reducing hardness and preventing membrane scaling

2. Reverse Osmosis System

• Two-stage reverse osmosis system for high-efficiency desalination

• Removal of dissolved salts, heavy metals, and microorganisms

3. EDI System

• Continuous electrodeionization technology

• Produces high-purity water without chemical regeneration

• Stable operation and low operating cost

4. Polishing Mixed Bed

• Further removal of trace ions to achieve ultra-low conductivity

• Ensures ultra-pure water quality for sensitive analytical instruments

5. Storage and Distribution System

• Ultra-pure water storage tank (food-grade PE or stainless steel)

• Circulating distribution loop with UV sterilization and terminal filtration
