2 m³/h 15MΩ·cm Chemical-Free Ultrapure Water System and RO EDI Water Purifier for Pharmaceutical Use

Manufactured by Howann, the 2 m³/h (2,000 L/H) RO+EDI Ultrapure Water System is engineered to meet the stringent water quality standards and cGMP guidelines of pharmaceutical formulation, electronic microchip rinsing, and high-precision chemical laboratories. Designed to replace hazardous acid-base chemical regeneration loops required by conventional ion-exchange beds, this advanced system utilizes electrical current to continuously regenerate ion-exchange resins inside an EDI module.

Constructed upon a sanitary SS304 stainless steel frame with electro-polished fluid pathways, the Howann ultrapure water station integrates dual-pass reverse osmosis, ultraviolet sterilization, and state-of-the-art EDI modules. This automated architecture ensures stable, uninterrupted delivery of 15MΩ·cm high-resistivity water, eliminating bacterial growth risks and drastically reducing overall utility and maintenance expenditures.

• High-Yield 2 m³/h (2,000 L/H) Capacity: Engineered to provide a continuous, reliable volume of ultra-pure water to support busy pharmaceutical production lines.
• Stable 15MΩ·cm Resistivity Output: Combined RO and EDI technology strips out trace ionic contaminants to consistently meet high electrical resistivity thresholds.
• 30% Lower Operating Expenses: Eliminates the purchase, storage, and neutralization of regeneration chemicals (HCl and NaOH) required by standard ion-exchange beds.
• Sanitary SS304 & PVDF Construction: Premium electro-polished stainless steel frames and smooth internal piping prevent biofilm accumulation and microbial growth.
• Fully Automated PLC Operation: Intelligent digital controls manage system startup, automatic EDI flushing, and continuous water quality logging without manual oversight.

• Pre-Treatment & Dual-Pass RO: Feed water undergoes multi-stage filtration and dual-pass reverse osmosis to eliminate 99% of dissolved minerals and particulates.
• Intermediate Storage & Boosting: Permeate water collects in a sanitary holding tank before being pressurized into the continuous electrodeionization module.
• EDI Electrical Regeneration: Direct current passes through ion-exchange resins and selective membranes, continuously pulling remaining ions out of the water and discharging them to waste.
• Ultraviolet Polishing & Distribution: Water flows through UV sterilization chambers (185nm/254nm) to destroy residual organics and bacteria before final delivery.

• Pharmaceutical Manufacturing: Purified water and water for injection (WFI) loop feed meeting strict pharmacopeia standards.
• Semiconductor & Electronics Cleanrooms: High-resistivity rinsing water for microchip component washing and circuit board fabrication.
• Analytical & Biotech Laboratories: High-purity reagent water for HPLC, mass spectrometry, and biological culture media preparation.
• Fine Chemical Processing: Ultra-clean process water preventing batch contamination in specialty chemical synthesis.

• Hot Water Sanitization Modules: Automated 80°C thermal sanitization loops for complete microbial control in pharmaceutical pipe networks.
• TOC Online Analyzers: Real-time Total Organic Carbon sensors for continuous water quality validation.
• Customized Flow Skid Capacities: Tailored throughput rates ranging from 0.5 m³/h up to 10 m³/h.
