Technical Features
The system utilizes fully automatic control (manual control is also available), and automatic backwashing and regeneration programs can be set during system operation.
Primary reverse osmosis (RO) and secondary RO are fitted with return pipes; the RO equipment comes with chemical cleaning devices and disinfection devices.
A pH adjustment device is installed between primary RO and secondary RO to guarantee that the water conductivity of the equipment meets pharmacopoeia requirements.
The secondary RO membrane adopts a positively charged anti-pollution RO membrane, ensuring stable long-term operation of the RO equipment.
Primary RO pipelines use 304 stainless steel, while secondary RO pipelines use 316L stainless steel.
Both primary and secondary RO equipment are equipped with online conductivity detection instruments, allowing real-time monitoring of produced water conductivity.
A low-pressure protection switch is installed before primary RO; both low-pressure and high-pressure protection switches are installed before secondary RO.
The water recovery rate of primary and secondary RO is adjustable: primary RO recovery rate ranges from 60% to 65%, and secondary RO recovery rate is 70%.
The purified water storage tank is fitted with a breather filter; the delivery pipeline is equipped with an ultraviolet sterilizer and a microporous filter to ensure purified water meets hygiene requirements.
Online water quality detection function enables real-time understanding of water quality.
PLC-based fully automatic control, with a user-friendly operation and display system; the equipment can be operated with a single button, and is equipped with tap water cutoff protection and full-water shutdown functions.
The system performs automatic flushing when started, eliminating the need for manual flushing and effectively prolonging the service life of RO membranes.
Elegant and exquisite appearance; safety and insulation performance meet GLP safety requirements.
Real-time display of flushing, water production, full-water, water-shortage, and maintenance status, with sound and light alarm functions.
Adopts modular and quick-connect design, facilitating installation and maintenance, requiring a small footprint, and making upkeep more convenient.
The RO membrane equipment has a scheduled automatic flushing program when started, with functions including startup self-inspection, water-shortage protection alarm, automatic reset after power failure, and low/high-pressure protection.
The structural design should be simple in structure, reliable in performance, and easy to disassemble and assemble.
To facilitate disassembly, replacement, and cleaning of parts, the actuator design should prioritize standardized, universal, and systematic components.
The inner and outer wall surfaces of the equipment should be smooth and flat, free of dead zones, and easy to clean and sterilize. Part surfaces should be chrome-plated for corrosion resistance and rust prevention. Paint should not be used on the equipment exterior to avoid peeling.
Equipment for purified water preparation should use low-carbon stainless steel or other materials verified to be non-polluting to water quality. Such equipment should be cleaned regularly, and the cleaning effect should be verified.
Materials in contact with water for injection must be high-quality low-carbon stainless steel or other materials verified to be non-polluting to water quality. Equipment for water for injection preparation should be cleaned regularly, and the cleaning effect should be verified.
The storage period of purified water should not exceed 24 hours. Its storage tank should be made of stainless steel or other materials verified to be non-toxic, corrosion-resistant, and non-leaching of pollutant ions. A hydrophobic sterilizing filter (non-fiber-shedding) should be installed to protect its vent. The inner wall of the storage tank should be smooth; pipes and welds should have no dead zones or pinholes. Sensors for displaying parameters (e.g., liquid level, temperature, pressure) that do not cause stagnant water pollution should be used. The storage tank should be cleaned, disinfected, and sterilized regularly, and the cleaning/sterilization effect should be verified.
This equipment is applicable to biological preparations, in vitro diagnostic reagents, medical devices, pharmaceutical industry, health products, oral liquids, cosmetics, food, medical large infusions, pharmaceutical preparations, genetic engineering, water for kidney dialysis, disinfectants, eye drops, non-woven fabrics industry, and medical and health supplies (such as gauze, mouthpieces, wet wipes, protective clothing, medical gloves, diversion tubes, etc.).
It complies with the purified water standards in the 2020 Edition of Chinese Pharmacopoeia GMP, EU and FDA GMP specifications and implementation guidelines, JB/T20194-2019 (Medicinal Purified Water Preparation Equipment), and GB50913-2013 (Design Specification for Pharmaceutical Process Water Systems).
The system features automatic control, with simple operation and convenient management. Equipped with an intelligent automatic controller, the equipment offers advantages including simple and convenient operation, stable water quality, low operating costs, environmental friendliness, and easy maintenance.
