Product Details
In the development process of the medical industry, the quality of purified water, as the basic material, directly affects the safety and effectiveness of drug production, medical device cleaning, clinical testing and other links.Yan'an 2 tons/hour medical purified water equipmentWith the core goal of meeting the purified water standards of the Chinese Pharmacopoeia, we provide a stable and reliable high-quality purified water solution for the medical field through a full process precision process design of "pretreatment reverse osmosis (RO) - electro deionization (EDI) - post-treatment", combined with strict equipment configuration and quality control system. The following provides a detailed explanation from the aspects of core processes, technical parameters, equipment configuration, etc.
1、 Core process route: Multi link collaboration to ensure water quality safety
Medical purified water needs to meet extremely strict standards, such as conductivity ≤ 2 μ S/cm (25 ℃), microorganisms ≤ 100CFU/mL, endotoxins ≤ 0.25EU/mL, etc. Suzhou's 2-ton/hour medical purified water equipment adopts the mainstream process route of "pretreatment system reverse osmosis system electro deionization system post-treatment and sterilization", and each link closely cooperates to gradually improve water quality and ensure that the final output of purified water meets the high standards of the medical industry.
（1） Pre treatment system: pre barrier for raw water purification
The core task of the pretreatment system is to remove impurities such as suspended solids, residual chlorine, organic matter, and hardness substances from the raw water, reduce the pollution index of the raw water, provide high-quality influent for subsequent RO membranes and EDI modules, and effectively extend the service life of the core equipment.
Multi media filterThe multimedia filter adopts a layered filling structure inside, with the upper layer filled with quartz sand with a particle size of 0.5-1.2mm, used to intercept small particles; The lower layer is filled with smokeless coal with a particle size of 1-2mm, mainly to remove larger particle impurities. When the raw water passes through the filter layer from top to bottom, relying on the interception, precipitation, and adsorption of the filter material, suspended solids, colloids, and other impurities with a particle size of 5-10 μ m in the water can be effectively removed, significantly reducing the turbidity of the effluent and the suspended solids content, creating favorable conditions for subsequent treatment processes.
Activated carbon filterHigh quality coconut shell activated carbon is selected for filling, which has a rich microporous structure and a huge specific surface area (up to 1000-1500m ²/g), endowing it with * adsorption capacity. On the one hand, activated carbon can convert the highly oxidizing residual chlorine in raw water into harmless chloride ions through catalytic reduction, resulting in almost zero residual chlorine content in the effluent, effectively preventing residual chlorine from causing oxidative damage to the RO membrane; On the other hand, it can efficiently adsorb organic matter, pigments, and odorous substances in water, reduce the total organic carbon (TOC) content in water, and minimize the interference of organic matter on subsequent processes.
Softener (optional)When the hardness of the raw water is high (usually measured by the concentration of calcium and magnesium ions, if it exceeds a certain threshold, such as>100ppm), a softener needs to be configured. The softener is filled with sodium type ion exchange resin, which replaces calcium and magnesium ions in water with sodium ions in the resin through ion exchange reaction, effectively reducing the hardness of water, preventing the formation of scale on the surface of the RO membrane, and ensuring the stable operation and efficient desalination performance of the reverse osmosis system.
precision filterUsing a 5 μ m pore size polypropylene (PP) melt blown filter element, it can intercept residual small particles and impurities during the pretreatment process, such as broken filter media, flocs, etc., as the last protective barrier of the RO system, preventing particles from scratching the surface of the RO membrane and ensuring efficient operation of the RO membrane under good conditions.
（2） Reverse osmosis (RO) system: a key step in deep desalination
The reverse osmosis system is the core unit for achieving deep desalination of raw water. Through the selective permeation principle of RO membrane, it removes more than 99% of soluble impurities in water, providing high-quality influent for subsequent EDI treatment.
RO membrane groupDow BW30-400IG DRY membrane element is selected, which has anti pollution performance and high desalination rate. The desalination rate of a single membrane is ≥ 99% (test conditions: 25 ℃, 1500ppm NaCl solution). By reasonably configuring the number and arrangement of membrane components, ensure that the equipment achieves a stable water production of 2 tons/hour. The special structure of RO membrane allows water molecules to pass through under high pressure, effectively intercepting impurities such as salt, organic matter, bacteria, viruses, etc., thus achieving efficient desalination.
high-pressure pumpThe high-pressure pump made of 316L stainless steel material has good corrosion resistance and stability, and can provide a water inlet pressure of 1.0-1.5MPa for RO membrane filtration. The high-pressure pump is equipped with a pressure sensor and an automatic protection device. When the inlet pressure is below the set threshold (such as 0.1MPa) or the system pressure exceeds the safe value (such as 1.8MPa), it will automatically shut down and give an alarm to prevent equipment damage or membrane element rupture caused by abnormal pressure, ensuring the safe and stable operation of the system.
Recovery rate controlThe recovery rate of the RO system can be flexibly adjusted according to the TDS (total dissolved solids) of the raw water, usually controlled between 60-75%. By optimizing the ratio of concentrated water discharge and fresh water collection, while ensuring the quality of water production, we aim to maximize water resource utilization and reduce wastewater discharge. Meanwhile, a reasonable recovery rate setting helps maintain the water flow state on the surface of the RO membrane, prevent concentration polarization, and extend the service life of the RO membrane.
Water quality assurance for effluentAfter first stage reverse osmosis treatment, the effluent quality is significantly improved, the conductivity can be reduced to ≤ 20 μ S/cm (room temperature), and the pollution index SDI<3, providing reliable guarantee for the stable operation of the subsequent EDI system.
（3） Electrodeionization (EDI) system: advanced technology for deep desalination
The EDI system is a key technology for achieving high purity of purified water, which replaces traditional mixed bed processes with the synergistic effect of electrodialysis and ion exchange resins to achieve continuous deep desalination.
working principleUnder the action of a direct current electric field, the ion exchange resin in the EDI module adsorbs cations and anions in water, while the selective permeability of the ion exchange membrane enables directional migration of ions from the fresh water chamber to the concentrated water chamber, achieving deep desalination. This process does not require acid-base chemical regeneration. The hydrogen ions (H ⁺) and hydroxide ions (OH ⁻) generated by water electrolysis continuously regenerate the resin, which not only reduces operating costs and environmental pollution, but also stably produces high-purity purified water with a resistivity of ≥ 15M Ω· cm.
Device ConfigurationUsing EDI modules from Siemens or IONPURE, combined with a dedicated DC power supply system, the current density can be adjusted according to water quality conditions to optimize desalination efficiency. At the same time, high-precision resistivity online monitoring instruments are equipped to monitor the water resistance rate of the produced water in real time, ensuring stable and compliant water quality.
（4） Post treatment and sterilization system: the ultimate guarantee for improving water quality
UV sterilizerUsing a low-pressure mercury lamp with a wavelength of 254nm, the lamp power is precisely configured according to the flow rate (10-15 W power is required for processing 1m ³/h of water), ensuring that the ultraviolet radiation dose of the water flow in the equipment is ≥ 40mJ/cm ². Ultraviolet radiation destroys the DNA or RNA structure of microorganisms, causing them to lose their ability to reproduce and survive, with a sterilization rate of over 99.9%. It effectively kills residual bacteria, viruses, and other microorganisms in water, preventing secondary pollution during storage tanks and subsequent use.
Terminal polishing mixed bed (optional)For scenarios that require water purity, such as the preparation of injection water in the pharmaceutical industry, a terminal polishing mixed bed can be configured. The polishing mixed bed uses nuclear grade resin, which can further desalinate the EDI produced water and reduce the conductivity to ≤ 1 μ S/cm, meeting higher water quality requirements.
Aseptic water storage tankMade of 316L stainless steel material, the inner wall is polished to Ra ≤ 0.4 μ m, effectively preventing microbial adhesion and material corrosion. The storage tank has a capacity of ≥ 2 tons and is equipped with nitrogen protection or circulating disinfection system. The nitrogen protection system isolates air and inhibits microbial growth by continuously introducing high-purity nitrogen gas (purity ≥ 99.99%); The circulating disinfection system can regularly perform ozone or high-temperature circulating disinfection on the water tank to ensure stable quality of purified water during storage.
Terminal filteringInstall a 0.22 μ m microporous filter membrane to perform final filtration on the purified water treated as described above, intercepting small particles, impurities, bacteria, and microbial fragments that may remain in the water, ensuring that the final effluent particle content is less than 1ppt, meeting the purity standard and meeting the strict requirements of the medical industry for water quality.
