Product Details
Process and scheme design of 2-ton laboratory testing water equipment
In professional fields such as laboratory testing, medical device cleaning, and pharmaceutical inspection, the quality of inspection water directly affects the accuracy of test results, the reliability of product quality, and the effectiveness of experimental data.Shangqiu 2-ton laboratory inspection water equipmentSpecially designed to meet these demanding requirements, with advanced water treatment technology as the core, and strictly following domestic and international standards such as the Chinese Pharmacopoeia, USP (United States Pharmacopeia), ISO, etc., a high-purity water treatment system has been constructed. The following provides a detailed introduction from the aspects of core water quality requirements, process flow, equipment configuration, etc., to provide comprehensive water solutions for related fields.
1、 Core water quality requirements: Strict standards to ensure professional needs
The quality standards for laboratory testing water are extremely strict, and all indicators must meet specific requirements to ensure its applicability and reliability in different application scenarios.
Purity indexAt 25 ℃, the conductivity should be ≤ 2 μ S/cm, which is a key parameter for measuring the content of ion impurities in water. Low conductivity means that the ion concentration in water is extremely low, which can effectively avoid the interference of ions on precision instrument analysis and experimental results.
Microorganisms and Heat Source ControlThe microbial limit requirement is<10 CFU/100 mL, and it must meet the standards of sterility and no heat source. In biological experiments, pharmaceutical testing, and other scenarios, the presence of microorganisms and heat sources may lead to serious consequences such as experimental data deviation and drug quality non-compliance. The requirement for endotoxin content is less than 0.25 EU/mL (when used for biological experiments or injection related tests). As a component of Gram negative bacterial cell walls, endotoxins may cause fever reactions in the body when present in trace amounts, which has a significant impact on experiments and drug safety.
Particulate matter and organic matterTo avoid interfering with the detection results, the content of particulate matter and organic matter in the water should approach zero. In experiments that require precision, such as HPLC and spectrometers, even small amounts of particulate matter and organic matter can lead to detection errors and affect the accuracy of experimental results.
These strict water quality requirements enable the 2-ton laboratory testing water equipment in Henan to be widely used in multiple fields, including laboratory reagent preparation. To ensure the accuracy and reproducibility of experimental results, the preparation of experimental reagents requires water quality, and high-purity testing water can avoid contamination of reagents by impurities; Instrument analysis, precision instruments such as HPLC and spectrometers are extremely sensitive to ions, organic matter, and particulate matter in water. High quality inspection water can ensure the normal operation of instruments and the reliability of detection results; Cleaning and disinfecting medical devices, the water used for cleaning and disinfecting medical devices is directly related to the health and safety of patients. Sterile and heat free testing water can effectively prevent contamination of medical devices during the cleaning process; Pharmaceutical raw material inspection and drug stability testing. In the pharmaceutical industry, inspection water is used for raw material inspection and drug stability testing, and its quality directly affects the quality and safety of drugs; Electronic industry components cleaning, etc. Electronic industry components also have strict water quality requirements. High purity inspection water can avoid performance degradation caused by water quality problems during the cleaning process.
2、 Typical process flow: Multi stage purification to ensure water quality meets standards
The 2-ton laboratory inspection water equipment in Henan Province adopts a multi-stage purification+aseptic control technology of "pretreatment system deep purification post-treatment and disinfection automation control". Each link closely cooperates to gradually improve water quality and ensure that the final produced water meets strict quality standards.
（1） Pre treatment system: the basic link of raw water purification
The main function of the pretreatment system is to remove suspended solids, colloids, sediment, 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 deep purification, and protect the core equipment to extend its service life.
Multi media filterThe interior adopts a layered filling structure, with the upper layer filled with quartz sand with a particle size of 0.5-1.2mm. With its small particle gaps, it can effectively intercept tiny particles; Fill the lower layer with smokeless coal with a particle size of 1-2mm to remove larger impurities. When the raw water flows through the filter layer from top to bottom, relying on the interception, precipitation, and adsorption of the filter material, large particles such as suspended solids and colloids with a particle size of 5-10 μ m in the water can be removed, significantly reducing the turbidity of the raw water and making the effluent clearer.
Activated carbon filterHigh quality coconut shell activated carbon is selected, which has a rich microporous structure and a specific surface area of up to 1000-1500m ²/g, endowing it with excellent adsorption performance. On the one hand, activated carbon converts highly oxidizing residual chlorine in raw water into harmless chloride ions through catalytic reduction, avoiding oxidative damage to subsequent reverse osmosis membranes caused by residual chlorine; 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, improve water quality, and reduce 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 calcium and magnesium ion concentration>100ppm), a softener needs to be configured. The softener is filled with strong acidic cation 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 reverse osmosis membrane, and ensuring the stable operation and efficient desalination performance of the reverse osmosis system.
（2） Deep purification: a key step towards achieving high purity
Double stage reverse osmosis (RO)Reverse osmosis is the core technology for achieving deep desalination of raw water, and the two-stage RO design further enhances desalination efficiency and water purity. The first level RO uses RO membrane elements with excellent anti pollution performance, such as Dow BW30-400IG DRY membrane, with a desalination rate of ≥ 98%. Under the pressure of 1.0-1.5MPa provided by the high-pressure pump, the raw water passes through the RO membrane, and water molecules selectively permeate through the membrane, while impurities such as salt, organic matter, and microorganisms are intercepted, resulting in a conductivity of 1-10 μ S/cm for the first stage RO produced water. The secondary RO performs secondary desalination on the water produced by the primary RO, further removing residual trace salts and impurities, providing high-quality influent for subsequent EDI processing.
EDI (Electrodeionization)The EDI module achieves continuous deep desalination through the synergistic effect of electrodialysis and ion exchange resin. Under the action of a direct current electric field, the ion exchange resin inside the module adsorbs cations and anions in water. At the same time, the selective permeability of the ion exchange membrane causes ions to migrate in a directional manner from the fresh water chamber to the concentrated water chamber, thereby achieving deep desalination. This process does not require acid-base chemical regeneration. The resin is continuously regenerated through hydrogen ions (H ⁺) and hydroxide ions (OH ⁻) generated by water electrolysis, which not only reduces operating costs and environmental pollution, but also stably produces high-purity water with conductivity reduced to below 0.056 μ S/cm, completing the polishing treatment of water quality.
（3） Post treatment and disinfection: the final barrier to ensure water quality safety
Ultraviolet sterilization (UV)Using 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 structure of residual microorganisms, causing them to lose their ability to reproduce and survive, with a sterilization rate of over 99.9%. It effectively kills bacteria, viruses, and other microorganisms remaining in water, ensuring that the effluent meets sterile standards.
Micro porous filtration (0.22 μ m)Install a microporous membrane with a pore size of 0.22 μ m to perform final filtration on water that has been sterilized by ultraviolet radiation, intercepting small particles and bacteria to prevent them from entering the terminal storage stage and further ensuring the purity of water quality.
Terminal storage and recyclingUsing 316L stainless steel storage tanks as terminal storage equipment, this material has good corrosion resistance and hygiene performance, which can effectively prevent the tanks from polluting water quality. The storage tank is equipped with a circulating insulation system, which suppresses microbial growth by maintaining a certain water temperature (usually within a suitable temperature range); At the same time, optional ozone or pasteurization devices can be used to regularly disinfect the water in the storage tank, ensuring stable water quality during storage and meeting long-term usage needs.
（4） Automated control: intelligent management improves operational efficiency
The equipment adopts PLC system for automatic control, real-time monitoring of conductivity pH、 Key parameters such as temperature and flow rate. Once an abnormal parameter occurs, the system immediately triggers a fault alarm mechanism and automatically records relevant data, making it convenient for operators to troubleshoot the problem in a timely manner. In addition, the system supports GMP compliance requirements and can comprehensively monitor and manage the operation process of equipment to ensure compliance with relevant standards and specifications. It also facilitates data traceability and analysis, providing strong support for quality management in laboratories and enterprises.
3、 Equipment configuration and selection: High quality configuration ensures reliable performance
（1） Core components
Preprocessing unitComposed of a multi-media filter, activated carbon filter, and softener (configured according to the hardness of the raw water), these devices work together to achieve initial purification and protection of the raw water, creating favorable conditions for subsequent deep treatment.
hostThe combination of two-stage RO and EDI modules is the core part of the equipment to achieve stable output of 2 tons/hour of high-purity water. The dual stage RO ensures efficient desalination, and the EDI module further enhances water quality purity. The combination of the two can stably produce inspection water that meets strict water quality requirements.
post-processingIncluding UV sterilizers, microporous membranes, sterile storage tanks, and other equipment, the safety and stability of effluent water quality are ensured through sterilization, filtration, and storage processes.
（2） Material requirements
The components of the equipment that come into contact with water are made of 316L stainless steel or PVDF material. 316L stainless steel has excellent corrosion resistance and good hygiene performance, which can effectively prevent material corrosion and secondary pollution; PVDF material has the characteristics of high strength, chemical corrosion resistance, and pollution resistance, which can ensure that harmful substances are not released during long-term use and ensure that water quality is not affected. The storage tank is equipped with a respirator and filled with high-efficiency filtering materials to filter out microorganisms and particulate impurities in the air, preventing external pollution from entering the storage tank; Equipped with electric heating function, it maintains the water temperature within a suitable range, inhibits bacterial growth, and ensures stable water quality during storage.
