    Purified water equipment is used to meet the needs of various industries to produce purified water.
    It is mostly used in pharmaceuticals, medical devices, cosmetics, food, health care products and other industries.
    , European Pharmacopoeia standards, in line with GMP, FDA and other certification requirements
    .

    Understanding the functions of the main filtration components of purified water equipment can help us quickly grasp the process and process of purified water equipment
    .

    Figure 1 Jingderui purified water equipment 1.
    Multi-media filter Multi-media filters are mostly filled with filter materials such as quartz sand, anthracite and manganese sand
    .

    Its function is mainly to reduce the turbidity of water, and can remove a large number of bacteria, viruses, organic matter, etc.
    in the water
    .

    Thereby creating favorable conditions for the subsequent disinfection process
    .

    2.
    Softener filter The softener filter is mainly filled with sodium cation exchange resin
    .

    Through the ion exchange reaction of resin, the hardness of water is reduced, calcium and magnesium ions are prevented from combining with carbonate and sulfate ions, and the possibility of scaling of subsequent water treatment equipment or pipelines is effectively reduced
    .

    3.
    Activated carbon filter Activated carbon has a large number of micropores and a huge specific surface area, and has physical adsorption capacity
    .

    It can effectively absorb impurities in water, especially organic matter and microorganisms
    .

    The oxygen-containing catalytic oxidation and chemical adsorption functions formed on the surface of activated carbon can remove a part of the metal ions in the water
    .

    The activated carbon filter has an adsorption effect on the residual chlorine remaining in the water to protect the downstream stainless steel equipment and the surface of the pipeline and meet the water entry requirements of the subsequent water treatment unit
    .

    Fourth, security filter Security filter is also called precision filter, the filtration precision is generally 5μm
    .

    Its function is to intercept all substances with a particle size larger than 5 μm to meet the water entry requirements of reverse osmosis
    .

    5.
    The key to the application of reverse osmosis RO technology lies in the performance of the reverse osmosis membrane that plays the role of desalination
    .

    A reverse osmosis membrane is a semi-permeable membrane that only allows water molecules to pass through and does not allow solutes to pass through
    .

    In addition to applying the principles of reverse osmosis and reverse osmosis, reverse osmosis technology also utilizes the selective adsorption of membranes and the screening mechanism for organic matter
    .

    The pore size of the reverse osmosis membrane is mostly less than or equal to 10 × 10-10m, and the separation object is the organic matter in the solution with an ion range and a molecular weight of several hundreds
    .

    It can filter out various bacteria, such as Pseudomonas aeruginosa, one of the smallest bacteria (3000×10-10m), and various viruses, such as influenza virus (800×10-10m), meningitis virus (200× 10-10m), and can filter out pyrogen (10~500×10-10m)
    .

    6.
    Continuous Electrodeionization EDI.
    Abbreviated as continuous electrodeionization technology, through the selective permeation of cations and anions by cationic and anion membranes and the exchange of ions in water by ion exchange resins, the directional migration of ions in water is realized under the action of an electric field.
    In order to achieve the purpose of deep desalination of water, the conductivity of the produced water is less than or equal to 0.
    1μS/cm
    .

    At the same time, the EDI concentrated water is returned to the raw water tank for recycling, saving water
    .

    When the concentrated water flow is greater than 60L/h, the EDI power is turned on, and when the flow is less than 60L/h, the EDI power is turned off
    .

    When the conductivity of the EDI product water is less than or equal to 0.
    1μS/cm, it enters the purified water tank, and when the conductivity of the product water is greater than or equal to 0.
    1μS/cm, it enters the raw water tank for recycling
    .

    The above are the main filter components used in purified water equipment.
    You can choose a combination according to your water effluent requirements, or contact our company for consultation
