Electrochemical Recirculating Water Treatment System for Cooling Tower

Electrochemical Recirculating Water Treatment System not only has the anti scaling, sterilization, algae killing, corrosion inhibition and other properties that can be achieved by chemical circulating water treatment, but also has functions such as scale removal, scale dissolution, and degradation of organic substances, thereby achieving the effects of increasing concentration ratio, reducing emissions, saving water and electricity in an environmentally friendly manner.

Electrochemical Recirculating Water Treatment System for Cooling Tower

 

 

 

Theoretical Basis

The theoretical basis of electrochemical recirculating water treatment equipment of Purevita is electrolysis theory and polarmolecular theory. Under the action of direct current, the positive and negativeions in the aqueous solution between the positive and negative plates will move to the polar opposite plate,resulting in electron gain and loss reaction (i.e.,discharge reaction).

 

After anti scaling, descaling and preventing new scale, old scale will become loose and soft scale, gradually falls off, and hard scale will be removed.

 

Sterilization and algae removal of organic matter in the water to inhibit the growth of bacteria and algae

 

Corrosion inhibition and corrosion prevention:

Fe2 +20H-=Fe(OH),is oxidized into Fe,0 -nH,0 (red rust),Fe,O -H,O reacts withelectrons to form Fe 0,(magnet), and Fe Owill separate the steel pipe wall from thewater.

Three Major Problems Recirculating Water

 

  • #
    Scaling
    Hard scale
    Calcium carbonate,calcium phosphate,calcium sulfate,magnesium hydroxide,magnesium silicate,etc.
    Soft scale
    Mud,dust,sand,corrosionproducts,microorganisms,bacteria,algaeandsecretions,general debris,etc.
  • #
    Corrosion
    Microbial corrosion
    Metal corrosion caused by microorganisms
    Corrosion of dissolved oxygen
    Depolarization of dissolved oxygen promotes the microcell reaction of metal surface
    Point corrosion
    Some spot-or hole-like local corrosion occurs on the surface of the metal
    More than 70% of corrosion is caused by accelerated microbial growth
  • #
    Bacteria and algae breeding
    Microbial growth
    The temperature, PH, COD, carbon source, nitrogen source and inorganic salt of cooling water meet the breeding conditions  of microorganisms
    Fungi anaerobes
    Bacteria legionella
    Algae

Acidic Electrolyzed Oxidizing Water Ionizer
Acidic Electrolyzed Oxidizing Water Ionizer For Hospital

Acidic Electrolyzed Oxidizing Water, another name “Hypochlorous acid” is a neutral, low-molecular-weight small molecule with no charge, allowing it to easily penetrate the negatively charged cell membranes and efficiently disrupt functional enzymes inside bacteria. Its bactericidal effectiveness is approximately 100 times greater than that of alcohol or iodine-based disinfectants. It can rapidly eliminate a wide range of microbial pathogens within a short period. Even highly resilient spore-forming bacteria can be killed within 10 minutes, achieving a destruction rate of over 99% against bacteria, fungi, and viruses.

The ultraviolet disinfector integrates comprehensive sciences such as optics, microbiology, mechanics, chemistry, electronics, and fluid mechanics. The UV-C ultraviolet light generated by the imported or high-quality domestically produced high-efficiency, high-intensity, and long-life UV-C ultraviolet light generating device is used to irradiate the flowing water. When the bacteria and viruses in the water are irradiated with a sufficient dose of UV-C ultraviolet light (wavelength 253.7nm), their cell DNA and cell structure are destroyed, and cell regeneration cannot proceed, thereby achieving the effect of water disinfection and purification. The ultraviolet light with a wavelength of 185nm can also decompose organic molecules in the water, produce hydroxyl free radicals, and oxidize organic molecules in the water into CO₂ and H₂O , and achieve the effect of removing TOC.
