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.
