Working Principle
Sea Water Electrolysis Sodium Hypochlorite Generator for Cooling Tower is generating sodium hypochlorite through the electrolysis of seawater is a cost-effective and safe method to eliminate algae and microorganisms and prevent the biofouling. Sodium hypochlorite is a versatile oxidizing agent that can be generated and used on-site.
• Basic reactions occurring in the electrolytic cell:
At the anode, chlorine gas is evolved:
2Cl- = Cl2 + 2e- _________________ ①
At the cathode, hydrogen gas is evolved:
2H+ + 2e- = H2 __________________ ②
The Cl2 evolved at the anode dissolves in the electrolyte to form HCl and HOCl. Since there is no membrane between the anode and the cathode, the H2 evolved at the cathode and generates OH-, which combines with the H+ produced by dissociation to form H2O and NaOCl, thus completing the homogeneous secondary chemical reaction. The overall reaction is:
NaCl + H2O → NaOCl + H2
Industrial Biofouling Control
Purevita seawater electrochlorination systems are a reliable and economic solution for industrial biofouling control. The electrochlorination process is simple and straight forward, combining three common consumables (salt(sea water), water and electricity) to generate a disinfecting agent. SANILEC systems can be provided in any capacity to meet customer and application-specific needs.
On-site generation of sodium hypochlorite is an economical and safe method to produce a powerful biocide and disinfecting agent for use in industrial applications. When injected into the cooling water circuits of electric power stations or industrial plants, on-site generated sodium hypochlorite provides efficient protection to the equipment against the growth of micro and macro organic fouling. This occurs without the undesirable side effects of commercial hypochlorite, such as the build-up of hard deposits by reaction of excess alkalinity with the substances dissolved in water or the safety hazard connected with the transportation, storage and handling of chlorine gas. The technology eliminates dependency on outside suppliers and the heavy costs of purchased commercial products.

Application
-
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.

Platinum-coated titanium electrode is a typical Dimensionally Stable Anode. It is a composite electrode constructed with a metallic titanium substrate as the base, upon which a thin layer of platinum (often not pure platinum but rather an alloy or mixture of platinum and other precious metals) serving as the active catalytic layer is applied onto its surface through specialized processes such as thermal decomposition or electroplating.

The alkaline electrolytic ionized water is formed by membrane electrolytic technology, and increases the concentration of hydroxide ions (OH-) (pH 10~12) and oxidation potential (-900 mV) in water. Unlike usual alkaline water, alkaline electrolytic ionized water does not contain synthetic surfactants or chemicals, so it is reliable and safe to use and has a high cleaning, sterilization and deodorization effect.
