Electrochemical Recirculating Water Treatment System for Cooling Tower

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.

Hypochlorous acid generator is a system which is produced by electrolysis of tap water through water purification system and is produced by a special electrolytic cell. The system produce hypochlorous acid (HCLO) with pH (5~6.5), redox potential (ORP value +750mv or more) and available chlorine (50~60mg/L), also produce sodium hydroxide (NaOH) with PH (10~12), redox potential(ORP value -800~900 mv).

The electrolyzer is fed a DC current from the rectifier and electrolyzes the diluted brine into sodium hypochlorite solution. Chlorine evolves at the anode surface, while hydrogen and hydroxide evolves at the cathode surface. The secondary reaction of chlorine, sodium and the hydroxyl ion nets sodium hypochlorite (chlorine bleach) at a 0.8% solution. Below 1%, hypo is classified as a non-hazardous chemical although still a very effective disinfectant. The only by-product, hydrogen, is safely vented into the atmosphere.

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.

The ozone generation chamber and power cabinet are designed as separate units, allowing flexible placement and easy installation. Suitable for large-scale ozone generators.  

The Purevita sodium hypochlorite generator generates a 0.8 % sodium hypochlorite solution through the electrolysis of brine, consuming only water, salt and electricity. By producing hypochlorite on-site and on-demand, the system eliminates concerns associated with transportation and storage of chlorine gas or commercial sodium hypochlorite solutions, making it ideal for any medium to large scale application requiring chlorination.

The polarity reverse titanium electrolytic cell is utilized in sodium hypochlorite generators. Sodium hypochlorite solution is produced by electrolyzing a sodium chloride solution without a membrane and then diluting it. This technology is suitable for various applications including sodium hypochlorite generators, water treatment equipment, and electrolytic disinfection equipment.

Purevita UV Sterilization Technology utilizes a specially designed high-intensity, high-efficiency, and long-life C-band 253.6nm ultraviolet light generator to produce powerful UV irradiation for water streams. This UV light destroys the DNA structure of pathogens in water, rendering them inactive and achieving sterilization. The principle of UV sterilization relies on photon energy: shorter wavelengths correspond to higher photon energy, resulting in stronger germicidal efficacy. At 253.6nm, UV light rapidly and efficiently disrupts bacterial DNA, preventing replication and ensuring effective water disinfection.
