Chlorine Dioxide Generator by Electrolytic Saturated NaCl Solution for Cooling Tower

Introduction

Chlorine dioxide, ClO2, is one of the most effective bleaching agents for use in industrial and domestic process and services, and for commercial and consumer products. The strong oxidative potential of the molecule makes it ideal for a wide variety of uses that include disinfecting, sterilizing, and bleaching. Concentrations of chlorine dioxide in an aqueous solution as low as 1 part per million (ppm) or less, are known to kill a wide variety of microorganisms, including bacteria, viruses, molds, fungi, and spores. Higher concentrations of chlorine dioxide, up to several hundred ppm, provide even higher disinfection, bleaching and oxidation of numerous compounds for a variety of applications, including the paper and pulp industry, waste water treatment, industrial water treatment (e.g. cooling water), fruit-vegetable disinfection, oil industry treatment of sulfites, textile industry, and medical waste treatment

Performance feature

1. Electrode is combined with rare metals such as Ru, Ir, Pt etc. high electrolysis performance and long service life

2. Perfluorinated electrolytic membrane, which has low resistivity, corrosion resistance, cleaning free and long using life.

3. Forced cycling electrolytic liquid.

4. Ti heating conversion system, better heat dispersion.

5. Frame material: PVC, integrated design, small equipment footprint, simple installation, easy to use and maintain

6. Solid NaCl directly dosing system, safe and convenient.

7. The system can adjust the chlorine output automatically according to the signal of the residual chlorine meter. It can also adjust the chlorine output automatically according to the water flow by the flow meter.

Benefits of using chlorine dioxide

The advantages of using chlorine dioxide over sodium hypochlorite in water treatment, especially for drinking purpose, can be summarized in the following points:

Higher oxidizing power, which also results in a lower amount of chemical dosed, as well as in a broad-spectrum activity against bacteria, viruses, spores, algae, etc.

High broad-spectrum germicidal action over a wide pH range.

Effective biocide action against many chlorine resistant species, often found in distribution networks (iron and Sulphur bacteria, algae).

Germicidal action carried out in roughly half the time compared to chlorine, with a consequent reduction in any contact tanks space and costs.

Greater times of permanence in the network, then possibility of "coverage" of a distribution network having a wide extension and lack of necessity of ri-clonation, even starting from low concentrations of dosed chlorine dioxide.

Minimal formation of chlorinated compounds, able to alter the organoleptic properties of treated waters resulting in the formation of unpleasant odors and flavors, typical in water treatment with chlorine.

Excellent deodorizing properties in the pretreatment stage thanks to the oxidation of organic compounds with very low perceptibility threshold (phenolic derivatives, smells of earth, moss, rotten, etc.).

No reactions with ammonium ion which may be present in the water and therefore maintenance of germicidal ability.

No reactions with bromide ion (unlike ozone) and, therefore, absence of brominated organic compounds.

High solubility in water, even at relatively high temperatures, with consequent high efficiency using.
