Titanium MMO Electrode Anode Used For Swimming Pool Sterilization & Disinfection

Salt Water Swimming Pool Hypochlorite Generator Anode Cell used Titanium anodes.

From the types of swimming pool water disinfection, there are chlorine, sodium hypochlorite, bleaching powder,chlorinedioxide,trichloroisocyanuric acid, hydrogen peroxide, ozone and other agents and methods, in addition to iodine, high-value oxidized water, ultraviolet disinfection and other means.

Compared with other disinfectants,Sodium Hypochlorite solution has obvious advantages: it is clear and transparent, and mutually soluble in water, which completely solves the difficulty of accurately dissolving in water such as chlorine, chlorine dioxide, ozone and other gas disinfectants, which is difficult to accurately add.

Technical difficulties, eliminating the potential safety hazards of running, leaking, leaking, poisoning, etc. that are often encountered with pharmaceuticals such as liquid chlorine, chlorine dioxide, ozone, etc., no side-reactants harmful to health and the environment are produced during disinfection, and no bleaching powder is brought during use. Of many precipitates.

Because of these characteristics, sodium hypochlorite has been widely used for disinfection and epidemic elimination of various water bodies including tap water, reclaimed water, industrial circulating water, swimming pool water, hospital sewage and other water bodies. However, because sodium hypochlorite solution is not easy to be stored for long periods of time, and transportation is inconvenient, sodium hypochlorite is mostly prepared and used on-site in the form of electrolytic brine.

The reaction principle of preparing sodium hypochlorite at the electrode is electrolysis of sodium chloride dissolved in water.

During electrolysis, sodium hypochlorite is formed. The most suitable salt concentration is 3-5 g / l. To increase salt utilization, use diaphragms, which are commonly used in large equipment and swimming pools.

The titanium anodes used in swimming pool disinfection mainly include the following products:

1. Ruthenium metal oxide coated titanium anode

2. Iridium platinum oxide coated titanium anode.

After many years of research, SAGA Anode developed a long – lived anode – metal coating – titanium anode for water treatment, water treatment, such as water amusement park, swimming pool and swimming pool.Anode for swimming pool chlorinator is a noble metal oxide with high electrocatalytic activity, strong oxidation resistance and good conductivity, which is insoluble anode.

The characteristics of the anode for swimming pool chlorinator are:

1.Titanium has the characteristics of light weight, good strength, good corrosion resistance and good performance. Especially, the property of moisture resisting chlorine is unmatched by other metal materials. For example, when there is a small amount of chloride ion in the electrolysis of water, the stainless steel plate will soon cause pitting corrosion, which will shorten the electrode life, and titanium will not have these problems.

2.because of adding a variety of platinum noble metals in the coating, the utility model has the advantages of high current efficiency, good conductivity, good electrocatalytic performance, strong oxidation resistance, long service life and energy saving.

3.Excellent reverse polarity.

MMO Titanium Electrode used for Swimming Pool Sterilization and disinfection

Every year millions of people all over the world enjoy themselves in swimming pools.The traditional method is to produce hypochlorous acid using containing chlorine chemicals to sterilization and disinfection acid production-electrolytic salt water to produce chlorine technology are widely used.

This method is that the electric current pass throuhg anelectrolytic cell containing sodium chloride(NaCl)solution, the anode produces chlorine(Cl)ions and the cathode produces hydroxide(OH+)ions,Like traditional chlorinated products, This method can also generate chlorine gas. The final product includes chloride ions,hydrogen ions,hypochlorous acid and so on.

Our DSA titanium anode and cathode can be used in such disinfection device. Improving efficiency of chlorine production is the greatest advantage that MMO coated titanium anode have. And, titanium anode and cathode could working with longer life as its excellent and stable performance. Without any doubt, great cohesion between coating and substrate is an another important factor for working life.

Increasing current density is available, which can boost production efficiency.

It can be worked in stronger corrosive medium or other special medium because of its better anti-corrosion property.

Short circuit is easily happened if lead anode is out of shape during working. However, titanium anode can avoid this problem and increase current efficiency.

Light weight can easily to be installed.

Different shape is available with high accuracy.

Ruthenium Iridium Coating insoluble titanium anode could used as a chlorine disinfection device for water electrolysis in swimming pool.

The greatest advantage of MMO is that it can greatly improve the efficiency of chlorine production, With excellent stability, Coating and base material combination is firmly, Long life timle.

Disinfection system using this chloride system can effectively reduce the corrosion rate of the swimming pool equipment and on the swimsuit bleaching injury, but also because of the use of soft water, but also can greatly reduce the stimulation to the skin.

Baoji YJ Titanium Ruthenium iridium titanium coating insoluble titanium anode, can be used as water amusement park / swimming pool electrolysis chlorine disinfection device. In the disinfection process, especially in the electrolysis of water, there are a variety of strong oxidizing substances in the water, and the anode is often reversed, so it must use a special functional titanium anode.

How to choose anode for swimming pool chlorinator ? Should be selected in accordance with the nature of the work, in the field of water treatment, anode for swimming pool chlorinator must have the following basic requirements:

  • 1. has good conductivity.
  • 2. strong corrosion resistance.
  • 3. mechanical strength and good processability.
  • 4.long working life.
  • 5.good electrocatalytic performance, etc.

MMO Anode Manufacturing Process

The typical manufacturing process for MMO anodes starts with surface preparation of the substrate by thoroughly cleaning the commercially pure titanium. This is followed by a chemical etching and in some cases mechanical abrasion of the surface. Once the substrate surface preparation is complete, the coating is applied as a mixture of metal salts and then thermally decomposed at temperatures ranging 400 to 600 °C. This forms an adherent layer of mixed metal oxides.

The MMO coatings can be applied in many layers and heat treated after each coat to achieve the desired coating loading to meet the current capacity requirements for the application.

Saga Anode provides metal oxide and metal mixture oxide coated (MMO coated) titanium anode such as RuO2/IrO2 coated anode, platinised anode. These anodes are used for cathode protection. 
RuO2, IrO2 coated anodes are used in chlor-alkali process, sodium hypochlorite production, sewage treatment and sea water desalinization, etc..
IrO2, Ta2O5 coated anode can be used in electrolytic copper foil, Al foil, organic electrolyte production and catholic protection.
Pt coated anodes are used in electrolytic deposition and water treatment, etc.. This is called Platinized Titanium Anode.
PbO2 coated Titanium electrodes are widely used in perchlorate production and sewage treatment, etc..

Titanium anode is also called DSA (dimensional stable anode) anode or insoluble Ti anode due to its good dimension stability and high corrosion resistance, which can prevent it from polluting the electrolysis solution and increase final product purity.

Electrowinning Anodes

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The resulting metals are said to be electrowon. Read more
