    Swimming is a fantastic way to keep fit and healthy not to mention it being a life saving skill we should all have. The fact that there are alternatives to swimming pool disinfection, offers you the chance to make swimming even more beneficial to health. Sodium and calcium hypochlorite are disinfectants used in bleach and bleach products, purifying drinking water, swimming pools, ponds and wastewater. Sodium and calcium hypochlorite also are used in soil treatment of fruits and vegetables. Hypochlorites control bacteria, fungi and slime-forming algae that causes disease in people and animals.

      Swimming Pool Disinfection Using UV Technology 1. MORE HEALTH, LESS CHEMICALS A solution by - 2. POOL CHEMICALS:THE PROBLEM • Most pools and spas depend on chemicals to sanitize them. • Chlorine has been in use for more than 40 years to create “safe pools”.   Chlorine comes in three main types, chlorine gas, sodium hypochlorite and calcium hypochlorite. In this article I will focus on sodium hypochlorite. Sodium hypochlorite has another name, you probably know it better as bleach. The active ingredient in commercial bleach is sodium hypochlorite. This is commonly available in 6%, 12% and 15% solutions.

    The comparison allowed to determine that the value of chloramines did not exceed the limit of mg Cl 2 /L [] and mg Cl 2 /L [20] due to the disinfection with sodium hypochlorite. The microbicidal potency of BBAS chlorinated with sodium hypochlorite (NaOC1) for 5 min to free chlorine concentractions of , and 1 mg/1 appeared to meet the tentative standard of 4 decimals reduction (D.R.) within 5 min against the bacterial test strains used, e.g. Staph, aureus, Str. faecalis, P. aeruginosa, E. coli and Prot. by: 5.

The generator output can be fed directly into the pool water as hypochloric acid or it can be temporarily stored (as sodium hypochlorite) in atank, after mixing with the generated caustic soda. Automatic Control. The chlorine-based disinfection, a free chlorine residual is typically maintaned.

Sodium hypochlorite generally makes up % of the volume; dissolved in water, it has a strongly alkaline pH, which can irritate the skin. The idea of strong acids causing burns is common knowledge, but in fact, strong alkalis can be just as dangerous, and concentrated bleach is at a high enough pH to cause burns to the skin on contact.

Sodium hypochlorite in swimming pools The concentration of sodium hypochlorite that is found in swimming pools is generally not harmful to people. When there is too much chlorine in the water, this burns the body tissues, which causes damage to air tracts. Disinfection methods for swimming pool water In some countries, sodium hypochlorite is used for both oxidation and disinfection of swimming pools.

When it is added to water, sodium hypochlorite increases the pH value. It is better to use chlorine as a disinfectant and an oxidizer at a pH value of 6,5. Often, acid is added to lower the pH value.

Sodium hypochlorite and calcium hypochlorite Systems using sodium or calcium hypochlorite are suitable for all types of pool. Free chlorine level To achieve the best possible water quality, it is recommended that the free chlorine residual should be at the lowest level File Size: 55KB.

swimming pool water chlorination & disinfection Chlorine swimming pools have a tendency to irritate skin and eyes by spending a period of time in a chlorine swimmingpool. Body itching and eyes will be bloodshot by using chlorine in swimming pools. Advanced disinfection. In accordance with DINchlorine gas, calcium hypochlorite and sodium hypochlorite (sodium-calcium hypochlorite) are approved for disinfection purposes.

The most commonly used solution is chlorine gas, but this brings with it a certain potential danger. Sodium hypochlorite, commonly known as bleach, is most frequently used as a disinfecting agent.

It is a broad-spectrum disinfectant that is effective for the disinfection of viruses, bacteria, fungi, and mycobacterium. However, sodium hypochlorite is NOT effective in the disinfection of bacterial spores and prions.

An estimated cost comparison between hypochlorite treatment and ozonation is shown below based on a 25 × 25 m commercial swimming pool which is operated days per year. The comparison includes the hypochlorite chemical costs for chlorination and the power consumption costs for an ozone generator coupled with an oxygen concentrator.

Due to the complexity of swimming pool water chemistry, human exposure and potential health risks are still poorly known to date.

Swimming pool water chemistry deals with the composition of the source water, the transformation of this water (e.g. disinfection processes) and the actions in the swimming pool (disinfection, swimmers, etc.).Cited by:.
