Why Using Chlorine Chemicals for Swimming Pool Water Disinfectant

To control quality of swimming pool water, a filtering system is usually not adequate. To control or prevent growth of organisms in swimming pool water non-professional users may treat private pools. For disinfection, appropriate balanced water chemistry is required to maintain an adequate active chlorine level. The active chlorine (free chlorine) disinfectant is used to sanitize, i.e. to kill disease-causing organisms, and to oxidize, i.e. to destroy ammonia, nitrogen-containing contaminants and swimmer waste. A stabilizer in outdoor pools influences the active chlorine level by reducing the chlorine dissipation and in this way, the chlorine level is stabilized i.e. consistent. Furthermore, the pH of the pool water should measure between 7.2 and 7.8 to maintain an ample active chlorine level. Additionally, total alkalinity (amount of alkaline substances) in the pool buffers the water against sudden changes in the pH.

Chlorine is extremely susceptible to sunlight and needs to be regularly monitored. But just as we use sunscreen to protect our skin from the sun, chlorine uses a sunscreen of Cyanuric acid. Used this way, Cyanuric acid is also commonly called a stabilizer or conditioner. Cyanuric acid is used in outdoor pools along with the inorganic chlorine for effective sanitations. The most popular chlorine based Cyanuric acid product called Tri-Chloro-Iso Cyanuric acid with 90% available Chlorine ( TCCA 90 ).

Know About The History of Chlorine

One of the first known uses of chlorine for disinfection was in the form of hypochlorite known as chloride of lime. Snow used it in 18503 after an outbreak of cholera to attempt to disinfect the Broad Street Pump water supply in London. Berthollet, in 1785, prepared a bleaching agent by dissolving ‘Scheele’s gas’ in water and in 1789 improved it by mixing it with a solution of caustic potash (KOH). This was carried out in a French chemical plant in Javel and is still know as Javelle water to this day. A short while later Labarraque replaced the expensive potassium hydroxide with caustic soda; this development resulted in what was probably the first use of sodium hypochlorite as bleach.

Chlorine first began to be used as a disinfectant in the late 1800s to early 1900s. Liquid bleach – sodium hypochlorite – came into widespread use in the 1930s and today it is the most widely used of all the chlorinated bleaches. Hypochlorite solutions were used for the treatment of open wounds during World War I and led to the use of on-site generation of hypochlorite in hospitals. These went out of favour until the 1990s, which saw a great surge in the interest of on-site generation of chlorine.

Chemistry of Trichloroisocyanuric Acid Chlorine Disinfectant

After hydrolysis in water, TCCA will be converted to hypochlorous acid (HOCL), which has strong microbial activity. The hydrolysis by-product, cyanuric acid, acts as a stabilizer and prevents conversion of hypochlorous acid into hypochlorite ion (OCL-) owing to sunshine and heat, which has low microbial activity.

Trichloroisocyanuric acid effervescent tablets are a highly effective, low-toxic, broad-spectrum, rapid disinfectant that has been widely promoted internationally. It can effectively kill a variety of bacteria, fungi, spores, mold, cholera. It has special effects on killing hepatitis A and hepatitis B virus, and also has a good disinfection effect on sexual viruses and HIV.
