Those chemicals about the swimming pool (1)

Your pool’s filtration system plays a major role in keeping your water clean, but you also have to rely on chemistry to fine-tune your water. Careful handling of pool chemistry balance is important for the following reasons:

• Harmful pathogens (such as bacteria) can grow in the water. If the pool water is untreated, germ-carrying microbes can easily spread from person to person.

• If the pool’s chemistry is out of balance, it can damage various parts of the pool.

• Chemically unbalanced water can irritate human skin and eyes.

• Water that is chemically out of balance can become cloudy.

To treat pathogens in water, a Disinfectant must be administered to eliminate the germs. The most common pool sanitizers are compounds that contain elemental chlorine, such as calcium hypochlorite (solid) or sodium hypochlorite (liquid). When chlorine-containing compounds are put into water, chlorine will chemically react with water to form various chemical substances, the most important being hypochlorous acid. Hypochlorous acid kills bacteria and other pathogens by attacking lipids in cell walls, destroying enzymes and structures within cells through an oxidation reaction. Alternative sanitizers, such as bromide, work essentially the same way, but have slightly different germicidal effects.

Usually you can use chlorine in granules, powder or flakes and drop it into the water at either point. Pool experts generally recommend dosing chlorine with a chemical feeder immediately after the filter treatment. If chlorine is dosed directly into the pool (such as using flake chlorine in a skimmer tank), the chlorine concentration in these areas may be too high.

One big problem with hypochlorous acid: it’s not particularly stable. Hypochlorous acid degrades when exposed to the sun’s ultraviolet rays. Additionally, hypochlorous acid may combine with other chemicals to form new compounds. Stabilizers (such as Cyanuric Acid) are often found in pool chlorinators. Stabilizers chemically react with chlorine to form more stable compounds. The new compound is also less prone to degradation when exposed to ultraviolet light.

Even with stabilizers, hypochlorous acid may combine with other chemicals and the resulting compound is not effective at disinfecting bacteria. For example, hypochlorous acid may combine with chemicals such as ammonia in urine to produce various chloramines. Chloramines are not only poor disinfectants, but they can actually irritate the skin and eyes, and give off a bad smell. The peculiar smell and eye allergies in swimming pools are actually caused by chloramines, not ordinary hypochlorous acid. Strong odors usually indicate too little free chlorine (hypochlorous acid), not too much. To get rid of chloramines, pool managers must shock the pool: Dosing the chemical beyond normal levels to remove organic matter and unwanted compounds.

The above is the introduction of swimming pool disinfectant and Chlorine Stabilizer. There are many more about swimming pool chemicals, continue to pay attention to me to keep abreast of the information you need.
