Specialty Products Organic
Organic contaminants in a pool or spa are things like bacteria, algae and bather waste, which are objectionable because they can affect the health of swimmers and bathers. Organic contaminants are controlled by such things as chlorine, bromine, ozone, ionizers, ultra violet sterilizers, algaecides and non-chlorine shock treatments chemicals.
Foggy water or turbid water can be cause by many factors and combinations of these factors. Some of the main factors that will cause foggy water in order of most likely are : Low water level, lower sanitizer levels, dirt filter, chemical added, pH to high, TDS level to high. The most important point to focus on is finding the problem causing the foggy water and try to correct it.
Using a coagulant will allow the small partials to be joined together so the filter can remove them faster
The active ingredient in these non-chlorine shock products is potassium peroxymonosulfate, also known as permonosulfate. Like chlorine, permonosulfate is an oxidizer that will destroy organic contaminants such as ammonia in spas. However, permonosulfate compounds do not kill or disinfect they simply control organics and combined chlorines, helping assure that the chlorine can do its job as a sanitizer. Permonosulfates oxidize by using the element after which oxidation got its name -- oxygen. Oxygen is a pure form of oxidizer.
Using a oxidizer will stop smell and help to keep the water clear.
When chlorine is added to the water, it combined with these ammonia and nitrogen compounds to form chloramines. These chloramines (also known as combined chlorine) smell bad, and they are eye and body irritants. Not only that, they also disable the free chlorine. Chloramines are still disinfectants, but they are 40 to 60 times less effective than free chlorine. And in a swimming pool or spa, we want a fast, effective kill. Therefore, we want the presence of a lot of free available chlorine. So we need to get rid of the combined chlorine. In pools that are sanitized with bromine, the odour problem does not exist, and combined bromine (bromamines) are as effective as free bromine for disinfection's. Nevertheless, it is still necessary to periodically oxidize the organic wastes to prevent them from building up and becoming sources of irritation.
The first step in dealing with the problem of combined chlorine is to test the water to see how much of the chlorine in the water is free and how much is combined. The commonly used OTO test will not perform this task -- it can only tell you the total chlorine level and can't differentiate between free and combined chlorine. However, a DPD test kit or a spa test strip will do the job.
