The demand for chlorine is a problem of pool water chemistry that is more and more attention because of the changing climate, water chemistry and consumer understanding of the problem. There is also a serious problem in many public and private pools.
Chlorine demand is defined as "the amount of chlorine is reduced or converted to inert or less active forms of chlorine by substances in the water." Faust and Aly chemical water treatment is to say, "because chlorine is aNon-selective oxidant, almost all substances, water ... resolved to react and consume chlorine "In other words, the more" stuff "in the pool, its organic or inorganic, chemical .., vegetable or mineral, heavy, constant rain can cause a chlorine demand, or simply not in the able to successfully maintain a chlorine residual after treatment chock. Some household cleaners, which adds specially formulated for in-pool-water-use components such asPhosphates and nitrates is with the pool chlorine disinfectant causes a troubling question.
It could be another cause for the suspect, at least in the way we think about the chloramines. As you recall, Chloramines are chlorine molecules that are chemically up (we call them dirty) with organic waste such as ammonia which are connected, etc. More and more local authorities for water disinfection treatment with chloramines in the water supply drinking in those days. Chloramines arevery effective in killing pathogens in drinking water. However, chloramines are not effective oxidizing agents. You probably have a regular pink in the sink at home, shower and toilet noticed, especially in the last 4-5 years. These spots need more frequent cleaning. This is the same pink slime that is in your pool! Chloramines are used because they are very effective and less "offensive" to those who want to rid the planet of chlorine. This premise is absolute nonsensebecause you can not ban or get rid of an object! No matter how you did your pool with a garden hose, you are more chloramines in your pool at any time and aggravating already serious problem. Please note that this problem is not appropriate for people with well water (you have your problems).
A sure sign that the choice of a chlorine demand is the inability to provide a level of free chlorine of about 1.0 to 3.0 ppm available more than a couple of hours to keep, even aftershock or super chlorination.
Since 1992, one of the first pool area Technical Services Department has a huge amount of data collected at the request of chlorine. It seems that the situation is more common every year. Here are some actions (short version), that in dealing with chlorine-demand can help.
Make a real test of demand for chlorine. Your local pool should have a chlorine demand test station. In determining the real demand for chlorine, isimperative that the solution, and corrective action will be more accurate. Compare it to jump over the Grand Canyon, if you miss, you miss! If it takes 20 pounds of shock, to break the demand for chlorine, with £ 19 the problem will worsen, 20 pounds or more shock is to treat the topic. Maintenance of a disinfectant to the pool each day. Make sure that the correct number of tablets or chlorine sticks dissolve in the pool have. Check how many times a dayseen by visual examination of the eroding chlorine (both in the skimmer or in a chlorine plant) with a "normal". Normal refers to what you have 'normal' experienced in the past. Cold, slow erosion / dissolution rate; warmer water, faster erosion / dissolution rate. The pool should be shocked every week. PERIOD. Shocking oxidizes most of the "stuff" that was mentioned earlier. If you use a solar blanket, remove it! After each chemical, chemistryMust have time to answer, GAS-OFF, in order to get the right results. Maintaining the right balance of water. pH 7.2-7.6, total alkalinity 100 to 150 ppm, Calcium hardness 200-300 ppm. Good water balance promotes good, effective chlorine (disinfectant) performance.
Although a single cause for the demand for chlorine has not been determined (there are many), we found a common thread in many of these cases. A common thread, if a pool is always closed during the spring (not coveredDisinfectant). The heavy rains that ammonia is present leads to a demand for chlorine. Not covered by the house or compound fertilizers, which can be oxidized by chlorine, will result in a chlorine demand.
Finally, we have high demand our attention chlorine. Only careful monitoring and prompt treatment can be successful for a clear swimming pool. Visit your local pool REGULARLY (4 times per season). If you do not have a chlorine demand test, find someone who does.
