How to clean the pool waterOctober 31, 2010
Sooner or later, they think about how to clean the water in the pool, every owner of a home mini pond, because even perfectly filtered water loses its transparency over time. There may be a lot of reasons for this, and in this article we will look at the most common cases of water pollution and methods of water purification in the pool for each of them. Construction of the pool is a rather serious engineering and construction task, and therefore it would be desirable that the efforts you spent to create it were not overshadowed by improper operation.
If the water in your pool has become turbid, you must first establish the cause, eliminate it, achieve the required water quality and then constantly maintain the corrected parameters, monitoring them from time to time.
Many companies are engaged in water purification in swimming pools, but their services cost a lot, moreover, they can often cope with pollution on their own. First of all, you need to use a test kit (for example, chlorine / pH) to check the parameters of water, and then follow on from what the test showed.
- Sometimes the water in the pool becomes milky. A possible reason for this is solid salts resulting from high pH or total alkalinity. In this case, it is necessary to lower the pH to the correct value using special chemicals.
- If the water is cloudy, then there may be several reasons. For example, dirt has accumulated due to insufficient filtration or weak chlorination. In the first case, you must thoroughly wash the filter or, if necessary, replace it. Sometimes the filter does not work due to the fact that the sand in it is contaminated or covered with calcium deposits (in the case of hard water). In this case, the sand must be washed with a special detergent solution or completely replaced. If the reason is insufficient chlorination, then superchlorination with unstable chlorine is carried out using calcium hypochlorite or sodium hypochlorite, in order to increase the level of free chlorine to 10 mg / l. Then a clarifier is added to make the water clear. The reason for the turbidity of the water can also be the use of stable chlorine such as dichloro and trichloride.In this case, the chlorination efficiency in the pool is reduced, since the level of free chlorine in the pool is minimal and, therefore, chlorine does not have time to destroy harmful bacteria.
The level of sustainable chlorine water is reduced by replacing part of the water and filling the pool with new water. This is followed by superchlorination in order to achieve a level of free chlorine of 10 mg / l.
- Sometimes the pool water turns green. It happens then. When chlorination is inefficient and algae breed in water. To eliminate this effect, superchlorination with unstable chlorine is also carried out (for faster action) or algicide is used, clearing the pool of all algae. It is also necessary to rinse the filter to remove dead algae from it. Then a clarifier is added to the water, and for prophylaxis, an algicide or chlorine is added from time to time with the addition of an algicide.
- Rust in the water indicates problems with pipes or fittings. The pipes may rust due to the low pH of the water, and ferrous metal or steel fittings are also subject to rust. In this case, the pool water should be replaced, after cleaning all rust stains from the pool surfaces and replacing ferrous metal fittings with copper or PVC.The parameters of the new water must be adjusted to prevent rusting.
