How to purify swimming pool water

One: add flocculant precipitation suction treatment: stop the cycle of filtration equipment, according to a certain proportion of the dosage of flocculant to the pool water, so that fine suspended particles in the flocculant under the action of the formation of alum flowers, the use of its specific gravity greater than that of the water and in the state of static pool water naturally precipitate at the bottom of the pool to form a solid layer of precipitation after the use of other auxiliary equipment, such as underwater suction machine carefully suction off the layer of sedimentation after the visible transparent Pool water.

Method comment: this method is a traditional treatment, low cost, applicable to all swimming pools. Operation of the pool water chemical conditions to be very good control and cooperation, it is recommended by the top operating experience of the water quality management operation. Suction of the sediment layer, easy to cause secondary precipitation (should be said to be multiple precipitation, that is, today the sediment layer will be sucked out of the clean, but the next night after the past will often form some sediment in the bottom of the pool). Labor-intensive, sediment layer of suction can not use automatic suction machine (water turtle), if the use of the system piping configuration of the pool wall suction port suction, circulating water treatment filter valve group to be set to the direct discharge state (i.e., suction in addition to the dirty water is not discharged directly through the filter), the treatment process will be more wastewater. Most of the flocculants used are aluminum salt formulations, and aluminum salts are more harmful to the human body. The flocculation and sedimentation process must stop the opening of the pool. The pool must be closed for the flocculation and sedimentation process. The whole process takes about 12-15 hours.

Second: add clarifier junction contact filtration processing normal operation of the circulating filtration equipment, in the pool back to the mouth of the water near a certain proportion of the dosage of clarifying agent flocculant in the water, clarifying agent in the filter media for contact filtration, after 2-3 cycles, can effectively improve the pool water is not clear or even turbid feeling.

Review of the method: this method is the introduction of foreign pharmaceuticals in the past two years to promote the emerging treatment methods, applicable to swimming pools with circular filtration equipment, easy to use and simple, but the corresponding cost is higher (depending on the price of clarifiers). Treatment process pool can be open as usual, and does not cause sedimentation, without the need to do the complicated work of suction, and because there is no need for direct suction without the loss of waste pool water (this saving can be offset by the price of more expensive agents). With routine maintenance, it is easy to reach a visibility of more than 25 meters under the pool water. It is particularly effective in the case of cloudy and milky pool water. If you use the clarifying agent made of biological extracts from the seabed, it is even safer and non-toxic, and will not harm swimmers or cause accumulated aging of the pool water.
