General arrangements for the evening run sediment pool, early in the morning using a manual suction machine sucked sediment. Can not be dragged to pull late, because the sun to the swimming pool, the sediment in the floats will float, affecting the water effect, so try to get up early in the morning smoke pollution. It is generally 5-7 days to use a pool sediment, or pool sediment if the pool water is cloudy. The dosage of 1000 cubic water put 5-10kg. In the sediment pool before launching the first water to adjust the PH to 7.5 or so. Because high pH helps to eliminate the polar molecules in water, so that the suspended particles in water is easy to settle. The most suitable pH value of the swimming pool precipitating agent (polyaluminum chloride) usually used is 7.5 ~ 8.5. In alkaline environment, it can give full play to its hydroxyl bridging role to accelerate the settlement and sedimentation. Polyaluminum chloride when used first dissolved in water: Bucket Sheng 10 times more water, and then slowly add polyaluminum chloride, while stirring while adding, polyaluminum chloride quickly dissolved in water. Can not add water after the polymerization of aluminum chloride, because this aluminum chloride will caking, it is difficult to disperse and dissolve. Polyaluminum chloride will dissolve heat, the higher the heat to prove the better quality. Dissolved PAC should be added to the swimming pool as soon as possible. Some swimming pools are added slowly by dosing pump, some directly at the nozzle, plus the direct effect is better than the pump, but the direct increase of the workload of sewage will be larger. The minimum time required for settling of the flocculant is 6 hours, which usually takes 6-8 hours to completely precipitate. If the swimming pool water deeper need more time, in the water surface, the settling agent settling slower. Therefore, the deep-water swimming pool in addition to adding precipitant, but also give more settling time. The company is located in:
