North and South water quality and water purificion installio
side soil support people, China large, water and soil differences larger northern South. As a living in the north for more than 10 years of southerners, appreciate the differences north and south, the climate and soil and water, and geographical differences also had the diet, customs, different temperament.
water quality differences between north and south, generally speaking, tend to be hard water north, south water softer. Soft water or hard, depending on the source of water. In general, rainfall or snowfall areas, water quality soft. The low rainfall, evaporation of the region, water too hard. This is because water vapor is condensed rain, the evaporation process to remove dissolved minerals, this principle can also be applied to desalination, distillation desalination process is used. So plenty of rain in the south, water soft. The little rainfall in northern regions, flows through the surface dissolved minerals, and accompanied by evaporation, increased salinity. But fundamentally, the decision is the source of water, simply use North and South to determine the water quality is unscientific. For example, Harbin ice and snow to melt to water quality in the north is soft; the mountains south of Guiyang, groundwater is more rigid. Also, according to our testing water quality, turbidity, COD, metals and fluorine content, and several other indicators, comprehensive evaluation, the northern citys water these indicators is higher south.
Thus in general, the north of the city water quality, water quality north, suitable water machine. This feedback from the customer pre-sales advice and after-sales problems can directly reflect a considerable number of customers concerned about whether part of the North can remove scale, heavy metals. Customer south of the small scale of the degree of concern, more concern whether to remove chlorine, organic matter and so on.
Northern temperature difference between summer and winter, winter minus ten degrees, easily lead to the cracking water purification equipment. Hardness particularly large cities, such as some cities and Shandong Zhengzhou, hardness, can reach more than 400, water is too hard, temperature is too low, will cause clogging of the reverse osmosis membrane accelerated. We encounter this case, open patch analysis, to see the salt crystal membrane surface.
high summer temperatures South, but also easily lead to activated carbon and membrane filter of bacteria, resulting in the case of stench smell. In addition to recommending customers often rinse water purifiers, water purifiers on the design, but also consider the needs of bacteriostatic.
removing water quality and temperature effects,Pressure mounted on the effects of water purifier is also very large, small water pressure resulting in a small water purifier water. Problems usually pure water booster pump less, no pump for some machines, the solution can be installed booster pump, or the use of a large flux of membrane elements, including ultrafiltration and reverse osmosis membranes.
and the pressure is too large, easily lead to damage or leakage water purifier, need to install the pressure reducing valve. Water pressure situation, and the more, the city water supply systems or associated with the housing.
