Water purifiers wat pollution so seve it dispensable
Water is the source of human life, people living without water. However, drinking contaminated water, people will have the disease and even death. Pollution
the sea water intrusion and intrusion. Salt water intrusion refers to sea water intrusion of freshwater aquifers phenomenon. The main cause of sea salt water intrusion is the excessive exploitation of ground water fresh water. If the over-exploitation of underground fresh water, coastal or island on fresh water - seawater interface can be in an unbalanced state. my countrys northern coastal region, into 80 years, consecutive years of drought, low rainfall, reducing groundwater recharge, but industrial and agricultural water consumption has to be increased, fresh groundwater "make ends meet", resulting in seawater intrusion.
Industrial "waste" (waste water, waste) is a major factor groundwater contamination. Industrial waste such as industrial wastewater, industrial pickling sewage, industrial waste smelting, light industry and petrochemical wastewater without organic wastewater treatment and municipal sewers, rivers and lakes or directly into the ditch, big seepage pit, resulting in groundwater chemistry Pollution.
due to the agricultural activities caused by groundwater pollution sources include soil residual pesticides, fertilizers, animal and plant remains decomposition and irrational sewage irrigation. They cause a large area of 鈥嬧€媠hallow underground water quality deterioration, the most important is the pollution of pesticides and fertilizers.
side is the economy continues to develop, a lot of plastic, metal, batteries and other indigestible new garbage appeared, one side is the lack of infrastructure and regulation, rural sewage, garbage straight row phenomenon is more serious. With garbage sun and rain and surface runoff washing, dissolution was slowly into the ground, pollute groundwater.
As consumers, we have neither the means to control water pollution, it is impossible to supervise the process water, but no way to detect the quality of commercially bottled bottled water, then the method used to make own drink safe water? water to a boil. High temperatures against bacteria, but does not remove heavy metals and other toxic byproducts of inorganic and sterilized. Thus, boiling water is only necessary but not sufficient conditions for processing drinking water, if water is not pure, preferably other additional purification measures, for example, to install a water purifier?
using the water purifier, the water can filter impurities the drinking waterStandard drink reach, and lower cost. Water purifier filter used is a purely physical way, can effectively remove various types of impurities in water, such as bacteria, chlorine, heavy metals, scale (calcium and magnesium, etc.), volatile substances, rust, sand and the like. Water purifier filter absolute cost is much lower than bottled water, but the water good taste, can be drunk directly without boiling, so the family is the best drinking water treatment program.
