Description
Technical Field
The utility model relates to the field of water treatment, in particular to a water treatment device with backwashing function.
Background
In the commercial fields of coffee shops, milk tea shops and the like, at present, after tap water is boiled by a water boiler, coffee and milk tea are brewed by directly using boiled water. Tap water is obtained by treating raw water from a water source such as a river, a lake, or a river by a water supply company, and since the water supply company uses chlorine to treat harmful substances such as impurities in the raw water in the water source, a small amount of impurities, residual chlorine, and the like inevitably exist in the tap water. Even if the tap water is boiled by the water boiler, a little impurity still exists in the boiled tap water, the impurities and residual chlorine remaining in the tap water affect the quality and taste of coffee and milk tea, for example, the residual chlorine causes peculiar smell in the tap water to affect the taste of the coffee and milk tea, the residual chlorine even affects human health, and the impurities such as calcium and magnesium ions remaining in the tap water cause the water boiler to be blocked. In addition, some merchants can directly use tap water to make ice in order to save cost, which directly results in impurities and residual chlorine being left in ice blocks to seriously affect the health of consumers.
In order to avoid the adverse effect of tap water on coffee, some coffee shops brew coffee with distilled water, mineral water, or the like. The high purity of the distilled water tends to increase the extraction rate of coffee, and tends to cause the extraction of the component that should not be extracted, which once occurred directly affects the taste of coffee, for example, when the component that should not be extracted is extracted, the taste of coffee tends to be bitter and the coffee tends to be strong. Although mineral water is not as pure as distilled water and does not cause the problem of coffee brewed with distilled water, mineral water contains calcium, magnesium and other components, which makes water harder and makes it difficult to develop coffee flavor.
