Method for processing hot alkaline spring water

Abstract

The invention discloses a method for processing hot alkaline spring water. The method comprises the steps of (1) decreasing temperature; (2) aerating; (3) adding ozone for the first time; (4) filtering; (5) adding ozone for the second time; and (6) filling for packaging. According to the method, the tower-type aeration and two times of ozone adding are adopted, and during the processing procedure, aeration quantity, ozone using amount, adding mode and contact time are controlled scientifically, so that the original rich mineral substances in mineral spring are maintained, the formation of bromate is inhibited effectively, the sedimentation of mineral substances can not be generated, and the alkaline spring water which is processed and packaged conforms to the related national standard requirements. According to the invention, the effective method for processing the hot alkaline spring water is provided, the treatment process is simplified, the processing cost is lowered, and under the condition that the various mineral substances in water can be kept constant, pathogenic bacterium can be killed effectively, the formation of bromate is inhibited, the sedimentation of the mineral substances can be eliminated, and the appearance, the mouthfeeling and the quality of the packaged water can be improved obviously.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and specifically refers to a method for treating hot alkaline spring water. Background technique [0002] Alkaline spring water is named because of its alkaline pH value. From the perspective of medicine and human health care, alkaline water has attracted more and more attention. There are not many hot alkaline spring water resources that can be directly drunk in nature, mainly because most hot mineral springs or alkaline springs have high salinity, high hardness and high carbon dioxide, and it is difficult to reach the relevant bottles in our country with conventional treatment processes. (barreled) drinking water standard requirements. [0003] In recent years, various alkaline waters have appeared on the market, but most of them are artificially prepared soda water. The reasons are as follows: first, natural alkaline spring water resources are very limited; second, natural alkaline wa...

AI Technical Summary

Problems solved by technology

The problems in the above process are as follows: First, most hot alkaline spring water will have different types of mineral precipitation after packaging, which will affect the sensory indicators of the finished product; second, the traditional mixing tower ozone dosing method is difficult to dissolve effectively The third is that bromate will be produced by adding ozone for a long time or in large quantities, which will cause bromate in the treated alkaline spring water to exceed the standard. Usually, the content of bromate is above 100μg / L

Therefore, the existing hot alkaline spring water production process is difficult to meet the production requirements of bottled alkaline spring water and the current relevant standards
