Water preparation technology of metasilicic acid-enriched low-scale mineral water

Abstract

The invention provides a water preparation technology of metasilicic acid-enriched low-scale mineral water, and belongs to the technical field of drinking water purification. A technical process comprises thefollowing steps: raw water selection, deep well water taking, rough filtering, safety filtration, nanofiltration, UHT (Ultra High Treated) heating, cooling, fine filtration, UV (Ultraviolet) sterilization, terminal filtration and low-scale mineral water product obtaining, wherein raw water is selected from natural drinking mineral water which is rich in metasilicic acid. According to the water preparation technology provided by the invention, produced water is the metasilicic acid-enriched low-scale mineral water and is suitable for long-time drinking, and the nutrition is better thanthat of existing purified water and other drinking water; the produced water is subjected to fine filtration for removing scales after being subjected to the nanofiltration and the UHT heating, the scaling coefficient is extremely low, the taste and the appearance are improved, the metasilicic acid-enriched low-scale mineral water is more suitable for cooking tea and cooking porridge, and the metasilicic acid-enriched low-scale mineral water is clear and bright in water quality and is eyeable; the produced water is subjected to UHT high-temperature sterilization and then is subjected to medium-pressure UV sterilization and the terminal filtration sterilization, the sterilization modes are all physical sterilization, harmful matters such as bromateor trihalomethane cannot exist in the water, and the quality is safer; the produced water can be encapsulated into packaged drinking water and can also be used as direct drinking water which is piped into homes, and the adaptation of the product is stronger.

Description

technical field [0001] The patent of the invention belongs to the technical field of drinking water purification, and in particular relates to a water treatment process of metasilicate-rich low-scale mineral water. Background technique [0002] At present, the production process of natural drinking mineral water basically uses raw water to be sterilized by ozone after coarse filtration and fine filtration. This process depends on the quality and safety of raw water, which has certain limitations for mineral water enterprises. Once encountering high hardness mineral water raw water , Drinking the water after boiling will bring consumers perception and inconvenience in use; and ozone sterilization is suitable for raw water with low bromide ion content in water, and improper control will cause the hidden danger of bromate exceeding the standard. [0003] Requirements for high-end drinking water: 1. Safety; 2. Nutrition; 3. Enjoyment. [0004] For raw mineral water with high ha...

Problems solved by technology

[0007] In view of the advantages of cool boiled water, research on cool boiled water has appeared in the market. For example, Chinese patent 201510910166.1 uses microwave heating to produce "cool boiled" purified water; and Chinese patent 201610678449.2 uses UHT heating to produce "cool boiled" drinking water, but these two None of these products is mineral water, and there are still many deficiencies in the nutrition of water (such as the minerals and trace elements needed by the human body), the improvement of water taste, the appearance of water, and the quality and safety of water.
