Problems solved by technology

All of these methods have a major disadvantage: if you ozonize bottled water, bromates form mainly in the bottle, and obviously it is impossible to remove them once they form
[0022] The third disadvantage is the filtration process, which will cause the ozone to decompose, and the ozonated water may be recontaminated, because of the easy growth of bacterial

Embodiment 1

[0099] Embodiment 1: be used for the method for disinfection Protosalis F, H and I

[0100] Salicam F, H and I were bottled in different types of bottles in three different bottled water production units equipped with the same disinfection method, illustrated in Figure 10 middle. For each type of water, raw water is pumped from the well to the raw water tank (1). The water pump (3) supplies water to the buffer tank (2) at a constant flow rate. After (3), in order to inhale carbon dioxide at a constant flow, part of the water is diverted to the water pump (13), whose function is to generate a constant water flow through the venturi (14). Static mixer (15) mixes CO 2 and water, the static mixer (10) mixes the diverted water with the remainder of the main stream. After (10), part of the water is diverted to a flow meter (107), which monitors the water flow generated by the gas-liquid mixing pump (7). An ozone generator (101) fed with air generates ozone. Ozone flow is mo...

Embodiment 2

[0104] Embodiment 2: the method for disinfection raw water sample E

[0105] In the experiment of Example 2, the water sample E was filled in a 1500mL PET bottle. During the experiment, the natural CO in water sample E 2 The content is 5-15mg / L, without adding CO 2 , the pH was maintained at 7.1-7.3. use Figure 11 Illustrated bottled water production plant for ozonation. Raw water is stored in the raw water tank (1) and is pumped to the buffer tank (2) with a centrifugal pump (3) in stop and run mode. In order for the Venturi (7) to generate constant suction, a portion of the water is diverted from the mains flow to the pump (108). Ozone is generated from air by a vacuum type ozone generator (101), and the generated ozone is delivered to the Venturi when the Venturi is sucked. A check valve (106) is installed to prevent water from entering the ozone line when the venturi is not pumping. After ozone injection, the water of the branch stream mixes with the water of the...

Embodiment 3

[0109] Embodiment 3: the method for disinfection raw water sample E

[0110] The experiment of Example 2 was repeated during the 21 hours, recording the level of ozone in the finished product immediately after filling and the level of bromate in the finished product as in Figure 12 shown in . Ozone levels in the bottles were the target level of 0.10 ± 0.05 mg / L during the entire time period, resulting in bromate at safe levels (90% of the results were below 5 μg / L.

Abstract

The invention relates to a process for producing bottled water sterilized by ozone, which comprises the following continuous steps: gathering original water in an original water tank (1), and pumping the water from the original water tank (1) to a buffer tank (2); injecting ozone before the water is pumped to the buffer tank (2); bottling the ozonized water through a filling machine after the water is pumped to the buffer tank (2). The process is characterized in that the water flow is maintained at a constant value between the original water tank (1) and the buffer tank (2), and the ozone which has stable concentration and can be transiently used is injected in the water.

Description

technical field [0001] The invention relates to a bottled water production process using an ozone disinfection process. Background technique [0002] Ozone (O 3 ) is a very widely used disinfectant in the bottled water industry because of its strong bactericidal effect. This superior disinfectant inactivates more resistant pathogenic microorganisms such as protozoa (e.g. Cryptosporidium parvum) and viruses by disrupting cell membranes. By dissolving ozone into the water before filling, it is possible for the ozone to sanitize the water itself as well as the bottle and cap when it is filled. The ozone decomposes very slowly in the bottle, providing sufficient contact time for the disinfection of the bottle and cap, and after a few hours, the ozone is completely decomposed, leaving only odorless, tasteless and harmless oxygen in the bottle. Such products are microbiologically safe for consumers. [0003] However, generally among all oxidants used for water disinfection, oz...
