ボトル入り飲料水生産のための水処理
前書き
市場レポートによると、ボトル入り飲料水の売上高は今後4年間でアジア、ラテンアメリカ、アフリカで最も急速に伸びると予測されています。世界の人口増加、特に発展途上国では、飲料水の需要が毎年増加しています。
ROTEKは、過去20年間、ボトル入り飲料水製造用の水処理システムを提供してきました。1つのソリューションとして水処理装置、充填、包装機械を提供する他の競合他社とは異なり、 ROTEKは、より信頼性の高い水処理技術のみに焦点を当てています。そして私達の水処理システムを通して高品質の水。
ROTEKは、次のようなさまざまな浄水技術を使用しています。
逆浸透、限外ろ過およびナノろ過プラント
メディアろ過、軟水化および化学薬品投与システム
スタンドアロンまたはROと組み合わせた電気脱イオン。
樹脂ベースのイオン交換システム
UVおよびコロナ放電オゾン衛生システム
Water consumption for each bed is calculated at approximately 50 liters per hour.
懸念事項
ボトル入り飲料水生産では、常に水質が主な関心事です。原水が飲料水の基準を満たしているかどうかを確認するには、原水品質分析を完了し、システム設計の推奨事項を送信する必要があります。
Rotek’s mission is to reduce all contaminants from the raw water to the level that meets standards of
The Association for the Advancement of Medical Instrumentation (AAMI).
What is Endotoxin?
Viable bacteria and endotoxins in water sometimes cause problems for human health. Endotoxins are major components of the outer cell wall of gram-negative bacteria. in medical procedures, especially hemodialysis (HD) and related therapies HDF and HF, endotoxins in the water for hemodialysis can permeate through the hemodialysis membrane and cause microinflammation or various related illnesses. To decrease such a biological risk, RO and UF membranes are generally used. Also, hot water disinfection.
Design Criteria
Based on the raw water quality analysis, we will provide our design suggestions followed by the 4 major treatment setups:
Filtration Systems
This section is responsible for filtering out most of the fine particles, heavy metals, chlorine, organic matter, bacteria, color & odors. The filtration system usually consists of a Clino-X Multimedia Sand Filter, Activated Carbon Filter, Water Softener, Ultra-Filtration System, Anti-Scale, and Chlorination Chemical Dosing Systems.
1st Pass Purification Systems
Reverse osmosis (RO) is a water purification technology that ROTEK uses most of the time for many industries. RO can remove many types of molecules and ions from solutions and is used in both industrial processes and to produce potable water. Depending on the raw water quality, if raw water TDS is below 50 ppm, then this section of the purification system may not be required as part of the design for bottled water production.
Remineralization Systems
Although RO removes everything from the water (including good and bad minerals),
however low-mineralized water has a few adverse effects:
- High corrosion potential
- Dietary deficiency causes risks of ischaemic heart and cerebrovascular disease (WHO, 2005a; WHO, 2006; Cotruvo, 2006)
The WHO recommends 10 mg/L of Magnesium and 30 mg/L of Calcium for drinking water. Therefore adding beneficial minerals to the product water is a process called remineralization. ROTEK uses natural minerals called "Camag" for adding pure Magnesium and Calcium to the product water with great improvement on the taste and pH level.
Disinfection Systems
The most common bacteria found in bottled water is Pseudomonas fluorescens, which is common in freshwater springs. It is not considered to be a health threat until you leave the bottle open for extended periods and the bacteria begin to react with the carcinogens in the plastic. Reducing bacteria and microbial to the minimum is the most important issue in the bottled water production business. ROTEK disinfection system consists of UV sterilizer, Nanosilver Activated Carbon, 0.2-micron filter, and ozone disinfection. With four levels of protection, the ROTEK disinfection system will make sure the bacteria level is reduced to nil before filling the bottle.
