As part of its environmentally conscious approach to brewing, Korea’s Hite Brewery Company has recently installed 25 Hanovia UV water disinfection systems at its Massan and Gangwan plants. The UV systems ensure water used in the production processes remains free from microbial contamination, ensuring a high quality, pure final product. Seven units are installed at Massan and 18 at Gangwan.

In Massan the UV is used to treat clean-in-place (CIP) water (three units), cooling water injected after the CIP (three units), and activated carbon-filtered water (one unit). At the Gangwan plant three UV units are used to treat water after deaeration and the remaining 15 units treat activated carbon-filtered water.

CIP is used for cleaning the interior surfaces of pipework, vessels, filters and other process equipment. CIP water must be completely free from microbial contamination, otherwise it could infect the whole system. As CIP uses very hot water, pipework and vessels need to be cooled down afterwards and before beer production can recommence. Cooling water also helps flushes out the remaining CIP water, which contains acid and caustic soda. The purity of the cooling water is therefore extremely important to prevent any residual contamination.

Activated carbon is commonly used in water treatment for decolouring and deodorisation, due to its strong adsorption properties. This adsorption can also remove residual chlorine from the water, leaving the post-filter water vulnerable to microbial contamination. UV therefore plays a vital role in ensuring the post-filter water is adequately disinfected.

Deaeration removes dissolved oxygen from water prior to the addition of yeast, a key part of the brewing process. Any contamination of the deaeration water could kill the yeast, meaning the whole batch would have to be destroyed. UV is ideal for this step as it is quick acting and effective without producing any unwanted disinfection by-products which could affect the yeast.

“When Hite was considering UV for the first time it looked at a number of UV system suppliers,” commented Ying Xu, Hanovia’s Asia Pacific Sales Manager. “We were selected as our UV systems not only produced the highest microbial reduction rates, but we also offer a comprehensive and cost-effective spare parts and maintenance service. Hite now uses over 45 Hanovia UV systems in its breweries across Korea, including the latest project at Massan and Gangwan.”

“According to the company it also needs to do CIP less frequently, it uses less preservative in the finished product, and the final water has no unwanted residuals, so the taste and colour is not altered in any way. This all adds up to a cleaner, greener process and product,” she added.

The benefits of UV

Meeting the increasingly rigorous hygiene standards required in the brewing and beverage industries is a real challenge. If improvements need to be made to plant and equipment, they need to bring quick returns on the investment and measurable improvements in product quality.

For manufacturers seeking to improve the quality of the end product, UV is an economic, realistic option. It is an established method of disinfecting drinking water throughout the world, and is also widely used for high purity applications such as pharmaceutical processing and microchip manufacturing, where water of the highest quality is essential.

There are no microorganisms known to be resistant to UV – this includes pathogenic bacteria such as Listeria, Legionella and Cryptosporidium (and its spores, which are resistant to chlorination).

UV disinfection systems are also easy to install, with minimum disruption to the plant. They need very little maintenance, the only requirement being replacement of the UV lamps every 9 – 12 months, depending on use. This is a simple operation that takes only a few minutes and can be carried out by general maintenance staff.

Novotel Saigon Centre chooses Hanovia UV technology

Novotel’s flagship Saigon Centre hotel in Ho Chi Minh City, Vietnam, has recently installed six Hanovia UV systems for service water treatment. The UV systems kill any microorganisms from the incoming city water supply, leaving it good enough to drink. All the UV systems provide a minimum 99.999% reduction in E.coli, Cryptosporidium, Giardia, Legionella and other harmful microorganisms.

Tourism is a flourishing industry in Vietnam, with over a third of all visitors coming from Europe, where water quality is taken for granted. Currently, only 22% of hotel guests are Vietnamese, with 34% from Europe, 8.6% from North America and 9.5% from Oceania [1]. Having water of a drinking quality standard is therefore a high priority for the leading hotel chains operating in Vietnam.

Microbial control in hotel and other building service water is a serious but easily overlooked problem. Hong Kong’s new government headquarters, for example, were recently contaminated by Legionella, which resides in buildings’ water cooling towers and pipes [2]. The same microbes were also found in other buildings in Hong Kong [3]. Most recently, three children at a Hong Kong school were infected by Staphylococcus aureus, a common water-borne bacteria. An update of the school’s water disinfection system is now required [4].

“Hotels across the Asia-Pacific region are now taking extra precautions to ensure their water meets the World Health Organisation’s drinking water quality guidelines and to ensure their guests’ health and safety,” commented Hanovia’s Asia Pacific Manager Ying Xu.

“Even though hotel tap water is not intended for drinking purposes, UV provides that extra level of health and safety for residents in case they inadvertently drink the water, such as while brushing their teeth, or inhale water aerosol while showering. UV is in fact the WHO’s recommended disinfection method for Cryptosporidium and Giardia removal. It is already widely used to remove both microorganisms from water supplies in the European Union and United States. Water standards in Vietnam do not include Cryptosporidium and Giardia [5], but the Novotel chain sees the importance in conforming to the WHO’s standards,” she concluded.

Traditionally, hotel water in Vietnam has been treated with chlorine. While this kills most microorganisms, it is ineffective against Cryptosporidium and Giardia, both of which are extremely hazardous to human health, causing severe diarrhoea, vomiting and fever, which can last for a month or more. Water treatment experts were unaware of the limitations of traditional chlorine disinfection until recent years. Chlorination can also affect the taste and smell of water if doses are too high.

In this installation, six, single-lamp AF3 amalgam UV systems are installed on the hotel’s roof, treating water flows between 26.5 m3/h and 30 m3/h. City water passes through sand filters before storage in roof tanks, from where it passes through the UV systems prior to distribution to every room in the hotel. These UV systems are very small and can be installed in the tightest of places.

A major advantage of using UV is its low operational cost. For example, 166 m3/hr of water is treated at the hotel. As the six UV systems only consume 1.62 kW of power between them, for every 1 m3 of treated water, the UV system consumes less than 0.01 kWh of power, which is approximately 0.1 US cents per m3.

Commenting on the installation, Hanovia’s Managing Director John Ryan said: “This is yet another successful hotel project and reinforces our expertise as suppliers of UV technology that can be used across the board: from potable-standard water in hotel rooms to chloramine-free water in hotel pools and spas.”

Dairy Plus Co. Ltd. in Thailand has replaced its chlorine-based disinfection system with medium pressure UV technology from Hanovia. The company decided to reduce high levels of chlorine dosage throughout the process because it was proving ineffective at removing all microorganisms, particularly in the rainy season. It was also producing an after-taste in the product.

Water to the plant is from two sources: city water and deep well water. The chlorine is only dosed at the raw water feed level, firstly after the clarifier for pre-chlorination and then some low concentration dosing after the softener.

“The incoming city water in particular has a high microbial contact – often as much as 20,000 cfu/ml in the rainy season,” commented Ying Xu, Hanovia’s Asia-Pacific Sales Manager. “At these times, high chlorine doses of even 8ppm were still resulting in microbial concentrations over 6,000 cfu/ml. Something therefore had to be done, and that’s where UV was able to help.

“UV, which is a non-chemical disinfection process, was brought to the attention of Dairy Plus by our local distributor,” continued Miss Xu. “When Dairy Plus saw the advantages of our medium pressure UV systems, which effectively remove microorganisms without any problems of after-taste or re-infection, the company decided to switch from chlorine to UV as its main disinfection method.”

Five Hanovia UV systems are installed at the plant – four duty and one standby. Two units disinfect clean-in-place (CIP) water and two are used for treating dairy mixing water. Each UV system treats up to 130m³/hour of water. As mentioned there are two sources of raw water being used with two feeds coming out of the city water source.

 
City water source: (two feeds)

Feed 1: City water > Clarifier > Sand filter >Carbon Filter>Chlorination>Storage tank

Feed 2: City water >UF Filter>Chlorination>Storage tank

Storage tank (Feed 1 combined with Feed 2) > Softener No.1> Low Dosed Chlorination>Bag Filter>Storage tank of Softener No.1> UV1 > UV2 > CIP (Clean-in-place)

Deep well water: (one feed)

Deep well water > Deion filter > Carbon filter > Chlorination>Storage Tank>Softener No.2>Low Dosed Chlorination>Bag Filter>Storage Tank>UV3 > UV4 > Mixing with final product

Bacteria targeted for reduction include E. coli and many other common water-borne coliforms; the expected level of bacterial reduction is a total plate count of <50 cfu/ml.

“One of the main reasons Dairy Plus selected Hanovia in particular was down to the efforts of our local distributor, who helped resolve a number of initial complications. Our products are also recognised as offering the most advanced technology for high purity food and beverage applications like this,” added Ms Xu.

“Since our systems were installed the customer is very satisfied with their performance, reporting that the units are running well and producing excellent disinfection results. The company is particularly impressed by the low maintenance costs, the high energy output of the systems, and the fact that the frequency of CIP procedures has been dramatically reduced, meaning less down-time of the manufacturing process,” she concluded.
