Prodynamic is a leading Taiwanese specialist in engineering and sales of liquid filtration and UV water treatment systems. The company will be located at booth A0919 and will be showing a demonstration UV disinfection system, as well as providing brochures of Hanovia’s new PureLine product range, designed specifically for the food and beverage industry.

As a scientific and technical leader in UV water treatment, Hanovia strives to deliver the best non-chemical disinfection technology to protect process and product water and syrup from harmful contaminants through its PureLine range. The range also provides dechlorination to increase the performance and prolong the lifetime of filters such as RO and GAC; it also provides de-ozonation to decrease the formation of carcinogenic by-products.

Hanovia’s UV disinfection products are designed and manufactured to the highest standard and are at the forefront of UV science and technology. Each UV system has at least one UV intensity monitor to ensure optimum performance. For the new PureLine system, an advanced dry monitor is located in a UV special sensor housing, allowing the controller to automatically correct the dose calculation as UV transmittance varies, without the need for an external UV transmittance monitor. It also provides absolute UV intensity monitoring in real-time and, because it remains in indirect contact with water, it can be removed and inspected without interrupting the process. The dry monitor also allows for field verification using a portable reference UV sensor. Moreover, the third-party validation, RED dose display, total treatment chamber and smart control are evidence of Hanovia’s world-class status.

In an increasingly regulated and safety-conscious market, the food, beverage and brewing industries have to meet ever more stringent standards of quality. Microbial growth due to contaminated water or ingredients can cause discolouration, off flavours and shortened shelf-life. The threat of contamination is further increased as manufacturers respond to demands for less chemical additives and preservatives. Effective microbial disinfection of the whole process is therefore essential.
 
A non-chemical disinfection method which is gaining increasing acceptance is ultraviolet (UV) disinfection. UV eliminates all known spoilage microorganisms, including bacteria, viruses, yeasts and moulds (and their spores). It is a low maintenance, environmentally friendly technology which eliminates the need for chemical treatment while ensuring high levels of disinfection.
 

How UV disinfection works

UV is the part of the electromagnetic spectrum between visible light and X-rays. The specific portion of the UV spectrum between 185-400nm (known as UV-C) has a strong germicidal effect, with peak effectiveness at 265nm. At these wavelengths UV eliminates microorganisms by penetrating their cell membranes and damaging the DNA, making them unable to reproduce and effectively killing them.
 
A typical UV disinfection system for process water or liquid ingredient consists of a UV lamp housed in a protective quartz sleeve and mounted within a cylindrical stainless steel chamber. The liquid to be treated enters at one end and passes along the entire length of the chamber before exiting at the other end. Virtually any liquid can be effectively treated with UV, including raw mains water, filtered process water, viscous sugar syrups, beverages and effluent.
 
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). The UV dose necessary for deactivation varies from one species to another and is measured in millijoules per square centimetre (mJ/cm²). Values for specific microorganisms have been experimentally established and are used to determine the type and size of UV system required.
 
The dose received by an organism in a UV treatment system is dependent on four main factors:
 

1. The energy output of the UV source
2. The flow rate of the fluid through the treatment chamber
3. The transmission value (ability to transmit UV light) of the fluid being treated
4. The geometry of the treatment chamber

By optimising these criteria, a UV system can be tailored to effectively treat large or small flows, as well as viscous fluids or those containing dissolved solids and high levels of starch or sugar compounds.
 
There are two main types of UV technology based on the type of UV lamps used: low pressure and medium pressure. Low pressure lamps have a monochromatic UV output (limited to a single wavelength at 254nm), whereas medium pressure lamps have a polychromatic UV output (with an output between 185-400nm).
 

Benefits of UV Disinfection

UV disinfection has many advantages over alternative methods. Unlike chemical treatment, UV does not introduce toxins or residues into process water and does not alter the chemical composition, taste, odour or pH of the fluid being disinfected.
 
UV treatment can be used for primary water disinfection or as a back-up for other water purification methods such as carbon filtration, reverse osmosis or pasteurisation. As UV has no residual effect, the best position for a treatment system is immediately prior to the point of use. This ensures incoming microbiological contaminants are destroyed and there is a minimal chance of post-treatment contamination.
 

UV applications in the food, beverage and brewing industries

Direct contact water

Although municipal water supplies are normally free from harmful or pathogenic microorganisms, this should not be assumed. In addition, water from private sources such as natural springs or boreholes could also be contaminated. Any water used as an ingredient in food or beverage products, or coming in direct contact with the product, can therefore be a source of contamination. UV disinfects this water without chemicals or pasteurisation. It also allows the re-use of process water, saving money and improving productivity without risking the quality of the product.
 

CIP (Clean-in-Place) rinse water

It is essential that the CIP final rinse water used to flush out foreign matter and disinfecting solutions is microbiologically safe. Fully automated UV disinfection systems can be integrated with CIP rinse cycles to ensure final rinse water does not reintroduce microbiological contaminants. Because of their high energy density, MP lamps are less affected by any sudden changes in the temperature of the CIP water than a LP lamp.
 

Filter disinfection

Reverse osmosis (RO) and granular activated carbon (GAC) are often used to filter process water, but can be a breeding ground for bacteria. UV is an effective way of disinfecting both stored RO and GAC filtered water
and has been used in the process industries for many years.
 

Dechlorination

GAC filters are also often used to dechlorinate process water, removing the ‘off’ flavours often associated with chlorine disinfection, meaning the flavour of the final product remains untainted and free from unwanted flavours or odours. Placing UV systems ahead of GAC filters used for dechlorination improves the performance of the filters and results in longer carbon runs, so decreasing operating costs.
 

Cooling media and chiller disinfection

Some meat and dairy products are subject to contamination after heat treatment or cooking. UV provides an excellent way to protect foods from contamination by contact-cooling fluids.
 

Sugar syrups

Sugar syrups can be a prime breeding ground for microorganisms. Although syrups with very high sugar content do not support microbial growth, any dormant spores may become active after the syrup has been diluted. Treating the syrup and dilution water with UV prior to use will ensure any dormant microorganisms are deactivated.
 

Liquid sweeteners

Sucrose-based sweeteners can be a prime breeding ground for microorganisms. UV systems are available specifically for treating these syrups.
 

De-aerated liquor

De-aerated liquor is added as part of a high gravity brewing process, often in the packaging operation. This liquor is added directly to the beer so needs to be kept free from contamination by gram negative bacteria, which can cause off-flavours and acidity.
 

Yeast preparation

The problems associated with yeast preparation in breweries are well recognised and include hazes, altered fermentation and surface membranes on packaged beer. A single cell of Sacchoromyces (var. Turbidans) in 16 million cells of pitching yeast will cause detectable hazes. UV destroys all known yeasts and their spores.
 

Waste water

Effluent from food, beverage and brewing facilities can be treated without the use of environmentally hazardous chemicals. This ensures all discharges meet with local environmental regulations. As already mentioned, because process water can be treated and re-used with UV, this also leads to a significant reduction in the amount of waste water produced.
 

Bromates and bottled water – UV as an alternative to ozonation

Hanovia has recently been working with Nongfu Spring Co. Ltd., one of China’s leading producers of bottled water and beverages, to supply UV systems for their production plants across China. This is a major milestone in the bottled water industry – particularly inChina– because presently in that country virtually all bottled water is disinfected using ozone. And around the world ozone is still the disinfection method of choice for many producers.
 
The decision by Nongfu Spring to opt for UV was driven by a number of reasons, not least of which was concerns about ozonation by-products such as bromate. In fact, Hanovia has noticed that more and more bottled water and soft drinks producers are now looking for ozone alternatives, and enquiries about UV are on the increase.
 
Bromide ions occur naturally in many spring waters and on their own pose no problem. However, the presence of ozone can cause conversion of bromide into bromate, with the consequent potential for consumer health problems. The World Health Organization (WHO) lists bromate as a carcinogenic substance and recommends its maximum limit in mineral water be set at 0.01mg/l (10ppb). In July 2008 the Chinese General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ), recommended in a revised draft national standard for drinking water and mineral water that a maximum limit for bromate in bottled water be in line the WHO guidelines. This limit has now been in force since October 2009.
 

Conclusion

Meeting the increasingly rigorous hygiene standards required in the production of food and beverage products 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.
 
UV disinfection systems are 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.

Hanovia’s UV technology is disinfecting cooling water in two of Formosa Chemical and Fibre Corporation’s factories in Taiwan. The UV systems are being used to reduce microbial contamination of cooling water used in the nylon manufacturing process.

“The cooling water comes into direct contact with the nylon fibre product so the quality of the water is essential,” says Hanovia’s Asia-Pacific manager, Ying Xu. “Since the Hanovia UV systems’ installation the water quality has been consistently high, with UV transmittance up from 95% to 98%. While UV itself does not reduce suspended solids in water, it reduces other impurities, so UV transmittance has improved. For applications such as this, a transmittance value of 98% is essential, and UV is playing an important role in maintaining this,” she added.

The UV units are located immediately after the heat exchange units and before the cooling tanks. This ensures all water leaving the heat exchanger is disinfected and cannot contaminate the rest of the cooling water loop. Each UV system can treat up to 50m³/hour and each is fitted with an automatic wiper which keeps the quartz sleeves surrounding the UV lamps clean.

There are currently four Hanovia UV systems in use, three in the Zhanghua factory and one in the Xingang facility, with two more systems planned for installation in Xingang.

All Hanovia UV units can be easily integrated into plant control systems. Maintenance requirements are minimal – typically the UV lamps only need replacing once a year, an easy operation which can be carried out by on-site personnel.

With ship owners worldwide contemplating a solution to the impending IMO Ballast Water convention, what better time for Hamworthy, international fluid handling specialist and Hanovia, specialists in UV treatment, to announce that they are joining forces to provide a robust technical solutions for this new market demand.

This partnership results from a strong relationship established over many years of working together on marine black and grey water systems. It recognises that Hamworthy’s experience in providing water treatment systems that meet environmental legislation, its worldwide sales and support network and Hanovia’s expertise in UV technology can be combined to provide ship owners with a flexible, cost effective solution to their ballast water treatment (BWT) needs.

Hanovia has been a leader in UV systems design and lamp manufacturing for over 80 years and has a long track record in tailoring UV systems to meet the demands of a wide range of industries including the marine sector where UV is already becoming established as one of the leading chemical free technologies for BWT. Medium Pressure UV is particularly advantageous, due to its small foot print, ease of maintenance and low capital and running costs.

Hanovia are one of the few UV system designers to make its own UV lamps and monitors, allowing Hanovia maximum scope to optimise a system to suit the specific ship requirements, as UV performance is critically dependent on the combination of UV light source, UV monitoring technology and chamber fluid dynamics.

Apart from the ever present need to perform to regulatory requirements under a wide range of seawater conditions, ship owners need a small footprint, configurable system that lends itself to both new build and retro-fitting into what remaining space there is on existing ships. The UV system is a key component in the BW management system and is integrated in the BW package by Hamworthy, who assume overall responsibility for performance compliance against the required regulatory standards

Hamworthy has over 40 years experience in marine sanitation and offer innovative solutions that meet all existing and anticipated standards. Their dedicated ballast water research and development team have introduced safe, energy efficient technologies that meet both current and future expectations. Hamworthy’s filtration technology, Hanovia’s UV system and the overall system control provided by Hamworthy represents a complete BWT solution. In addition Hamworthy provide a full turnkey service to offer support from system selection and engineering, though supply installation, commissioning and ongoing technical and aftersales support for the life of the equipment.

IMO approvals have progressed quickly and choosing a solution suitable to a range of differing ship types, sizes and environmental conditions can be challenging. The strategic alliance of Hanovia and Hamworthy provides a ballast water treatment solution that can assure ship owners of increased levels of protection for the marine environment anywhere in the world.
