High speed for UV light.

Ametek Vision Research has introduced high-speed cameras capable of capturing images in the extended light spectrum of UV, visible and Near-IR wavelengths. The cameras have over 70% Quantum Efficiency (QE) at 300nm, as well as unprecedented QE at other points of the UV light spectrum, allowing researchers to potentially capture images using just the camera and a UV lens. Previously, images in the UV light spectrum were only available with the aid of an image intensifier. The cameras are also capable of capturing images in the visible and near IR spectrums with performance similar to the equivalent Phantom cameras*. Depending on lab needs, the cameras can offer a two-in-one benefit.

“We’re excited to bring this UV-extended capability to the scientific community. This community often works in cutting-edge applications that rely on our cameras to provide the best results. As the leader in high-speed imaging, it is incumbent upon us to bring technical advances in our cameras that make a difference and propel their research forward. The UV-extended capability cameras can do just that,” explained Kevin Gann President of Research and Development at Vision Research.

Phenomena such as some chemical reactions are visible only at certain wavelengths in the UV light spectrum. While high-speed cameras would be advantageous to analyze the very fast reactions, high-speed sensors typically have glass covers that block the UV wavelengths. Similarly, standard lenses are constructed of glass, also blocking UV light. Researchers previously needed to couple an image intensifier to a standard camera to compensate for the glass. Phantom UV cameras overcome this obstacle by implementing a different cover material — fused silica — that allows penetration of UV wavelengths. The cover material is combined with specific Phantom Back Side Illuminated (BSI) sensor designs to provide high QE. Depending on the UV signal generated by the event, an intensifier may no longer be required.

*The UV-extended capability is available on the Phantom TMX Series (TMX 7510, 6410 and 5010), the T3610 and T2410, providing a broad performance range to from which to choose.

UV keeps Nirvana pure.

Nirvana Spa in Berkshire is one of Britain's most prestigious spa facilities, frequented by elite athletes and celebrities. The facility has a reputation for using crystal clear natural mineral water drawn from the same pristine source 700 feet beneath the spa. To maintain the purity of the water within each of its nine pools, the spa is using the latest ultraviolet (UV) disinfection systems from Hanovia.

The spa has a broad range of pools, including Roman and surf rooms, a plunge pool, fitness pool, outside pool and hydrotherapy pool. Each has a specifically-sized Hanovia UV system installed to treat the water, ensuring the high level of quality and disinfection required.

“The Celestial Floatation Pool, which is the UK’s largest hydrotherapy pool, is unusual because it contains salt imported from the Dead Sea,” commented Neil Phelps, Nirvana’s Maintenance Manager. “We match the specific gravity of the Dead Sea. The high salt concentration makes objects very buoyant in the water and floating in the pool is perfect for spinal alignment. Bathers in the warm, mineral-rich waters are removed from most external stimuli and a gentle current gives the sensation of floating in space. This provides both mental and physical benefits and many sports men and women, including international rugby players, skiers and rowers, use the pool to enhance performance and reduce injury time.”

“UV disinfection systems allow us to run the chlorine at the right levels and there is no way we would be able to achieve the level of water purity without them. As the water temperature is kept at a constant 35°C, which is higher than in leisure pools, there is an increased risk of infection from microorganisms such as bacteria and moulds which thrive in warm water. Microbiological control is a key aspect of the water quality. UV plays an important part in that control and bacteriological checks are carried out regularly.

“Hanovia’s UV systems enable us to achieve exemplary water quality in all of our pools. This, coupled with Hanovia’s outstanding aftersales service, gives us, the maintenance team, the reassurance to maintain the high level of water quality and disinfection required,” concluded Neil.

UV is highly effective at killing any bacteria, viruses or moulds in the water, including Cryptosporidium and its spores, which are chlorine-resistant. This reduces problems associated with chlorine by-products such as chloramines, which are formed when free chlorine reacts with sweat or urine in pool water. Trichloramines in particular are powerful irritants which are responsible for eye and respiratory complaints and the unpleasant ‘chlorine smell’ commonly associated with indoor pools. It also means the water is much clearer than that found in traditionally chlorinated pools.

Each Hanovia UV system installed at Nirvana Spa consists of a stainless steel chamber containing a medium pressure UV lamp housed in a special quartz sleeve to protect it from the pool water. The chambers are carefully designed by Hanovia engineers using advanced flow calculation methods. This ensures maximum performance by making sure all the water flowing through the chambers receives the correct UV dose. UV technology provides a cost-effective and low-maintenance alternative to other water treatment systems such as ozone.

United for UV disinfection!

Hanovia Limited and Berson Milieutechniek B.V., both part of Halma plc, have merged to create a new unified company providing ultraviolet (UV) disinfection systems. The new combined company will offer customers a more comprehensive product portfolio, backed by an expanded distribution capability and a larger network of approved UVCare™ support centres around the world.

Hanovia and Berson, which have previously operated independently as part of Halma plc, retain their trading names following the merger. The new merged company has more than 150 years of combined experience in developing and applying UV technology, and has many thousands of installations within industrial and municipal water treatment applications globally.

Founded in 1924, Hanovia is recognised as a world leader in UV disinfection and chemical reduction technology. Its advanced UV systems are used in a wide range of industrial, aquatic and leisure applications, and it provides unparalleled customer care via its UVCare service. Hanovia’s headquarters are in Slough (GB) and it has regional offices in Germany, USA, Singapore and China. Berson, founded in 1972, provides UV systems with a reputation for technical innovation, quality and service. As well as water and wastewater treatment systems, it manufactures specialist UV insect extermination systems for industrial catering and food service facilities. Its head office is in Nuenen, (NL), and it has regional offices in the US and China.

At Aquatech, Amsterdam

“For 10 years Hanovia and Berson have been dedicated to developing the industrial and municipal markets respectively. That dedication has created a deep competence in their respective markets. Now we have unified the two companies, to have a greater critical mass to pursue our overarching purpose of protecting the world’s critical resources from harmful contamination,” said John Ryan, Managing Director of the merged companies.

“Our goal is to deliver application-optimised UV solutions to our customers, and combining our products and our engineering capabilities allows us to accelerate that development. The greatest opportunity to come from the unification is to combine field resources so that we can deliver a step change to our UV Care programme. Our organisations based in the USA, Europe and China put resources closer to our customers so that we can provide speedy and comprehensive support and take local feedback into the design of our new products,” said Tim McDougle, Marketing and Sales Director. “This is truly an exciting time for us as we position ourselves to give our customers the global support they deserve.”

The Hanovia facility in Britain will be the global headquarters for the combined company, whilst also becoming its centre of innovation. Nuenen will now be the new sales and support HQ for the EMEA region. The Hanovia office in Shanghai, China, will remain as the company’s Asia headquarters, serving industrial and now municipal markets.

UV disinfection simplifies water treatment.

Berson and Hanovia have jointly launched a new low-pressure UV disinfection system for the treatment of municipal, re-use and waste water. The easy-to-install AmaLine R UV range has been third-party validated, in line with US EPA and NWRI guidelines. It provides effective treatment, while reducing lifecycle costs through being simple to maintain and extremely energy efficient. Unlike other similar systems, the AmaLine has been designed to simplify maintenance, which can be performed by a single operator rather than a crew, and without requiring external lifting equipment.

The AmaLine range is application-optimised in terms of its design and operation, with a flow range of 1-30 MGD (millions of gallons per day). The AmaLine R has a U-shaped chamber that optimises flow to cater for low UV light transmittance (UVT) water quality. This makes it ideal for re-use and waste water applications.

Also available is the AmaLine D range, designed specifically for municipal drinking water, which has a coaxial flow L-shaped chamber, and optimises flow to deliver the most effective disinfection for drinking water applications.

AmaLine has been designed using the latest computational fluid dynamics (CFD) modelling. A highly efficient chamber and optimised lamp positioning ensure maximum energy efficiency. Optimum distribution of UV intensity throughout the chamber provides effective water treatment.

AmaLine uses LPHO (low pressure high output) amalgam lamp technology that provides variable output ballasts (50 to 100%). This helps to reduce energy consumption further, but also provides greater UV intensity. Shorter physical lengths compared with conventional low-pressure lamps reduces the overall footprint of the system. The ability to leave LPHO lamps on, even when there is no flow, helps to minimise potential disruption to the process. The longer life amalgam lamp helps to extend the periods between servicing.

AmaLine is also much easier to service and maintain. In contrast with alternative solutions, the AmaLine system has been designed to enable a single operator to change lamps, quartz sleeve and wiper blades easily and safely without the need of cranes, hoists or other external lifting equipment. A unique lamp connector, with self-aligning functionality, enables simple and fast lamp replacement, helping to minimise downtime, protect an operator from harm during servicing, and provide assurance of optimal system operation.

Where Berson has been focused on the municipal market and Hanovia on industrial, both companies now will focus on all markets with joint resources. This will now increase the capability to develop products for various applications quicker, and provide extensive support globally. The AmaLine is a platform that has been designed for the municipal market but has been engineered so it can be adapted for specific industrial applications.

Monitoring sulfur dioxide.

As part of its comprehensive emissions monitoring analyser range, Servomex offers the SERVOPRO SO2, an analyser that uses pulsed Ultraviolet (UV) Fluorescence technology to deliver a reliable, continuous measurement of ultra-low sulfur dioxide in emissions and ambient air.

The analyser’s measurement is based upon UV radiation of the sulfur dioxide molecule using light in the range of 190-230 nm. The molecule absorbs the light into an excited state and then decays back down to the ground state, where a photomultiplier tube (PMT) converts the signal into SO2 concentration.

To prevent interference and quenching from polycyclic aromatic hydrocarbons (PAHs) such as naphthalene, the SERVOPRO SO2 is fitted with a “kicker” to remove them from the sample before analysis, ensuring a reliable, accurate reading.

The analyser is designed to slot seamlessly into analyser racks, making it easy to integrate with existing emissions monitoring systems, and offers comprehensive data logging and remote viewing of more than 200 operational parameters.

The operational status of the analyser can be seen at a glance thanks to an instant-response lighting system.

Barbara Marshik, Servomex’s Market Segment Manager – Power, said: “The SERVOPRO SO2 is designed for ultra-low SO2 emissions monitoring, delivering superior performance for a low cost of ownership. It uses proven technology to deliver a continuous measurement you can rely on.”

The SERVOPRO SO2 is part of Servomex’s emissions monitoring analyzer range set to meet the lower regulatory requirements, joining the SERVOPRO NOx, which uses Chemiluminescence Detection, the heated-oven, Flame Ionization Detection-based HFID, and the SERVOPRO 4900 multi-gas analyzer to offer a comprehensive solution for the monitoring of NO, NO2, NOx, O2, SO2, methane, total hydrocarbons, and non-methane hydrocarbons in a diverse range of industrial and vehicle applications.

Keeping your swimming pool clear!

Langley Leisure Centre in Berkshire (GB) is the first leisure centre in that country to use an optimised low energy UV system to treat water for its 25-metre indoor heated pool. The Hanovia SwimLine Ultraviolet Energy Optimised (UVEO) system is helping to provide high quality water that reduces corrosion and creates a healthier environment for bathers, whilst reducing overall energy consumption.

Langley Leisure Centre in Berkshire, England

The new SwimLine UVEO uses up to 60% less power than conventional UV systems, with just a single UV lamp. This means reduced running costs for 24/7 applications such as swimming pools, without compromising on bio-security or chloramine control. The system is optimised specifically for pool bio-safety to ensure chlorine-resistant organisms such as cryptosporidium and giardia are controlled with the optimum UV dose.

Hanovia SwimLine UVEO system

Commenting on the Hanovia UVEO system, a spokesperson from Langley Leisure Centre said: “Since we installed the Hanovia SwimLine system there have been noticeable energy savings. The performance of the system excellent and it is also very easy to use and maintain. Added to that, we have been impressed by the company’s professional after-sales service.

“The optimised medium pressure UV lamp provides excellent chloramine reduction, ensuring the effective control of these unpleasant by-products of chlorine dosing which are responsible for the typical ‘chlorine smell’, red, stinging eyes and skin irritations. Controlling chloramines has also delivered high quality pool water, reduced corrosion of metal structures and a healthier environment for bathers.”

The SwimLine UVEO is available in a range of sizes and treatment capacities to meet the needs of different pool sizes. The system is designed for easy installation into existing pipework, matching pipe velocities and turnover rates for any pool. It is also fitted with an internal auto-wiper which maintains UV output efficiency by regularly cleaning the quartz sleeve housing the UV lamp. Lamp replacement is also quick and easy, with the system designed to allow easy access, even in small plant rooms.

UV is highly effective at killing any bacteria, viruses or moulds in the water, including cryptosporidium and its spores, which are chlorine-resistant. Another major advantage of UV is that it considerably reduces the amount of chlorine required to maintain hygiene levels. This reduces problems associated with chlorine by-products such as chloramines, which are formed when free chlorine reacts with sweat or urine in pool water. Trichloramines in particular are powerful irritants which are responsible for eye and respiratory complaints and the unpleasant ‘chlorine smell’ commonly associated with indoor pools. It also means the water is much clear than that in traditionally chlorinated pools.

Ensuring bottled beverage safety!

In an increasingly regulated and safety-conscious market, legislation such as the EU Directive for Bottled Water 98/88/EC (1998) drives the beverage industry 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.

To meet this requirement, Cott Beverages has been using Hanovia UV disinfection technology to treat process water used in the production process. The company decided to use UV technology to ensure final product security prior to mixing and bottling and has been very satisfied with the performance of the UV systems.

“The Hanovia UV systems have been easy to integrate, maintain and operate,” said Chris Prentice, site service engineer at Cott Beverages. “They provide us with absolute insurance before bottling by making sure that we are producing and maintaining a high-quality product, which is essential for our brand.”

Hanovia’s PureLine UV is an intelligent system that is optimised for the beverage industry to simplify the treatment of water, sugar syrup, brine and even reducing chlorine and ozone. Critically, 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). 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 is used for both primary disinfection or as a back-up for other purification methods such as carbon filtration, reverse osmosis or pasteurisation. Because 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 disinfection systems are easy to install, with minimum disruption to the plant. They need very little maintenance, the only requirement being the 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 trained general maintenance staff. Hanovia’s UVCare™ training programme supports businesses like Cott Beverages to make sure servicing is carried out by certified engineers.

UV disinfection in industry.

Hanovia* is to host a webinar aimed at helping manufacturers optimise the removal of chlorine within their water treatment operations. The 60-minute interactive presentation by Tim McDougle, Hanovia’s Sales & Marketing Director and James Hadley Hanovia’s Western European Sales Manager, takes place on the 23rd May 2017 and will outline how UV dechlorination can reduce water treatment maintenance and lifecycle costs while providing enhanced protection against bio-contamination.

Hygienic applications such as pharmaceutical and food and beverage manufacturing desire clean water treatment technologies with minimal bacteria build-up and downtime. Combining pre-treatment with Reverse Osmosis is common practice for removing a broad range of inorganic and organic impurities and the addition of Electro-deionisation (EDI) in Pharmaceutical Purified Water systems guarantees sub-ppm levels of salts.

Although these stable technologies require minimal maintenance, they must be protected from oxidising species that affect performance and lifespan. Removal of free and total chlorine in process lines prior to RO and EDI is essential. To achieve this, two traditional methods exist: Activated Carbon Filtration (ACF) and Sodium Meta-Bisulphite dosing (SMB). Although well proven, these methods demonstrate certain limitations, principally that they are prone to microbial contamination that increases the bio-burden on EDI and RO membranes, leads to increased cleaning frequency and creates higher operating costs.

To help explain how to overcome these issues, the webinar will outline how UV light can be used as a dechlorination technology, replacing the need for ACF and SMB. This helps to deliver optimum dechlorination performance without the problems associated with these traditional technologies. Tim McDougle will begin by looking at the need to remove chlorine, the current technologies used and the issues surrounding them. James Hadley will then provide an overview of UV light, how it dechlorinates, and the advantages it provides over alternative methods.

The webinar will begins at 3pm BST 23rd May 2017. Register here to learn how UV dechlorination can optimise your water treatment process.
