  • How is the Asia Pacific Food & Beverage market taking to UV water treatment technology?

    The Asia Pacific (AP) region (outside of China and India) includes some of the fastest growing economies in the world. With rising incomes and continued population growth, demand for food and beverage products continues to rise. Coinciding with an increase in demand is a rise in manufacturing standards and quality levels.

  • China food and beverage industry is recognising the benefits of UV solutions

    The market for ultraviolet (UV) treatment equipment in the Asia Pacific food and beverage industry is both lucrative and fast-growing. It was worth USD 15 million in 2015, and that figure is predicted to have increased by 12.5% by 2020. This growth is mainly driven by increased manufacturing activity in the region, especially in China.

  • What is UVEO technology?

    By Gunvinder Bhogal – Global Marketing Manager (Aquionics, Berson, Hanovia) Continuing from my last blog on new water treatment technology such as ultraviolet light (UV) being used for dechlorination to replace activated carbon filtration (ACF), I will now focus on Hanovia UV systems that are powered using Ultraviolet Energy Optimised (UVEO) science. The UVEO technology … Continue reading “What is UVEO technology?”

  • Application-optimised low-pressure UV disinfection system simplifies water treatment and reduces lifecycle costs

    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.
