Aquatic invasive species such as zebra and quagga mussels can be a nuisance to the power generation industry. For facilities that use surface water, where these mussels are prevalent, this nuisance can be quite costly. The biggest area of concern is where the adhesion of mussels to the intake water lines causes restricted flow, reduces

There are a several variables that need to be considered when sizing a new UV disinfection system. One of the most obvious variables is the flow rate of the water through the system. However, there is more to a flow rate than just determining a `m³/hr’ value and plugging that number into a sizing equation.

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

By Dan Shaver There are a several variables that need to be considered when sizing a new UV disinfection system. One of the most obvious variables is the flow rate of the water through the system. However, there is more to a flow rate than just determining a `gallons per minute’ value and plugging that

by Brian Grochowski Food and beverage companies are increasingly specifying validated UV disinfection systems for use within their manufacturing processes. This shift in policy is being seen in many dairies, bottled water facilities and carbonated beverage operations. The trend is driven in many cases by corporate influence and guidelines that aim to ensure consistency and

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 platform was created taking customer feedback into consideration, to deliver

UV light, especially in the wavelength range of 200-280 nm, is well documented to provide excellent water disinfection. So, with the technology seen to be so effective, why might it be important to have a UV system validated? As you might expect, most of the studies on UV disinfection have focused on its antimicrobial effectiveness

When a UV disinfection system is recommended to a customer by a manufacturer, there are several different methods that can be used to provide the appropriate sizing. Correct sizing ultimately guarantees the overall performance of the system in terms of an expected log reduction of bacteria, virus or specific target organisms. While all sizing algorithms

Moisture and particulate can greatly affect the lifespan of a control cabinet. In addition, exposure to challenging environmental conditions can affect the function and longevity of the panel. The control cabinet supplied with a UV disinfection system is no different, and in many cases, its exposure to harmful contaminants is exacerbated by the harsh environments

The global UV municipal market value in 2015 was US $308 million and is predicted to grow 16% over the next five years, while the industrial UV market was worth US$206 million in 2015 and is forecast to grow to $360 million by 2020 an 11.8% increase.
