UV Disinfection

UV Disinfection of Wastewater & Reuse Water

UV disinfection is popular around the globe for wastewater treatment and water reuse treatment largely due to the fact that, unlike chlorine, it doesn't increase effluent toxicity. Pressure from Governments and environmentalists to eliminate unwanted chemicals from the ecosystem, whilst providing pathogen free water, is also driving interest in UV disinfection  for wastewater treatment. This interest is leading to many wastewater and water reuse plants being converted from chlorine to UV disinfection. Water re-use is also becoming important, with purified wastewater disinfected by UV disinfection systems increasingly being used for irrigation. Berson is the leader in wastewater UV and reuse water treatment.

Advantages Of UV Disinfection of Wastewater & Reuse Water

UV wastewater systems are a well established method of wastewater treatment  and reuse water treatment safeguarding public health and protecting wildlife. There are different types of wastewater, such as municipal sewage or industrial effluent, and these different wastewaters all have their own types of microbiological environment, microbiological counts, levels of suspended solids, UV transmission rates and temperatures. Depending on whether the effluent is to be discharged into rivers, lakes and seas or re-used for applications such as irrigation, the required microbiological counts are usually specified by local regulations.

The most common method of reuse water treatment has long been chlorination. Despite chlorine’s impressive track record, concerns regarding disinfection by-products (DBPs) and, more recently, disinfection performance with respect to pathogen inactivation, are driving the conversion from chlorine disinfection to other disinfection methods such as UV disinfection, which does not produce any DBPs.

Closed vessel UV wastewater disinfection systems are easy to install within existing pipework, so there is minimal disruption to plant operation. Day to day operation is simple and only minor maintenance is needed. The only regular requirement is changing the UV lamps and wiper rings once a year, a straightforward operation that can be carried out by on-site personnel.

UV wastewater systems are also validated to much higher doses than drinking water systems, according to protocols established by the National Water Research Institute (NWRI) in the USA. Drinking water type product validation, with the accompanying rigour, is emerging as the dominant method of assessing suitability for these critical applications. The ability to prevent photo repair is also key. 

Thousands of wastewater sites globally use UV systems for wastewater treatment. Berson UV wastewater systems are environmentally friendly with:
• Lower operational costs
• CFD design
• Bioassay validation
• Lowest number of lamps
• Smallest footprint and lowest headloss
• Highest medium pressure UV Lamp life with automatic wiping 

Berson UV was the first supplier in the world of closed pipe UV systems for wastewater treatment. Berson also invented the bersonInLine® concept, with all Berson InLine UV disinfection systems having the highest kill rate efficiency compared with power consumption. Berson UV also developed the Berson MultiWave® medium pressure lamp, which has a very high power consumption efficiency and which ensures no microbial no photo repair of UV-damaged DNA.

All Berson InLine UV systems are equipped with Berson MultiWave® lamps and have an optimised chamber design using CFD (Computational Fluid Dynamics) with low head loss. They are all very compact with a small footprint, making them easy to retrofit. Electronic ballasts (stepless power supplies) enable the units to compensate for any unforeseen lower transmissions or increase in flow rates and use up to 20% less power than other energy control methods. Berson automatic wipers keep the lamps clear of fouling and the advanced UVtronic control module provides data logging and is fully programmable.

Finally, the design of the Berson chambers forces the wastewater to pass perpendicularly to the UV lamps, meaning there are no 'blind spots'.

The temperature of wastewater has a significant influence on the choice of UV lamp. Medium pressure UV lamps, like the Berson MultiWave range, are not influenced by water temperature, while low pressure UV lamps have an optimum operating temperature of around 20°C, with a change in water temperature of only 5°C significantly influencing the lamp's performance. Medium pressure lamps should therefore always be used if large temperature fluctuations are expected.

Berson

Berson UV Disinfection systems are used around the globe in drinking water, wastewater and water reuse treatment plants. Berson's UV systems are validated to the most stringent third party approvals, including DVGW, USEPA, JWRC, NWRI and NSF.

Berson InLine UV System

Berson InLine UV Systems are in use worldwide and have been the best in UV for over 40 years. Berson have a strong focus on innovation, improving disinfection performance, system efficiency, maintenance friendliness and low total cost of ownership.

Berson is the first manufacturer to produce an 'in-line' UV unit with medium pressure lamps. The berson InLine® uses Berson MultiWave® lamps combining a wide spectrum of useful UV wavelengths with a very high energy output. This combination causes total and permanent deactivation of micro-organisms, avoiding photoreactivation.
The compact size and high energy output of the Berson MultiWave® lamps reduces the size of the irradiation chamber and quantity of lamps drastically. The "in-line" construction results in a very low headloss and small foot-print compared to conventional medium- and low-pressure UV systems.
Conventional low-pressure lamps only damage the DNA as a result of absorption of the monochromatic (254nm) wavelength. However, in general, microorganisms use a repair mechanism to get rid of UV damaged DNA.

Using berson MultiWave® lamps, with their broad band polychromatic spectrum, not only DNA is damaged but also other biomolecules are (in)direct influenced. This results in a different repair tendency compared to monochromatic low-pressure UV lamps.
