Again, a certified bestUV system for the Alps

alpsDutch manufacturer bestUV was selected to supply the latest Önorm-certified ultraviolet (UV) system for a touristic village in the Alps.

The purpose of the certified bestUV system is to protect the visitors and inhabitants against pathogens in the drinking water. 

The BetaLine certified UV system will replace an existing UV system which did no longer fulfill the demands of treating drinking water. Based on the experiences, the bestUV system will be equipped with fully automatic cleaning device to prevent fouling of the quartz sleeves and UV sensor.

The UV lamps are automatically adjusted in power based on water quantity and quality, resulting in a minimal usage of energy.

Ultraviolet light has an advantage over chemical treatment, such as chlorine, as UV does not formate chlorinated organic compounds.

BestUV system was selected because of the low energy consumption, compact size, robust construction of the UV reactor.

Two waterworks select BetaLine UV systems

ByglandsfjordDutch UV manufacturer bestUV is again selected to deliver Önorm validated BetaLine UV systems for two scandinavian communal drinking water plants. The drinking water is mechanical filtered surface water and origins from the lake. The two waterworks decided to replace some low-pressure (LP) UV systems, installed in the 80‘s, by ‘state-of-the-art’ bestUV systems.

BetaLine UV systems were introduced to the market after intense validation procedures at universities for Water hygiene, (Patho)physiology and Biophysics. They are approved by several international health institutes for use in disinfection of water for human consumption. 

Bygland_and_JordalsboeBetaLine is a compact UV system, equipped with unique high-efficient low-pressure UV lamps. They operate in automatic mode on the most economic lamp power due to bestUV’s intelligent power controlsystem. The bestUV system runs exactly on the power needed to fulfill minimum UV dose requirements, even when flow and surface waterquality change.

Compared to medium-pressure (MP) UV systems the BetaLine is saving a lot of energy and has thus the lowest carbon footprint, which fit into the ‘environmental phylosophy’ of the waterworks. 

The engineers selected bestUV systems for a couple of reasons:

  • lowest investment costs,
  • 15 years lifecycle costs calculation (LCC),
  • long lamp life, 3x more compared to medium-pressure UV lamps
  • easy installation and maintenance,
  • automatic lamppower controlsystem, resulting in minimum use of energy,
  • automatic cleaning device, included in Önorm validation tests,
  • proven reliability at many drinking water references.

Again bestUV systems are disinfecting drinking water for human consumption against lowest costs on a very environmental friendly way and thus preserve and protect the beautiful nature.

bestUV systems for cosmetics industry in Eastern-Europe

bestUV was again awarded for delivery of several bestUV systems for a cosmetics company in Eastern-Europe.

The bestUV systems, integrated in the water treatment loop, are used for the following purposes e.g.: 

  • disinfection
  • deozonation
  • dechlorination
  • TOC reduction

All applications require their own specific UV dose (mJ/cm2) to be effective. UV for the disinfection process is totally different from the other processes. For breakdown of ozone (O3), free chlorine (HOCl/OCl-) and Total Organic Carbons (TOC) a much higher UV dose is required compared to disinfection and in some cases different combinations of UV lamps and quartz sleeves are required.

Besides bestUV’s decades of application knowledge, a very important strength of bestUV is the possibility to customize the bestUV systems according to the endusers’ requirements. The bestUV systems follow the highest standards in cosmetics and pharmaceutics industries, such as, but not limited to:

  • hygienic tri-clamp connections,  
  • hygienic construction,
  • material certificates 3.1 acc to EN 10204:2004

For more information about bestUV’s innovative and customized UV systems, please contact the experts in ultraviolet light.

Hotel pool uses bestUV systems

From its succesful range AlfaLine UV, bestUV delivered UV systems for treatment of several children pools.

Treatment of children pools is both important and difficult. Important, because of the sensitivity of young children for chloramines (bounded chlorine) and difficult, because young children create high amounts of chloramines in swimming pools.

Based on many years of practical experiences and comparisons of many results, bestUV developed its own ‘Code of Design’ (CoD). The CoD combines several pool parameters and the use of bestUV’s own UV lamps. 

Besides low amounts of chloramines in water and air, the bestUV systems also provide lowest operational costs for the pool. 

For more information contact the experts in ultraviolet light.

bestUV awarded for delivery to Baltic State

Dutch manufacturer bestUV is again awarded to deliver ultraviolet (UV) systems for disinfection of drinking water to one of the Baltic States.

The bestUV systems are all equipped with high-efficient UV lamps and automatic cleaning mechanisms for prevention of fouling of the protective quartz sleeves and UV sensor.

The delivery is part of a waterproject financed by European Union funds for reconstruction of water and sewage systems.

The UV units will be installed in a pressure pumping station, supplying disinfected drinking water to small communities with total amount of abt. 20.000 inhibitants.

The local company already installed several bestUV systems and again selected the bestUV systems for reasons of proven reliability, effectiveness, easy maintenance and good price/quality ratio.

Young children enjoy healthy pool water and air

Dutch UV manufacturer bestUV again succesfully runs with several UV systems in a public swimming pool. The result is: improved, pleasant and healthy air without ‘chlorine smell’.

The bestUV systems have remarkably effects on the air in the indoor swimming pool. This is important as young children enjoy to play in paddling, toddlers and whirlpool.

The amount of bounded chlorine is below 0,20 ppm, meaning that the level of bounded chlorine follows the strict german regulations DIN 19643-1(5.3.16) of max. 0,20 ppm of combined chlorine.

It is very important for young children to prevent exposure to high amounts of chloramines, especially trichloramines (TCA). Many international reports confirm the health risks of exposure to trichloramines at young children.

The bestUV systems are equipped with special UV lamps. The lamps are unique, emit the specific wavelengths to breakdown a.o. trichloramine. 

Single wavelength, low-pressure (LP) UV lamps, are not used as the germicidal wavelength of 254nm, is not effective to breakdown trichloramine by direct photolysis.

It is obvious that young children, their parents and the staff feel very comfortable in the several pools treated by bestUV units. The result is a pleasant and above all healthy pool air where visitors want to stay and return.

For more information about the use of the special lamps in swimming pools, contact the experts in ultraviolet light.

New-built aquaparc uses bestUV units

Several bestUV systems were installed in one of the latest new-built aquaparcs in Europe. The new constructed aquaparc is officially opened in the begin of 2012.

Dutch manufacturer bestUV, leading in UV units for swimming pools, was selected by the contractors because of its wide range of references, proven effects and high quality products with lowest operational cost. 

In the new-built aquaparc the bestUV units are used in:

  • 25m pool
  • 50m Olympic swimming pool
  • toddlers pool
  • recreation pool
  • salt water pool
  • whirlpool

All pools are equipped with bestUV systems including specially developped bestUV lamps, UV sensor technology and cleaning device to prevent fouling of quartz sleeves. 

Salt water pool

Especially the UV unit for the ‘salt water pool’ is confirming again the innovative strength of bestUV. The salty pool water is highly corrosive to the material normally used in pool water. After many years of testing in comparable situations, bestUV is able to provide a high quality low-cost solution for UV pool units, resistant to highly corrosive warm salt water.

German DIN

The bestUV systems are following the new draft (May 2011) of the German DIN 19643-2:2011-05 chapter 4.5.5. The DIN allows the use of specific medium-pressure UV lamps only. 

Medium-pressure UV lamps for discharged waters

Ultraviolet (UV) light has become widely accepted as an alternative to chemical disinfection (e.g. chlorination) of water. Although it is believed that all UV lamps (LP and MP) act the same, there are reasons to assume that both lamp technologies act differently. These different effects are thoroughly studied in practise and in science. 

This document describes the background of different actions on micro-organisms by the two major lamp technologies:

  • low-pressure UV lamp (LP)
  • medium-pressure UV lamp (MP)

The document is very interesting, especially for applications where water is exposed to visible (sun)light ater UV-treatment, such as:

  • communal waste water (after discharging)
  • ship’s ballast water (after deballasting)

It is concluded that the broad-spectrum of wavelenghts, emitted by medium-pressure (MP) UV-lamps, result in multiple effects on the microbiological cell. These effects are especially of interest with regard to the theme of ‘photorepair after UV-treatment’. Photorepair can take place immediately after exposure to visible (sun)light. This is an issue when water is discharged into ‘open waters’ like river, lake and/or sea. The conclusion of the studies is that medium-pressure (MP) lamps are favoured to prevent repair of the UV-exposed cell.
