GENAQ: Pure water thanks to its exhaustive treatment
GENAQ atmospheric water generators take in ambient air, filter it and extract its moisture. Once the water is extracted by condensation, it is specially treated to obtain the highest quality water at the lowest energy cost. One of the main characteristics that make GENAQ’s atmospheric water generators superior is the quality of the water generated. Equally important is generating ...

Potential Repair of Escherichia coli DNA following Exposure to UV Radiation from Both Medium- and Low-Pressure UV Sources Used in Drinking Water Treatment
The increased use of UV radiation as a drinking water treatment technology has instigated studies of the repair potential of microorganisms following treatment. This study challenged the repair potential of an optimally grown nonpathogenic laboratory strain of Escherichia coli after UV radiation from low- and mediumpressure lamps. Samples were irradiated with doses of 5, 8, and 10 mJ/cm2 from a ...

Inactivation of human adenovirus by sequential disinfection with an alternative UV technology and free chlorine
There has been growing concern over human exposure to adenoviruses through drinking water due to the extreme resistance of human adenoviruses to the traditional UV technology (low-pressure (LP) UV). As an effort to develop an effective treatment strategy against human adenoviruses in drinking water, we determined the effectiveness of sequential disinfection with an alternative UV technology ...

How do we generate water at GENAQ?
The operation of GENAQ atmospheric water generators is very simple: they exactly replicate the process of rain. To do this, they take air from outside, filter it and extract its humidity. Once water is condensed, it is treated to obtain the highest water quality at the lowest energy cost. Do you want to learn more about how they work? One of our technology specialists, Álvaro Reymundo, ...

The effect of chlorine and combined chlorine/UV treatment on coliphages in drinking water disinfection
Chlorine disinfection is a globally used method to ensure the safety of drinking water. However, it has not always been successful against viruses and, therefore, it is important to find new methods to disinfect water. Seventeen different coliphages were isolated from the treated municipal wastewater. These coliphages and MS2 were treated with different dosages of chlorine in drinking water, ...

The biological safety of distribution systems following UV disinfection in rural areas in Beijing, China
In rural areas, UV disinfection has a great potential for drinking water treatment because of the ability to achieve target disinfection levels and the ease of operation and maintenance; however, UV disinfection provides no disinfection residual to the water distribution system. This study examines the biological safety of rural water distribution systems following UV disinfection. The results ...

Effect of granular activated carbon type and age on quenching H2O2 residuals after UV/H2O2 drinking water treatment
Granular activated carbon (GAC) can be used to quench residual hydrogen peroxide (H2O2) after ultraviolet (UV)-H2O2 advanced oxidation processes in drinking water treatment. Bench- and pilot-scale studies examined the possible loss of GAC reactivity due to continuous exposure to natural water from a water treatment plant in both the presence and absence of H2O2. Six common types of GAC were ...

Removal and degradation of glyphosate in water treatment: a review
Glyphosate is a broad spectrum, non-selective herbicide, widely used for the post-emergence control of annual and perennial weeds in a variety of applications. Although of low toxicity, its presence in drinking water is undesirable and can cause drinking water compliance failure in the EU if found at concentrations >0.1 μg L−1. Treatment methods such as ozonation and ...

HOW TO ASSESS THE EFFICACY OF UV DISINFECTION USING ATP TESTING?
UV disinfectionHow does it work? Nowadays, UV disinfection is commonly used for drinking water treatment. UV radiations alter nucleic acids (DNA and RNA) of most cells such as bacteria, viruses or protozoans. They damage the genetic material of microorganisms preventing them from replicating or ensuring part of their metabolic functions. UV radiations inactivate microorganisms. ...
