Atlantium's pathogen-specific solutions, delivered by systems using medium-pressure UV, assure users of disinfection success.

UV light's germicidal effects on microorganisms
UV light's germicidal properties have been known to scientists for more than a century.  Invisible to the eye, UV light inactivates microorganisms in milliseconds by various modes of action: damaging DNA, RNA and enzymatic systems.  

The type of damage to microorganisms' DNA caused by low pressure lamps that deliver their UV dose at 254nm leads adjacent Thymine bases to bond with each other, making them incapable of reproduction.

Atlantium's wide spectrum medium pressure lamps however, deliver UV that causes DNA-protein crosslinks, enzyme inactivation, as well as actual DNA breakage. This damage is less subject to repair and thus, leads to more highly effective microbial inactivation.

Determining the correct UV dose for target microorganisms
Accurate determination of UV dose requirements and subsequent reliable delivery of the required dose ultimately establishes the real disinfection results.  

Using the highest professional standards - methodologies recommended by the US Environmental Protection Agency - Atlantium can test field water samples to precisely determine dose requirements. 

The EPA method utilizes a Collimated Beam Apparatus (CBA), a testing instrument designed to accurately measure the UV dose delivered to a microbial suspension and understand the system's ability to inactivate the microorganism. Following measurement, the same type of water and microbes used in the CBA are tested in the actual Hydro-Optic Disinfection system. All Atlantium's Hydro-Optic Disinfection models have been tested under a wide array of water conditions, UV doses and test microorganisms to make sure it adjusts to fluctuating conditions of water flow and UV transmissivity.

Diagnosing and meeting customer needs: A pathogen-specific solution
Atlantium maintains its own Microbiology division and laboratory which provides full support to Atlantium personnel. Once a disinfection solution that accurately corresponds to site conditions and customer requirements has been identified the prescribed system is calibrated to deliver the determined UV dose to inactivate the target microorganisms under the site-specific conditions. 

The Microbiology division also performs special consulting services and in-depth site analysis and diagnosis where there is a need to troubleshoot microbial and water anomalies. Customer research programs have included viruses such as WSS and IVN, bacteria such as TAB, Bacilli Sporoform and Deinococcus radioduranda, molds such as Aspergillus niger and others, and yeasts such as Saprolegnia and others - that may be found in industrial, municipal, aquaculture and agricultural settings.

The Microbiology division is involved in multi-national studies on system performance against viruses and bio-films. The division's involvement in cutting edge research means that Atlantium customers are alerted to the latest developments in UV practices which can protect their sites from existing and new threats.
