Can one system handle both disinfection and chloramine/chlorine reduction?
Yes. HOD UV reactors can perform both tasks, though chloramine/chlorine reduction requires higher doses (hundreds of mJ/cm² versus tens for microbes)
Why use HOD UV instead of sodium bisulfite or activated carbon?
HOD UV allows to avoid chemical handling, reduces waste, reacts instantly, results in superior disinfection performance and protects downstream membranes without generating residuals or needing regeneration.
Where is UV for chloramine/chlorine reduction used?
RO membrane protection, as well as chlorine removal before sensitive equipment such as EDI, resins etc. In industrial and municipal systems, food & beverage, pharma & microelectronics water polishing. Aquatic facilities (to reduce trichloramine odor and irritation), e.g swimming pools.
In a wastewater plant that treats only municipal wastewater, is the operation cost competitive?
HOD UV technology typically offers highly competitive operational costs, especially when compared to chemical-based disinfection or conventional UV systems. A detailed cost-benefit analysis for specific municipal plants requires additional information about flow rates and specific treatment
When organic load is very high and regulations require treatment, how do you ensure effectiveness?
HOD UV technology can be combined with Advanced Oxidation Processes (AOP) to manage high organic loads effectively. This combination ensures the degradation and removal of complex organic compounds, maintaining compliance with stringent regulatory standards.
For disinfecting drinking water, is it possible to completely replace chlorine with this HOD UV system?
HOD UV technology can significantly reduce or, in certain regulatory environments, completely replace chlorine for primary disinfection. However, regulatory standards in many regions, including Mexico, often require residual chlorine presence in distribution networks to maintain microbiological safety post-treatment.
Based on your experience with Advanced Oxidation, what contaminants can you remove?
Advanced Oxidation Processes (AOP) effectively remove challenging contaminants such as: Pharmaceutical residues Personal care products Endocrine disruptors Certain pesticides Taste and odor-causing compounds Specific persistent organic pollutants For contaminants like PFAS, Atlantium is actively developing and applying solutions demonstrating significant removal through ARP.
Which Viral Indicators Are Validated with Atlantium HOD UV?
Our systems have been validated using adenovirus, considered the most UV-resistant virus found in drinking water, achieving 4-log or greater reductions. HOD UV technology also effectively inactivates protozoa such as Giardia and Cryptosporidium, providing broad-spectrum microbiological safety.
Can Atlantium Systems Provide Uniform Radiation at High Flow Rates?
Absolutely. Atlantium's patented Total Internal Reflection (TIR) technology ensures uniform UV radiation, even for high flows exceeding 600 liters per second. Typically, systems are configured with multiple lamps to guarantee no shadow zones, delivering consistent and reliable disinfection across all water volumes.
Are There Residual Chemicals Post-UV Treatment?
No. UV treatment with Atlantium technology provides instant physical disinfection without any residual chemicals, unlike chlorine-based treatments. However, if incoming water already contains chlorine, Atlantium’s advanced HOD UV technology can help adjust doses to effectively minimize or eliminate chlorine residuals, promoting sustainable and safe water practices.
