Water Treatment Disinfection


 De Nora Water Technologies


Ultraviolet disinfection (UV) has been known for over 100 years as an effective method for inactivating waterborne pathogens and viruses.

As an alternative or supplement to traditional chemical disinfectants, an ultraviolet disinfection system offers a number of operating advantages. UV disinfection systems are safe and easy to operate.

In addition, the use of UV does not inject any taste or odor into the processed water, nor does it produce any undesirable by-products. UV disinfection systems feature a small footprint that is readily adaptable to fit into an existing treatment facility.

De Nora Water Technologies Services offers the UltraDynamics® and MicroDynamics® ultraviolet disinfection systems for use in wastewater treatment applications.

NeoTech Aqua Solutions

UV treatment is the most economical and effective way to protect water from biological and chemical contamination. As a well proven technology which has been applied for a long time, UV is the most adequate technique treating water in every step of the water cycle in nature, which includes underground and reservoir water through intake to river and ocean. UV is used in diverse applications such as drinking water, municipal and industrial wastewater, remediation of underground water, etc.

Neotech offers medium pressure UV systems that offer the following advantages:

  • Treatment systems that use up to 90% less energy than comparable equipment.
  • A foot print that is roughly 1/3 the size of competing systems.
  • Systems that use only one or two lamps, reducing maintenance time & cost.
  • A control box that can operate up to four UV systems independently, simplifying control and monitoring in applications with multiple UV systems.
  • All systems operate on 120 V or 240 V single phase power.


Waste water treatment

Increased attention to environmental protection may cause increasing use of UV disinfection systems instead of chlorination in more than 70% of waste water treatment plants in domestic market, as UV treatment does not produce DBPs (disinfection by-products) at all. Now various facilities from small automated village sewage treatment plants to large ones apply UV treatment systems, and the application has also diversified, which could mean UV treatment is generally approved as the effective and cost-efficient way of waste water disinfection.

Drinking water

In order to destruct pathogenic microorganisms which exist even after several steps of treatment processes, UV treatment has been suggested as the solution instead of conventional treatments that have their own limits such as insufficient treatment, cost burden, environmental pollution, deterioration of water quality or odor.

UV does not cause odor or DBPs (disinfection by-products) and effectively inactivates several pathogens like Cryptosporidium, Giardia which are highly tolerant to chlorination. UV is used worldwide in millions of drinking water treatment plant as it guarantees stable performance, can minimize chlorine input, is easy to operate, and is not affected by water temperature or pH value.
