UV Disinfection Wastewater: Industrial and Municipal Applications

UV disinfection systems are widely deployed across industrial and municipal wastewater applications.
These systems neutralise pathogens without chemicals, making them ideal for facilities prioritising safety, sustainability, and compliance.

Industrial applications include food and beverage processing, pharmaceuticals, and manufacturing plants—anywhere hygiene and discharge control are critical.
Municipal deployments range from large-scale urban systems to smaller regional plants, where UV helps meet stringent environmental regulations and maintain public trust in water safety.

UV Application in the Water Reclamation Plant

Delivers a sustainable design while not compromising on quality or performance

UV systems offer a sustainable design without compromising on quality or performance.
As urbanisation and water stress rise, the demand for tertiary wastewater disinfection grows—especially where discharge affects sensitive ecosystems.


UV disinfection is now the preferred alternative to chlorination for safe, chemical-free wastewater treatment.


In modern water reclamation plants, UV disinfection is typically applied as the final barrier before discharge.


It inactivates a broad spectrum of microorganisms without introducing residuals, making it safe for use near aquatic life, agriculture, or groundwater recharge zones.


Operators value UV for its ease of automation, consistent performance, and lack of harmful by-products—key concerns in sustainable infrastructure.

    UV Disinfection for Wastewater FAQ’s

    Find answers to your key questions below

    What is UV wastewater disinfection and how does it work?

    UV-C light (specifically the 254 nm germicidal band) penetrates microorganisms and scrambles their DNA or RNA so they can’t reproduce. Because nothing is added, the treated effluent is unchanged except for deactivating pathogens.

    Why choose UV instead of chlorine or other chemicals?

    Nuvonic’s Open Channel delivers “energy-efficient, chemical-free, open-channel disinfection” — so there are no hazardous chemicals to store, no toxic disinfection-by-products such as trihalomethanes, and no need for de-chlorination before discharge.

    What makes Nuvonic’s Open Channel system different?

    OpenLine uses low-pressure, high-output amalgam lamps inside an open-channel frame. This combination keeps power demand low while still hitting high log-reduction targets, and it can be dropped straight into a concrete or steel channel with minimal head-loss.

    Which pathogens does the system inactivate?

    At a properly validated dose, UV achieves ≥ 4-log reductions of common bacteria such as E. coli, viruses, and chlorine-resistant protozoa (Cryptosporidium, Giardia).

    Does UV leave any chemical residuals in the effluent?

    No. UV treatment is purely physical, so it produces no taste- or odour-forming compounds and no regulated disinfection by-products.

    How energy-efficient is Open Channel?

    The amalgam lamps convert a high share of input power to germicidal light, and the channel design avoids extra pumping head.OpenLine is an  “energy-efficient” alternative to medium-pressure UV or chlorination plus de-chlorination.

    Can OpenLine be expanded for future flow increases?

    Yes. Additional lamp modules can be clipped into the existing rack, so plants can buy only the UV power they need today and add more capacity later.

    Is UV accepted by regulators for final effluent disinfection?

    Yes. UV is recognised by the US EPA and the EU Urban Waste Water Treatment Directive; most national guidelines list properly sized and validated UV as an approved wastewater disinfection technology.

    Is the system suitable for water-reuse applications?

    OpenLine can be sized for the higher doses (typically around 100 mJ cm-²) required by Title 22, WHO and similar reuse standards, providing chemical-free disinfection that won’t foul membranes downstream.

    Can the plant be monitored remotely?

    With the optional UV Connect module, Nuvonic offers a secure VPN link so engineers “see what you’re seeing on the control panel” and help troubleshoot in real time.
