Microwave ultraviolet oxidation equipment for odor control

Product Overview

The Microwave UV Oxidation System is an advanced oxidation technology designed for industrial air pollution control, wastewater treatment, odor removal, and sterilization applications. The system combines microwave energy, electrodeless ultraviolet light, ozone generation, and photocatalytic oxidation to create multiple oxidation pathways for contaminant degradation.

Unlike conventional UV systems that rely on electrode-based lamps, microwave UV technology uses microwave energy to excite electrodeless lamps, producing stable ultraviolet radiation and ozone generation without electrode deterioration. This design reduces maintenance requirements and extends operating life in demanding industrial environments.

The technology is particularly suitable for the treatment of low to medium concentration organic pollutants, odor compounds, and difficult-to-degrade contaminants found in industrial exhaust gases and wastewater streams.

Advanced Oxidation Reactions

Ozone, ultraviolet energy, and optional catalysts generate highly reactive hydroxyl radicals capable of oxidizing complex organic compounds.

Final Conversion

Organic contaminants are converted into simpler compounds, primarily carbon dioxide, water vapor, and inorganic byproducts depending on the pollutant composition.

Industrial odor control FAQs

What is an industrial odor control system?

An industrial odor control system treats odor-causing compounds such as hydrogen sulfide, mercaptans and organic amines from industrial exhaust. Common technologies include microwave UV oxidation, low-temperature plasma, activated carbon and biofiltration; selection depends on the odor source, airflow and concentration.

How does MW-UV odor control work?

MW-UV odor control combines microwave-excited electrodeless UV lamps, ozone generation and photocatalytic oxidation. UV photolysis breaks odor molecule bonds, 185 nm UV converts oxygen to ozone, and hydroxyl radicals oxidize residual compounds into carbon dioxide and water.

Can MW-UV treat wastewater treatment plant odor?

Yes. MW-UV systems treat odor at wastewater treatment plants and sewage pump stations, including headworks, sludge handling and tank vents, where hydrogen sulfide and other odor compounds are common.

Can MW-UV handle sludge and biosolids odor?

Yes. MW-UV is used for sludge and biosolids odor control at wastewater and sludge handling facilities, oxidizing sulfide and organic odor compounds without the chemical handling of scrubbers.

What is sulfide odor control?

Sulfide odor control targets hydrogen sulfide (H2S) and sulfide compounds. UV/ozone oxidation converts sulfides into sulfate, removing the rotten-egg odor characteristic of wastewater and sewage environments.

What is odor control at waste transfer stations?

Waste transfer stations generate odor from organic waste and leachate. MW-UV systems are installed for odor control at these facilities; see our Haicheng municipal waste transfer station case for an example.

What is the difference between UV oxidation and photocatalytic oxidation?

UV oxidation uses ultraviolet photolysis and ozone. Photocatalytic oxidation adds a photocatalyst (such as titanium dioxide) that generates additional hydroxyl radicals. MW-UV equipment can combine both pathways for higher removal.

Using microwave UV for wastewater odor

Microwave UV equipment can form part of an odor control train for enclosed sewage and sludge sources. The review should cover airflow, odor components, H2S and ammonia peaks, humidity, mist, residence time, pretreatment and any downstream polishing stage.

A useful proposal defines the capture system and every treatment stage, not only the UV reactor. Start with the wastewater odor control system guide and compare the process with low-temperature plasma equipment where both routes are being considered.

MW-UV Odor Control for Wastewater and Organic Waste Sites

Microwave ultraviolet oxidation is suited to low-concentration, strong-odor air streams where rapid response, compact installation and simple source treatment are important. It is commonly evaluated for pump stations, waste transfer stations, livestock facilities, kitchen-waste rooms and sludge handling areas.

• Hydrogen sulfide, ammonia and mixed organic odors
• Intermittent or fluctuating odor loads
• Limited installation space and retrofit projects
• Source capture with modular fan and duct integration

Request an MW-UV odor-control proposal with odor sources, airflow and operating schedule.

Application in wastewater odor control

This equipment may be evaluated for captured air from wastewater treatment plants, pump stations, wet wells, sludge storage and dewatering areas. The water treatment process and the air treatment process have separate design duties.

Before selecting a unit, provide the source enclosure, normal and peak extraction flow, H₂S and ammonia data, humidity, temperature, operating hours and required outlet condition. High moisture, droplets and changing gas composition may require pretreatment or downstream polishing.

Review the wastewater odor control system guide for capture, comparison and quotation requirements. Final capacity and performance must be tied to the measured gas duty and agreed test method.
