Municipal Wastewater

Treatment of municipal wastewater is critical to preserving our environment and meeting regulatory requirements. Removing solids, nutrients and inactivating pathogens can all be accomplished using De Nora technologies.

Treatment of municipal wastewater is critical to protecting both the environment as well as human health.  Excessive nutrients in the water can cause problems with algae growth and oxygen deprivation in the receiving water bodies.  In addition, human pathogens need to be neutralized in order to protect the health of those living downstream.  Another emerging concern is trace organic contaminants, such as biopersistent pharmaceuticals which can impact organisms living in the receiving waters.

From traditional treatment options like deep bed filtration and gas chlorine disinfection* systems to advanced oxidation technologies that remove micropollutants, De Nora is committed to innovation in wastewater treatment. By combining technologies for advanced treatment, improving products for water and energy efficiency, and developing more intuitive and intelligent solutions, we are always improving the treatment process for use – and reuse – of our limited water supply.

Advanced Oxidation

Advanced Oxidation Processes produce highly energetic free radicals that can destroy a wide variety of difficult to remove organic contaminants by converting them to carbon dioxide and water

Biological Filtration

Biological filtration is an effect method of using facultative bacteria supported by filter media to remove organic compounds and achieve nitrification and denitrification.  Remove soluble and particulate contaminants in a single step, simplifying your plant operations while increasing removal performance.

Disinfection and Oxidation

Depending on your application, you may need additional oxidation to reduce contaminants prior to discharge. Alternatively, you may need to disinfect your waste stream prior to discharge or reuse. No matter your specific need, De Nora Water Technologies has the technology to meet your requirements. As experts in everything from chlorine (gas or generated hypochlorite), to more advanced technologies like ozone and UV, we can help choose the right technology for your application.

Filtration

Used alone for some irrigation applications or as pretreatment to additional processes, tertiary filtration of wastewater is a key process step used to enhance water quality and ensure the wastewater is treated adequately for reuse.

Instrumentation

Monitoring chlorine residual and other parameters is critical for process control, monitoring and reporting.
