Proactive monitoring and detection of pollution sources

Understanding critical sources and parameters for optimal management of your processes and associated risks

Your wastewater and industrial water treatment sites are essential in safeguarding the environment by removing contaminants from effluents before they are released into nature. However, these facilities can also be sources of atmospheric pollution and other nuisances. Emissions of gases and particles from your processes can significantly affect local air quality and public health. Moreover, managing odor nuisances presents additional challenges that require advanced technological solutions to ensure the safety of your employees, protect surrounding communities, and maintain the integrity of your infrastructure.

Ellona’s advanced technologies offer real-time monitoring of envi

ronmental emissions, including odors and gases. This continuous surveillance enhances your ability to proactively detect and manage pollution sources, minimizing risks to employee safety and improving the quality of life for nearby communities.

Our extensive expertise in source identification, precise concentration measurement, dispersion plume analysis, and effective remediation strategy implementation is crucial for addressing these challenges while safeguarding your infrastructure. With Ellona, you gain a comprehensive solution for understanding and managing pollution sources at your facilities, ensuring a safe work environment, enhanced community protection, and the durability of your operations.

A one-of-a-kind approach for your operations

Analyses en temps réel
01

Real-time multi-variate analysis.

Thanks to our environmental intelligence platform, Ellona transforms raw data into actionable insights with unmatched precision. By relying on data updated every 10 seconds, we continuously analyze a multitude of variables. Our specialty lies in our ability to handle multi-variate data, enabling a comprehensive and in-depth understanding of the phenomena analyzed, making the actions taken more effective and impactful for businesses and communities.

02

Identification and triangulation of footprints and sources.

Ellona’s artificial intelligence algorithms and databases go beyond mere quantification. We excel in the precise identification of footprints and sources, whether surface-level or channelized. Data triangulation is at the core of our approach, allowing us to cross-reference information and accurately locate sources.

03

Dynamic emission modeling.

Ellona provides advanced dispersion software that integrates real-time meteorological data. This dynamic model simulates and visualizes the impact of a site’s emissions on its immediate environment, offering tailored preventive and corrective solutions.

04

Smart alerts and customized notifications.

Our platform allows you to set up different types of real-time alerts tailored to each user’s specific needs. Additionally, the automatic generation of smart reports ensures optimal responsiveness to any critical situation.

05

Automatic triggering of remediation systems.

This feature allows for the automation of triggering third-party systems (such as sampling, misting, ventilation, etc.) through precise management of ON/OFF devices and 4-20 mA inputs, or via the API. This automation ensures a rapid and appropriate response in the event of a detected incident.

06

Integration of human perceptions via QR codes.

Ellona enhances its analyses by integrating human perceptions collected via QR codes. These subjective data are then correlated in real-time with the technical data collected by our systems, providing a comprehensive and nuanced view of the situations for even more precise interventions.

Multiple emission sources we address

The integration of Ellona’s advanced technologies allows for real-time monitoring of environmental emissions, including odors and gases. This continuous surveillance enhances the ability to proactively detect and manage pollution sources. Beyond gases, odor-related issues present a significant challenge. Ellona’s in-depth expertise in identifying sources, accurately measuring concentrations, analyzing dispersion plumes, and implementing effective remediation strategies is essential for addressing these nuisances.

The main categories of atmospheric emissions associated with wastewater treatment facilities, both domestic and industrial, are:

  • Emissions from primary and secondary sedimentation tanks (also known as clarifiers or settling tanks): Volatile organic compounds (VOCs), greenhouse gases such as methane (CH₄).
  • Emissions from anaerobic digestion units: Significant sources of odors and biogas (CH₄, NH₃, CO₂, H₂S, SO₂) if the capture and combustion systems are deficient.
  • Emissions from biological filters: Odors, fine particulate matter in suspension.
  • Emissions from pumping stations: Odors and fine particulate matter.
  • Emissions from sludge treatment systems (incineration or composting): Fine particulate matter, heavy metals, gases (CO₂, CH₄, NOₓ, VOCs, NH₃, SO₂, H₂S)

Capteur WT1 Lite
Capteur POD2
Plateforme EllonaSoft

Ellona provides advanced solutions for wastewater treatment, delivering real-time monitoring tailored to the complex needs of the sector, particularly for odors, gases, and particulate matter.

The WT1 Pro is engineered to monitor emissions in industrial environments, along site perimeters (fencelines), and at the source. It offers precise identification and quantification of odors in compliance with EN 13725 and ASTM 679 standards.

For indoor environments such as offices and reception areas, the POD2 ensures effective emission monitoring. The WT1 Lite is perfect for peripheral sites, providing a cost-effective solution for less demanding applications.

Our comprehensive suite of devices—including the WT1 Pro, WT1 Lite, POD2, and the EllonaSoft platform—ensures thorough and accurate monitoring of pollution sources in wastewater treatment plants, treatment facilities, and collection networks.
