Operational air quality monitoring at municipal wastewater treatment facilities in 7 days

Summary

This case study describes how Sokol Meteo deployed an operational air quality monitoring system at a municipal wastewater treatment facility in just 7 days. The solution combined Sokol-GA gas analyzers with the Sokol-M1 weather station to provide verified, measurement-based data for the customer and relevant authorities.

Project type: Environmental monitoring
Format: Urgent deployment
Equipment: Sokol-GA gas analyzers and Sokol-M1 weather station
Implementation time: 1 week instead of the standard timeline of approximately 1 month
Client: Municipal water utility

Context: A Situation Under Public and Regulatory Scrutiny

Sokol Meteo received an urgent request related to a growing number of public complaints about ambient air quality in an urban area.

Further decision-making required more than subjective odor assessments. The customer needed measurement-based data: which substances were present in the air, at what concentrations, and how meteorological conditions affected their dispersion.

One of the sites where operational monitoring had to be organized was a municipal wastewater treatment facility.

The Challenge

Given the compressed implementation timeline, the project required the team to:

provide operational monitoring of the gas composition of ambient air directly near potential impact sources;
record the composition and concentration of substances;
analyze the situation in near real time;
take meteorological conditions, including wind direction, into account when interpreting the data;
ensure that the measurements could be used in official reporting and regulatory work.

The key limitation was urgency: the system had to be deployed within one week instead of the standard one-month timeline.

Project Complexity

A municipal wastewater treatment facility is a complex infrastructure environment with a high concentration of volatile substances.

Additional factors included:

areas with increased gas formation and evaporation;
the need to place instruments not only along the perimeter, but also directly near potential sources of increased gas generation;
challenging and potentially unsafe conditions for the installation team;
mandatory metrological verification of the instruments to support the official use of measurement data.

Incorrect instrument placement or any delay in commissioning could have resulted in an incomplete picture of the situation and prolonged the overall analysis.

The Solution

Sokol-GA gas analyzers were selected for the project. These measuring instruments are designed for ambient air monitoring in industrial and urban environments.

As part of the project, the team:

quickly prepared a set of 7 instruments;
performed accelerated configuration and adaptation of the equipment for the specific site conditions;
arranged mandatory metrological verification within a compressed timeline;
installed the devices at key technological units, in areas with the highest probability of emission formation;
integrated the data with the Sokol-M1 weather station to account for wind conditions and the dispersion of volatile substances.

The Sokol-M1 weather station also served as a controller: it transmitted data via GSM to enable remote system operation. If communication was temporarily lost, the data were stored in the weather station’s internal memory, ensuring that no information was lost and could be uploaded later.

Why Sokol-GA

In this project, not only the technical characteristics of the instruments mattered, but also their readiness for rapid deployment. Sokol-GA was well suited to the task for several reasons:

The instruments can undergo official metrological verification, allowing the data to be used in reporting and regulatory work.
The equipment is designed to operate in challenging weather and field conditions.
The gas analyzers can be installed close to potential gas formation sources without complex engineering solutions.
The instruments were available for rapid dispatch, which helped reduce delivery time.
Upon the customer’s request, the vendor can provide installation supervision or fully manage equipment installation.

Implementation: One Week Instead of One Month

The project was completed within an exceptionally short timeframe. After receiving the urgent request and agreeing on the technical requirements, the team prepared the equipment, arranged accelerated metrological verification, organized delivery and on-site installation, and checked the correctness and stability of data transmission.

The full cycle, from the initial request to the launch of the monitoring system, took 7 days.

Practical Results

After the system was launched, the customer and relevant authorities gained access to factual data on air conditions at the facility.

The installation of gas analyzers made it possible to:

monitor the actual air composition instead of relying only on subjective perceptions;
compare air quality indicators with the facility’s technological operating modes;
take wind direction into account and assess the dispersion area;
respond quickly to possible deviations.

The monitoring system became a practical tool for analyzing the situation at the site. In addition, the solution architecture was designed with scalability in mind from the outset: the number of monitoring points and the system’s functionality can be expanded without rebuilding the entire infrastructure.

Project Outcomes

The monitoring system was launched in 7 days.
7 Sokol-GA gas analyzers were installed at the site.
The instruments were placed near key technological units.
Data are transmitted remotely via the Sokol-M1 weather station.
In case of temporary communication loss, information is stored in the internal memory.
Thanks to metrological verification, the data can be used in official reporting and regulatory work.

Conclusion

Within one week, a monitoring system was deployed at the facility to record air composition near potential gas formation sources and take meteorological conditions, including wind direction, into account.

This made it possible to move from assumptions to factual data. The customer and relevant authorities received a tool for continuous control of the situation and measurement-based decision-making.
