Air Quality & Environmental Solutions
From Air Quality Assessment to Monitoring and Practical Treatment.
Air quality challenges can arise in indoor environments, public spaces, and industrial operations.
B&G works with IAQ specialists to support indoor air quality assessments, testing, and ventilation reviews. We also provide environmental monitoring, smart air filtration, and gas-treatment solutions.
By combining technical expertise, sensing technologies, and engineering capabilities, we help clients identify air quality problems and implement suitable improvements.
Environmental Odour Monitoring
Continuous Gas Monitoring & Early Warning Through Spectral Sensing
Industrial emissions and environmental odours can change over time, making continuous monitoring valuable for detecting abnormal conditions.
Spectral electronic nose technology enables ongoing gas-pattern monitoring, anomaly detection, and early-warning applications.
How It Works
An optical spectral sensing system measures absorption signal changes across multiple wavelengths to establish the typical response pattern of an environment. This baseline provides a reference for continuous monitoring.
Incoming measurements are compared with the baseline to detect abnormal changes, including sharp signal excursions. These deviations can trigger early warnings and highlight events for investigation.
Response patterns across multiple wavelengths are compared with reference patterns calibrated using standard pollutants to indicate likely pollutant identities. The combined pattern supports interpretation of an event and follow-up investigation of potential sources.
Application Areas
- Industrial emission and odour monitoring
- Environmental surveillance
- Abnormal gas-pattern detection
- Odour complaint investigation and source-tracing support
Smart Air Filtration Systems
Intelligent Air Purification for Public and Outdoor Environments.
Air pollution in public spaces, roadside environments, and transport facilities presents challenges involving particulate matter, odours, and airborne contaminants.
B&G provides modular, multi-stage air filtration solutions combining particulate filtration, photocatalytic treatment, and gas adsorption technologies.
How It Works
The system draws polluted air through multiple treatment stages:
- Pre-Filtration — Captures larger airborne particles.
- Particulate Filtration — Removes fine particulate matter using an electrostatic or PM filtration module.
- Photocatalytic Treatment (PCO) — Uses UV-assisted photocatalytic oxidation to support the treatment of suitable airborne contaminants.
- Gas Adsorption — Targets selected residual gases and odour-related compounds.
- Airflow Management — Directs treated air through the system outlet.
Where integrated with suitable air quality sensors, the system can automatically activate or adjust operation according to predefined monitoring thresholds.
Application Areas
- Roadside air pollution control
- Public parks and outdoor spaces
- Transport hubs and bus stops
- Industrial and commercial environments
Process Intensification & Treatment Solutions
High-Gravity Technology for Gas Treatment and Industrial Processing
Industrial processes often require efficient gas–liquid contact, separation, or treatment. High-gravity technology offers a compact approach to improving mass transfer in suitable applications.
B&G supports the evaluation, testing, and integration of High-Gravity Rotating Packed Bed (HiGee) technology, from small-scale trials to engineering scale-up.
How It Works
HiGee technology uses a rotating packed bed to generate strong centrifugal forces, creating thin liquid films and droplets that increase gas–liquid contact and enhance mass transfer.
This principle can support processes such as gas absorption, stripping, and separation.
For example, HiGee can be applied to ammonia (NH₃) gas scrubbing, where ammonia is absorbed from a gas stream into a suitable scrubbing liquid.
Process suitability and performance depend on the materials, operating conditions, and system requirements. Small-scale testing can help establish the parameters needed for further development and scale-up.
Application Areas
- Industrial waste-gas treatment
- Gas absorption and scrubbing
- Gas stripping and purification
- Wastewater treatment applications
- Chemical process intensification
- Pilot testing and engineering scale-up
