Air Quality Interventions
John Thompson services, maintains, retrofits and erects electrostatic precipitators and fabric filter plants. Our technology partnership with Hamon Belgium enables us to offer our customers new electrostatic precipitators and flue gas desulphurisation plants.
Through our technology partner, Wahlco USA, we bring you a world of experience in clean air solutions. We have installed fabric filter plant on coal-fired utility boilers with capacities of 200MW and above.

Electrostatic precipitator
- Design, manufacturing and construction of electrostatic precipitators
- Complete refurbishment of electrostatic precipitators
- Day-to-day and outage maintenance of electrostatic precipitators
- Supply of electrostatic precipitator spares
- Supply and installation of high-frequency power supplies
Hybrid ESP-Filter
This hybrid solution can help reduce particulate emissions to compliance. The fabric filter collects higher levels of particulate, and finer particulate, than any other ESP-filter of an equivalent footprint.
It combines an electrostatic precipitator (ESP) with a fabric filer unit with a suitable air to cloth ratio.
The fabric filter unit is located either downstream of the ESP or within the existing ESP. This is achieved by replacing one or more fields of collecting plates with the fabric filter modules.

Fabric Filter Plants
- Design, manufacturing and construction of fabric filter plants
- Retrofitting electrostatic precipitators with fabric filter units
- Day to day and outage maintenance of fabric filter plants
- Supply of filter bags and other spare parts

Flue Gas Desulphurisation
Our agreement with Hamon enables us to design, manufacture and construct flue gas desulphurisation plants.
We provide the following range of FGD solutions:
- dry sorbent direct injection system
- semi-dry circulating dry scrubber
- semi-dry systems with rotary atomisers or spray nozzles
- wet systems with lime or limestone
- wet seawater desulphurisation
- Day-to-day and outage maintenance services on FGD plants.
