Air Quality Control

The global iron and steel manufacturing sector is challenged by environmentally conscious local communities who keep a watchful eye on air emissions from the iron and steel plants. Inadequate air quality control can frequently prevent a plant from fully employing its full capacity due to operating restrictions.

Hatch’s air-quality control engineers can troubleshoot and upgrade existing systems. They can also design new systems and provide operational assistance.

Optimally designed air-quality control systems allow a company to meet its air emissions and occupational hygiene goals at least cost, and allow it to achieve its full production potential.
