Abstract
Industrial hygiene is an important aspect of any workplace environment, especially for the industrial domain. A previous study has shown that high ammonia levels were present in a wastewater treatment facility in Romania. The initial ventilation strategy was not efficient in maintaining pollutant concentrations within standard safety limits. An optimization of the initial ventilation system was realized, but CFD results and on-site measurements have shown that high local concentrations were still present. Two local exhaust methods have been proposed and analysed in order to improve the quality of the air inside the hall. A CFD approach has been used for the preliminary design process. The results indicate that both local exhaust solutions offer great improvements over the general dilution-based system, but only one can be applied.

Summary
Even though modern industry has mainly developed within the past century, the concept of “industrial hygiene” has been developed over the course of almost 20 centuries. Since antiquity there has been an awareness regarding the safety and health of the workers, especially of those that were operating in mines or that were exposed to different toxins like lead, sulfur, mercury or nitric acid. Industrial hygiene is a complex science which aims to provide adequate workplace conditions by anticipating, recognizing, evaluating and controlling indoor factors to avoid injury, illness and any potential health hazards. One of the most important aspects of a healthy workplace is to provide an adequate indoor air quality (IAQ) and thermal comfort for the workers [(OSHA, 2011), (WHO, 2006)]. Properly designing an industrial ventilation system can become a difficult task, especially nowadays when energy efficiency has become a critical factor in the conception of any HVAC installation. A balance needs to be found so that all safety factors are respected with the least consumption of energy
