Abstract

One of the major factors affecting the productivity of workers in industry is quality of air in the working ambience. The quality of air can be characterized by means of microbial contaminants, chemicals, gases, allergen, odour or any mass or energy stressor that can induce health issues. This study is concerned with the presence of excessive detergent odour in industrial laundries. Odours are basically chemicals dissolved in air which we may be perceived by the sense of olfaction and always referred to as unpleasant smell. As for the case of industrial laundries, the effect of detergent odour becomes significant as cleaning processes simultaneously discharge high detergent concentration to the surrounding air which may lead to serious health issues apart from reducing workers’ performance. Therefore, a design of liquid spray gas scrubber had been proposed in this work as a means to overcome the problem. A prototype has been designed and developed to prove the working principle of the scrubber. By taking that the scrubbing efficiency is independent of the chemical specie, a solution of ammonium hydroxide (NH4OH) was used as a source of odour as alternative to detergent. This is due to the unavailibity of tools to measure detergent odour while concentration of NH4OH in the scrubbing liquid, i.e. water can be easily determined. From the tests conducted, scrubbing efficiency up to 36% is obtained in a single stage, which is encouraging considering that the scrubber head was a simple shower nozzle. With improved designs of the spray, the scrubber unit may be used to improve indoor working environments.
