In this project, a treatment pond built in 1985 at the Universiti Teknologi Malaysia (UTM) has been studied. Figure 1.1 below shows where UTM is situated. The treatment pond was originally built for a population of 8 000 P.E. but is currently treating waste water from around 10 500 P.E. from the university area. The treatment pond consists of two parallel lines each treating equal amounts of waste water. The treated water is discharged to a small stream next to the treatment pond. The current discharged waste water is not complying with Standard A according to Malaysian requirements. At the moment the pond is only complying with standard B quality which is a lower quality standard for treated waste water. The university would like to upgrade the treatment facility so that it can comply with Malaysian Standard A requirements as the water downstream is used for canoeing by UTM students. The idea is that a new treatment facility could also be used for educational purposes for students from the university. Moreover, an improved treatment facility at the university also goes hand in hand with Malaysia’s national goals to reach a more effective and better management of waste water. In order to get a deeper understanding of the water quality and its flow characteristics to the current treatment pond, sampling and different kinds of measurements have been performed. The obtained information is important as the result of the samples and measurements will be used as a basis when designing an improved and more effective treatment facility.

1.3 Objective The objective of this master thesis project is to propose and evaluate upgraded waste water treatment facilities which can improve the treated effluent waste water quality at Universiti Teknologi Malaysia. A new treatment facility should have a footprint area of 25% compared to the present treatment pond, as the area around the current treatment pond is planned for recreation. The upgraded treatment facilities must also be able to perform a better treatment of the waste water compared to the system used today. The requirement is that the effluent can comply with an effluent of Standard A quality according to Malaysian directives.   15
