Abstract

This project is to study the effect of overall transfer coefficient, K and oxygenation capacity, R onUTP lakes. It contains 5 objectives which are, to study the non steady state condition of UTP lakes samples, the effect of different air flow rate used on K and R values, the effect of different depth used in aeration tank on K and R values, the effect of different waste material on K and R values and finally the effect of different diffuser arrangement on K and R values. Transfer coefficient and oxygenation capacity are important in any aeration study since they are the parameters to indicate the oxygen transfer and oxygen dissolve behavior in any water sample. A key water quality parameter common to each is dissolved oxygen or the transfer of gases into or out of water. As a result, aeration can be critical in maintaining good water quality conditions for all these process. Aeration is a process that implies bringing water and air into contact to facilitate oxygen transfer and thus aeration unit is the equipment used to observe these processes. The methodology of experiment is to aerate the water samples in aeration tank (Armfield Unit wlO) with specific procedures and disciplines. Since the project is relevant to the aeration, student has to study the aeration itself. The aeration definition, applications, equipments, type of aerators and limitations are considered study materials. But to be specific, the experiment only deals with non porous diffuser (sparger tube) which is default diffuser ofthe equipment. At the end of experiments it was found that the K value for lake A (Behind the UTP mosque) is higher than lake B (Near the Ruby block) for all objectives. R value is proportionally to K value if all variables kept constant, but R value will be most effected if the experiment is conducted at difference average temperature. In overall, lakeA give better aeration result compared to lake B, but the differences results does not make any significant effect in any industries applications since the difference is very small.
