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.
