| Summary: | In Sarawak, peat water is one of the potential raw water sources as a domestic water
supply, particularly for the communities of the rural areas that do not have access to the
municipal water supply. However, the peat water must be treated before it is used as a
water supply due to the high acidity level and concentration of organic material. The
previous study has proved that the electrocoagulation process is an effective treatment
system to treat peat water due to its high-efficiency pollutant removal, environmentally
friendly and low-cost technology. However, most of the electrocoagulation process
studies are performed on a small scale or lab scale only. Hence, scaling up the
electrocoagulation system must be considered to fully utilise the electrocoagulation
treatment and meet the growing water demand, especially for rural communities. This
research study aims to propose a continuous electrocoagulation peat water treatment
design model for domestic usage in Sarawak rural areas where the design simulation
development will adopt the most suitable and high accuracy model which is either
kinetic or statistical models. Then, the respective model will be further used to simulate
the electrocoagulation process for scaling up purposes. It is found that the variable order
kinetic (VOK) model derived from the Freundlich isotherm results reveals good
agreement between the simulated data and the experimental data compared to VOK�Langmuir and VOK-Jovanovic for kinetic modelling. This result indicates that the
VOK-Freundlich model can predict the pollutant concentration at different treatment
times by knowing the initial pollutant's concentration only. Besides, the predicted data
obtained from the statistical model developed using Free Trial Design Expert 13
software by adopting Response Surface Methodology-Central Composite Design
(RSM-CCD) is close to experimental data based on the coefficient of determination, R
2
and nonlinear chi-squared test, χ
2
. Hence, the statistical model is the most suitable
approach to simulate the continuous electrocoagulation system in treating peat water. In
conclusion, the developed statistical model can be applied to other continuous
electrocoagulation for peat water treatment design systems where the electrocoagulation
process can be predicted with various operating parameters, which are treatment time
and current supply, without conducting an actual experiment. |
