This research attempts to enhance of the ability of Fuzzy Logic Controller in controlling wastewater
treatment system, highlighting the pH parameter in factory wastewater treatment plants. The research
not only covers methods to monitor and track the pH level in wastewater tank but more importantly,
the control of total wastewater volume by neutralising the pH. Fuzzy logic control has gained more
attention in the control of continuous processes. It utilised both, in the context of deciding and tracking
set-points, and to control the total unwanted water capacity. This paper also discusses suitable level of
pH required which will not damage the water ecosystem. The self-learning fuzzy logic control with
adaptive capabilities alert operator in charge of the pH level automatically. This research includes the
design and development a graphical user interface (GUI) to show the process of pH neutralisation in
wastewater treatment. A fast response system is achieved through GUI which could be monitored and
control remotely using laptop or smartphone, from anywhere. This proposed design will inform engineers
and technicians about the status of the current reading of parameters in the wastewater treatment system
without the hassle of going to the site or control room of the wastewater treatment plant.
This paper aim is to design an education kit for wastewater system that can maintain
the standard parameters of neutralized wastewater by maintaining the suitable pH
(Potential Hydronium) level and temperature of the wastewater from industry by using
fuzzy controller. This study is capable to control the unwanted bacteria by automatic
regulatory and monitoring the temperature, pH and water level. Fuzzy logic method is
use to control and monitor pH level as well as the temperature during clarifying process
because pH control process is a complex physical-chemistry process of strong
individuality of time-varying and non-linearity properties. Pumps used in the prototype
need to be controlled precisely to enable either acid or base to be pumped into mix
tank of the wastewater treatment. The control and monitoring system, which has been
designed through LabVIEW front panel will ease end user in inspection of the
parameters involve in wastewater treatment. The entire system output could be
observed remotely in Data Dashboard application in smartphone or tablet. The GUI
was designed and interfaced with the prototype constructed to carry out the process
of controlling and monitoring the required parameters. Few tests were conducted
repetitively to analyse the performance of the system parameters. It was found that
the controlled set point fixed within the range of pH 7.6-8.4, temperature 25-29.44
Celsius and water level of 20cm in this research that was effectively achieved in the
entire test conducted. In addition, the wastewater system accuracy and performance
is 96.72% and 90.22% respectively.
