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.
