Abstract
Untreated wastewater and improper wastewater treatment from domestic and industrial
sources continue to degrade water quality around the globe. The greatest challenge
currently lies in shifting our perspective on wastewater, aiming to perceive it
not merely as a problem but as a potential solution. Several challenges have limited
wastewater monitoring and assessment. These limitations include real-time monitoring
and aging infrastructure, which can impact the accuracy, efficiency and reliability
of the obtained information. These conventional assessment methods are unable to
handle the increasing volume and complexity of contaminants in modern wastewater,
resulting in poorly treated wastewater. To address this issue, an electronic sensor
has been introduced to overcome such crises, providing a better assessment of wastewater
quality. Electronic sensors offer a real-time and efficient means to evaluate various
parameters in wastewater, providing valuable insights into the composition and potential
environmental impact. The potential of wastewater quality assessment using electronic
sensors represents a promising avenue in modern environmental monitoring.
This innovative approach allows for continuous and automated monitoring, enabling
timely detection of changes in water quality. The utilization of electronic sensors
in wastewater assessment holds the potential to enhance our understanding of pollution
sources, to facilitate rapid responses to environmental challenges and to contribute
to the sustainable management of water resources. In this review, a comprehensive
study was performed on electronic sensors to evaluate their physical and chemical
properties, as well as a microbial analysis for wastewater quality assessment. Possible
challenges and future directions for their development have also been investigated
critically. This study will assist future research on electronic sensors which will
be highly important for sustainable wastewater assessment.
