Abstract

Purpose of the study: Treatment of the wastewater coming from households, laboratories, big AC plants etc. is very important. For this the use of low cost activated carbon is highly preferable and eco-friendly making great improvements in the quality of wastewater also. The aim of this study is to clean the wastewater collected from Air Port Height Campus of Caledonian College of Engineering, by the use of activated carbon in batch process.


Methodology: Wastewater sample is collected from Airport height campus of CCE, Oman. It was treated using activated carbon in batch study, and the quality of water is tested in terms of % variation in COD in the college laboratory. Time, activated carbon dose, pH, and temperature variation were conducted on 50 ml batch size.


Main Findings: Maximum COD removal was 88% at carbon dose 0.2g, time 30 min, pH 5 and temperature 550C.The results obtained from experiments were also analysed by Langmuir and Freundlich isotherm. Results shows that the process fit well with Freundlich isotherm because R2 values are higher for the linear relationships.


Applications of this study: The results obtained from the experiments clearly indicate that the quality of the treated water has improved and if some more parameters that are concerned with the purity factor can be introduced, this water can be made available in form of non-potable usage also. So, this study is highly beneficial for our earth as well as human beings.


Novelty/Originality of this study: The experiment performed is very eco-friendly as low cost and easily available chemicals and activated carbon is used here, so it will relieve us from the expensive and complicated methods for wastewater treatment.
