| Summary: | The removal of phosphorus from wastewater is a common procedure. Improving water quality is the aim
of wastewater treatment. There are many types of conventional methods that have been used for the removal of
phosphorus. Phosphorus reaction with chemicals can be removed immediately from water. However, the use of
chemicals often increases the cost of wastewater treatment. This study aims to investigate the physical and
chemical characteristics of RCA that influence the removal of phosphorus, as well as the percentage of phosphorus
removal using RCA of two different sizes namely, 5 mm to 10 mm and 25 mm to 30 mm. The samples taken from
the influent and effluent filters were tested and analysed in terms of the uptake capacity of phosphorus (q) and the
percentage of phosphorus removal (%). The highest percentage of phosphorus removal achieved was 99.54% in the
initial concentration of 10 mg/L by RCA measuring between 5 mm to 10 mm while the lowest percentage of
phosphorus removal was 66.25% in the initial concentration of 50 mg/L for RCAs measuring between 25 mm to 30
mm. Furthermore, RCA achieved the highest uptake capacity (q) of 3.45 mg/L in the initial wastewater
concentration of 50 mg/L. In conclusion, RCA has the potential to remove phosphorus, particularly in low
concentrations of synthetic wastewater and high pH conditions. |
