Abstract

Phosphorus in river can be classified to three major sources such as industry, agriculture and wastewater treatment plant. Conventionally, to treat phosphorus it requires a complex treatment process with additional chemical cost. Thus, this present study has been design with an aim to develop a low-cost rock filter system to remove phosphorus from domestic wastewater. A pilot-scale rock filter with steel slag a filter medium has been constructed and the objective was to study the performance of a pilot-scale vertical aerated steel slag filter (VASSF) for phosphorus removal from domestic wastewater. Steel slag has been selected for filter medium due to its content which highly contained Al, Ca, Mg for enhanced phosphorus adsorption and also their readily locally available. The pilot-scale vertical aerated steel slag filter has been operated in laboratory for treating domestic wastewater from Universiti Tun Hussein Onn Malaysia (UTHM) wastewater treatment plant located at Tun Fatimah Residential College. The influent and effluent samples of VASSF were collected and analysed for Total Phosphorus, Biochemical Oxygen Demand5, Chemical Oxygen Demand, turbidity, Total Suspended Solid, pH and Dissolved Oxygen once a week to monitor the filter performance at different filter depths. Results from this study show that at the depth of 0.75m the vertical aerated steel slag filter has efficiently remove 89%, 76%, 64% and 94% of Total Phosphorus, Biochemical Oxygen Demand5, Chemical Oxygen Demand and Total Suspended Solid, respectively. For Dissolved Oxygen and pH profiles, the vertical aerated steel slag filter effluent values have increased after the treatment. The Dissolved Oxygen is increase at the depth of 0.75m and above about ranged from 7.85 - 8.12 mg/L to 7.72 - 8.46 mg/L, whilst pH increases from ranged 6.64 - 6.79 to 8.37 - 8.99. In conclusion, the filter provides an effective removal performance by using low cost media in removing phosphorus. By complying with Malaysian Environment Quality (sewage) Regulation 2009, the sample treated for all parameters are within permissible limit of standard B.
