The Modification of Communal Wastewater Treatment Plant (IPAL) Tlogomas Malang Using Sand Filter

The process of blackwater treatment at Tlogomas WWTP still needs to be developed in order to improve the quality of the result, therefore it can be reused and not pollute the environment. This research used concrete sand as filter material to remove the pollutants contained in blackwater. Concrete sand is chosen because it is easily obtained at a relatively cheap price, thus it is suitable to be applied in developing countries like Indonesia. Hopefully, the method of blackwater remediation applied in this research can be re-applied by the community. This way, all parties can contribute to the wastewater management program. Based on the result, visually, the output water of the sand filter method has low turbidity, which indicates that the pollutant content in blackwater has been optimally filtered. Aside from being reused, the processing water also does not have the potential to pollute the environment if it is discharged into the river body
