Utilization of bintaro shells as activated carbon to reduce phosphate in laundry wastewater Martogi - Pasaribu
Journal of Environmental Engineering and Waste Management Vol 5, No 1 (2020)
Publisher : President University

Laundry wastewater is dangerous if it is immediately disposed into a river without treating it first. One of the chemicals contained in laundry wastewater is a phosphate compound. If laundry wastewater is discharged directly into the river it will increase the phosphate content as a nutrient in river water which can be dangerous for living creatures. The high nutrient in the river will cause eutrophication in the river which will adversely affect aquatic biota. One treatment that can be done is the process of adsorption with activated carbon made from bintaro fruit shells.

Publisher : President University

The oxidation process as the activated sludge (AS) system has been implemented widely in urban and industrial wastewater treatment. Oxidation ditch can be categorized as an advanced aeration activated sludge. Integrated Fix-Film Activated Sludge (IFAS) process has been already developed for decades that was a reasonable approach for technology to upgrade the activated sludge wastewater treatment plant (WWTP). IFAS processes are a combination of biofilm reactors and activated sludge processes, biofilm is introducing and retaining as the carrier media for microorganism growth. Both IFAS and AS processes can achieve similar percent removal of COD and ammonia. Current WWTP’s development was food chain reactor (FCR) which mainly IFAS process of engineered media that combining with natural plants with the plant roots submerging into the reactors. The references review and secondary data of the application in Jababeka’s WWTP-2 for both AS and FCR system showed that FCR is needless parameters to be controlled. In both AS and FCR have KPIs of flow rate (m3/day), F/M ratio, energy consumption (kWh/m3 wastewater), Oxygen supply (kgO2 / m3 wastewater in each reactor, % removal of COD, BOD, TSS, NH3, TKN, NO2, and heavy metals, and pH, Dissolved Oxygen, microorganism performance in the reactor. Different from AS, the FCR system is not required to control the parameters of sludge retention time (SRT), recirculated activated sludge (RAS), sludge volume index (SVI), and mixed liquor suspended solids (MLSS)of activated sludge.
