| Summary: | The conventional wastewater treatment plant is still struggling to meet ammonia and nitrate discharge limits in Malaysia. In this study comparison of synthetic domestic wastewater treatment (DWW) was established between conventional activated sludge (CAS) and submerged attached growth activated sludge (SAGAS) systems to find appropriate solution. The submerged attached growth bio‒carrier (TAVID) was printed through vat polymerization of acrylate-based resin using stereo‒lithography (SLA) technology to utilize as submerged attached growth bio‒carrier. The specific surface area (SSA) of TAVID was 971 m2⁄m3, with density, zeta potential and contact angle of 1.15±0.05 g/cm3, -30.46 mV, and 43.6° ± 2.8° respectively, indicating high SSA and hydrophilic behaviour of bio‒carrier. The effects of cycle time (CT) and filling ratio (FR) were studied in sequential batch mode. |
