EFEKTIVITAS BIOFILTER DALAM MEREDUKSI POLUTAN PADA AIR LIMBAH RUMAH SAKIT DI KOTA PALU

The existence of pollutants in hospital wastewater has the potential to pollute environment, so they are obliged process liquid waste before it is released into nature. To ensure that feasible be discharged necessary treat through a Wastewater Treatment Plant, one which aerobic anaerobic biofilter method. This study aims determine effectiveness reducing terms physical, chemical and biological parameters. uses quasi experiment with sampling technique composite sample by time. Color odor parameters were checked organoleptically, while pH temperature measured insitu using multifunctional portable device. Parameters BOD, COD, NH3, TSS MPN Coliform analyzed laboratory for quality assurance each duplo. results Anutapura Hospital's treatment still slighly cloudy but odorless, this not accordance standards Minister Environment Regulation Number 5 2014, on contrary at Madani Hospital color have met standards. values temperature, pH, COD standard requirements both hospitals even from inlet point. because good preliminary carried out flows biofilter. While value coliform, outlet point exceeded standard. percentage BOD reduction 70.2% 47.6%, 53.4% 27%, NH3 95.9% 69.4% 65.2% 70.2%. Based data, concluded increasing necessary.
