    Peningkatan Remediasi TSS dan TDS Air Limbah Rumah Potong Hewan Sapi Kota Pekanbaru dengan Proses Biofilter Kombinasi Anaerob-Aerob Bermedia Potongan Plastik untuk Media Hidup Ikan Budidaya

    Liquid waste slaughtering house (RPH) containing a high concentration of organic matter, suspended solids and colloidal materials such as fats, proteins, and cellulose. If directly discharged into the water can cause problems for aquatic organisms. It is necessary for processing. The purpose of this research is to reduce the concentration of suspended solids (TSS) and dissolved solids (TDS) in wastewater slaughter cows Pekanbaru. Decrease in the concentration of TSS and TDS performed with anaerobic-aerobic biofilter system mediated plastic bottle containing a piece of scrap plastic and without media (control). Anaerobic-aerobic biofilter performance of media has been very good. This is evident from TSS concentrations decreased effectiveness of the first observation to observation of the 5 ranges between 76.29 to 90.34%. While the decline in the effectiveness of TDS concentrations ranged from 71.58 to 86.88%. In addition, the performance of the anaerobic-aerobic biofilter without media also showed decreased concentrations of TSS and TDS. It's just lower than the decrease effectiveness of media biofilter. Effectiveness of TSS concentrations decreased during the five observation times ranged from 38.78 to 52.88% and a decrease in the effectiveness of TDS concentrations ranged from 32.43 to 43.42%. Further testing of farmed fish survival rate with processed wastewater biofilter mediated high enough. Survival rate jambal reached 97%, 80% tilapia and carp 37%. While survival rate with processed wastewater biofilter without media, all the fish test are dying.
