Abstract:
The objective of this research were to compare the treatment efficiency of commercial media filled Septic-Submerged Anaerobic Fixed-Film Reactor system and the recycled bottle media filled system, and to study the treatment efficiency of Septic-Intermittent Aerobic Filter. Each system was fed by riverside community housing wastewater at flow rate 1 m³/d and organic loading rate 0.25 kg.BOD/m³-d. It was found that the treatment efficiency of Septic-Submerged Anaerobic Fixed-Film Reactor system that contained recycled bottle media was similarly to the system that used commercial media. The recycled bottle media filled Septic-Submerged Anaerobic Fixed-Film Reactor system had the efficiency in suspended solids, settleable solids, BOD, sulfide, TKN, grease and oil, and fecal coliform were 64.20%, 95.87%, 65.45%, 44.12%, 5.52%, 65.35%, and 97.33% respectively. The treatment efficiency of Septic-Intermittent Aerobic Filter was greater than Septic-Submerged Anaerobic Fixed-Film Reactor's efficiency. The treatment efficiency of Septic-Intermittent Aerobic Filter was the most effective treatability, the efficiency in dissolved solids, suspended solids, settleable solids, BOD, sulfide, TKN, total phosphorus, grease and oil, and fecal coliform were 11.77%, 45.97%, 90.00%, 93.12%, 75.71%, 76.09%, 17.39%, 72.45%, and 97.56% respectively
