Odour emission from open pond palm oil mill effluent system case study of united oil palm (uop) / Nik Rosdaini Nik Hussin
Pada masa kini, minyak sawit adalah salah satu sumber utama ekonomi Malaysia. Walau bagaimanapun, ia akan menjana banyak efluen. Sistem kolam rawatan adalah salah satu rawatan konvensional yang digunakan untuk merawat kumbahan sebelum dilepaskan ke sungai. Masalah utama rawatan kolam ini adalah pelepasan bau. Tahap kepekatan bau di United Oil Palm (UOP) telah ditentukan dengan menggunakan ‘dynamic olfactometry’ yang merupakan salah satu kaedah pengukuran bau dalam unit kepekatan bau. Kepekatan hidrogen sulfida dan ammonia di lokasi ditentukan dengan Odotracker. Kepekatan bau tertinggi dicatatkan adalah 10299 OU/m³ dari kolam anaerobik. Kepekatan bau terendah adalah 5577 OU/m³ dari kolam penyejukan. Kepekatan tertinggi hidrogen sulfida adalah 0.557 ppm dan kepekatan tertinggi amonia adalah 226.38 ppm. Faktor sekitar seperti kelembapan udara dan suhu udara memberi kesan kepada pelepasan bau. Kelembapan udara dan suhu udara yang tinggi akan menghasilkan kepekatan bau yang tinggi. Suhu kolam dan volatile fatty acid (VFA) dalam air sisa akan menyebabkan bau. Keputusan menunjukkan bahawa peningkatan VFA akan menyumbang bau yang tinggi. Asid butyric tertinggi dicatatkan adalah 433.96 mg / L. _______________________________________________________________________________________________________ Nowadays, palm oil is one of the main sources of Malaysia's economy. However, it generates a lot of effluent. Ponding system is one of conventional treatment used to treat effluent before discharge to river. The major problem of ponding treatment is odour emission. The level of odour concentration at United Oil Palm (UOP) was determined using dynamic olfactometry which is one of odour measurement methods to determine level of odour concentration. The concentration of hydrogen sulfide and ammonia at location is determined by using Odotracker. The highest odour concentration recorded is 10299 OU/m³ from anaerobic pond. The lowest odour concentration is 5577 OU/m³ from cooling pond. The highest hydrogen sufide concentration is 0.557 ppm and the highest ammonia concentration is 226.38 ppm. Surrounding factor such as humidity and air temperature give effect of odour emission. The higher of humidity and air temperature will give high odour concentration result. Pond temperature and volatile fatty acid in wastewater will result of odour. From the result shows that the increase of volatile fatty acid will give high odour concentration. The highest butyric acid is 433.96 mg/L that give high odour concentration.
