Abstract
Jumputan is one of South Sumatera art crafts that increasingly produced by textile industries in the region. Dyeing and washing process are applied in jumputan production that will contribute to the increase of chemical content in waste water. This research will address the solution to this problem by investigating the waste water treatment using continuous adsorption process with activated carbon made from betel nuts as an adsorbent. Activated carbon was produced at carbonization temperature 500°C and activated by 0.5 M HCl and sized 18 mesh sieve. Adsorption was performed using Fixed-bed adsorber made from fiberglass with 100 cm height and 10 cm diameter. Jumputan liquid waste was fed from the top of the column at 58 mL/min. The height of bed was varied at 5, 15, 25 cm and sampling time was performed in 30, 60, 90, 120, 150 min to determine COD reduction. Optimum condition of this process is 25 cm of bed height and 150 min of sampling time that reduces COD value of waste water to 99.69%.
Highlights
South Sumatera province especially Palembang, has popular art crafts such as songket, jumputan, and wood cabinets craved
The results showed 98.61% reduction in chemical oxygen demand (COD); 98.50% reduction in biological oxygen demand (BOD); 87.50% reduction in total suspended solid (TSS); and 96.30% reduction in Chrome
This study examines chemical oxygen demand in the samples
Summary
South Sumatera province especially Palembang, has popular art crafts such as songket, jumputan, and wood cabinets craved. Batch investigation on jumputan wastewater treatment by using activated carbon, zeolite, and fenton reagent, within 30 minutes operation, COD reduction was 38% and color degradation was 10% [9]. The preliminary assessment of the jumputan wastewater treatment using betel nuts activated carbon had been conducted in a batch process [7]. This research will examine chemical oxygen demand (COD) degradation in jumputan wastewater treatment by using continuous fixed-bed adsorber with the various height of bed and sampling time. Aims of this research are to improve the quality Musi river, due to continuously increased turbidity, up to double maximum turbidity numbers [3], and to get appropriate technology for processing jumputan liquid waste that can be directly installed and used by craftsmen
