ABSTRACT
Fatty alcohol production by trans-esterification and hydrogenation process produces fatty alcohol, methyl esters, glycerin and also glycerin pitch as wastes. Glycerin pitch is a dark-brown viscous liquid, which contains 1.8 - 2 million mg/! organic matters in term of COD. Glycerin
pitch disposal could become a serious problem that needed to be handle, as
biodiesel utilization from methYl esters will be increasing in the future. The combined treatment of glycerin pitch and other fatty alcohol
wastewater in anaerobic process is the technique investigating in this study. The experiment in this study were divided into preliminary and main ones, both carried out at the temperature of 37"C with the following parameters evaluated, namely COD, MLSS, pH, TVA, alkalinity and biogas production.
The preliminary experiment was conducted in an anaerobic batch digester with variables, i.e, the type and amount of inoculum and the type of dilution wastewater used and the ratio of glycerin pitch to wastewater. The experiment recommended the utilization of inoculum from P.T. Batantas Megah in amount of 25% working volume be used in the main experiments. Moreover, the wastewater snitable for dilution was the combination of wastewater from methyl ester distillation and glycerin water evaporation unit with the COD of 46,720 mg/l.
The main experiments were conducted both in the anaerobic batch digester and anaerobic baffled reactor (ABR) with the variables i.e. influent concentration and glycerin pitch concentration. The ratio between the dilution agent (methyl esters distillation and glycerin water evaporation unit) and glycerin pitch in the normal condition during experiment was (81 : 62) : 1.8, respectively. The experiment result shows that the dilution of influent concentration increased COD reduction efficiency (11) and biogas production. The 11 for normal concentration (N); 0.8N; 0.6N; O.4N were 34.8%; 43.9%; 46.3% and 47.6% while the biogas produced were 310 ml; 326 ml; 741 ml and 1.535 mi. respectively. Meanwhile, by increasing the glycerin pitch concentration to 1111"'" and 120% from normal condition decreased the 11 from 47.6% 10 l:!.4%IlJO% normal) and Ｕ Ｎ Ｑ ｾ Ｂ ＼ Ｑ Ｒ Ｐ normal). The best treatment performance was achieved by using ABR with '1 of 80.4% for influent concentration of O.4N.
