Removal of nickel ion from electroplating wastewater using double chamber electrodeposition cell (DCEC) reactor partitioned with water hyacinth (Eichhornia crassipes) leaves Djaenudin, Widyarani, H R Hariyadi et al. -The design of a PC-based real-time system for monitoring Methane and Oxygen concentration in biogas production M Yantidewi, M S Muntini, U A Deta et al. Abstract. Distribution of water hyacinth (Eichhornia crassipes), generally considered as a water weed, that has been a problem which can harm the environment, irrigation system, and agriculture. However water hyacinth can be used in biogas production because it has large enough amount of hemicellulose contents. The purpose of this study was to know the effect of F/M ratio to biogas production from water hyacinth waste with Liquid Anaerobic Digestion (L-AD) method. A series of laboratory experiments using biodigester were performed in batch anaerobic operation at room temperature. F/M ratio that used in each reactor was 39.76, 20.03, 13.32, and 10.01. Degradation process was done in 60 days. The result showed that F/M ratio effects to the biogas production. The best performance of biogas production from this research will be obtained if F/M ratio is in the range of 10.01-20.03 (correspond to 25%-50% of rumen fluid) with water hyacinth as the main substrate.

“…FW has a high content of potentially biodegradable components such as proteins and fats (Cadavid-Rodríguez et al 2019); therefore, FW is susceptible to be transformed into products such as low-value animal feed, biogas and organic acids. Biogas production from FW using Anaerobic digestion (AD) has been reported from commercial FW such as tuna, seabream and sturgeon (Eiroa et al 2012;Hadiyarto et al 2015;Greggio et al 2018). Recently, artisanal FW was proved as a suitable substrate to produce biogas.…”

In this research, operational parameters were assessed to optimise the production of volatile fatty acids (VFA) from artisanal fish waste (FW) using mixed-culture fermentation. The experiments were performed using a randomised block design with pH and Inoculum/Substrate (I/S) ratio as factors with three pH levels (5, 7 and 9) and five I/S ratios levels (0.20, 0.15, 0.10, 0.05, 0.00) with VFA production, total ammonia nitrogen (TAN), biogas and soluble chemical oxygen demand (sCOD) as response variables. The results indicated that pH and I/S ratio significantly influenced VFA production and the other variables evaluated. The highest VFA concentration (54.5 g/L) was obtained at pH 7 and with an I/S ratio of 0.05. These conditions were also optimal for TAN and sCOD. External pH control was proved as unnecessary as the highest VFA production (70.3 g VFA/L) was obtained without pH control. In these conditions, the fermentation broth was able to maintain its pH between 6.6 and 7.7. The VFA profile had acetic (35%) and butyric (32%) acids as the dominant species and propionic, iso-valeric and iso-butyric were minor species (< 10%). An economic assessment evaluating the establishment of a FW VFA biorefinery in Tumaco, Colombia was performed including capital, operational and labour cost, discounted payback period and cost curves. These results evidenced the potential of artisanal FW as a raw material for producing high concentrations of VFA and smooth the path for the establishment of a VFA and biogas biorefinery from FW.
