Pengaruh Penambahan Trace Metal (Molybdenum & Selenium) terhadap Pembuatan Biogas dari Sampah Organik dan Kotoran Sapi (Jurnal Teknik Kimia USU, 2017)Trace metal are essential for the enzyme cofactors in methane formation, but its availability of natural is not enough so that the necessary additional trace metal. The purpose of this study is to determine the effect of ...
Acclimatization Process on Hybrid Upflow Anaerobic Sludge Blanket Reactor (HUASBR) using Bioball as Growth Media with OLR Variation for Treating Tofu Wastewater (Oriental Journal of Chemistry, 2018)Wastewater of tofu industry contains very high organic content, then anaerobic process is the most suitable for degrading this liquid waste. The hybrid upflow anaerobic sludge blanket reactor (HUASBR) was applied in this ...
Effect of Cu-Purolite A400 Resin on Adsorption of Nitrate and Nitrite in Wastewater Treatment (Malaysian Journal of Analytical Sciences, 2019)The exceedance of nitrate and nitrite concentrations over the water standard quality has caused potential human health dangers such as blue baby syndrome and the growth of aquatic plants (eutrophication). In this work, a ...
The Effect of Organic Loading Rate Variation on Digestion of Tofu Wastewater using PVC Rings as Growth Media in a Hybrid UASB Reactor (Oriental Journal of Chemistry, 2018)Tofu wastewater contains high organic matter potentially pollute the surrounding environment. An appropriate process for treating tofu wastewater is an anaerobic process which utilizes microorganisms in degrading organic ...
Physical and Biophysical Pretreatment of Water Hyacinth Biomass for Cellulase Enzyme Production (Chemical and Biochemical Engineering, 2016)One practical way to control water hyacinth overgrowth due to eutrophication is by utilizing it as a substrate to produce cellulase. Water hyacinth was subjected to pretreatment to degrade lignin and improve microbes’ ...
