Alternative co-digestion scenarios for efficient fixed-dome reactor biomethanation processes

A Recyclable Poly(ionic liquid)s Enzyme Reactor for Highly Efficient Protein Digestion

One of the most significant tasks for proteomic research and industrial applications, is the preparation of recyclable enzyme reactor. Herein, a novel recyclable enzyme reactor has been developed based on monodispersed spherical poly(quaternary ammonium ionic liquid)s particles immobilized trypsin. A new quaternary ammonium ionic liquids functional monomer was first synthesized. The ionic l...

Biomethanation potential of macroalgae Ulva spp. and Gracilaria spp. and in co-digestion with waste activated sludge.

Biochemical methane potential of four species of Ulva and Gracilaria genus was assessed in batch assays at mesophilic temperature. The results indicate a higher specific methane production (per volatile solids) for one of the Ulva sp. compared with other macroalgae and for tests running with 2.5% of total solids (196±9 L CH(4) kg(-1)VS). Considering that macroalgae can potentially be a post tre...

Enhanced Biomethanation in Co-Digestion of Cassava Pulp and Pig Manure Using A Two-Phase Anaerobic System

In this study, the co-digestion of cassava pulp (CP) and pig manure (PM) in a two-phase continuously stirred tank reactor (CSTR) was examined to find the optimum CP-to-PM mixture ratio (w/w volatile solids; VS) and to evaluate the effect of phase separation on the efficiencies of solid destruction and methane production. The results showed that the highest VS removal (29%) and the greatest prod...

ALTERNATIVE MIXED INTEGER PROGRAMMING FOR FINDING EFFICIENT BCC UNIT

Data Envelopment Analysis (DEA) cannot provide adequate discrimination among efficient decision making units (DMUs). To discriminate these efficient DMUs is an interesting research subject. The purpose of this paper is to develop the mix integer linear model which was proposed by Foroughi (Foroughi A.A. A new mixed integer linear model for selecting the best decision making units in data envelo...
