Anaerobic treatment of olive oil mill wastes, namely black water and prina, was investigated in batch reactors. Biochemical methane potential (BMP) tests were conducted to determine the anaerobic biodegradability of black water and/or prina. With these BMP tests the biodegradability of olive mill wastes (OMWs) at different initial chemical oxygen demand (COD) concentrations and corresponding me...

carbon nanostructures are famous structures which are used in several industries such as separation, treatment, energy storage (i.e. methane and hydrogen storage), etc. a successful modeling of activated carbon preparation is very important in saving time and money. there are some attempts to achieve the appropriate theoretical modeling of activated carbon preparation but most of them were almo...

The present work deals with the potential of olive mill wastes as a C source for soil C sequestration strategy, which is based on the high lignocellulosic content that makes these wastes to degrade slowly during composting and after land application. A C balance was performed during the whole life cycle of two different two-phase olive mill wastes (TPOMW): C losses were calculated during the co...

This article reports studies on the feasibility of increasing the decoloring capacity of a granular activated carbon (GAC) by using oxidation with air at 350 degrees C to modify its surface activity and porosity. The GAC, obtained from olive stones, had a maximum decolorization capacity of 92% for doses of 20 g/l, while the maximum decolorization capacity of the modified granular activated carb...

Purpose. To depollute water contaminated by phenol using the adsorption process in a batch reactor with valorization of olive pomace for preparation activated carbon to be used as an adsorbent. Methodology. In this present work, study on influence four principal parameters yield during treatment polluted were studied, namely: mass, contact time, initial concentration and stirring speed. additio...

Adsorption is a fundamental process in the physicochemical treatment of municipal wastewaters, a treatment which can economically meet today's higher effluent standards and water reuse requirements. Activated carbon is the most effective adsorbent for this application. Expanded-bed contact systems permit most efficient use of granular carbon for waste treatment. The adsorption process is enhanc...

Recycling trend has transformed the prerequisites of our cravings. Makeover waste material into useful goods become inevitable. Bio shares a major portion materials, hence pursued for recycling. Activated carbon from bio been reported remarkable in electrochemical performance (capacitance, charge density, charge-discharge ratio etc.). This survey data compiled different wastes as source activat...

the performance of olive stone activated carbon (osac) for sorption of cu2+, zn2+ and ni2+ ions was investigated via batch technique. osac materials were prepared under different physially activation conditions. olive stone waste was physically activated with n2 gas and steam gas at 900oc at 3.5h hold time (osac-3) was choice as the best one for cu2+, zn2+ and ni2+ removal. characterization for...
