Performance of a modified multi-stage bubble column reactor for lead(II) and biological oxygen demand removal from wastewater using activated rice husk

Preparation of Activated Carbon from Green Coconut Shell and its Characterization

“…Activated carbons can be prepared by either a physical method or chemical method [8]. It is produced from a large number of carbonaceous raw materials like coal, lignite, wood and some agricultural product like rice husk [9,10], nut shell [11], coconut shell [12,13], pea nut [14,15], sugarcane bagassage [16], tamarind wood [17], saw dust [18] and industrial waste products. The cost of Agricultural wastes are very low so it is considered to be a very important feedstock for preparation of AC [19].…”

Performance of Laterite Soil Grains as Adsorbent in the Removal of Chromium

“…The widely used physico-chemical techniques to treat wastewater includes adsorption, ion-exchange, electrodialysis, chemical reaction, filtration, coagulation/flocculation, reverse osmosis etc. (Sahu et al 2009) (Owlad et al 2008). Choice of reliable treatment method depends upon effluent characteristics such as flow rate, pH, temperature, heavy metals, and trace organics.…”

Recovery of Lignocellulosic Waste from Date Palm in Activated Carbon

“…In recent years, many studies have focused on the residues valorization from agricultural and agro-industrial sectors in active coals such as rice husks [7], olive [8], cherry [9], dates pits [10], peanut [11], almonds [12], [13] and coconut shells [11], [14] and [15]. In Algeria, the date palm occupies an area estimated at 167,000 hectares for a palm trees number estimated at more than 18.6 million palm trees [16].…”
