Abstract Biochar properties are highly dependent on the feedstock type and operational conditions during thermochemical processing, in particular slow pyrolysis. To clarify this aspect, nine biochars were produced by pyrolyzing a macro TGA at 400, 550, 650 °C three different decorticated chopped biomasses. The studied biomasses representative of conifer (black pine) deciduous (poplar willow) wo...

textile wastewater contains substantial pollution loads in terms of chemical oxygen demand (cod), biological oxygen demand (bod), total suspended solids (tss), total dissolved solids (tds) and heavy metals. phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (amats) is well established environmental protective technique. a lab scale stud...

the present study was undertaken to investigate and optimize the possibility of xanthan gum production by xanthomonas campestris ptcc1473 in 500ml shake flasks on the second grade date palm. using an experimental response surface methodology (rsm) coupled with a central composite design (ccd), three major independent variables (nitrogen source, phosphor source and agitation rate) were evaluated...

The removal of 18 bisphenols at wastewater relevant concentrations (?g L ?1 range) was investigated and compared between Chlorella vulgaris cultures with pH adjusted to 6.8 non-adjusted where raised above 10. Bisphenols a high partition coefficient (log P > 6) partitioned biomass soon after spiking, whereas low < 4) remained largely in the aqueous phase. Hydrophobic BPF isomers were removed lar...

Combustion of the municipal waste generates highly corrosive gases (HCl, SO2, NaCl, KCl and heavy metals chlorides) and ashes containing alkaline chlorides and sulphates. Currently, corrosion phenomena are particularly observed on superheater’s tubes. Corrosion rates depend mainly on installation design, operating conditions i.e. gas and steam temperature and velocity of the flue gas containing...
