In this study, biochar (BC) derived from slow pyrolysis of spruce sawdust and activated BC with HNO3 were used as sorbents to remove methylene blue (MB) dye the aqueous solution. was prepared by at temperatures 200, 300, 400, 500 °C. Based on screening results, two BCs (BC 400 °C °C) exhibiting a higher percentage removal selected investigate further effect factors, including contact times 15, ...

Density-independent high moisture content measurement is required in actual production line. In this paper, the experimental results for high moisture content measurement using microwave free-space technique are presented. The method is based on a ratio of phase shifts at two microwave frequencies after propagating through a sample. The experiments were performed with three kinds of sawdust nam...

Abstract Wastewater containing dyes are released into water bodies generating serious problems in human health and marine life. To contribute to the solution of this problem, a novel activated carbon was prepared from untreated pine ( Pinus radiata ) sawdust by dry chemical activation with ZnCl 2 used for wood dye adsorption. The characterized point zero charge, N CO adsorption isotherms, SEM-E...

An experiment was conducted to study the effects of different soil media on seed germination and seedling growth of peach during 2001 and 2002 in Orakzai Agency. Different soil media alone and in combination used for seed germination of peach were Farm Yard Manure, Saw dust, Canal silt, FYM + Sawdust, FYM + Canal silt, Sawdust + Silt and FYM + Sawdust +Silt. Different media showed non significa...

The research comprised of studying the effect composting sewage sludge with sawdust and vermicomposting with earthworm Eisenia fetida has on the degradation of 16 polycyclic aromatic hydrocarbons (PAHs). Raw rural sewage sludge prior composting was more contaminated with PAHs than urban sewage sludge, in both cases exceeding EU cutoff limits of 6 mg/kg established for land application. Dibenzo[...
