Drying of spruce, beech, willow, and alder sawdust was examined in a laboratory type dryer. The effect drying air temperature T (25, 60, 80 °C) airflow velocity v (0.01, 0.15, 1.5 m/s) investigated. obtained results demonstrated that have impacts on the sawdust. experimental dehydration data were fitted to theoretical, semi-theoretical, empirical thin-layer models. accuracies models estimated u...

In the brewing industry, spent brewery grains (SBGs) are byproducts with a low economic value. The potential use of this leftover as a substrate ingredient for Pleurotus ostreatus fruiting body cultivation and enzyme production was evaluated. The best substrate mixture for P. ostreatus mycelium growth comprised 30% wheat bran (WB), 68% beech sawdust (BS) and 2% CaCO3. On the substrates containi...

Spruce sawdust (lignocellulose material) was magnetically modified after contact with a water-based magnetic fluid containing maghemite nanoparticles. This procedure allows one to use the prepared material as a new magnetic affinity adsorbent in magnetic separation techniques. The magnetic sawdust was investigated by means of electron spin resonance spectroscopy and conventional magnetic method...

The survival of two hygienically relevant bacteria, Escherichia coli pIE639 and Enterococcus faecium, was followed on wooden sawdust of seven different European woods (pine, spruce, larch, beech, maple, poplar, and oak) versus polyethylene chips by using cultivationdependent and molecular-based methods in parallel. The survival of the bacteria on wood was dependent on various factors such as th...

Application of nitrogen fertilizers to reach high crop production is common practice. However, this has a environmental cost, irrespectively the synthetic or organic origin fertilizer. In particular, intensively managed arable soils often fail retain excess nitrogen, which leads contamination ground- and surface water. Next abiotic factors like soil texture, limited retention ascribed low activ...

In this paper, application of sawdust prepared from Narra wood (SD) modified with cationic surfactant of cetyltrimethylammonium bromide (SD/CTAB) was used for removal of two typical acid dyes commercially named as Acid Green 25 (AG25) and Acid Red 14 (AR14) from aqueous solutions. The effects of experimental variables, such as pH, initial dye concentration, adsorbent dose, contact time and temp...
