Organic pollutants have an adverse effect on the neighboring environment. Industrial activates are the major sources of different organic pollutants. These primary pollutants react with surrounding and forms secondary pollutant, which persists for a long time. The present investigation has been carried out on the surface of activated sawdust for phenol eliminations. The process parameters initi...

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...

Vermicomposting is an established process to convert organic wastes into vermicastings suitable for plant growth. This research investigated the vermicomposting of anaerobic digestate with four different ratios of sawdust as a bulking material, for 75 days. The optimum proportion of anaerobic digestate to sawdust was identified as 70:30 based on worm growth and reproduction. Vermicomposting pro...

A multigeneration system based on solar thermal energy associated with hot and cold thermal storage is designed and analyzed energetically and exergetically. The system produces electricity, a heating effect, a cooling effect, hydrogen, and dry sawdust biomass as outputs by means of organic Rankine cycles, a heat pump, two absorption chillers, an electrolyser, and a belt dryer. The intermittent...

The sorption of copper ions onto natural bamboo sawdust with cellulose-lignin polymeric structure strongly depends on pH. The adsorption capacity for copper ions increases as increasing pH and copper loadings. The fitting of copper pH boundary curve by NEM surface complexation models shows that: three-sites model including the ion exchange reaction of permanent charge fits better than two-sites...

Adsorption behavior of chromium, Cr(VI) from wastewater has been investigated using clarified sludge (a steel plant waste material), rice husk ash and sawdust as non-conventional adsorbents. The studies were carried out at room temperature (30C) following batch adsorption technique in a reciprocating shaker. Factors affecting the adsorption characteristics such as agitation time, initial metal ...

This work examined the structural properties of concrete obtained bypartially replacing cement with sawdust ash. The ash which is apozzolan was by burning a waste product fromprocessing timber in an open air. burnt passed through a150 µm metric sieve to obtain used. Physical and chemical analysiswere performed on verify its suitability as partial substitute forcement concrete. Chemical analysis...
