New method for reducing ventilation cost through optimized air circulation in Green Houses

The numerical presented results are about the turbulent airflow over a typical pitched-roof agricultural structure. The airflow simulation is based on the solution of the Navier-Stokes equations and continuous equation with the finite element method. Taking into account the proper boundary condition...

Removal of Pollutants from Poor Quality Coals by Pyrolysis

Aiming to meet the recently adopted strict environmental standards, and the need of affordable in cost clean power production, a preventive fuels pre-treatment technique, based on low temperature carbonization, has been tested. Clean coals were produced from two poor quality Greek coals and an Austr...

Leaching and Toxicity Behavior of Coal–Biomass Waste Cocombustion Ashes

The leachability of trace elements from lignite, biomass, and blends cocombustion ashes was investigated by using the Toxicity Characteristic Leaching Procedure (TCLP) of the US Environmental Protection Agency (US EPA). In this work, the toxicity of the aqueous leachates and the concentrations of th...

Production of special activated carbon from lignite for environmental purposes

A treatment technique involving three sequential stages (demineralisation, activation and sulphur dispersion) was developed for the production of suitable activated carbons. Demineralisation included three steps of acid treatment and samples received were characterised by X-ray diffraction (XRD). A ...

Thermal exploitation of wastewood with lignite for energy production

Blends of natural wood, demolition wood, railroad sleepers, medium-density fiberboard residues, and power poles with lignite were used, and the co-combustion efficiency and the effect of wastewood addition on the emitted pollutants were investigated. Carbon monoxide, sulfur dioxide, and oxides of ni...

AquAsZero, Development and industrial exploitation of a Fe-Mn adsorbent for simultaneous removal of As(III) and As(V) from potable water

It is believed and proved through our experimental research that Mn causes oxidation of As(III) to As(V) which is less toxic and more efficiently adsorbed by the Fe hydroxides . The work refers to the development and the industrial scale production of a low-cost granular adsorbent called AquAsZero c...
