Scrubbers are widely used for air pollution treatment in semiconductor. Efficiency of waste gas must be carefully maintained environmental and health issue. However, due to the complex types exhaust system needs using chemicals with different characteristics at same time semiconductor process, many conditions will occur operation scrubber tower processing efficiency reduced. This paper aims com...

Abstract This study investigated the anaerobic digestion of an algal–bacterial biofilm grown in artificial wastewater Algal Turf Scrubber (ATS). The ATS system was located a greenhouse (50°54?19?N, 6°24?55?E, Germany) and exposed to seasonal conditions during experiment period. methane (CH 4 ) potential untreated (UAB) thermally pretreated (PAB) using different microbial inocula determined by b...

Our society generates extensive amounts of municipal solid waste (MSW), which are mainly incinerated for volume reduction and energy recovery. Though, MSW incineration hazardous air pollution control (APC) residues that must be treated deposited in appropriate landfills. An alternative to landfilling is material recovery, leading regeneration valuable products reducing amounts. The chemical com...

A full-scale biodrying installation was treating 150 kton (wet weight) of dewatered waste activated sludge per year. The waste was treated at thermophilic conditions (65-75 °C) in a 2-step forced aeration process reducing the total wet sludge weight by 73%. The final product had a high caloric value (7700-10,400 (kJ/kg)), allowing a combustion for energy generation in external facilities. The r...

A haloalkaline anaerobic microbial community obtained from soda lake sediments was used to inoculate anaerobic reactors for the production of methane rich biogas. The microalga Spirulina was successfully digested by the haloalkaline microbial consortium at alkaline conditions (pH 10, 2.0 M Na(+)). Continuous biogas production was observed and the obtained biogas was rich in methane, up to 96%. ...
