FLUID MECHANISM IN AN AIR-LIFT DRAFT TUBE TYPE SEWAGE TREATMENT REACTOR

Epicoccum nigrum and Cladosporium sp. for the treatment of oily effluent in an air-lift reactor

The metalworking industry is responsible for one of the most complex and difficult to handle oily effluents. These effluents consist of cutting fluids, which provide refrigeration and purification of metallic pieces in the machining system. When these effluents are biologically treated, is important to do this with autochthonous microorganisms; the use of these microorganisms (bioaugmentation) ...

Sanitary Sewage Lift Stations

The lift station is becoming increasingly common as a component of the sewerage systems of Indiana. Cities and towns that have operated for years without the necessity of a lift station (other than one integral with sewage treatment plant) are finding it necessary to include a lift station in plans for extension of sewers. Those cities and towns which have not yet found it necessary to include ...

Copper Recovery from Chalcopyrite Concentrate by an Indigenous Acidithiobacillus ferrooxidans in an Air-Lift Bioreactor

In this study, effects of solid concentration, temperature, and initial Fe2+ concentration on bioleaching of sulfide mineral (chalcopyrite) obtained from Sarcheshmeh Copper Mine in the region of Kerman located in the south of Iran were investigated. A mesophilic iron oxidizing bacterium, Acidithiobacillus ferrooxidans has been isolated from a typical chalcopyrite copper concentra...

Domestic sewage treatment in a sequencing batch biofilm reactor (SBBR) with an intelligent controlling system

Poultry Slaughterhouse Wastewater Treatment Using Anaerobic Fluid Bed Reactor and Aerobic Mobile-Bed Biological Reactor

This research evaluated the efficiency of combined anaerobic-aerobic processes for the treatment of slaughterhouse wastewater. The anaerobic reactor consists of a 3.95 L Plexiglas column with 60 mm diameter and 140 cm height. The cylindrical particles of polyvinyl chloride with 2 mm diameter and 1250 kg m-3 density packed to 60 cm of column were used as biomass saving material. The d...
