Degradation of Estrogens in Sewage Treatment Processes

Different Approach to Anaerobic Sewage Treatment Processes

INTRODUCTION Anaerobic technology have been successful applied for industrial waste water treatment. High reaction rate per unit volume by retaining the biomass in the reactor independently of the incoming waste water flow and concentration. Often high volumetric loading rates in the order of 10 to 40 kg COD/m.d are used. High rate anaerobic biological reactors may be classified into three broa...

Flow Characteristics of the Raw Sewage for the Design of Sewage-Source Heat Pump Systems

The flow characteristics of raw sewage directly affect the technical and economic performance of sewage-source heat pump systems. The purpose of this research is to characterize the flow characteristics of sewage by experimental means. A sophisticated and flexible experimental apparatus was designed and constructed. Then the flow characteristics of the raw sewage were studied through laboratori...

Pneumoproteins in sewage workers exposed to sewage dust

PURPOSE The association between exposure to bacteria and endotoxins in sewage dust and the serum concentrations of pneumoproteins in sewage treatment plant workers were studied. METHODS Forty-four workers from eight sewage treatment plants and 38 reference workers participated in the study. Microbial aerosol was collected by personal inhalable samplers. The concentrations of bacteria and endo...

Surfers against sewage.

We describe a web server for the accurate mapping of experimental tags in serial analysis of gene expression (SAGE). The core of the server relies on a database of genomic virtual tags built by a recently described method that attempts to reduce the amount of ambiguous assignments for those tags that are not unique in the genome. The method provides a complete annotation of potential virtual SA...
