Nitrification of waste waters from fish-meal factories
Fish-meal factories generate waste waters with high chemical oxygen demand (COD), suspended solids (SS), fats and protein concentrations. After their treatment by anaerobic digestion, effluents with high ammoniaand organic-nitrogen contents and a fraction of residual COD are produced. A biological nitrification/denitrification process is proposed to reduce both the residual carbon and the nitro...
متن کاملEstrogens in coastal waters. The sewage source.
Gynecologic case report 117 The vast majority of vaginal fungal infections are caused by Candida species, especially Candida albicans1,2. Recently, attention has focused on an unconfirmed increase in vaginal infections caused by C. glabrata3. Most microbiological investigations of large numbers of women with fungal vaginitis have reported infrequent symptomatic vaginitis caused by unusual speci...
متن کاملR-plasmid transfer in Salmonella spp. isolated from wastewater and sewage-contaminated surface waters.
A total of 865 Salmonella isolates from wastewaters and sewage-contaminated natural waters were tested for antimicrobial resistance by using NR10 medium and incubation at 43 degrees C. Of the strains, 12.7% were resistant to one or more of the compounds tested, and 30% transferred resistance to an Escherichia coli recipient. The highest minimal inhibitory concentrations were ca. 1,000 microgram...
متن کاملMicro-TLC Approach for Fast Screening of Environmental Samples Derived from Surface and Sewage Waters
In this work we demonstrated analytical capability of micro-planar (micro-TLC) technique comprising one and two-dimensional (2D) separation modes to generate fingerprints of environmental samples originated from sewage and ecosystems waters. We showed that elaborated separation and detection protocols are complementary to previously invented HPLC method based on temperature-dependent inclusion ...
متن کاملReconcentration of poliovirus from sewage.
Virus can be adsorbed from effluents of sewage treatment plants on large-surface membranes. Subsequent elution of virus requires large volumes, which in turn requires reconcentration of virus for assay. However, reconcentration of such viral eluates on small adsorbent surfaces is difficult because certain soluble sewage components are adsorbed along with the virus on the initial virus adsorbent...
