Recreational and potable water supplies polluted with human wastewater can pose a direct health risk to humans. Therefore, sensitive detection of human fecal pollution in environmental waters is very important to water quality authorities around the globe. Microbial source tracking (MST) utilizes human fecal markers (HFMs) to detect human wastewater pollution in environmental waters. The concen...

This research focused on the biological treatment of high-strength organic nitrogen wastewater, and presented the results from the nitrification and denitrification of an actual industrial wastewater using anoxic/aerobic process. The opto-electronic industrial wastewater often contains a significant quantity of organic nitrogen compounds and has a ratio over 95% in organic nitrogen (Org-N) to t...

Swine wastewater is characterized by high organic matter content, solids, nitrogen (expressed as total ammonia and protein) and heavy metals. This work determines the methanogenic toxicity effect of free ammonia contained in swine wastewater comparing raw swine wastewater (RW) and the liquid fraction of swine wastewater (TW). The values of IC50 (50% of inhibition) obtained for methanogenic bact...

Some physical, chemical and biological properties of raw water collected from Caroni River in Central Trinidad and raw wastewater from Angostura Distillery in North Trinidad were measured in the laboratory. In addition, the properties of the water effluent obtained by passing the raw Caroni River water through various sand-clay filter media that differed in the proportions of sand and clay by v...

BACKGROUND Purified terephthalic acid (PTA) wastewater from a petrochemical complex was utilized as a fuel in the anode of a microbial fuel cell (MFC). Effects of two important parameters including different dilutions of the PTA wastewater and pH on the performance of the MFC were investigated. METHODS The MFC used was a membrane-less single chamber consisted of a stainless steel mesh as anod...

article as: Deng L, et a ation Process, Biosystem The performance of an Anaerobic-Adding Raw Wastewater-Intermittent Aeration (ANARWIA) process was investigated in a full-scale plant. After 1 year’s operation, a successful treatment for swine wastewater had been developed, without adding alkali or external organic matter. The anaerobic unit can maintain chemical oxygen demand (COD) removal effi...

background: aminoglycoside antibiotics are widely used in medical centers, particularly to treat infections. the resistance developed against these agents is a huge concern in health care. a number of researchers have reported that hospital and municipal wastewaters are among the most important dissemination sources of these agent into the environment. some, however, do not agree with this opin...
