  • Treatment of cyanide wastewater by bulk liquid membrane using tricaprylamine as a carrier

    The transport of cyanide from wastewater through a bulk liquid membrane (BLM) containing tricaprylamine (TOA) as a carrier was studied. The effect of cyanide concentration in the feed solution, TOA concentration in the organic phase, the stirring speed, NaOH concentration in the stripping solution and temperature on cyanide transport was determined through BLM. Mass transfer of cyanide through ...

  • Factors Affecting Cyanide Generation in Chlorinated Wastewater Effluent Matrix

    ABSTRACTFalse positives for cyanide analysis in wastewaters have been reported. We examined the effects of storage time at high pH and of pH adjustments on the cyanide levels. Cyanide levels changed within the holding time allowed by Standard Methods. We also studied the difference in cyanide levels using two disinfection conditions -- breakpoint chlorination and chloramination. Glycine was used ...

  • Study of cyanide wastewater treatment by dispersion supported liquid membrane using trioctylamine and kerosene as liquid membrane

    A certain amount of cyanide is present in wastewater of various industrial processes, such as wet extraction of gold, coal processing, electroplating and other industries. In this work, an experimental study regarding transport of cyanide through a dispersion supported liquid membrane was performed. A model was established to describe the reaction and transport of CN(I) in the supported liquid ...

  • Why buy a Colorimeter

    Cyanide in your Juice? Mercury in your chicken soup? Your well water seems a little brown? Your wine causes you to pucker? There is a way to test for unknowns in solutions, waters and fluids. A colorimeter used to interpret the absorbance and/or transmittance of light entering a fluid, may be the way. ...

  • On line analysis of organic in water case study

    Introduction On line chemical analysis has been developed significantly thanks to digital electronics' use of microprocessors together with the application of sophisticated and accurate analytical techniques. The result of this combination is readily available technology which allows for on line performance of almost any analytical determination for quality control which is ...

  • Ensuring Water Quality in Africa

    Water is essential for life, and “access to safe water is a fundamental human and, therefore, a basic human right.” With this statement and his address on World Water Day in 2001, United Nations Secretary-General Kofi Annan put a spotlight on what continues to be a global problem: clean water. This year completes the UN “Water for Life” international decade for ...

  • Water infrastructure security against Al Qaeda`s revenge for the death of Bin Laden

    On May 2, 2011, the United States (U.S.) President Barack Obama announced that the U.S. forces killed Osama Bin Laden, the world's most dangerous terrorist leader that killed approximately 3000 Americans on September 11, 2011 (9/11) terror attacks. Currently, the U.S. intelligence is in possession of valuable materials of Al Qaeda operations (Thomas, 2011). Terrorist attack plots include water ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • Toxicity Identification Evaluation (TIE) as a Tool for Water Quality Management

    Whole effluent toxicity (WET) testing has evolved into a critical element of many National Pollutant Discharge Elimination System (NPDES) permits issued to both industrial and municipal dischargers. Over 6,500 dischargers to both fresh and salt waters are required to conduct toxicity tests to determine if their effluent might be potentially toxic to organisms in the receiving system. While ...
