Precious metal refining from ore or electronic devices includes hydrometallurgical processes with major concern about toxicity wastewater production. As an alternative, one-step electroleaching-electrochemical deposition process (EL-ECD) using ionic liquid mixtures was evaluated for palladium and gold recovery. A halide based combined a diluting chosen among ten electrolytes after cyclic voltam...

collection and reuse of wastewater and sewage in agriculture, natural resources and green environment is one way to conserve water resources and environmental. the aim of this study were to investigate the effects of wastewater sirjan golgohar industrial on the characteristics of cultivated soils in several species of pasture trees. this study was performed at the sirjan city which is located i...

The volume of wastewater generated by domestic, industrial, and commercial sources has increased with population, urbanization, improved living conditions, and economic development. The productive use of wastewater has also increased, as millions of small-scale farmers in urban and periurban areas of developing countries depend on wastewater or wastewater-polluted water sources to irrigate high...

the isolated fungi species of different kinds from chromium contaminated soil sites located in nagalkeni, chennai were used for reducing chromium(vi) in a tannery industry wastewater of nagalkeni, chennai.  the experiments were conducted to know biosorption potential of isolated fungi species for removing chromium(vi) in a tannery industry wastewater against the different ph, fungi biomass and ...

The impact of untreated and partially treated domestic wastewater on rivers and community water sources continues to raise health and safety concerns. The organisms of concern in domestic wastewater include enteric bacteria, viruses, and protozoan cysts. Table 1 summarizes the most common microorganisms found in domestic wastewater and the types of human diseases associated with them. Based on ...

In recent years, irrigating agricultural land with wastewater has become a major wastewater management practice. Irrigation has replaced much of the discharge to streams and conventional primary and secondary waste treatment for food processing wastewater (4, 11, 12, 13). Irrigating agricultural land for treatment and disposal of the food processing wastewater is a good practice if the wastewat...

This paper presents a case study on application of photosynthetic bacteria wastewater treatment system to recover organic carbon in wastewater in the form of photosynthetic bacterial cells. In noodle production process, the wastewater was mainly produced during rice soaking and rinsing processes containing starch as its main constituent. For carbon recovery purpose, wastewater was applied to la...
