This book was released on 2010 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater from industry can lead to water pollution if untreated, especially due to its high concentration of heavy metals. Heavy metals are considered extremely harmful because they can cause illnesses, disorder and diseases to human. Therefore, industrial wastewater containing heavy metal should be treated before discharge to the water stream but its treatment is very costly. There are several techniques to remove heavy metals from wastewater such as biosorption, filtration and adsorption of heavy metal but there is some limitation such as long treatment time. This research is about the efficiency of combination method between ultrasonic and adsorption process to remove zinc, Zn and nickel, Ni from fertilizer factory wastewater. The parameters analyzed in this research are amounts of adsorbent in solutions from 0.5 g to 2.9 g of tea waste, different ultrasonic temperature from 40° C to 80° C and different sonication time from 5 minute to 29 minutes. After several experiment and analysis of results, it is found that the optimum condition to remove Zn and Ni from 100 ml wastewater is at 24 minute sonication time and 75°C ultrasonic temperature for 2.5 g amount of adsorbent which can remove about 79% of zinc and 71% of nickel. According to the result, the method of ultrasonic assisted by adsorption process to remove heavy metal from industrial wastewater can be use effectively because it can reduce energy, time and cost of treatment.

This book was released on 2012-01-10 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides public health, sanitary and water engineers baseline data for designing plants for the treatment of industrial effluents rich in the metallic species in general and that of nickel and chromium in particular. DescriptionWater pollution is a topic of immense and common concern throughout the world. With a rapidly escalating global population and increased industrial development in a growing number of countries, the world's freshwater resources have become stressed. One way to get more out of less is 'treatment and reuse'. Nickel and chromium are toxic metals and they are used extensively in numerous industries such as textiles, beverages, steel, pulp and paper, and electroplating. Their industrial effluent contains large measures of non-biodegradable traces that are harmful to flora, fauna, and human beings. Although there are a number of methodologies used for treatment of metal-containing industrial effluents and waste water, there is not one up to now that offers a high capacity removal rate at an economical cost. This book presents the results and data from research and adsorption experiments carried out on the removal of nickel and chromium (as well as other metals) from aqueous solutions using modified silica sand. The data resulting from detailed kinetic, equilibrium and thermodynamic studies, show that the removal capacity is increased so the treated water has a higher quality or purity. It also demonstrates that the extraction of metals is achieved at a significant lower cost because the treated water adsorption is a simple process with less maintenance, and because silica is a nontoxic natural material widely available in all parts of the world.

Book Synopsis Metal Removal and Recovery from Mining Wastewater and E-waste Leachate by : Suthee Janyasuthiwong
Download or read book Metal Removal and Recovery from Mining Wastewater and E-waste Leachate written by Suthee Janyasuthiwong and published by CRC Press. This book was released on 2020-02-18 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal contamination in the environment is a persisting global issue. The metal reservoirs in the earth have declined due to society’s needs and due to uncontrolled mining activities. Therefore, the idea to recover metals from waste streams has emerged. In this thesis, cost competitive technologies such as adsorption using agro-wastes and precipitation using an inverse fluidized bed (IFB) reactor were investigated, with special emphasis on the recovery of base metals. Groundnut shell showed good potential for metal (Cu, Pb and Zn) removal. From artificial neural network modeling, the performance of the sulfate reducing bacteria (SRB) was found to be strongly pH dependent; the removal efficiency of Cu and Zn in the IFB at pH 5.0 was >97%. Electronic waste is a good candidate as secondary metal resource. The recovery of Cu from computer printed circuited boards (PCBs) using biogenic sulfide precipitation was investigated as well. Using this technology, Cu could be recovered at ~0.48 g Cu/g PCBs.
