Globally, investigation for alternative sustainable and renewable energy sources to fossil fuels is increasing day by day. In energy production, non-fossil and CO2 neutral raw materials should be mostly used. Biomass could be used for this purpose. Waste biomass formed as a result of agricultural and industrial activities can be used as fuel or ads...

In this study, aluminum, iron, calcium and magnesium existing in thermal power plant fly ash were leached by the method of hydrochloric acid with 20% acetic acid. Then, solvent extraction and precipitation methods were applied for recovery processes. The effects of acid concentration, reaction time, and temperature on leaching of iron, aluminum, ca...

Ülkemizde termik santrallerden kaynaklı uçucu küller depolanmaktadır ve depolanan küller yüksek oranda metal içeriğine sahiptir. Uçucu küller ile ilgili yapılan çalışmalar genellikle liç çalışmaları ya da uçucu külün inşaat sektöründe veya diğer endüstri kollarında kullanımı üzerinedir. Yapılan çalışmalar irdelendiğinde, mevcut termik santrallerden...

Termik santrallerde oluşan uçucu küllerin büyük bir kısmı kül barajlarına akıtılarak depolanmaktadır. Depolanan küllerin içeriğinde bulunan metal/ağır metal miktarları oldukça fazla olup, çevresel risk oluşturmaktadır. Uçucu küllerle ilgili çalışmalar daha çok tarımsal alanlarda, inşaat sektöründe ve diğer endüstri kollarında kullanımı üzerinedir....

Mesophilic biomass and thermophilic biomass samples were isolated and used to remove Dorasyn Red dye from aqueous solutions. The biosorption kinetics of dye uptake by four different types of biomass at three temperatures (20, 30, and 40 °C) were investigated using pseudo-first order kinetics, pseudo-second order kinetics, intraparticle diffusion, E...

This paper investigates the removal of iron and zinc from aqueous solution with dairy wastewater in three different biomasses such as Lactobacillus delbrueckii ssp bulgaricus (Lb-12), Streptococcus thermophillus (STM-7) and a combination of both this bacteria culture (YC-380) and the optimization of removal efficiency using MINITAB program. A full...

Struvite precipitate obtained from yeast industry anaerobic effluent with high ammonium nitrogen (NH4-N) was investigated for fertilizer effect on plant growth and nutrition according to applications of N, nitrogen/phosphorus/potassium (NPK), and control. Optimum struvite formation conditions were determined via Box-Behnken design. Optimum conditio...

The main purpose of this study was to investigate the effectiveness of Lactobacillus 12 and Lactobacillus rhamnosus as both cells and biomasses for the removal of dye from real textile dyeing wastewater. The removal experiments were conducted according to the Box-Behnken experimental design, and the regression equations for the removal of dye were...

The main objective of this work was to investigate the effectiveness of ceramic ultrafiltration (UF) membranes with different pore sizes in removing natural organic matter (NOM) from model solutions and drinking water sources. A lab-scale, cross-flow ceramic membrane test unit was used in all experiments. Two different single-channel tubular cerami...

The main objective of this study was to investigate the effects of reductive acidic leaching and further precipitation on the recovery of manganese and zinc from spent alkaline and zinc-carbon battery powders. Ascorbic acid (AA), citric acid (CA) and oxalic acid (OA) were tested as the reductants. Sodium hydroxide and potassium hydroxide were used...

The main purpose of this work was to investigate the effectiveness of oxalic acid as a reductant for the leaching of manganese and zinc from spent alkaline and zinc–carbon batteries in sulfuric acid or hydrochloric acid media. Three different types of battery powders were tested: zinc–carbon, alkaline and mixed (50% zinc–carbon, 50% alkaline). Kine...

The main aim of this paper is to review and evaluate the recovery studies and associated technologies for metals from spent batteries. More attention was given especially to the recovery of Zn and Mn from spent alkaline and zinc–carbon batteries. Nowadays much research work is concentrated on the recovery of Zn and Mn from alkaline and zinc–carbon...

The main objective of this work was to determine the effectiveness and kinetics of hydrogen peroxide in destroying cyanide in the tailings slurry from a gold mine with low sulphide and heavy metal content. The impacts of catalyst (Cu) and hydrogen peroxide concentrations, temperature and pH on the extent and rate of weak acid dissociable (WAD) cyan...
