“…The most widely used isotherm models are linear [26], Freundlich [27] and Langmuir [28]. These models are as follows: (11) where Ce is the concentration of solute in solution at equilibrium time (mg cm −3 ), x is the amount of absorbed solute (mg l −1 ) and m is the mass of absorbent (g).…”

“…Also the special framework structures of zeolite consist of interconnected channels and cages that are occupied by the cation of valence and water molecules. The most important characteristics of the zeolite are the ability to exchange the cations located at specific sites in the channel and cage systems for various cations from solution [11]. Whereas, these materials have high absorption capacity and can hold some cations in their porous network, they can play the role of nutrition and improve plant growth and have been recommended to be used for wastewater treatment [12].…”

“…Typically, in arid countries such as Saudi Arabia, where there are limited water resources, high concentrations of NO 3 ([180 mg L -1 ) emanating from nitrogen fertilizers and sewage seepage have restricted groundwater use for drinking purposes (Loni et al 2014;Metwaly et al 2014). Furthermore, high NO 3 content ([200 mg L -1 ) in industrial wastewater (Aly et al 2014) poses a treatment challenge. It is therefore imperative to protect water resources by applying a suitable treatment technology for NO 3 removal.…”

Biochar has emerged as a universal sorbent for the removal of contaminants from water and soil. However, its efficiency is lower than that of commercially available sorbents. Engineering biochar by chemical modification may improve its sorption efficiency. In this study, conocarpus green waste was chemically modified with magnesium and iron oxides and then subjected to thermal pyrolysis to produce biochar. These chemically modified biochars were tested for NO3 removal efficiency from aqueous solutions in batch sorption isothermal and kinetic experiments. The results revealed that MgO-biochar outperformed other biochars with a maximum NO3 sorption capacity of 45.36 mmol kg(-1) predicted by the Langmuir sorption model. The kinetics data were well described by the Type 1 pseudo-second-order model, indicating chemisorption as the dominating mechanism of NO3 sorption onto biochars. Greater efficiency of MgO-biochar was related to its high specific surface area (391.8 m(2) g(-1)) and formation of strong ionic complexes with NO3. At an initial pH of 2, more than 89 % NO3 removal efficiency was observed for all of the biochars. We conclude that chemical modification can alter the surface chemistry of biochar, thereby leading to enhanced sorption capacity compared with simple biochar.

Organik madde, askıda katı madde, yağ ve gres içerikleri oldukça Characteristics of Olive Oil Wastewater, Its Environmental Effects and Treatment Technologies AbstractOlive oil manufacturing wastewater is a serious environmental problem in the Mediterranean regions due to several factors such as seasonal production, distribution over large areas of mills, high organic load. Amount and pollutant load of this wastewater changes depending production process used and operational conditions. Organic matter, suspended solid matter, oil and grease contents of this wastewater are quite high. Treatment of olive oil wastewaters becomes difficult due to high organic matter, seasonal
