Removing Fe, Zn and Mn from steel making plant wastewater using RO and NF membranes
Background and purpose: Excessive amount of heavy metals in industrial wastewater is a seriously crucial issue and requires efficient methods to be introduced and dealt with. Meanwhile, steel making plants as productive units in every country release large amounts of fluid into surface and underground sources. Typically, this wastewater contains heavy metals in minor amounts, while this amount ...
متن کاملRemoval of Mn, Fe, Ni and Cu Ions from Wastewater Using Cow Bone Charcoal
Cow bone charcoal (CBC) was synthesized and used for the removal of metals ions (manganese, iron, nickel and copper) from aqueous solutions. Two different adsorption models were used for analyzing the data. Adsorption capacities were determined: copper ions exhibit the greatest adsorption on cow bone charcoal because of their size and pH conditions. Adsorption capacity varies as a function of p...
متن کاملmapping of available fe, zn, cu and mn in soils of southern tehran lands by geostatistical and gis techniques
this study was conducted to determine the spatial variability and mapping of available micronutrients iron, zinc, copper and manganese on 20,000 hectares of soils in south of tehran lands in order to identify deficiency, enough and toxicity areas. 196 surface soil samples (0-25cm) to a regular grid network of 1000×1000m were collected and extracted by dtpa and tea and concentrations of elements...
متن کاملAdsorption of heavy metals (Cu, Mn, Fe and Ni) from surface water using Oreochromis niloticus scales
Surface water contains a large number of pollutants, particularly human pathogens, organic toxicants and heavy metals. Due to the toxic nature of heavy metals towards marine organisms, its removal from the environment has been a growing issue. The biosorption of heavy metal ions from surface water using fish scales has emerged as an environmentally friendly technique. This study assessed the de...
