Optimization of degradation of ciprofloxacin antibiotic and assessment of degradation products using full factorial experimental design by Fenton Homogenous process
Water and Wastewater Treatment
The Pharmaceutical contaminants specialist antibiotics into environment can create problems for both human health and environment. Ciprofloxacin (CIP), an antibiotic Fluoroquinolones group, has recently been used widely for infections treatment. The main purpose of the research was to develop a Full...
Role of Microorganisms in Permeable Reactive Bio-Barriers (PRBBs) for Environmental Clean-Up: A Review
Water and Wastewater Treatment
It is an indisputable fact that any environmental clean-up technology generating certain kind of effective result would be easily supported. One of them includes Permeable reactive bio-barrier which is an innovative technology started from 90’s to treat a variety of contaminants along the natural...
Adsorption of Remazol Brillant Green 6B (RBG 6B) on chitin: process optimization using response surface methodology
Water and Wastewater Treatment
In the present study, the adsorption of Remazol Brillant Green 6B (RBG 6B) on chitin which characterized by BET, FTIR, XRD and SEM analysis was studied. Response surface methodology (RSM) was applied to determine interaction between solution pH, initial RBG 6B concentration and chitin dosage being...
Acid and Ultrasound Assisted Modification of Boron Enrichment Process Waste and Using for Methylene Blue Removal from Aqueous Solutions
Water and Wastewater Treatment
In this study, raw boron enrichment waste was treated with hydrochloric acid and ultrasound at 35-kHz frequency for 60 minutes. To optimize the adsorption conditions for removal of methylene blue (MB) from synthetic wastewaters using raw boron enrichment waste (BEW), acid modified boron enrichment...
Use of photocatalysis for conversion of harvested rainwater as an alternative source into drinking water
Water and Wastewater Treatment
The aim of this study is to investigate the performance of solar photo-catalyst of titanium oxide (TiO2/Solar) process to treat rainwater. The polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs) in rainwater were chosen to be investigated in this study. The rainwater...
Assessment of heavy metal pollution in sediments and their bioaccumulation in phragmites australis frome Nil river (Jijel- Algeria)
Environmental Sciences
The content of heavy metals in sediment and the aquatic plant Phragmites australis (roots and leaves), collected from six different stations along the Nil river, were determined providing information about heavy metals pollution status of this aquatic ecosystem. The results showed that the abundance...
Inorganic carbon removal from refinery wastewater by using TiO2/ZnO/Fenton photocatalyst
Wastewater treatment
The aim of this study is to investigate the performance of the solar photocatalyst of TiO2/ZnO/Fenton process to treat the refinery wastewater and remove inorganic carbon (IC) which potentially toxic to human, aquatic and microorganism life. Central composite design with response surface methodology...
A study of alkali-activated concrete mixes with ground granulated blast furnace slag
General
The paper presents a laboratory study of concrete mixes based on the alkali-activation of an industrial by-product, ground granulated blast furnace slag (GGBS). A number of factors potentially affecting the resulting concrete quality in terms of workability and strengths were investigated (namely...
Adsorption of cadmium and copper onto natural clay: isotherm, kinetic and thermodynamic studies
Water and Wastewater Treatment
Clay of the Middle Atlas Mountains region, Morocco, was used to investigate the removal of heavy metals ions (Cadmium and Copper) from aqueous solutions with respect to several experimental conditions including pH, contact time, initial solute concentrations, temperature and ionic strength. Kinetic...
The distribution and variability of heavy metals in a mountainous fir forest ecosystem in two hydrological years
Environmental Sciences
The concentrations (for two hydrological years) of the heavy metals As, Cd, Cr, Ni and Pb as well as the isotopic 206Pb/207Pb composition in soil layers were studied in a remote mountainous Bulgarian fir (Abies borisii regis) forest in central Greece. The concentrations of metals in the hydrological...
