Since most industrial wastewaters contain phenol compounds, achieving eco-friendly and economic processes for filtration of such is one the concerns environmental researchers.Thus, present study aims to determine efficiency bio-filter activated sludge (BF/AS) combined process in removal from aqueous solution.In this experimental study, BF/AS reactor a pilot scale with continuous flow useful volume 24 L, made Plexiglas was utilized.Effect dissolved oxygen concentration, hydraulic residence...
Disposing wastewater from textile industries and dyes into water bodies has aesthetic effects on the nature of water, it can also cause serious adverse environmental impacts ecosystem by reducing sunlight penetration photosynthetic reactions. Adsorption is one most common methods for removal toxic pollutants due to its easy cheap operation. Using agricultural waste prepare simple adsorbents an alternative method commercial carbons. In this research, a cost-effective adsorbent was fabricated...
Waterpipe tobacco wastes (WTWs) may contain considerable levels of hazardous contaminants such as BTEX (benzene, toluene, ethylbenzene, o-xylene, and m/p-xylene). However, no research has been carried out on in WTWs the release these pollutants into water environment. This examined flavored/local also rate toxins three kinds water, including seawater (SW), tap (TW), distilled (DW) with different leaching times (15, 30 min, 1.2, 4, 8 h, 1, 2, 4 days). The mean contents WTW samples Al-Mahmoud,...
In this research, a total of 51 road dust samples were collected from three districts (Asaluyeh, Bushehr, and Goshoui) in the south Iran April to June 2022 analyzed for concentration 7 phthalic acid esters (PAEs) compounds. Asaluyeh was considered as an industrial area (near gas petrochemical industries), Bushehr urban area, Goshoui rural (far pollution sources). The PAEs street determined using mass detection chromatography (GC/MS). mean ± SD levels ƩPAEs industrial, urban, sources 56.9...
It has been documented that arsenic a potential risk to human health and identified as factor for hearing impairment. However, there are few studies confirm the ototoxic effect of arsenic, especially on auditory system. Therefore, current study was conducted investigate correlation between thresholds at different frequencies (0.25, 0.5, 1, 2, 4 8 kHz) levels in drinking water samples. A total 240 people, divided into two equal groups: exposed reference, were selected tests. should be noted...
The present work aimed to study the removal efficiency of Reactive Blue 222 (RB222) from aqueous solutions by applying a combined process with magnetic sodium alginate beads/H 2 O . effect various operating parameters including dosage, H concentration, pH, and dye concentration on was investigated. Freundlich Langmuir isotherms were used explain adsorption process. Adsorption kinetics RB222 beads also investigated using pseudo‐first‐, second‐order, intra‐particle diffusion kinetic models....
This study evaluated the relationship between arsenic uptake via drinking water ingestion and concentration in fingernails as a biomarker for human exposure. For this purpose, we collected fingernail samples from 40 healthy participants of arsenic-affected rural regions Kaboudrahang County, west Iran. A total 49 were also individuals who lived areas where contamination sources with had not been reported. It was found that contents 50 4.08% arsenic-contaminated reference villages higher than...
Detergents are considered one of the important pollutants in hospital wastewater. Achieving efficient and bio-friendly methods for removal these is as a concern environmental researchers. This study aims at studying efficiency moving bed biofilm reactor (MBBR) system removing linear alkyl benzene sulfonate (LAS) from wastewater with utilization response surface methodology (RSM). The present was carried out on continuous hydraulic flow using media k1 pilot scale to remove detergent effect...
The present work investigated the efficiency of nickel oxide nanoparticle (NiO) activated hydrogen peroxide (H 2 O ) in presence ultraviolet (UV) irradiation degrading cephalexin (CLX) from aqueous solutions.The effect pH solution (3-9), NiO dosage (1.5-2 mg/L), concentration (5-20 ml/L), contact time (10-60 min) and CLX initial (20-80 mg/L) was studied optimized using Taguchi design.The percentage contribution each operational parameter on degradation determined analysis variance.The...
Polyvinyl alcohol (PVA) is one of the refractory chemicals that widely used in several industries as raw material and may be released into receiving waters through unsanitary disposal different wastewaters.This compound considered a hard biodegradable resistant harmful to human health.Its presence water resources causes disturbance deposition removal heavy metals formation foam treatment processes.Therefore, current research, for first time, we investigated performances Mn 3 O 4 /H 2 , K 5...
