Abstract Decentralized wastewater plants have been proven to be cost-effective, easy construct and operate widely used in small ruler communities. The suitability of reclaimed for irrigation purpose was evaluated this study based on the various water quality parameters, international standards water–irrigation guideline (JS 1766). Twenty-seven samples were collected from a decentralized plant t...

The aim of this study was to evaluate the hygroscopicity and nanomechanics earlywood (EW) latewood (LW) larch after thermal modification under vacuum conditions. Wood samples were heat-treated in a atmosphere at 180–220 °C for 6 h, then their cell wall properties observed using dynamic water vapor sorption (DVS), imaging Fourier-transform infrared (FTIR) microscopy, nanoindentation. results sho...

BACKGROUND AND AIMS Only few data on the epicuticular waxes (EWs) of horsetails are available. This contribution therefore focuses on the wax micromorphology and chemical composition of Equisetum species of the subgenera Equisetum and Hippochaete. METHODOLOGY Distribution patterns and structural details of EW on the shoots were studied by scanning electron microscopy. After extraction with ch...

Groundwater is a major source of water for domestic, industrial, and agricultural sectors in many countries. The main objective of this research was to provide an overview of present groundwater quality using parameters such as calcium, magnesium, sodium, chloride, sulfate, pH, and electrical conductivity (EC) in the Mehran plain, Ilam province using GIS and geostatistical techniques. A total o...

This study aims to identify and determine species diversity and richness of the Gastropods of the intertidal zone of Bushehr seaport coastal area and assess the ecological status of this area using Welch index. Sampling was carried out at 6 stations in Bushehr seaport in the winter and summer seasons during 2013-2014. Bed sediment sampling was done three times in each station and Gastropod samp...

Introduction: Dyes have complicated structures, they are usually toxic and resistant to biological treatment and enter the environment through industrial waste streams. The aim of this study was to review the isotherm and kinetic adsorption studies of Reactive Blue 19 (RB19) dye onto Jujube stems powder from synthetic textile wastewater. Materials and Methods: This study was conducted in labo...

background: unsustainable development of human societies, especially in arid and semi-arid areas, is one of the most important environmental hazards that require preservation of groundwater resources, and permanent study of qualitative and quantitative changes through sampling. accordingly, this research attempts to assess and analyze the spatial variation of quantitative and qualitative indica...

This cross-sectional study was conducted on the drinking water resources of the city of Jolfa (East Azerbaijan province, Iran) from samples taken from 30 wells. Calcium hardness, pH, total alkalinity, TDS, temperature and other chemical parameters were measured using standard methods. The Langelier, Rayzner, Puckhorius and aggressive indices were calculated. The results showed that the Langelie...

Problems caused by dissolved organic matter (DOM) present in drinking water include its constituent compounds being precursors in the formation of disinfection by-products that pose risks to human health. The prediction of trihalomethanes (THM) formation is highly challenging due to a wide range of impacting factors, including the concentration and character of DOM, pH, temperature and the pres...

background: this study was carried out to determination of heavy metals (cd, cr, cu, fe, pb, ni and zn) concentration in upstream and downstream of the entry of the wastewater (untreated urban, traditional slaughterhouse waste, leachate from solid wastes has accumulated in river and  run off waters flowing across the city ) to the tembi river. methods: samples were collected for 1 year, before ...
