Many industrial processes and sewage treatment facilities produce odours, most of which are of decomposed sulphur compounds. Hydrogen sulphide (H2S), which is a very toxic and corrosive gas, may be the standard indicator among the obnoxious odours and therefore the amount released into the air is required to be regulated strictly. Hydrogen sulphide was efficiently removed from contaminated air by a pilot-scale bio-filter; a column prepared with soil, sawdust and activated sludge materials from the leather industry...

It is well known that, many kinds of industrial organic waste can be used for biogas production, but the biogas and methane yields depend on the biodegrability of the compounds in raw material. Recent studies are aimed to increase the biodegradability of organic matter by many pretreatment processes. In this study, belt-filter press sludge which has been taken from the waste water treatment plant of ETAP, has been used in experiments, basic and/or microwave radiation (MW) pretreatments have been carried out in ord...

Heavy metals in wastewater are quite important because of being toxic effect for public health. Wastewaters that contain heavy metals are generally caused by industries discharged, either after primary treatment or even no-treatment farmers in Konya use wastewater for irrigation that discharged into canal. This causes soil pollution also decreases plant quality. Heavy metals can reach to humans and animals and causes toxic effects through food-chain. The aim of this study is determining heavy metal accumulation on...

We took into consideration aspects regarding the physiology at two species of wooden angiosperms cultivated in sites from industrial area of Borzesti, Bacau District: Populus tremula L. and Tilia tomentosa Moench., during their ontogenetic cycle. We also talked about aspects related to some special biochemical and physiological parameters (dry matter content and assimilating pigments content). The researches of vegetal physiology have used classical methods of investigation. The negative influence of air pollutant...
