Produced water is the largest waste stream generated in oil and gas industries. The disposal of this hypersaline wastewaters containing a mixture of different organic and inorganic compounds is a relevant issue. In this study the removal of total suspended solids (TSS) from a real Produced Water, sampled at a full scale oil refinery plant, was optimized. Coagulation experiments were conducted s...

Hospital wastewater contains pathogenic agents and hazardous compounds; so, it will cause many risks on environmental and human health of different communities. The aim of this research was to investigate the efficiency of hospital wastewater treatment plant in north of Iran. This cross-sectional descriptive research was done on four hospital wastewater treatment plant in north of Iran during 2...

background: untreated leachate is being discharged into the environment in many countries worldwide. leachate treatment methods have not been unified so far due to the variable composition of leachate. moreover, the lack of appropriate treatment and disposal of leachate causes environmental pollution. this study aimed to compare removal efficiency of chemical oxygen demand (cod) and total suspe...

in this survey, with the main objective of studying final effluent treat ability of pars paper industries, the quantitative and qualitative characteristics of the effluent were firstly determined, which showed a min. and max. rate of 1350 and 1800 m3/hr, with 1400 mg/l and 839.5 mg/l respectively for cod and tss, as the main contaminants. also cod and tss population equivalents were calculated ...

in the present study, the treatment of tannery wastewater was performed by electrocoagulationmethod (ec) using aluminium and steel electrodes. response surface methodology (rsm) with three factors; current density (i), electrolysis time (t) and ph, with each factor at five levels, was used to optimize the factors for higher chemical oxygen demand (cod) and total suspended solids (tss) removal. ...

Th e aim of this study was to determine the chemical composition and antioxidants capacity of three plum cultivars, namely ‘Top’, ‘Elena’ and ‘Bistrica’. Fruits were harvested and following parameters were determined: dry matter, total acids (TA), total soluble solids (TSS), pH, vitamin C, total phenols, nonfl avonoids and antioxidant capacity. Diff erences between cultivars for most of the che...
