Water requirement to meet agriculture, domestic, industrial and other demands indicate the need for regeneration of waste water. Industrial waste water is being used in dry areas. Waste water of pulp and paper industry (brown with unpleasant smell) is usually alkaline in nature, has high suspended solids, total solids, COD, BOD and toxic odorous substances. It was observed in the study areas th...

This work is devoted to the investigation of discoloration synthetic and industrial effluent, using a quarry residue (MbP), which material naturally composed mixed oxides, compared zinc oxide (ZnO), acting as photocatalysts adsorbents. The optimization pH catalyst concentration parameters was carried out, effluent then treated by photocatalytic reactions, adsorption, photolysis. Industrial supp...

background: water resource management is a strategic issue in qom city. water scarcity is one of the most critical concerns of industrial estates. this study aimed to evaluate wastewater management in the shokuhieh industrial park of qom province in 2013. methods: this is a descriptive cross-sectional study done by visiting the industrial units in person, completing questionnaires and analyzing...

Water pollution caused by industrial effluent discharges has become an alarming trend worldwide, while textile industries are considered as the most polluting among all others. In recent years, bio-treatment took attraction in removing the unwanted colour and toxicity of textile effluents than other conventional treatment processes. The present study concentrates in the isolation and identifica...

this study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by azolla caroliniana.  the experimental investigations have been carried out using azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), ph (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). the maximum removal ...

Two bacterial strains were isolated from pharmaceutical effluents discharged soil. The samples were identified as Klebsiella pneumonia and Pseudomonas aeruginosa the biological degradation was carried on two bacterial isolates separately added to pharmaceutical effluent water. After proper interval were analysed the physic chemical parameters such as pH, Turbidity, Chemical oxygen demand (COD),...

Effectiveness of ozonation before and after biological treatment for removal of recalcitrant organic matter in bleached kraft pulp effluents was compared. Two industrial ECF bleached eucalypt kraft pulp effluents (E1 and E2) were pretreated with 100 mg O3/L. Raw and pretreated effluents were treated biologically in bench-scale sequencing batch reactors, under constant conditions. Following biol...

To study the extent of removal of Cu(II) ions from the electroplating industrial effluent, metal resistant fungal strain of Penicillium janthinellum was selected for the present study. Response surface methodology was used to optimize the sorption process variables i.e. temperature (20-40 oC), biomass concentration (0.5-2.5 mg/l), pH (2.0-6.0) and initial concentration of metal ions (20-100 mg/...

In this study, the effluent reuse potential of 39 industrial wastewater treatment plants (WWTPs) in Taiwan was evaluated using grey relation analysis. A significant, consistent result was revealed. The WWTPs with the lowest reuse potential among 39 industrial parks were in the order: Gueishan, Tucheng, Nankang WWTPs. The WWTPs with highest reuse potential were as follow: Yungan > Tafa > Fongsha...
