Synthetic dyes are among the most common contaminants of the environment. Therefore, the aim of this study was investigation the removal of Basic Blue 41 (BB41) and Methylene Blue (MB) from industrial effluents by useing raw and modified rice stems. In this study raw and modified rice stems treated chemically with Citric Acid (CA) and were used to explore the potentiality of rice stems for ...

The epidemiological data linking air pollution and lung cancer are derived from statistical associations concerning rates of cancer among urban and rural residents, migrant studies and studies of occupational groups exposed to effluents from fossil fuel combinations. Few, if any of these studies, are adequately adjusted for both relatively simple measures of cigarette smoking or the potentially...

Abstract The present study aims to fill the data gap analysis in urban wastewaters characteristics Benin and its statistical analysis. Physicochemical parameters such as pH, electrical conductivity (EC), Chemical Oxygen Demand (COD), Biochemical (BOD5), Total Kjeldahl Nitrogen (TKN), Phosphorus (TP) UV Absorbance at 254 nm, were determined on domestic (greywater blackwater) industrial (hospital...

The disposal of industri al eftluents is a problem of increasing importance throughout the world. In Indi a, a huge amount of waste water generated from distillery and paper industri es is discharged on land or into the running water. Di stillery waste water is characterized by low pH, hi gh BOD and COD values and contains a high percentage of organic and inorganic material s. This waste water ...

Nanofiltration (NF) has become a widely accepted process not only for producing drinking water but also for recovering wastewater in industrial processes or removing pollutants from industrial wastewater effluent. In the textile industry, the treatment of various dye baths with NF at room temperature have already been studied and was found feasible at lab-scale and pilot scale. The aim of this ...
