Hydrofluoric acid is used in large volumes during solar panels manufacturing for cleaning purpose. It results the generation of wastewater containing high concentrations fluoride. Chemical precipitation commonly to remove most fluoride from wastewater. reduces concentration ~ 20 mg/L, whereas discharge standard set 2 mg/L. Adsorption preferable when dealing with diluted This study evaluated ads...

The conventional sludge disposal options include landfill, application to farmland and forestry and incineration. However, since in the last decade sewage sludge and industrial sludge are being generated in increasing amounts due to the rapid urbanization and industrialization, a growing interest has been devoted in developing cost effective and renewable disposal alternatives. Among them, the ...

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 increasing consumption of phenoxyacetic acid-derived herbicides is becoming a major public health and environmental concern, posing serious challenge to existing conventional water treatment systems. Among the various physicochemical biological purification processes, adsorption considered one most efficient popular techniques due its high removal efficiency, ease operation, cost effectiven...
