Background and Objectives: Dyes are an important class of pollutants, which can even be identified by naked eye. Disposal of dyes in precious water resources have been prohibited, however, various treatment technologies are in use. Among various methods adsorption occupies a prominent place in dye removal. Therefore, natural zeolite (clinoptilolite) and acid modified zeolite were used as a low...

A physicochemical study for the treatment of pharmaceutical wastewater was performed. Objective of the laboratory investigation was to study the removal of color, Total Dissolved Solids (TDS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), turbidity and phenol and bring them up to the allowable limits for reuse purposes. Efficiency of coagulation, flocculation, sedimentation, sa...

Degradation of humic substances in water is important due to its adverse effects on the environment and human health. The aim of this study was modeling and investigating the degradation of humic substances in water using immobilized ZnO as a catalyst. ZnO nanoparticles were synthesized through simple coprecipitation (CPT) method and immobilized on glass plates. The immobilized ZnO nanocatalyst...

Bromide which is present in many water resources has the potential to create adverse health effects after water disinfection by oxidizing agents, and it is considered to be the most important mineral in this respect. Bromide removal is not feasible in conventional water treatment plants. This survey with the aim of removing Br" from water has been accomplished by performing pilot tests in which...

The study examined the effects of pulsed electric field treatment on kinetics and properties convective-dried mushrooms using different drying agents. Increasing air temperature reduced time, while use dehumidified resulted in faster water removal. PEF treatment, depending parameters, shortened time maximum by 12% or extended time. physical (dry matter content, rehydration properties, hygroscop...

Background: Conventional chemical coagulation is considered as the old method to color and COD removal in textile effluent. Electrocoagulation (EC) process is a robust method to achieve maximum removal. Methods: This work was designed to compare the result of operational parameters including optimum pH and coagulant concentration for chemical coagulation with ferric chloride and alum. Also, th...
