Dye-containing wastewater is one of the main environmental challenges that can cause health issues. It is crucial to remove the dyes from wastewater before its discharge into the environment. This study aims to evaluate the efficiency of aptenia cordifolia mucilage in removal of anionic dyes from textile wastewater via coagulation and flocculation process. To this goal, the effect of different ...

Microplastics (MPs), sized ~150 μm, have been found in tap water at levels of ~5 particles/L, suggesting that treatment plants are not effectively removing MPs. Therefore, there is an urgent need to evaluate their fate drinking processes. Coagulation-flocculation and sedimentation applied primarily decrease turbidity, MPs contribute turbidity. This study focuses on the removal polystyrene (PS) ...

Introduction: Textile wastewaters from dyeing and finishing processes are heavily polluted with dyes, textile auxiliaries and chemicals and have a broad range of pH, high COD concentration and suspended particles. In this study, the efficiency of color and turbidity removal from synthetic textile wastewater samples were investigated by combined process of coagulation/ flocculation and electron ...

Membrane filtration is one of the alternatives suggested for the future drinking water production. Worldwide, the total number of ceramic membrane usage for water treatment is increasing swiftly and this is the first ceramic filtration study which is applied to a surface water treatment in a tropical region. This study was conducted to investigate the removals of natural organic matter and path...

The main aim of this work was to study the removal efficiency of Pb from synthetic and industrial wastewaters by using biomass fly ashes. The biomass fly ashes were produced in a biomass boiler of a pulp and paper industry. Three concentrations of Pb(2+) were tested in the synthetic wastewater (1, 10 and 1000 mg Pb/L). Moreover, two different wastewaters were collected in an industrial wastewat...

A physicochemical treatment (coagulation-flocculation) was applied to a slaughterhouse wastewater, using anionic polyacrylamide as coagulant aid to improve the settling velocity of the flocs formed with the coagulants used: ferric sulphate, aluminium sulphate and polyaluminium chloride. The optimum speed and stirring time for the flocculation stage were ascertained along with the optimum pH and...

A coagulation–microfiltration (MF) system has the potential to remove natural organic matter and mitigate membrane fouling. The effect of flocculation conditions on MF performance was investigated using three membrane modules including stirred cell, dead-end MF, and submerged MF. The experimental results were analysed in terms of filterability, particle size, and floc structure as represented b...
