This paper addresses the issue of polishing electroplating wastewater in subsurface vertical flow constructed wetland. Electroplating wastewater treatment or polishing in constructed wetlands (CWs) was studied to a very limited degree. Four types of microcosm upflow constructed wetlands were selected for the experiment based on type of bed media and the presence or absence of vegetation (Phragm...

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 ...

The application of synthetic colors in textile industries and their entry into the water and groundwater is an environmental problem because of being very toxic material. The synthetic colors which are used in textile dyeing (plyacrilic and polyester) are usually dispersing colorants. They derive the azo and anthraquinone chemicals. Electro-Fenton process is an efficient technique which can deg...

background and purpose:moving bed biofilm reactor is an aerobic attached growth with better biofilm thickness control, lack of plugging and lower head loss. consequently, this system is greatly used by different wastewater treatment plants. high tds wastewater produced petrochemical, leather tanning, sea food processing, cannery, pickling and dairy industries. the aim of this study was to evalu...

In this study, a bioelectrochemical reactor was investigated for simultaneous hydrogen production and ammonium recovery from reject water, which is an ammonium-rich side-stream produced from sludge treatment processes at wastewater treatment plants. In the anode chamber of the reactor, microorganisms converted organic material into electrical current. The electrical current was used to generate...

Coagulation-flocculation followed by sedimentation and filtration is the most commonly used water treatment process , in which turbidity or particles removal is strongly dependent on proper coagulant dosage, effect of pH ,effect of time, jar test and settling column tests were perform. In the method the seeds were treated with different solvents of NaCl and NaOH to extract the active coagulant ...

background lead is a toxic metal with a poor electrical conductivity. this metal can be hazardous and poisonous even in low concentrations. objectives the objective of this study is the evaluation of prosopis mimosaceae sawdust as a low-cost adsorbent for removal of the lead from effluents. materials and methods the experiment was conducted in a batch system and the effect of ph, the amount of ...

The present investigation assesses the application of ceric sulfate for the removal of the colorant reactive blue19 (R.B19) from synthetic wastewater. The adsorption characteristics and dye removal efficiency of adsorbent have been determined by investigating factors such as effect of pH (pHOptimum

Background and purpose:Moving Bed Biofilm Reactor is an aerobic attached growth with better biofilm thickness control, lack of plugging and lower head loss. Consequently, this system is greatly used by different wastewater treatment plants. High TDS wastewater produced petrochemical, leather tanning, sea food processing, cannery, pickling and dairy industries. The aim of this study was to evalu...
