background: olive oil wastewater  contains chemical contents and organic materials that are resistant to biodegradation.  the existence of phenolic inhibitor compounds, toxicity to microorganisms in wastewater treatment units, unpleasant odor, high biochemical oxygen demand (bod) and chemical oxygen demand (cod), high suspended solids, and compounds resistant to biodegradation in such wastewate...

a lab-scale sbr equipped with a flat sheet membrane in submerged configuration that is named msbr was used for the treatment of composting leachate. it was fed by biologically treated leachate with overall 70-1360 mg/l chemical oxygen demand (cod). the values of ph, electrical conductivity (ec), and dissolved oxygen (do) were monitored routinely. however, analysis of total cod, soluble cod (sco...

In this study, the treatability of rose processing wastewater was investigated by using electrocoagulation (EC) methods compared to classical chemical (CC) and Fenton application (FA) processes. High chemical oxygen demand (COD) and dissolved solids contents were detected in the wastewater. Among these treatment applications, it was found that the EC unit is the most effective treatment techniq...

Textile wastewater contains substantial pollution loads in terms of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) and heavy metals. Phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (AMATS) is well established environmental protective technique. A lab scale stud...

A bioreactor equipped with hollow fiber microfiltration membranes was applied for wastewater treatment. Removal of chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) was investigated. The experimental setup consisted of influent and effluent tanks, and membrane modules using Polyvinyl Di–Fluoride (PVDF) hollow fibers. The operation program included suction and backwash...

background: wastewater produced by a dairy in sanandaj is a major source of environmental pollution threatening the city. the dairy uses activated sludge treatment to remove organic pollution from the wastewater. the present study evaluated the performance of this process and its compliance with national requirements for chemical oxygen demand (cod), biochemical oxygen demand (bod), and total s...

A membraneless bioelectrochemical system - rotatable bio-electrochemical contactor (RBEC) consists of an array of rotatable electrode disks was developed to convert the chemical energy from wastewater organics (acetate) directly into electricity. Each rotatable electrode disk had an upper-air exposing and a lower-water submerging halves. Intermittent rotation (180°) enabled each halve to altern...

In any type of rubber product manufacturing (including tires), the primary concerns are environmental. The aim of the present study was to survey a treatment combination of ozonation and physicochemical processes in the rubber industry. Wastewater samples were collected from the discharge unit of the rubber processing sewage system in Kerman Barez Tire Factory, Kerman, Iran. The wastewater samp...
