Wetlands are land areas that are wet during part or all of the year. Constructed wetlands are man-made systems that mimic the functions of natural wetlands applied for wastewater treatment. The aim of this research is to investigate the feasibility of using a constructed wetland for treatment of kitchen waste water from hostel mess. The wetland plant species grown in the constructed wetland is ...

Considerable effort is being expended to assess the effectiveness of urban Best Management Practices (BMP) for stormwater quality enhancement. The effectiveness of structural BMP’s is typically evaluated based on a limited amount of test data, which has lead some state organizations established programs requiring mandatory testing for these devices. One such program is the Technology Acceptance...

the aim of this study was the increasing of leachate quality using integrated membrane bioreactor (mbr). the reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (cod). the analysis of cod, biochemical oxygen demand (bod5), total suspended solids (tss), and total dissolved solids (tds) were performed in feed and filtrate, whenever the system reached steady stat...

Produced water is the largest waste stream generated in oil and gas industries. The disposal of this hypersaline wastewaters containing a mixture of different organic and inorganic compounds is a relevant issue. In this study the removal of total suspended solids (TSS) from a real Produced Water, sampled at a full scale oil refinery plant, was optimized. Coagulation experiments were conducted s...

Water quality monitoring through remote sensing with UAVs is best conducted using multispectral sensors; however, these sensors are expensive. We aimed to predict multispectral bands from a low-cost sensor (R, G, B bands) using artificial neural networks (ANN). We studied a lake located on the campus of Unisinos University, Brazil, using a low-cost sensor mounted on a UAV. Simultaneously, we co...

Sequencing batch reactor (SBR) technology has found many applications in industrial wastewater treatment in recent years. The aim of this study was to determine the optimal time for a cycle of the sequencing batch reactor (SBR) and evaluate the performance of a SBR for petrochemical wastewater treatment in that cycle time. The reactor was operated with a suspended biomass configuration under ae...

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...

Food-service establishments that use on-site wastewater treatment systems are experiencing pretreatment system and/or drain field hydraulic and/or organic overloading. This study included characterization of four wastewater parameters (five-day biochemical oxygen demand [BOD5]; total suspended solids [TSS]; food, oil, and grease [FOG]; and flow) from 28 restaurants located in Texas during June,...

The evaluation of a membrane bioreactor (MBR) for pretreatment of reverse osmosis (RO) in order to reuse and reclamation of industrial town wastewater treatment plant was investigated in this study. Performance of MBR effluent through water quality in term of parameters such as chemical oxygen demand (COD), total suspended solids (TSS), total nitrogen (TN) and total coliform (TC) were measured....
