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 ...

Background and aims: The removing of (potential) toxic heavy metal ions from sewage, especially in industrial and mining waste effluents, has been widely studied in recent years. The aim of present study was to investigate the various methods for lead removal of lead ions from industrial wastewater. Methods: This study was a review research. Data were collected through different databases in va...

A range of wastewaters and substrates were examined using mini microbial electrolysis cells (mini MECs) to see if they could be used to predict the performance of larger-scale cube MECs. COD removals and coulombic efficiencies corresponded well between the two reactor designs for individual samples, with 66-92% of COD removed for all samples. Current generation was consistent between the reacto...

In the context of urban drainage, the protection of surface waters from the effects of wastewater discharges has assumed increasing importance. As a result of human activity, there is sometimes contamination of water resources due not only to the phenomenon of diffuse pollution, but also as a result of specific effluent discharges (such as those from different industries or farming and by some ...

The lack of fresh water is one of the major threats for people. The extremely sufficient and cost saving methods for water and wastewater treatment must be applied. The paper shows possibility of using traditional Dissolved Air Flotation method (DAF) with alternation of feeding gas by ozone (Dissolved Ozone Flotation – DOF) instead of air to obtain better treatment results and possibilities of ...

introduction: due to the risks of hormones on human health and aquatic life, the aims of this study were to determine the efficiency of estrogen removal in the different stages of shiraz wastewater treatment plant using activated sludge process and marvdasht wastewater treatment plant using aerated lagoons process and also comparing the performance of both systems in removing the hormone of est...

stormwater represents one of the least researched forms of wastewater in environmental science. contaminated industrial stormwater, that is stormwater generated by runoff from industrial sites such as refineries, smelters and mine sites, is even less well understood. however, contaminated industrial stormwater can have damaging environmental impacts because it generally occurs in sudden bursts ...
