conclusions to solve the above mentioned difficulties, fundamental study most be carried out to discover the novel methods of ferrate(vi) production, focusing on increasing the product stability and the production yield. results despite the existence of these technologies, there is no full-scale application of ferrate(vi) in the water and wastewater industry which it is due to difficulties asso...

background: selection of different wastewater treatment methods depends on the kind of wastewater, geographical position of the community, quantity and quality of wastewater and effluent, technology and finance. natural wastewater treatment methods are simple, cheap and acceptable for developing countries specially small and remote countries and wetland is one of these methods. wetlands include...

the presence of pharmaceutical compounds in the environment and waste streams has received lots of attention in recent years due to its adverse effects on the health of different organism. the emerging of these compounds in the environment is a growing concern and recent researches have focused on finding new ways for enhancing the pharmaceutical compound’s removal efficiency in the effluent of...

In the relentless pursuit of Moore’s Law, Intel’s Technology Development cycle results in a new semiconductor production process every two years. As this continuous cycle of new products moves from conception to market, so do the innovative environmental solutions designed to meet Intel’s philosophy of environmental excellence. Intel’s success in design-forenvironment (DFE) is widely recognized...

BACKGROUND High salinity (1-10% w/v) of tannery wastewater makes it difficult to be treated by conventional biological treatment. Salt tolerant microbes can adapt to these saline conditions and degrade the organics in saline wastewater. RESULTS Four salt tolerant bacterial strains isolated from marine and tannery saline wastewater samples were identified as Pseudomonas aeruginosa, Bacillus fl...

Membrane aerated biofilms (MABs) are an emerging technology for wastewater treatment. Several bench scale and pilot scale studies have help to highlight the benefits of this technology. This paper will discuss experiments that examined the impact of oxygen gradients and the impact of BOD gradients on the performance of MABs, and discusses how an MAB compares to a conventional biofilm.

Membrane Bioreactors (MBRs) can be broadly defined as systems integrating biological degradation of waste products with membrane filtration. They have proven quite effective in removing organic and inorganic contaminants as well as biological entities from wastewater. Advantages of the MBR include good control of biological activity, high quality effluent free of bacteria and pathogens, smaller...

Discharge of domestic and industrial wastewater to surface or groundwater is very dangerous to the environment. Therefore treatment of any kind of wastewater to produce effluent with good quality is necessary. In this regard choosing an effective treatment system is important. Sequencing batch reactor is a modification of activated sludge process which has been successfully used to treat munici...

BACKGROUND Biofilm-based microalgal growth was determined as functions of organic chemical loading and water temperature utilizing dairy wastewater from a full-scale dairy farm. The dairy industry is a significant source of wastewater worldwide that could provide an inexpensive and nutrient rich feedstock for the cultivation of algae biomass for use in downstream processing of animal feed and a...
