Wastewater treatment

The future of southern Italian regions lays mainly on conservation and recovery of their peculiar environment (i.e., pleasant climate, beautiful nature and historic heritage). Presently, most of such regions have to face major problems related to water shortage for agriculture and, in some cases, ev

WHO published in 1989 the first Guidelines for the Safe Use of Wastewater and Excreta in Agriculture and Aquaculture that were widely used. Since that time, more experience has been gained and more evidence is produced. The new WHO guidelines on water reuse in agriculture, recently published, provid

The city of Buenos Aires, the capital town of Argentina, is located besides De la Plata river, and is surrounded by a continuum of built areas, the so-called Greater Buenos Aires. The present situation of sewerage system is described and analysed taking into account: distance from Buenos Aires city,

Industries including a fermentation step use large volumes of water to dilute their musts. In beet alcohol distilleries, this water is recovered as condensates during stillage concentration. Because of their high organic content, these condensates cannot be discharged without a treatment. The elimin

Biological wastewater treatment plants (BWWTP) are widely used to treat effluents from chemical process industry. However, there exist refractory substances, such as phenolic compounds, which require previous treatments. Advanced oxidation processes (AOP) are thoroughly being studied as pre-treatmen

Urban wastewater treatment in small rural communities, where technical and financial resources are usually limited, can pose a problem. Experience has shown that, when treating wastewater in small communities, the solutions used in larger cities are not applicable. In order to solve the problems inv

To reuse pretreated water effluent of the El-Nile Company for the food industry in Egypt, NF and RO membrane separation techniques were investigated. Two sets of experiments were carried out by using laboratory separation unit with maximum pressure of 7 bars and pilot plant membrane separation unit

Different category-wastewater samples were collected from the inlets of biological treatment plants (installed in hospitals, industries and municipality) and from the body of polluted natural surface water (PNSW) systems (lakes, rivers). UV absorption spectral data of each wastewater system or their

Activated sludge bulking caused by filamentous bacteria Eikelboom type 021N and Thiothrix spp. is reported for the first time in a multistage pilot-scale wastewater treatment plant for enhanced biological phosphorus removal (EBPR). Both types of microorganisms grew gradually reaching their maximum c

Textile industry is one of the most common and essential sectors in the world. On the other hand, high volume of water consumption and varying wastewater characteristics due to many products such as dyes, biocides, carriers, detergents, etc. used in the process are the factors that have caused a con
