  • Ozone-based reclamation of an STP effluent

    The system ozone and hydrogen peroxide was used to reclaim wastewater from the secondary clarifier from a Sewage Treatment Plant (STP) of Alcalá de Henares (Madrid-Spain). The assays were performed by bubbling a gas mixture of oxygen and ozone, with ~24 g Nm-3 of ozone concentration, through a volume of wastewater samples for 20 minutes at 25°C . The removal of dissolved ...

  • Advanced treatment of Membrane Bioreactor (MBR) effluents for effective wastewater reclamation

    One of the two main objectives of this work is to oxidize MBR effluents with ozone/peroxide in high pH conditions in order to improve oxidation of pharmaceuticals, which could efficiently be rejected by the nanofiltration (NF) stage. The other main objective is to effectively oxidize of dissolved organic carbon (DOC) in MBR effluents in order to decrease fouling in the filtration stage. In this ...

  • Potential for wastewater reclamation and reuse in Lebanon

    Eleven major wastewater treatment plants are planned for construction along the sea coast of Lebanon to handle the flow from the major urban centres. The plants are expected to generate approximately 640,000 m3 of treated sewage daily, and the effluent is planned to be disposed into the sea. In the light of the water deficiency that the country would be facing in the coming years, the reuse ...

  • Agricultural re-use & reclamation of treated effluents: The experience of the Thessaloniki Wastewater Treatment Plant (Thessaloniki, Greece)

    Greece is located in Southern Europe. Lying along the shores of the Aegean, Ionian and Mediterranean seas, it thus has a very long coastline. Its terrain consists mainly of mountain and hill country and Greece is, in fact, one of the most mountainous countries in Europe. The climate is typically Mediterranean, featuring mild wet winters and hot dry summers. ...

  • Comparison of RO and NF in wastewater reclamation

    Currently, water reuse and reclamation are considered as an essential technology available for alternative water resources with respect to non-potable as well as potable uses. Therefore, lots of studies have been developing various technologies for water reuse, reclamation, and desalination to producing the more reliable and higher quality reclaimed/reused water. In addition, there are several ...

  • Dumping of the effluent of Punjab in Sindh

    The province of Punjab has been blessed with immense quantity of fresh groundwater. On the contrary, the quality of groundwater in the province of Sindh is mainly saline. There are very few pockets in Punjab where the quality of groundwater is saline. The commands of Punjnand Abbasia Canal and Fordwah Sadqia Canal, on the let bank of River Sutlej, are one of those pockets, which are underlain ...


  • Occurrence and removal of Giardia and Cryptosporidium at the Goreangab reclamation plant

    This paper deals with the occurrence of Giardia and Cryptosporidium in the water sources available for the Goreangab Reclamation Plant (GRP) and the subsequent removal during treatment at the reclamation plant. Giardia is detected more often than Cryptosporidium. 60% of the time it is detected in the samples from the dam and in 55% of the samples from the maturation pond effluent. During the ...

  • Effluent to Energy and It Is Renewable

    The Systems Conveyance and Operations Program (SCOP), located in Clark County, Nevada, will enable the Clean Water Coalition (CWC) to improve the water quality of Lake Mead, the main water source for the Las Vegas Valley, and to meet the increasing water demands of its four member agencies: the City of Las Vegas (CLV), the Clark County Water Reclamation District (CCWRD), the City of Henderson ...

  • Case study - Daphne utilities water reclamation facility

    With significant TSS and BOD reductions from their Salsnes Filter system, Daphne Utilities has restored previously lost plant capacity. More than that, loading reductions have cut back aerator maintenance and lowered energy consumption of blowers. Project Background Daphne Utilities, situated on the eastern shore of Mobile Bay in Alabama, provides water, sewer and natural ...

  • An evaluation of MBR and conventional pretreatment for reverse osmosis for water reclamation

    Two wastewater polishing systems were compared in terms of their ability to protect downstream reverse osmosis (RO) processes. A conventional full-scale wastewater treatment system with primary and secondary treatment followed by rotating biological contactors (RBC) and sand filtration were compared in a side-by-side study with a pilot-scale membrane bioreactor (MBR). Effluent from the two ...

  • Development and testing of a low sludge discharge membrane bioreactor for greywater reclamation

    A low sludge discharge membrane bioreactor (LSDMBR) for greywater reclamation was developed and tested in this study. LSDMBR was designed by combining an aerobic activated sludge process with an immersed membrane filtration process. LSDMBR offers the following advantages over conventional activated sludge processes. Firstly, LSDMBR has a high biomass concentration attributed to membrane ...

  • Color removal and disinfection with UV/H2O2 system for wastewater reclamation and reuse

    ABSTRACTReuse of wastewater effluents from secondary treatment processes in municipal wastewater treatment plants has been issued because of substantial volumes of relatively clean waters. The major components of criteria for wastewater reclamations are color, organic matter, and pathogens. An advanced oxidation process with low-pressure ultraviolet and hydrogen peroxide addition ...

  • Wastewater reclamation and reuse in Europe: a model-based potential estimation

    ABSTRACTThe basic aim of this paper is to present an approach to quantitatively assess the potential of municipal wastewater reclamation and reuse in a European context. The model developed is based on the analysis and interrelation of water management data like water availability, water demand and treated effluent. In conjunction with information about the current status of wastewater reuse ...

  • Removal and relationships of microbial indicators in a water treatment and reclamation facility

    A wastewater treatment and reclamation facility in north-east Spain was monitored over 1 year to determine the occurrence and concentrations of different microbial indicators (Escherichia coli, fecal enterococci, somatic bacteriophages and spores of sulfite-reducing clostridia). The removal of the indicators and its relationships through the wastewater treatment and reclamation trains were ...

  • Reuse and recycling of secondary effluents in refineries employing advanced multi-barrier systems

    In this paper the reclamation and reuse of municipal secondary effluents, as well as the reclamation and recycling of refinery secondary effluents, are technically and economically evaluated. It is shown that both practices are feasible and sustainable, and that the reclamation costs depend largely on specific circumstances such as legal requirements, price policy, reuse application, raw water ...
