  • Removal of Microorganisms from Domestic Greywater Using a Recycling Vertical Flow Constructed Wetland (RVFCW)

    ABSTRACTThe reuse of greywater (GW) is an attractive addition to water management options. One of the major concerns limiting GW reuse is the possible presence of harmful microorganisms. In addition to total coliform organisms, enteric organisms (Salmonella, Shigella and poliovirus Type 1 Cryptosporidium, Giardia) and opportunistic pathogens ( Staphylococcus aureus and Pseudomonas aeruginosa) may ...

  • Material selection for a constructed wetroof receiving pre-treated high strength domestic wastewater

    A constructed wetroof (CWR) is defined in this study as the combination of a green roof and a constructed wetland: a shallow wastewater treatment system placed on the roof of a building. The foremost challenge of such CWRs, and the main aim of this investigation, is the selection of an appropriate matrix capable of assuring the required hydraulic retention time, the long-term stability and the ...

  • Rapid small-scale column testing of granular activated carbon for organic micro-pollutant removal in treated domestic wastewater

    This study investigates the applicability of the rapid small-scale column test (RSSCT) concept for testing of granular activated carbon (GAC) for organic micro-pollutants (OMPs) removal from wastewater treatment plant (WWTP) effluent. The chosen experimental setup was checked using pure water, WWTP effluent, different GAC products, and variable hydrodynamic conditions with different flow ...

  • Number of residual thermotolerant coliforms on plants and in soil when using reclaimed domestic wastewater for irrigation

    The reclamation of domestic wastewater for irrigation is one alternative approach to solve the water scarcity crisis, but it is essential to control the microbiological quality of wastewater used for irrigation. The removal of thermotolerant coliforms, also known as faecal coliforms (FC), from treated domestic wastewater by intermittent media infiltration (IMI) in column was studied. The columns ...

  • An examination of factors affecting sustainability of domestic rainwater harvesting systems in a rural, semi-arid region of Mexico

    Rainwater harvesting (RWH) is increasingly utilized today by populations to alleviate water supply issues, particularly in rural, dry environments. Limited research has considered, simultaneously, the numerous factors that contribute to sustainability – for example, social acceptance, water quality, and maintenance needs – of RWH. This research aimed to improve the understanding of factors ...

  • Comparison of metal (Zn and Cu) complexation characteristics of DOM in urban runoff, domestic wastewater and secondary effluent

    This study was aimed at comparing the Zn and Cu binding parameters with dissolved organic matter (DOM) in road runoff, wastewater treatment plant (WWTP) effluent and influent. Conditional stability constant (K′) and binding site concentration ([L]) are important to predict free or labile metal concentration and toxicity in the water environment. The values of K′ and [L] of three ...

  • Wastewater Treatment Plant

    Water is basic to life. It is a precious resource and has become precious commodity now. On going Industrialization, population & urbanization pose pressure on water availability. Utility value of world’s freshwater resources like lakes and rivers are diminishing rapidly due to over exploitation & pollution. Groundwater, an alternative to surface water is also a natural ...

  • Manganese waste water treatment by fungi derived from manganese slag

    The aim of this study was to isolate a mould from the surface of manganese slag which had strong resistance and high adsorption of Mn2 + , and to determine the effects of initial Mn2 +  concentration, incubation temperature, rotation speed and inoculation amount on adsorption of Mn2 +  from manganese waste water solution. The result showed that a mould (A5) which was isolated from manganese slag ...

  • Ozzi Kleen India Trade Mission - Waste water treatment

    India faces a desperate water shortage as water resources are depleting while the demands for water are rapidly rising. The Indian waste water industry provides a huge opportunity for innovative technologies and is estimated to be worth approximately USD 420 million and growing 18% every year. In June 2011 Ozzi Kleen joined a Water and Waste water Mission to India facilitated by Trade & ...

  • Wastewater Treatment for the Mining Industry

    Sustainable wastewater technologies minimize mining’s environmental footprint Mining for some minerals, including coal, has been diminishing due to increased financial, social, and environmental pressures, both in the United States and abroad. At the same time, mining for lithium and other metals — used in energy storage for electric cars, and wind and solar generation — is ...

  • The biological basis of wastewater treatment

    Introduction This booklet was written to fulfil the need for a simple explanation of the biological processes that underpin wastewater treatment. It attempts to show how the bacteria involved deal with the organic carbon in the sewage. Remarkably, there are just 3 major processes involved, and these mirror exactly the 3 major processes at work in the plant viz: biodegradation, oxygen ...

  • Wastewater Treatment in Sri Lanka

    JaEla and Ratmalana wastewater treatment. Recently Colombo National Water Supply & Drainage Board decided to collect and treat the combined (industrial and domestic) wastewater at both areas before it is being discharged into the receiving waters. New sewer systems and two wastewater treatment plants will therefore be constructed. The target treatment plant sizes are 82,000 ...

  • What Is Industrial Wastewater Treatment?

    Industrial progress has helped economic and social growth to a large extent, whereas, it has also created the major problem of environmental pollution at the same time as well. Industrial pollution is one of the major concerns of industries and environment protection agencies worldwide. The technical advantages have assisted the industries to reduce water pollution to a certain level. ...

  • What is biological wastewater treatment?

    Biological wastewater treatment harnesses the action of bacteria and other microorganisms to clean water Biological wastewater treatment is a process that seems simple on the surface since it uses natural processes to help with the decomposition of organic substances, but in fact, it’s a complex, not completely understood process at the intersection of biology and ...
