  • Wastewater treatment plant effluent as a source of microplastics: review of the fate, chemical interactions and potential risks to aquatic organisms

    Wastewater treatment plant (WWTP) effluent has been identified as a potential source of microplastics in the aquatic environment. Microplastics have recently been detected in wastewater effluent in Western Europe, Russia and the USA. As there are only a handful of studies on microplastics in wastewater, it is difficult to accurately determine the contribution of wastewater effluent as a source ...

  • Quality and quantity survey of hospital wastewaters in hormozgan province

    Nowadays in many societies, access to healthy water and the amount of water consumption are considered as aspects of sanitation situation and development of societies. The consumed water in daily life is recycled to primary source in some ways, but it is in the form of a liquid containing the consumed water and different contaminants that are entered during consumption. One of the important ...

  • Why is mining wastewater treatment necessary?

    During Industrial processes and mining, there are certain discharges of environmental pollution. This outcome is the growing concerns about the living atmosphere. As per the increasing concerns of contamination, there should be a lot of efforts and implementation to save the environment from its hazardous effects. ...

  • Impact of ozonation in removing organic micro-pollutants in primary and secondary municipal wastewater: effect of process parameters

    The study investigates the influence of process parameters on the effectiveness of ozonation in the removal of organic micro-pollutants from wastewater. Primary and secondary municipal wastewater containing phenol was treated. The effect of operating parameters such as initial pH, ozone dosage, and initial contaminant concentration was studied. An increase in contaminant decomposition with pH ...

  • Biological treatment of toluene contaminated wastewater by Alcaligenese faecalis in an extractive membrane bioreactor; experiments and modeling

    Conventional wastewater treatment methods are not efficient in treating wastewaters contaminated with volatile hydrocarbons such as benzene, toluene and xylenes (BTX). The aim of this study is to enhance the efficiency of an extractive membrane bioreactor (EMBR) in treating toluene contaminated wastewater by usage of pure culture of Alcaligenese faecalis. Toluene was used as a model of toxic ...

  • How Do You Know If An Industrial Facility Needs a Wastewater Treatment System?

    Not properly treating wastewater can potentially harm the environment, human health, and a facility’s process or products (especially if the wastewater is being reused). It can also cause a company to incur heavy fines and possible legal action if wastewater is being improperly discharged into a POTW (publicly owned treatment works) or to the environment (usually under a National Pollutant ...

  • Screening of organic pollutants in urban wastewater treatment plants and corresponding receiving waters

    There is a lack of knowledge in environmental pollution of the anthropogenic contaminants in wastewater and surface water. Several organic compounds merit special attention, because of their potential risk to the aquatic environment. Therefore, gas chromatography–mass spectrometry-based screening analyses were performed in order to identify anthropogenic organic contaminants and to reveal ...

  • Water cleaning and wetland construction

    Slippery Rock University's Macoskey Center for Sustainable Systems has served as an ideal locale for the study of biological waste and wastewater concerns in Western Pennsylvania. The Center's constructed ponds, waterless composting toilet and indoor greywater treatment system produced, in 19982000, great amounts of data on ecological approaches to wastewater treatment, which need to be reviewed. ...

  • Scientific And Regulatory Perspectives On The Emerging Environmental Contaminants Issue

    ABSTRACTEmerging environmental contaminants include a wide variety of chemicals that have been largely outside of the scope of environmental regulation.  Also referred to as PPCPs (pharmaceuticals and personal care products), these contaminants are derived from any product consumed by humans or animals for health or cosmetic reasons, and thus include prescription and non-prescription human ...

  • Labile, dissolved and particulate PAHs and trace metals in wastewater: passive sampling, occurrence, partitioning in treatment plants

    The occurrence and the partitioning of polycyclic aromatic hydrocarbons (PAHs) and seven metals (Al, Cd, Cr, Cu, Ni, Pb and Zn) were investigated in activated sludge wastewater treatment plants by means of passive and active sampling. Concentrations total dissolved and particulate contaminants were determined in wastewater at several points across the treatment system by means of grab sampling. ...

  • Safe drinking water and waterborne outbreaks

    The present work compiles a review on drinking waterborne outbreaks, with the perspective of production and distribution of microbiologically safe water, during 2000–2014. The outbreaks are categorised in raw water contamination, treatment deficiencies and distribution network failure. The main causes for contamination were: for groundwater, intrusion of animal faeces or wastewater due to ...
