  • 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 ...

  • Biological wastewater treatment followed by physicochemical treatment for the removal of fluorinated surfactants

    Perfluorinated surfactants (PFS) have become compounds of high concern during the last decade. While “conventional surfactants” are degraded to a great extent in the biological wastewater treatment process, partly or perfluorinated surfactants are not only stable against biodegradation but also against oxidizing agents, they even resist OH-radical attacks. Our objectives were to eliminate the ...

  • Biological treatment of ammonium perchlorate-contaminated wastewater: a review

    Absolute reduction of perchlorate has proven complex owing to the diverse characteristics of the perchlorate ion. Technologies such as chemical reduction, ozone/peroxide, nanofiltration, and reverse osmosis have had limited success, high costs and are not environmentally friendly. A great deal of research and reviews on ion exchange and biodegradation have been carried out, but conditions for ...

  • Vermifilters: a tool for aerobic biological treatment of herbal pharmaceutical wastewater

    Herbal pharmaceutical wastewater possesses high chemical oxygen demand (COD) (21,960–26,000 mg/l) and biochemical oxygen demand (BOD) (11,200–15,660 mg/l) and suspended solids (SS) (5,460–7,370 mg/l). It cannot be directly discharged into surface water bodies, due to its highly biodegradable nature. Herbal pharmaceutical wastewater has been treated by using vermifilter, which is an ecosystem ...

  • Wastewater Treatment: Out with Conventional, in with Sustainable Wastewater Treatment

    The question?Water is one of the world’s most vital resources. It is critical to the survival of every living creature on the planet. The average human can only go a few days without consuming water in some capacity. Health experts stress drinking fluids throughout the day to remain properly hydrated. However, in some parts of the world, water is hard to obtain. Either there are no sources ...

  • Polyhydroxyalkanoate (PHA) production from sludge and municipal wastewater treatment

    Polyhydroxyalkanoates (PHAs) are biodegradable polyesters with comparable properties to some petroleum-based polyolefins. PHA production can be achieved in open, mixed microbial cultures and thereby coupled to wastewater and solid residual treatment. In this context, waste organic matter is utilised as a carbon source in activated sludge biological treatment for biopolymer synthesis. Within the ...

  • Reclaimed municipal wastewater for forage production

    This study aims to evaluate the possibility of using reclaimed municipal wastewater for agricultural purpose. We assessed the validity of municipal wastewater treatment, analyzing its chemical characteristics before and after the biological stabilization by pond treatment (WSP). The reclaimed municipal treated wastewater (TWW) was used to irrigate Cenchrus ciliaris. Experiments were carried ...

  • Modern Wastewater Treatment Solutions in a State-of-the-Art Pharmaceutical Production Environment

    From traditional wastewater treatment to zero-discharge strategy Traditional end-of-pipe solutions for dealing with effluents coming out of the production plant have being gradually substituted for an increasingly decentralised approach to treat selected wastewater streams in the most effective and economically sound way. Moreover, additional goals like reducing overall effluent emissions ...

  • Treatment of high strength resin production wastewater case study

    Problem Full-scale Incineration of this wastewater had proved very expensive due to the fuel input required and the ongoing incinerator maintenance costs. The polymer manufacturer sought treatment alternatives to save money. Initial biotreatment pilot work indicated that biotreatment was not feasible using conventional activated sludge technology even when the concentrated wastewater was ...

  • How Shasun maximises the investment in it`s biological wastewater treatment plant

    At the Dudley Shasun facility we have a 7500 m3 biological treatment plant that can treat up to 36 tonnes of waste COD per day. Part of this capacity is utilised to treat up to 15 tankers per day of third party aqueous waste. The waste is very varied, covering everything from leachates at only 2000ppm COD to industrial waste at up to 500,000ppm COD. The Strathkelvin respirometer forms a central ...

  • Toluene in sewage and sludge in wastewater treatment plants

    Toluene is a compound that often occurs in municipal wastewater ranging from detectable levels up to 237 μg/L. Before the year 2000, the presence of the aromatic hydrocarbons was assigned only to external sources. The Enhanced Biological Nutrients Removal Processes (EBNRP) work according to many different schemes and technologies. For high-efficiency biological denitrification and ...

  • Microbiology: The Key to Wastewater treatment case study

    The biological treatment of wastewater relies mainly on a consortium of heterotrophic and autotrophic bacteria. The fecal bacteria that are constantly introduced into the collection system are not the optimal bacteria for degrading the contaminants present in wastewaters. The soil bacteria that are introduced through inflow and infiltration are more effective at degrading the wastes and can ...

  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...
