  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • 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 ...

  • Sustainable wastewater treatment chemicals in a food processing plant

    A food ingredients manufacturer was using an inorganic aluminium metal salt with pH correction to treat their effluent. This chemical regime refused to give them any real control over their effluent characterisation. Their effluent plant required constant monitoring and adjustment. The inability to control the characterisation of the effluent exiting the site meant non-compliance to the ...

  • Chemical wastewater treatment applying a membrane bioreactor (MBR)

    IntroductionAt the current time Membrane Bioreactors (MBR) are the primary focus of wastewater treatment technologies. MBR is a combination of biological activated sludge process for the removal of nutrients and a membrane filtration for separation of biomass and treated water. In industrial wastewater treatment MBRs have proven to be a particularly reliable technique [Cornel et al., 2006]. The ...

  • Sustainable wastewater treatment chemicals in a chicken processing plant

    Atana Ltd was invited to evaluate the potential for introducing an organic, sustainable wastewater treatment regime into a chicken processing plant. The flow was approximately 120m³ (over 18 hours per day). The plant killed around 126000 birds per day and the sludge volume produced from their effluent treatment plant (which encompassed dissolved air flotation) per annum was around 13000 ...

  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...

  • Wastewater Treatment Process

    The wastewater treatment process is complex and critical to civilization. In simplest terms, wastewater is water that has been mixed with waste matter. Wastewater can be classified as domestic, municipal, or industrial based upon the source of generation. For instance, domestic wastewater comes from everyday liquid waste, including water used to flush the toilet, to shower, or to wash dishes. ...

  • An outline of textile wastewater treatment

    The issues of wastewater are not restricted to any particular industry. Almost every sect including textile, manufacturing, and food processing industry are going through the harsh situation of wastewater, and with the implementation of versatile technologies, different organisations are trying their best to eradicate the soaring volume of wastewater.  The textile industry is ...

  • On-site industrial wastewater treatment

    Priority pollutant behaviour in on-site treatment systems for industrial wastewaters The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ...

  • Wastewater Treatment & Recycle

    Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

  • 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 ...

  • How chemical treatment programmes can help to boost the efficiency of wastewater treatment

    Ipek Ozturk, Product Manager Wastewater of Kurita Europe, explains how chemical treatment programmes can help to boost the efficiency of wastewater treatment. Successful wastewater treatment is crucial for the smooth operation of refineries and petrochemical plants. A clever chemical treatment programme is able to increase the ratio of water recycling, yielding in ...

  • 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 ...

  • 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. ...

  • Mirror Plating Wastewater Treatment

    In the manufacturing of certain mirrors, a strong copper solution at low ph is used to apply a thin coating to the glass surface. After adhesion, the excess is washed off and collected as wastewater. The wastewater at this facility is treated using 4 chemicals: caustic to raise the pH to 8.5, DTC (dithiocarbamate) as a metal precipitant, an organic based coagulant, and an anionic flocculant. The ...

  • Physico-chemical treatment for the depuration of wine distillery wastewaters (vinasses)

    ABSTRACTIn the present work, an integrated Fenton-coagulation/flocculation process was applied for the depuration of wine distillery wastewaters, commonly known as 'vinasses'. This study evaluates the Fenton process (H2O2/Fe2+), involving oxidation – in a first stage and coagulation/flocculation (using Ca(OH)2 as base-precipitant) – in a second stage ...
