  • What is a wastewater treatment system and how does it work?

    For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s process or products (especially if the wastewater ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Peach Processing Wastewater Treatment

    A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...
