Trade effluent is defined as any liquid waste which is discharged into the public sewerage system from a business. Sewage and liquid waste produced in residential homes is not defined as trade effluent, only waste which comes from a commercial establishment.
In the UK most businesses take their water supplies from local water companies, who also deal with the final treatment of their wastewater and trade effluent. The water companies charge for both supplying the water and treating the wastewater. The tariffs and calculations used in creating business water bills can be very complex, with significant opportunity for error. This article looks at what happens when businesses are overcharged on their water bills and how they can reclaim these unfair charges.
This technical guide explains what biological wastewater treatment is, how it works, and how it’s used to improve the quality of industrial waste water streams prior to discharge. The guide looks at the main types of treatment including aerobic, anaerobic and anoxic; the importance of Biological Oxygen Demand or BOD, and the different types of waste water treatment technologies currently including various types of bioreactor.
This technical guide explains how anaerobic wastewater treatment works, and how it’s used to improve the quality of industrial waste water streams. The guide looks at where this type of process is used and how it can improve treatment efficiency. It then reviews the most common types of anaerobic digester including the use of lagoons, blanket reactors and filter reactors.
In this article the experts at Water Treatment Services explain how UK water companies calculate business water bills and sewerage charges. The article looks at the different approaches applied to domestic and non-domestic customers; along with small, medium and large water users. It considers the role of the UK’s water industry regulator Ofwat in keeping things fair, and concludes by reviewing the different types of charging tariffs used by water companies.
This technical guide explains the process known as aerobic wastewater treatment, and how it is used to improve the quality of industrial wastewater streams. The guide looks at what the process involves, and how it works. It also considers each of the most popular types of aerobic system used by businesses including activated sludge, fixed bed bioreactors, moving bed bioreactors, membrane bioreactors and biological trickling filters.
Taking steps to improve effluent treatment in the food industry can lead to significant process improvements; it can save businesses money, keep them the right side of the law and improve environmental performance. All good news, but where do you start?
With an expanding population, increasing costs and the introduction of increasingly stringent environmental regulations we ask what are the major challenges now facing operators of wastewater treatment plant installations? We look at four main areas, highlight the key issues and examine how advances in technology could help improve performance.
