  • Sewage Treatment - Klargester is the market leader for small and medium-sized domestic treatment plant and waste water treatment systems in the UK

    Sewage treatment plant operate by providing an environment in which aerobic bacteria are cultured. These bacteria survive by using biological matter in the sewage as a food source. To provide optimum treatment the bacteria need free access to oxygen and immersion in the sewage effluent. The majority of package plant work by providing a fixed medium that the bacteria adhere to, and a means of ...

  • 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 ...

  • What is biological wastewater treatment?

    Biological wastewater treatment harnesses the action of bacteria and other microorganisms to clean water Biological wastewater treatment is a process that seems simple on the surface since it uses natural processes to help with the decomposition of organic substances, but in fact, it’s a complex, not completely understood process at the intersection of biology and ...

  • An Infrastructure Grows · Decentralized Treatment and Recycling Domestic Wastewater

    THE TERM, “decentralized waste-water management,” refers to the process of treating and discharging treated wastewater in the local vicinity where it is generated. Decentralized systems typically use the soil as the final receptor of the treated wastewater instead of discharging to surface waters, which are generally the receptors of treated wastewater from larger centralized treatment plants. ...


  • Dogs put trust in onsite sewage treatment

    One of the obvious challenges of running Dogs Trust rehoming centres is the need to dispose of a significant quantity of hazardous waste. All locations not connected to mains drainage have to be served by reliable on site treatment systems and on completion of the latest installation at Salisbury a total of five WPL systems will be in operation around the UK. The charity cares for some 16,000 ...

  • Treatment of domestic wastewater using composite ecological system in Chinese rural area

    In this study, a newly developed contaminant removal system for domestic wastewater in rural area was used at the first time in Henan province, China. This composite ecological system (CES) consists of septic tank (ST), improved soil filter (ISF) and surface flow wetland (SFW). The performances of the system was to investigate the removal of biological oxygen demand (BOD), total nitrogen (TN), ...

  • Anaerobic Processes as the Core Technology for Sustainable Domestic Wastewater Treatment: Consolidated Applications, New Trends, Perspectives, and Challenges

    Anaerobic digesters have been responsible for the removal of large fraction of organic matter (mineralization of waste sludge) in conventional aerobic sewage treatment plants since the early years of domestic sewage treatment (DST).  Attention on the anaerobic technology for improving the sustainability of sewage treatment has been paid mainly after the energy crisis in the 1970s. The successful ...

  • WPL’s easy to install diamond sewage treatment plant case study

    If you are lucky enough to be involved with a building project in the beautiful countryside of Great Britain, one thing you will find most properties have in common here is that they are likely to be off-mains drainage. When involved with an off-mains building project, it is important that you do know where your wastewater goes and what happens to it, usually by means of a domestic sewage ...

  • Treatment of Biogas Produced in Anaerobic Reactors for Domestic Wastewater: Odor Control and Energy/Resource Recovery

    Anaerobic municipal wastewater treatment in developing countries has important potential applications considering their huge lack of sanitation infrastructure and their advantageous climatic conditions. At present, among the obstacles that this technology encounters, odor control and biogas utilization or disposal should be properly addressed. In fact, in most of small and medium size anaerobic ...

  • Sludge Treatment and Disposal Technologies

    Most wastewater treatment processes produce a by-product that purifies wastewater before it is released into local waterways. This by-product is named as sludge. Typically in solid, semi-solid or liquid state, it is in fact an amalgamation of all the liquid wastes that are discharged by domestic houses, commercial properties, industry, and/or agriculture after aerobic biological treatment. ...

  • Removal of Microorganisms from Domestic Greywater Using a Recycling Vertical Flow Constructed Wetland (RVFCW)

    ABSTRACTThe reuse of greywater (GW) is an attractive addition to water management options. One of the major concerns limiting GW reuse is the possible presence of harmful microorganisms. In addition to total coliform organisms, enteric organisms (Salmonella, Shigella and poliovirus Type 1 Cryptosporidium, Giardia) and opportunistic pathogens ( Staphylococcus aureus and Pseudomonas aeruginosa) may ...

  • Microbe Edition: Biological Nutrient Removal How In-Pipe Technology Works

    Biological Nutrient Removal (BNR) is critical for tie preservation of our lakes and streams. Large amounts of waste products are passed through our sewage treatment systems on a continuous basis. Nutrient loads discharged from these systems must be reduced to avoid eutrophication of the receiving waters. Microbes are aarticularly useful in biodegrading most of the com sounds treated by wastewater ...

  • Long Term Full Scale Comparison of Activated Sludge (AS) With Biological Aerated Filter (BAF)

    The Wastewater Treatment Plant (WWTP) of Frederikshavn, Denmark, was extended in the early nineties to increase its average daily flow to 4,5 MGD (16,500 m³/d) and meet new requirements for nutrient removal (8 mg/l TN, 1,5 mg TP/l). A parallel biological aerated filter (BAF) was the selected as the most economical upgrade of the existing activated sludge plant (AS), and started up in 1995. ...

  • 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 ...

  • Wastewater Treatment in Turbo Mode

    Sulzer turbocompressors type ABS HST are successful in wastewater treatment. Today, 2000 units are installed around the world—for example, in municipal plants like in the city of Sögel, Germany. Here, the turbocompressors not only reduced the operating costs but also helped the plant to cope with load fluctuations. The secret behind this success is an advanced design with proven ...

  • Septic Tanks - Klargester provide a reliable, economic and efficient solution to your sewage disposal needs

    A septic tank is a retention vessel designed to receive sewage, hold it for a period and then release a clarified effluent. Sewage is a mixture of toilet wastes, kitchen wastes and so called grey wastes i.e. liquids which include washing, bath and washing machine wastes. A septic tank is primarily a liquid/solid separation system, although there may be some limited biological activity within the ...

  • Assessment of treatment capabilities of Varthur Lake, Bangalore, India

    Manmade waterbodies have traditionally been used for domestic and irrigation purposes. Unplanned urbanisation and ad-hoc approaches have led to these waterbodies receiving untreated sewage. This enriches and eutrophies the waterbody. A physico-chemical and biological analysis of sewage-fed Varthur Lake in Bangalore was carried out and its treatment capabilities in terms of BOD removal, nutrient ...
