Sewage treatment plant

BONO ARTES has developed an activated sludge process called BIOCLAR, which is a great technological step forwards compared to conventional methods. A large part of civil and industrial installations, especially in developing countries, is located in remote and secluded areas where there is no possibility for connection to a public sewer. On the other hand, the minimisation of the impact on the ...

Ozonation of estrogenic chemicals in biologically treated sewage

The present study shows that ozonation of effluents from municipal wastewater treatment plants (WWTPs) is likely to be a future treatment solution to remove estrogens and xeno-estrogens. The required ozone dose and electrical energy for producing the ozone were determined in two WWTP effluents for removal of 17 estrogenic chemicals. The estrogenic compounds included parabens, industrial phenols, ...

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 ...

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 ...

Behavior and fate of anthropogenic substances at a Swedish sewage treatment plant

The behavior and fate of anthropogenic substances during sewage treatment were investigated at a sewage treatment plant (STP) in Sweden which uses mechanical, chemical, and biological methods for sewage treatment and anaerobic digestion of sludge. Influent and effluent water, and sludge from two specific treatment sites were sampled. Mass balances were calculated from measured concentrations of ...

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 ...

Wastewater treatment plant implements MBR – technology for sewage water from hospital

The chemical industry is facing a multitude of economical and environmental challenges. Not only is it detrimental for a chemical plant’s continuous existence in today’s global environment to become more and more cost-effective, the environmental regulations are also becoming increasingly stringent. Hence, the MBR technology with its high quality effluent proves to be a good fit for ...

Analysis and occurrence of typical endocrine-disrupting chemicals in three sewage treatment plants

Seven typical endocrine-disrupting chemicals (EDCs), including bisphenol A (BPA), 4-tert-octylphenol (OP), estrone (E1), estradiol (E2), 17α-estradiol (17α-E2), estriol (E3) and 17α-ethinylestradiol (EE2) in wastewater, were simultaneously determined with gas chromatography–mass spectrometry (GC–MS). Samples, including influents, effluents and wastewater of different unit processes, were taken ...

High Rate Biological Odour Control Demonstration for Biosolids Exhausts

Abstract Biorem has successfully demonstrated its high rate odour control system for biosolids exhausts at Ashbridges Bay sewage treatment plant in Toronto, Ontario. The demonstration used XLD™, a biofiltration media engineered specifically for biosolids odours. The system has achieved 95% odour removal in less than 20-s Empty Bed Residence Time (EBRT) despite high concentration of ...

Acetic acid recovery from a hybrid biological–hydrothermal treatment process of sewage sludge – a pilot plant study

A two-stage process consisting of anaerobic fermentation followed by sub-critical wet oxidation was used to generate acetic acid from sewage sludge at pilot scale. Volatile fatty acids, dominated by propionic acid, were produced over 4–6 days in the 2,000 L fermentation reactor, which also achieved 31% solids reduction. Approximately 96% of the carbon was retained in ...

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 ...

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 ...

Occurrence and elimination of antibiotics in three sewage treatment plants with different treatment technologies in Urumqi and Shihezi, Xinjiang

Fourteen antibiotics, including five quinolones (QNs), five sulfonamides (SAs), and four tetracyclines (TCs), were selected to investigate their occurrence and elimination in three sewage treatment plants (STPs) by employing different treatment technologies in Urumqi (two STPs) and Shihezi (one STP), China. The STP in Shihezi was chosen as representative to investigate the distribution of ...

Using a continuous-fill, intermittent-discharge SBR to remove biological nutrients

Five years ago, the Town of Essex, in southwestern Ontario, decided to upgrade its facultative lagoon treatment systems with an alternative wastewater treatment plant — a continuous-fill, intermittent-discharge sequencing batch reactor (CFID-SBR) system, targeting even higher effluent quality. The CFID SBR process was designed by Premier Tech Aqua, which also provided major process ...
