Activated Sludge | SSWM
Activated sludge reactors are aerobic suspended-growth type processes (in opposition to fixed-film or attached-growth processes (e.g. RBCs).Different configurations of the activated sludge process can be employed to ensure that the wastewater is mixed and aerated in an aeration tank. Aeration and mixing can be provided by pumping air or oxygen into the tank or by using surface aerators.
wastewater treatment process. What happens in the wastewater plant is the same as happens in nature but safer and faster. Nowadays the sewage collection systems and wastewater treatment is almost perfect and quality of discharged water to the nature and public hygiene are way better than before. 2 OVERALL GOALS OF WASTEWATER TREATMENT:

The 55 chapters are divided into 7 parts over two volumes: Volume One: (1) Introduction to wastewater characteristics, treatment and disposal; (2) Basic principles of wastewater treatment; (3) Stabilisation ponds; (4) Anaerobic reactors; Volume Two (also available in the SSWM library): (5) Activated sludge; (6) Aerobic biofilm reactors; (7
Singapore’s Waste Management • In 2003, 6877 tonnes/day (2.51 M tonnes/year) of MSW collected for disposal (0.94 kg/c/d) • 57.3% (household) Vs 42.7% (industry) • 92% was disposed of at the 4 incineration plants • 8% (non-incinerable waste) and incineration ash goes to the offshore Semakau Landfill

Wastewater treatment management systems. Source: prepared by the author based on information from openstreetmap (2025) . However, if the WWTP performance is poor, or if wastewater treatment is limited to organic matter removal, like in Curauma, the waters receiving wastewater are affected by organic material and nutrients, thus polluting water
The United Nations World Water Development Report 2017
The 2017 edition of the United Nations World Water Development Report (WWDR) explores the issue of wastewater and its potential as a sustainable resource. However, the findings show how much work we have to do: “Worldwide, the vast majority of wastewater is neither collected nor treated.
The consequences are devastating: poor sanitation and contaminated drinking water resources cause more than 80 per cent of all disease in the developing world (WHO, 2003, CDC, 2011).An estimated 1.8 billion people consume faecal-contaminated water, and this increases the health risk of water-borne diseases – such as diarrhoea – which kill 700,000 infants per year (UNICEF-IGME, 2012).
Anaerobic digestion and integration at urban scale
The anaerobic digestion process is well studied and developed since the last 50 years, notably for farming implementation. Furthermore, the international energy agenda has shifted in favor of renewable resources. In this context, anaerobic digestion has been highlighted as a valuable source of green energy. At urban scale, since the 2000s, some eco-friendly districts and cities tried to
SSWM employs systems to track and document hazardous wastes to ensure that significant quantities are not mixed with other wastes but are taken to secured facilities for hazardous wastes treatment and disposal. SSWM recognizes the need for reliable data to ensure effective planning and management
- What is the global polyacrylamide market size?
