To maintain the balance between these two processes control of the pH is utilized. [3] In this process works as a chemostat making the SLT(Sludge Retention Time) the same as the HLT(Hydraulic Retention Time). This characteristic makes the process insensitive to suspended solids concentrations in the water. [4]
The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa. It is one of several biological wastewater treatment alternatives in secondary treatment , which deals with the removal of biodegradable organic ...
Treatment of wastewater to improve sanitation is a major challenge in developing countries, as untreated wastewater can contaminate drinking water. Anammox bacteria treatments have been implemented in treatment facilities to help convert sewage wastewater into sludge ash , which is then used as a fertilizer source for agriculture. [ 8 ]
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [1] for subsequent use. [2] More recently, technology has been developed that allows the treatment and reduction of other [3] organic waste, such as food, cardboard and horticultural waste. It is a bacterial process occurring ...
Adsorption/bio-oxidation process is a part of innovative wastewater treatment concept WaterSchoon, realized in the Netherlands. 250 apartments in the new district Noorderhoek (Sneek, the Netherlands) are equipped with separate collection systems for toilet wastewater and the rest of the household wastewater (or so-called greywater). Both ...
[3] Generally speaking, all bacteria contain a fraction (1-2%) of phosphorus in their biomass due to its presence in cellular components, such as membrane phospholipids and DNA . Therefore, as bacteria in a wastewater treatment plant consume nutrients in the wastewater, they grow and phosphorus is incorporated into the bacterial biomass.
O 3 + HO 2 − → HO 2 · + O 3 − · (a second O 3 molecule reacts with the HO 2 − to produce the ozonide radical) O 3 − · + H + → HO 3 · (this radical gives to ·OH upon protonation) HO 3 · → ·OH + O 2 the reaction steps presented here are just a part of the reaction sequence, see reference for more details.
