Application of advanced oxidation process combining anaerobic granular sludge on refractory industrial wastewater treatment

1755-1315/474/5/052095

An AOPs of Fe/C micro-electrolysis (FCME) and Fenton oxidation (FO) was combined with anaerobic granular sludge (AGS) to treat recalcitrant pharmaceutical wastewater in this study. The AOPs showed significant COD reduction during both FCME and FO. For influent COD=9000∼11000mg/L, the pretreatment effluent COD could reach below 5500mg/L under 0.6% H2O2 adding condition. And the B/C of pharmaceutical wastewater was improved from 0.11 to 0.37. The subsequent AGS treatment in EGSB got a COD removal rate of 87.1%. The extracellular polymeric substance (EPS) and mean diameter detection demonstrated high stability of EGSB. AOPs with AGS is supposed to be a better option for recalcitrant wastewater treatment process.

Aerobic granular sludge & enhanced settling biological treatment market update

Innovation Type:

Radical Functionality: The technology allows (enables) to do something that was not previously possible. For example, Struvite precipitation for phosphorus recovery.

Discontinuous: This technology utilises new materials or processes in the creation of existing technologies or to fulfil existing functions. It does the same thing in a different way. It disrupts the existing value chain. For example, UV LED Disinfection.

Sustaining: The technology improves an existing process through continual innovation. For example, makes it more efficient. For example, MBBR.

Do sewage treatment plants use chemicals?

  Wastewater originates from households, businesses, industry as well as storm drains and rainwater runoff. In general, wastewater contains approximately 99.9% water, with the remaining 0.1% representing dissolved solids or other suspended material. This material may include excreta, detergents from washing clothes and dishes, food residues, grease, oil, plastics, salt, sand, grit and heavy metals. Some wastewater from industrial or agricultural processes may also contain chemicals that may be harmful to the environment or public health and need to be neutralised or removed from the water before they can be safely reintroduced into the environment. The main objective of the wastewater treatment process is to purify the water and ensure that it is safe for subsequent use once it has been returned to the environment as part of the water cycle. Wastewater treatment involves several stages involving mechanical (physical), biological, chemical and membrane (filtration) based processes. ...
