  2. Biosorption - Wikipedia

    en.wikipedia.org/wiki/Biosorption

    Though bioaccumulation and biosorption are used synonymously, they are very different in how they sequester contaminants: . Biosorption is a metabolically passive process, meaning it does not require energy, and the amount of contaminants a sorbent can remove is dependent on kinetic equilibrium and the composition of the sorbents cellular surface. [9]

  3. Chemical phosphorus removal - Wikipedia

    en.wikipedia.org/wiki/Chemical_phosphorus_removal

    Maintaining optimal pH is important for the removal of phosphorus from water. Phosphorus is most effectively removed at the neutral pH range, when the insoluble aluminum hydroxide is present. This hydroxide functions as a Lewis acid , [ 5 ] creating a flocculation environment similar to conventional wastewater treatment.

  4. Electrocoagulation - Wikipedia

    en.wikipedia.org/wiki/Electrocoagulation

    Electrocoagulation (EC) is a technique used for wastewater treatment, wash water treatment, industrially processed water, and medical treatment. Electrocoagulation has become a rapidly growing area of wastewater treatment due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, total petroleum ...

    en.wikipedia.org/wiki/Advanced_oxidation_process

    A goal of the wastewater purification by means of AOP procedures is the reduction of the chemical contaminants [7] and the toxicity to such an extent that the cleaned wastewater may be reintroduced [8] into receiving streams or, at least, into a conventional sewage treatment.

  9. Rotating biological contactor - Wikipedia

    en.wikipedia.org/wiki/Rotating_biological_contactor

    The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
