2. Chemical phosphorus removal - Wikipedia

   en.wikipedia.org/wiki/Chemical_phosphorus_removal

   One method of eutrophication remediation is the application of aluminum sulfate, a salt commonly used in the coagulation process of drinking water treatment. Aluminum sulfate, or "alum" as it is commonly referred, has been found to be an effective lake management tool by reducing the phosphorus load.

   Sulfate reduction coupled to ammonium oxidation, or sulfammox, is a novel multi-step microbial process especially pertinent to industrial wastewater treatment. Microbial species associated with sulfammox include but are not limited to Anammoxoglobus sulfate, Bacillus benzoevorans, Candidatus_ Anammoxoglobus, Bacillus cereus SUD-1.

6. Flue-gas desulfurization - Wikipedia

   en.wikipedia.org/wiki/Flue-gas_desulfurization

   The chief drawback of spray towers is that they require a higher liquid-to-gas ratio requirement for equivalent SO 2 removal than other absorber designs. FGD scrubbers produce a scaling wastewater that requires treatment to meet U.S. federal discharge regulations. [14]

7. In situ chemical oxidation - Wikipedia

   en.wikipedia.org/wiki/In_situ_chemical_oxidation

   Various agents, such as heat, ultraviolet light, high pH, hydrogen peroxide, and transition metals, are used to activate persulfate ions and generate sulfate radicals. [8] The sulfate radical is an electrophile, a compound that is attracted to electrons and that reacts by accepting an electron pair in order to bond to a nucleophile. Therefore ...
