    摘要： A process that utilizes ammonium oxidizing bacteria (AOB) and anaerobic ammonium oxidizing (ANAMMOX) bacteria to remove ammonium from a wastewater stream. Sludge separated from the wastewater in a mainstream is processed in a sidestream that includes an anaerobic digester, a dewatering system, and a biofilm reactor. The anaerobic digester produces digested sludge that is dewatered, producing reject water that includes a relatively high ammonium concentration and a relatively low organic carbon concentration and a relatively high temperature. The reject water is treated in a sidestream deammonification biofilm reactor that includes biofilm carriers seeded with AOB and ANAMMOX bacteria that are effective to remove ammonium from the reject water. AOB and ANAMMOX bacteria on the media carriers is utilized to contact the wastewater in the mainstream and to remove ammonium therefrom.

    摘要： The invention pertains to a method (200, 300, 400) of at least partly removing at least one micropollutant from wastewater (104) comprising carbogenous compounds and at least one micropollutant. The method comprising the steps of: (a) dividing the wastewater (104) into a main stream (105) and a side stream (106); (b) treating main stream (105) with bacteria to reduce the content of carbogenous compounds to provide depleted wastewater (107) comprising at least one micropollutant; (c) treating the depleted wastewater (107) with a second portion of microorganisms (162), having the ability of degrading the at least one micropollutant, to, at least partly, remove the at least one micropollutant thereby providing treated water (170), wherein the second portion of microorganisms (162) have been enriched by feeding the side stream (106) to it before using the second portion of microorganisms (162) in treating the depleted wastewater (107); and (d) feeding a first portion of microorganisms (161), having the ability of degrading the at least one micropollutant, with the side stream (106), to enrich them for subsequent use in treating the depleted wastewater (107) to at least partly remove the at least one micropollutant.

    摘要： A process for converting ammonium (NH4+) of a mainstream of a wastewater plant to dinitrogen gas (N2), including the consecutive steps of i.) removing biodegradable carbon compounds in the mainstream, ii.) converting ammonium (NH4+) in the mainstream to nitrite (NO2−) in an aerated biological process containing ammonium oxidizing bacteria (AOB) in a nitration vessel (133a-133d); and iii.) denitrifying the resulting stream from step ii.) to dinitrogen gas in an anammox vessel (200). Growth of nitrite oxidizing bacteria (NOB) in step ii.) is prevented by periodically subjecting the bacteria in said nitration vessel (133a-133d) to water suppressing growth of nitrite oxidizing bacteria (NOB).
