Ngalaba ikpofu ihe mkpofu kichin na-abawanye ibu nke carbon organic na-erute ebe a na-edozi mmiri, nke na-eme ka oriri oxygen na-abawanye.Metcalf na Eddy tụlere mmetụta a dị ka 0.04 pound (18 g) nke ikuku oxygen na-achọ onye ọ bụla kwa ụbọchị ebe a na-eji ihe mkpofu. Ihe mkpofu in-sink rụrụ nke ọma n'ihe gbasara mgbanwe ihu igwe, acidification, na ojiji ike, o nyere aka na eutrophication na ike nsi.
Nke a nwere ike ibute ọnụ ahịa dị elu maka ike dị mkpa iji nye oxygen na arụ ọrụ nke abụọ.Otú ọ dị, ọ bụrụ na a na-achịkwa ọgwụgwọ mmiri mkpofu nke ọma, carbon organic dị na nri nwere ike inye aka mee ka mmebi nke nje na-agba ọsọ, n'ihi na carbon nwere ike ghara ịdị na usoro ahụ.Carbon a na-abawanye na-eje ozi dị ka isi iyi carbon dị ọnụ ala yana na-aga n'ihu dị mkpa maka iwepụ ihe ndị na-edozi ahụ.
Otu nsonaazụ bụ nnukwu ihe fọdụrụ siri ike sitere na usoro ọgwụgwọ mmiri mkpofu.Dika nnyocha emere n'ebe a na-ekpocha mmiri mkpofu nke East Bay Municipal Utility District nke EPA kwadoro, ihe mkpofu nri na-arụpụta okpukpu ato nke biogas ma e jiri ya tụnyere sludge nke ime obodo.Uru nke biogas sitere na mgbari anaerobic nke ihe mkpofu nri na-egosi na ọ gafere ọnụ ahịa nke nhazi mkpofu nri na ikpofu biosolids fọdụrụnụ (dabere na atụmatụ ọdụ ụgbọ elu LAX iji tụgharịa 8,000 ton / afọ nke nnukwu ihe mkpofu nri).
N'ime nnyocha e mere na ụlọ ọrụ ọgwụgwọ mmiri Hyperion dị na Los Angeles, iji ihe mkpofu egosighi mmetụta ọ bụla na mkpokọta biosolids site na ọgwụgwọ nsị na mmetụta yiri nke ahụ dị ntakịrị na nhazi usoro dị ka nnukwu mbibi siri ike na-agbanwe agbanwe (VSD) site na mkpofu nri na-amịpụta ntakịrị. ego nke siri ike na fọdụrụ.
