KORSØR RENSEANLÆG er et MBNDK renseanlæg. Det vil sige at anlægget hører til blandt de mest avancerede danske renseanlæg.
Spildevandet renses først mekanisk (M) ved at løbe igennem riste, således at faste genstande frasorteres. Det såkaldte ristegods, som eksempelvis klude, bind, vatpinde m.m. opsamles i en container og køres til forbrænding.
Dernæst renses biologisk (B) i luftningstanke. Biologisk rensning foregår ved at føre vandet igennem et eller flere biologiske filtre (tykke lag stenskærver med enorme mængder levende bakterier og andre mikroorganismer, der via respirationsprocessen nedbryder vandets indhold af organiske stoffer).
Nitrificering (N) er iltning af Ammonium til Nitrat (NO3). Denitrifikation (D) udføres af bakterier således at Nitrat bliver omsat til frit kvælstof (N2), som afgives til atmosfæren.
Endelig udføres der kemisk (K) rensning ved at tilsætte spildevandet et eller flere kemiske stoffer, f.eks. jern eller aluminiumforbindelser. Derved startes en fældningsreaktion, som danner et tungopløseligt stof, der binder sig til det resterende slam, som bundfældes og kan frafiltreres.

KORSØR WASTE PLANT is an MBNDK wastewater treatment plant. This means that the plant is one of the most advanced Danish treatment plants.
The wastewater is first mechanically cleaned (M) by running through the grate so that solid objects are separated. The so-called rice goods, such as cloths, napkins, cotton swabs etc. is collected in a container and run for incineration.
Next, biological (B) is purified in aeration tanks. Biological cleansing is carried out by passing the water through one or more biological filters (thick layers of stone fragments with huge amounts of living bacteria and other microorganisms that break down the water's organic matter content through the respiration process).
Nitrification (N) is the oxidation of Ammonium to Nitrate (NO3). Denitrification (D) is carried out by bacteria so that Nitrate is converted to free nitrogen (N2) which is released into the atmosphere.
Finally, chemical (K) purification is performed by adding the wastewater to one or more chemical substances, e.g. iron or aluminum compounds. Thereby, a precipitation reaction is started which forms a heavily soluble substance which binds to the remaining sludge which is precipitated and can be filtered off.
