Parameter Lanjutan dalam Pengolahan Air Limbah Secara Biologis

Beberapa parameter penting yang sering digunakan dalam proses pengolahan air limbah, yaitu sebagai berikut.

BOD

BOD or BOD5    = Total 5-d biochemical oxygen demand

sBOD               = Soluble 5-d biochemical oxygen demand

UBOD or BODu  = Ultimate biochemical oxygen demand

COD

COD                = Total chemical oxygen demand

bCOD              = Biodegradable chemical oxygen demand

pCOD              = Particulate chemical oxygen demand

sCOD               = Soluble chemical oxygen demand

nbCOD             = Nonbiodegradable chemical oxygen demand

rbCOD             = Readily biodegradable chemical oxygen demand

rbsCOD            = Readily biodegradable soluble chemical oxygen demand

sbCOD             = Slowly biodegradable chemical oxygen demand

bpCOD            = Biodegradable particulate chemical oxygen demand

nbpCOD          = Nonbiodegradable particulate chemical oxygen demand

nbsCOD          = Nonbiodegradable soluble chemical oxygen demand

Nitrogen

TKN                = Total Kjeldahl nitrogen

bTKN              = Biodegradable total Kjeldahl nitrogen

sTKN               = Soluble (filtered) total Kjeldahl nitrogen

ON                 = Organic nitrogen

bON               = Biodegradable organic nitrogen

nbON             = Nonbiodegradable organic nitrogen

pON               = Particulate organic nitrogen

nbpON            = Nonbiodegradable particulate organic nitrogen

sON                = Soluble organic nitrogen

nbsON            = Nonbiodegradable soluble organic nitrogen

Suspended Solids

TSS                = Total suspended solids

VSS                = Volatile suspended solids

nbVSS            = Nonbiodegradable volatile suspended solids

iTSS               = Inert total suspended solids
