Explain the Typical Wastewater Characteristics?
Total Suspended Solids = 100 - 350 mg/L (200 mg/l is the typical value)
BOD5 = 100-300 mg/L (200 mg/L is the typical value)
33% of the total solids (ST) are suspended (60% of these suspended solids are settle able and 40% are colloidal) and 67% are dissolved.
Total Solids (ST) = Fixed or Inorganic Solids (SF or SI) + Organic or Volatile Solids (SV or SO)
The solids removed during primary and secondary treatment are referred to as sludge (high solids concentration).
