Effectiveness Magnesium ammonium phospate (MAP) precipitation and filtration method in treatment of palm oil mill effluent (POME)

Effectiveness Magnesium ammonium phospate (MAP) precipitation and filtration method in treatment of palm oil mill effluent (POME)

The process of oil extraction from palm oil industry resulted in the generation of liquid waste commonly known as palm oil mill effluent (POME). P0MB is a viscous brown liquid containinghigh concentrations of fine suspended solids, oil and grease andother contaminants. Several treatment technologies...
