Physicochemical characteristics of struvite crystals formed in palm oil mill effluent anaerobic digester

The formation of struvite crystals in palm oil mill effluent (POME) occurs as early as in the secondary stage of POME treatment system. It continues to occur in the following tertiary treatment reducing the piping diameter thus affecting the efficiency of the treatment process. It is rarely being re...
