- Abstract
Biogas slurry as an inevitable outcome of biogas project contains a lot of nutrients such as nitrogen and phosphorus. In order to solve the difficulties in storage of biogas slurry and recycle the nutrients, phosphorus from simulated biogas slurry was concentrated by reverse osmosis membrane. Economic evaluation of the system is also analyzed in the paper. Results showed that the reverse osmosis membrane has good concentration effects on phosphorus from biogas slurry. Finally, phosphorus content in concentrated effluent increased 7.8 times, 8 times, 10.4 times from simulated biogas slurry of different initial concentrations (60 mg/L, 90 mg/L, 120 mg/L), respectively. The optimal washing time of the system is 1 min.
