摘要: Abstract Huge amount of slurry produced in high-density livestock farming needs proper management and utilization methods. The integrated system centrifugation/two-step ultrafiltration/nanofiltration was used to recover water from pig slurry. PVDF UF (100 50 kDa), PES (10 5 kDa) composite hydrophilic NF membranes (0.2 kDa) were used. System efficiency validated according final product quality capacity. influence membrane fouling on their performance properties also investigated. study showed that among all discussed configurations centrifugation–UF50–UF5–NF0.2 the most effective. Thirty-three percentage initial crude volume obtained as permeate. Strong capacity observed for UF, while it had an impact properties. finally suitable be reused a sanitary safe industrial e.g. washing animals farmhouses.
