Characterization of preparation for fat separators

Fats, oils and greases in waste water frequently cause serious environmental problems. A commercial preparation was tested for its ability to degrade oil grease wastewater. As substrates, two fats (lard beef fat) four (rape seed oil, sunflower palm olive oil) were chosen. The degradation of different substrates investigated by the determination lipid at pH 7, temperature 25 °C, aerobic condition agitation 160 rev/min 14 days Erlenmeyer flasks. Simultaneously, lipolytic activity spectrophotometrically determined 420 nm. All degraded rate basic units (fatty acids). Rape lard decomposed bacterial lipase from preparation.
