Characterization of preparation for fat separators
Nova Biotechnologica et Chimica, 2021 Fats, oils and greases in waste water frequently cause serious environmental problems. A commercial preparation was tested for its ability to degrade oil and grease in wastewater. As substrates, two fats (lard and beef fat) and four oils (rape seed oil, sunflower oil, palm oil and olive oil) were chosen.
