The degree of water pollution caused by oils from cleaners and degreasers

U nizu tehnoloških procesa kao i za održavanje postrojenja korisie se sredstva za odmašćivanje i čićenje. Najveći deo tih sredstava nakon upotrebe završava u vodama pa moraju biti zadovoljeni uslovi propisani zakonima o vodama. Uticaj tih proizvoda na vode ocenjuje se između ostalog i preko njihovog svojstva demulgiranja. U radu su prikazani rezultati ispitivanja koncentracije ugljikovodonika u vodi nakon odmašćivanja i čišćenja. Ispitivanja su sprovedena na 100 proizvoda koja se nalaze na tržistu.Various degreasers and cleaners are used in technological processing and for plant maintenance. Most of them fend their way into water through the drains and they must comply with the waste water regulations. Their ability to deemulsify is important factor in estimation of their influence on the water. This paper presents the results of hydrocarbons concentration measured after cleaning and degreasing. Measuring is performed on 100 products in use on the market
