BS EN 903:1994 PDF

What is BS EN 903 -  Determination of anionic surfactants about? BS EN 903 helps in determining the anionic surfactants by measurement of the methylene blue index MBAS. BS EN 903 applies to drink water, surface water as well as wastewater, e.g. for the determination of the primary degradation of surfactants being under investigation in test systems containing natural or synthetic wastewater. BS EN 903   applies to both laboratory scaled and technical wastewater treatment plants. In the case of effluents originating from municipal wastewater treatment plants, the MBAS index comprises not only synthetic but to a considerable extent also natural anionic surface-active substances. The range of BS EN 903 applies to concentrations of 0,1 to 5,0 mg/l and the limit of detection is about 0,05 mg/l for solutions of standard surfactants in distilled water.
