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.
Who is BS EN 903 - Determination of anionic surfactants for?
BS EN 903 on the Determination of anionic surfactants is useful for:
- Wastewater collecting systems
- Wastewater treatment plants
- Plants treating industrial wastewater
- Water supply treatment plants
Why should you use BS EN 903 - Determination of anionic surfactants?
A color reaction in an acidified, aqueous methylene blue solution containing chloroform can detect anionic surfactants in a water sample such a test is known as the MBAS test.
Filtration is the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles.
BS EN 903 describes methods and procedures for determining anionic surfactants present in raw water by measuring the methylene blue index MBAS.
BS EN 903 provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, test procedure, and much more.
The test methods and procedures provided by BS EN 903 assist you in the determination of anionic content in water and ensure reducing the risk of severe health issues.
With obedience and compliance to BS EN 903, you can enhance the efficacy of the water and manufacture a standardized product.
