What is BS EN 872 - Determination of suspended solids about?
BS EN 872 describes a method for the determination of suspended solids in raw waters, waste waters and effluents by filtration through glass fibre filters. The lower limit of the determination is about 2 mg/l. No upper limit has been established.
Water samples are not always stable which means that the content of suspended solids depends on storage time, means of transportation, pH value and other circumstances. Results obtained with unstable samples need to be interpreted with caution.
Floating oil and other immiscible organic liquids will interfere (see Annex A). Samples containing more than about 1 000 mg/l of dissolved solids can require special treatment (8.6).
Note 1 : The result of the determination depends to some extent on the type of filter used (5.2). It is therefore recommended that the type of filter is specified.
Note 2 : The size distribution of particles in different samples can vary widely. Therefore there is no correlation between results obtained with filters of different pore width and no conversion factor can be given for the conversion of results obtained with one type of filter to another.
Who is BS EN 872 - Determination of suspended solids for?
BS EN 872 on the Determination of suspended solids is useful for:
- Wastewater collecting systems
- Wastewater treatment plants
- Plants treating industrial wastewater
- Water supply treatment plants
Why should you use BS EN 872 - Determination of suspended solids?
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 872 describes methods and procedures for determining suspended solids present in raw water using the method of filtration through glass fibre filter.
BS EN 872 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 872 assist you in the determination of suspended solid particles in water and ensure reducing the risk of severe health issues.
With obedience and compliance to BS EN 872, you can enhance the efficacy of the water and manufacture a standardized product.
