What is BS EN 14742 - Characterization of sludges about?
BS EN 14742 is an international standard used for the characterization of sludges that specifies the test method and test procedures for sludges. BS EN 14742 is useful in selecting the conditioning product and helps in producing good quality sludges.
BS EN 14742 specifies laboratory assessment of sludge dewaterability is sensitive to the operating procedure adopted for the conditioning step. No generalized ranking of products in order of effectiveness can be given since the ranking changes with the sludge type, dosage of conditioning agent, degree of shearing and dewatering device.
Note: The scope of BS EN 14742 applies for sludges and suspensions from:
- Stormwater handling
- Urban wastewater collecting systems
- Urban wastewater treatment plants
- Industrial wastewater that has been treated similarly to urban wastewater (as defined in Directive 91/271/EEC)
- Water supply plants.
Note 2: This method is applicable to sludge and suspensions of another origin.
Who is BS EN 14742 - Characterization of sludges for?
BS EN 14742 on Characterization of sludges is useful for:
- Agricultural farming
- Manufacturer of sludge
- Water waste management
- Agricultural research
- Research laboratories
Why should you use BS EN 14742 - Characterization of sludges?
Sludge is a semi-solid slurry residual material that is useful in producing as a by-product of wastewater treatment processes.
BS EN 14742 specifies the test method and test procedure for the characterization of sludges. This test method helps in determining the required nature of the reagent, the dosage, and the sequence of adding the reagent. With the help of BS EN 14742, you can identify the chemical and physical parameters of these sludges. The mixing method is useful in adding appropriate conditioning products to the sludges. By using BS EN 14742 you can choose appropriate conditioning product that results in manufacture good quality sludges for the dewatering test.
