Bibliography

Describes a method for the determination of drainability of flocculated sludges. Also applies to sludge and sludge suspensions from: a) storm water handling; b) urban wastewater collecting systems; c) urban wastewater treatment plants; d) treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271/EEC); e) water supply treatment plants.
