ANALYS AV VFA – EN ENKEL TITRERMETOD / Analysis of VFA – A Simple Titration Procedure
A decisive factor in the operation of an enhanced biological phosphorus removal (EBPR) process is th availability of readily biodegradable organics in the influent. Especially important is the amount of volatile fatty acids, VFA.
At the WWTP in Helsingborg, Öresundsverket, full-scale EBPR-tests in two of the four trains are running. Hydrolysis of primary sludge in the primary clarifiers generates VFA. A simple titradon procedure, named five-point-titrarion, was tested to analyze total VFA-content of the preclarified effluent. The presented procedure ofVFA-analysis is recommended to laboratories at WWTPs. Standard laboratory equipment and a PC are required.
