BackgroundLogical Waste offers a benchtop Volatile Fatty Acid analyser capable of performing an automated titration to establish VFA, alkalinity and the VFA/Alkalinity ration of an anaerobic sample.
A 20-ml sample is placed in a sample holder, a pH probe is positioned to a pre-set height into the liquid and the titration is started using a simple membrane keypad on the instrument. The stages of the titration and finally the VFA, alkalinity and ratio is displayed on a clear OLED display. The sample is titrated against a standard acid solution via a small peristaltic pump. The sample is stirred using a magnetic bar and a stirrer integrated into the instrument.
A significant advantage of the Logical Waste VFA analyser is the ease of use with almost no human intervention. The analysis is based on the standard Nordmann method which is used globally. If the client wishes, the analyser may be programmed to use different methods, for example the 3 point VFA titration method devised by Kapp.
Logical Waste VFA titrator
VFA trending is essential for modern AD plant operation and the simplest form of monitoring plant health and is often used as early detection method for process failures.
No more waiting for a 3-5 day external turnaround on your VFA and no more inaccurate readings from a manual titration system.
