Respirometer

Determination of the dynamic respiration index

Description

The respirometer is an instrument that allows to measure the «Dynamic Respirometric Index» (DRI).

The measurement of the respiratory activity of the organic matrix is the most significant parameter for determining biological stability.

The DRI is the result of the dynamic respirometrictest that measures the hourly oxygen consumption used for the biochemical oxidation of biodegradable compounds.

  • Determination of the biological stability of a biomass performed by measuring the respiration index using the dynamic method DiFCA (1) (now Di.Pro.Ve.).
  • Performance of biostabilization and/or biodrying tests comparable with full-scale processes conducted in the plant.
  • Monitoring of the main process parameters, evaluation of their trends and the possibilities of acting on them during respiration tests.
  • Recording a large quantity of data using a PC equipped with an interfacing board and software that allows minimum acquisition intervals of 1 minute.

Compared to the previous model, the Respirometer 3028 has been implemented and updated to modern technologies. The main points of innovation and advantage of the new equipment are listed below:

  • The control panel includes all the latest innovations available on the market; it is much more durable and easy to update.
  • The control panel has a large internal memory for storing multiple analyses, always retrievable and viewable over time.
  • A choice of two types of probe: optical probe or electrochemical oxygen measuring probe
  • Flow meter from 0 l/h to 300 l/h.
  • The user-friendly software is updated according to the latest designs.
  • The software can be used to set up an analysis, check its progress, prepare and produce reports, upload and edit previous analyses, and monitor the maintenance status of the equipment.
  • Export files are in .pdf and .csv format.
  • The instrument can be connected to and integrated with the company network via LAN or WI-FI connection, and monitored via mobile phone.
  • Automatic back-up in the event of shutdown due to external causes; the instrument is able to resume analysis and guarantees recovery of the data acquired up to shutdown.
