The Anaerobic Digestion industry tends to spend too much time scrubbing the biogas, when in most cases, a far better solution to producing a better quality of gas, is to tackle such problems at the source of the problem, in the digester. By doing it in the digester there are so many spin-off benefits. In fact, operators will end-up wondering why they did not previously pursue all avenues for optimizing the conditions in the reactor to suit the micro-organisms they want to encourage!
A policy of H2S prevention, combined with the avoidance of high (and biochemical process inhibiting) ammonia concentrations, not only helps to stabilise the whole methane production process, it also allows the healthier biomass that results, to produce more gas of a better quality. This is achieved, it is understood, without changing the feedstock, and occurs over a period of time.
This looks like a true “win-win” situation, and involves the daily dosing of the digester with Deuto-Clear® Sulfo. This according to the Lukeneder brochure:
"Is a ready-to-use solution containing metal salts and trace elements. It improves the performance of your biogas plant and its dosage will be adjusted to fit the specific needs of your digester. Deuto-Clear® Sulfo features a broad range of trace elements, minerals, and other agents to improve the quality and stability of the digestate."
Deuto-Clear® Sulfo removes hydrogen sulphide and ammonia gas from the digestate and adds nutritious trace elements and minerals to produce a healthy and productive environment for anaerobic bacteria.Added benefits are listed as:
- HOMOGENISATION OF FERMENTATION SUBSTRATE
- QUALITY OF FERTILISER IS IMPROVED AS AMMONIUM
- AND SULPHUR COMPOUNDS ARE BOUND IN THE DIGESTATE
- NO LONGER NECESSARY TO DOSE WITH OXYGEN TO CONVERT H2S.
