QS

QS is referring to Quorum sensing, a technical term …

….. meaning the capacity of protozoa to measure the cell density of a population by chemical communication. This is an important principle, used by bacteria to coordinate processes that would be inefficient if only done by single cells. So by doing this, they are able to adapt the reproduction rate, forming biofilms and simply, whether to work more (under stress) or work less (without stress). 

Understanding the process

In biogas plants it is of significant interest to have an efficient degradation and to ensure the process´stability towards stress, like bio-chemical intermediates, that emerge from degradation processes (e.g. toxic products of protein degradation, accumulation of volatile fatty acids) or dependent of temperature, the composition of the feeding and the supply of micronutrients.

Facing the challenge

An increase of Input of hardly digestible organic material often comes along with an increase of the organic load and challenge for microorganisms to adapt and to grow fast. 

Keep the control

QS Biogas Service already understand some of it and provide this experience in an approved biological and technical consulting. See laboratory services. 

Our working field includes:

  • Biological support of facilities by laboratory analysis, gas yield tests, methane bacterial screening (qPCR) and special products for the biological process
  • Consulting, sales and implementation of Suprajet®, a fiber extrusion technology by cavitation
  • Biological and technical process optimization by determining hydraulic properties in digesters, flow analysis and agitation management
  • Profitability and substrate management. Advice on refinancing and investment measures, input strategies and input alternatives

Flow physics evaluation and agitation management

This is our most interesting project and under practical use now in a 500KW biogas plant. It is about a device that transmit data from the inside of

the digester. With a special marker and lance-shaped sensors, going inside the digester´s wall, it tells us about internal sedimentation and layer structure and makes these data visually kept in a software model. By doing this, we will be able to understand the moving of material in the digester to detect dead zones, low and high temperature areas and deficient agitating and feeding techniques.Traxmon

We already offer a floating ball (traxmon® wireless sensors), that transmit temperature from the surface of the digester to your mobile phone. This device consists of a wireless chip and a receiver, collecting data for approx. 2-3 month. It provides online data, simultaneously featured in a diagram, telling about the correctness of the facility´s sensors (mostly measured near the concrete wall), or wether the temperature distribution is OK. Interesting is to know if the digester is vulnerable to changing climate, feeding or feeding intervals.

Methana ProBios® Additive for strengthening facultative methane bacteria

+Why supporting the digester´s biology?

Every Biogas process is determined by underlying conditions, like composition of feed, nutrients, temperature, pH level etc. and thus forming an unique community of bacteria: With specialists and generalists, fast and slow, „lone fighters“ and those who work in a team. All this might slow down the biogas process, because it is a complex long way to our end product CH4. To improve this and for a faster degradation hence it is necessary to support certain degradation steps additionally – apart from nutrition and basic knowledge of fermentation processes.

+How?

Stimulating bacteria´s metabolism and activity in order to get a higher reproduction rate in bacteria´s population and thus more enzyme secretion. You can achieve this by our additive Methana ProBios. Additionally more bacteria mass reduces the vulnerability towards stress factors like ammonia, H2S, toxins or changing conditions (feeding, temperature, etc).

By using ProBios all biological processes go faster, so the degradation rate is increasing. Biogas plants with high loading rates, or slowly degradable substrate (like high fiber or protein content) benefit from it.

Methana ProBios® comes in liquid form, 20l HDPE cans. Non hazardous or toxic.

Gas leaks

With a modern IR camera we make a 1-2 hour visit on your facility and detect gas leaks with out interrupting any production. Only by checking the back coming air from the outer roof, we need to stop the blower.

In the moment we offer regional schedules to connect nearby facilities to be able to reduce travel costs.

An actual overview about the economic impact of methane leaks, authority´s guidances and how to fix leaks: Please write us an email in the contact box. We try to provide you actual information.

1-2 hours on-farm visit, detecting and marking, discussion. No expertise report, only evaluation matrix according QMab.

Biogas for household use

Early last year the project of a small size biogas plant for normal households started. The principal idea was to reduce organic waste fraction in the daily waste bin and secondly having biogas for heating and cooking. Many modern households especially in the cities are not encouraged to separate the organic fraction, so it´ll be dumped together with the normal waste. In really encouraged families, they use to bring it to the public container, but often are faced with the bin´s „vitality and odors“. By using the food waste for the biogas production the digested output is more easy in handling and can be stored as concentrated fertilizer. The growing number of vegetarians also indicates, that the waste bin is getting filled more and more with vegetable waste.

The household biogas process can be compared with an aquarium from the working intensity and knowledge point of view. You need to care about the biological process like you care for water quality and reproduction of your breeding fish. If bacteria doesn´t like the conditions (food waste amount and composition, temperature, biological parameters, mixing) it will not die immediately, but will reduce or stop working properly and production is not satisfying. Once the process is ill you need to know how to react and reactivate biology. Like in every biological process this cannot happen immediately.

But with the attitude of a sustainable and ecologic thinking entrepreneur, you will learn how to reduce electricity costs and love to contribute to self- sufficiency.
