analytics, fermentation tests, pilot plant experiments
We examine your natural and residual materials and check all treatment steps in the laboratory and technical center
We at GNS offer you comprehensive laboratory services relating to the use of biomass and waste recycling. Our laboratory specializes in testing biogas plants and fermentation residues, as well as analyses in the areas of wastewater, residues and fuels. Fermentation tests and residue analysis are among the regular testing tasks we carry out on behalf of our customers.
Research and development laboratory – our comprehensive laboratory services
In our laboratory and technical center we carry out analyses and test setups individually according to your needs, such as
Mechanical and physical-chemical separation of substances
recovery of valuable materials
treatment of waste materials and industrial wastewater
immobilization of pollutants
Biochemical and thermochemical treatment processes
Analysis of deposits in e.g. pipes
proof of compostability
Through process simulations in the laboratory and pilot plant, we can test process engineering solutions and thus obtain important data for the design of technical systems. With our versatile laboratory equipment and extensive practical experience, we achieve a high level of flexibility in meeting your requirements.
Our services for biogas plants
We offer analyses and investigations to control process biology, biogas substrates and fermentation residues as well as fermentation residue treatment. Discontinuous and continuous test systems with reaction volumes between 0.25 and 10 liters are available for this purpose.
Substrate Characterization and Evaluation
Batch fermentation tests and continuous fermentation tests according to VDI 4630
Investigations into the elimination of inhibitions in the fermenter by ammonia or hydrogen sulphide
Investigations into improving the digestion of substrates
Investigations into the recovery of nitrogen and phosphorus from digested sludge and fermentation residue by stripping, flocculation and precipitation combined with mechanical separation operations
Would you like to use the services of our laboratory or do you have questions about the possibilities of an analysis? Then our experienced team will be happy to assist you personally. We will give you expert advice.
