About
atres solutions, led by founder Dipl.-Ing. Gunther Pesta and headquartered in Munich, Germany, specializes in anaerobic technology and renewable energy systems for biogas plants and biological wastewater treatment. Founded in 2006, the company name derives from Anaerobtechnik und regenerative Energiesysteme. ATRES operates through two brands: ATRES Group provides trace element formulations, desulfurization products, mobile spectroscopy instrumentation, and consulting for biogas operators; atres solutions targets biological wastewater treatment for the food and beverage industry. The company is an accredited specialty laboratory for biogas analysis, operating a pilot plant and technical center at Freising-Weihenstephan. The atres c-plus trace element product line includes five organic chelate complex formulations — Universal, Spezial, Selen, Stickstoff-angepasst, and Bio-Qualität — manufactured by an ISO 9001:2000 certified partner, all REACH conformant. Additional products include atres Ferrox PLUS desulfurization product with over 65% iron content for hydrogen sulfide removal, atres EXodeur microbiological additives for odor control, atres ZYmix biochemical catalysts for process enhancement, the atres OptiMIRS mobile mid-infrared spectrometer for on-site analysis of fatty acids and ammoniacal nitrogen in 90 seconds, and atres SR-20/SR-30 specialty cleaners for solar, heat pump, and HVAC applications originally developed with DAIKIN. ATRES also provides comprehensive process consulting from planning through commissioning and operational optimization.
Key Products
Essential trace element formulation for biogas plants and anaerobic wastewater treatment, using organic chelate complexes for high biological availability to support healthy microorganism development and efficient fermentation.
Specialty trace element formulation with additional ingredients for rapid compensation of deficiency symptoms or quick reduction of volatile fatty acids, used for initial dosing, startup, or emergency interventions in anaerobic processes.
Selenium-specific trace element formulation for anaerobic digesters with pronounced selenium deficiency, enhancing enzymatic activity and hydroxygenases for efficient substrate breakdown.
Nitrogen-adapted trace element formulation for high nitrogen load applications such as poultry manure and chicken droppings as primary substrate, maintaining adequate trace element supply while managing ammonia stress.
Organic-certified variant of the c-plus trace element formulation with corresponding organic certification for use in certified organic biogas and wastewater treatment operations.
Professional microbiological additive described as a microbiological power plant for biological wastewater treatment, addressing odor issues and improving biological process stability.
Professional biochemical catalyst for biological wastewater treatment, enhancing process efficiency and microbial activity in anaerobic and aerobic treatment systems.
Powdered desulfurization product with over 65% iron (Fe) content for biogas plant hydrogen sulfide removal, available in 20-kg bags, 500-kg, and 1000-kg big bags for easy handling and high availability.
Mobile mid-infrared spectrometer using attenuated total reflectance for on-site analysis of fatty acids, ammoniacal nitrogen, and other parameters in 90 seconds, with over 5,000 hours maintenance interval, delivered with tablet PC, software, calibration models, and consulting.
Multitasking digital ballpoint pen for efficient data capture and rapid digitization, designed for field and laboratory recording in biogas and wastewater treatment operations.
Mild, material-friendly specialty cleaner for solar collectors, heat pumps, and air conditioning units, originally developed for DAIKIN indoor AC units and in use since 2015.
Second specialty cleaner in the SR product line for solar, heat pump, and AC maintenance, with the same applications as SR-20.
Accredited specialty laboratory at Freising-Weihenstephan providing chemical-technical analyses for biogas plants and anaerobic wastewater treatment process monitoring.
Microbiological process monitoring and consulting services covering planning through commissioning, operation, expansion, and efficiency optimization for biogas and anaerobic treatment facilities.
Access to pilot plant and technical center at Freising-Weihenstephan for bench- and pilot-scale R&D testing of anaerobic processes and treatment optimization.
