THOLANDER ABLUFTTECHNIK GMBH - Helping the world breathe easily again

Due to its process-integrated biological degradation, the biofilter is an incomparably cheap and efficient procedure for odour removal and the treatment of low concentrated or undefined air flows. This advantage lies in the natural decomposition of air pollutants into harmless products. Incomparaply cheap technique Simple process technology Operation through permanent staff of the operator Advantage through the natural reaction conditions of the catabolism Flexible concept Reduced operating costs regarding Energy consumption Water consumption and effluent water Use of chemicals Maintenance efforts Long-lasting construction Plant components of corrosion resistent and chemical resistant materials Biologically active filter material High inner surface for the settlement of microorganisms Steady perfusion Good drainage impact Integrated pre-scrubber Dampening of the air until saturation Stripping of pollutants through the microflora for an optimal operation Dosing of various...

Benefit from the advantages of the biofilter and of the counter current scrubber in one single system. Thanks to the high specific surface of the packing material and thanks to a controllable irrigation a demanding concentration of contaminants like H 2S can be treated in a compact system. Cost-effective Space-saving construction that can be built into height No filter material exchange Microorganisms settle at inert materials Low running costs with high concentrations of contaminants Easy to maintain user interface Controllable milieu conditions Regulation of water supply Dosing of mineral nutriments Automatic pH-control Automatic desalination Well-thought-out conception Self-cleaning measuring probes Low pressure drop Low risk of clogging Durable construction Plant components made from corrosion and chemical resistant materials 30 years of experience Active references of each size Worldwide delivery, installation and service

Counter current scrubbers offer a competitive solution for "single substance problems". With our design we can ensure that contaminants will be removed efficiently from the waste air. Efficiency Little space requirements Separation result > 99% with heavily loaded waste air Little pressure drop because of heavy-duty packing material Easy to maintain user interface Dosing of chemicals as needed Optimized energy consumption Reliable and fully automated operation Level switch in pump sump Dry run protection Control of nozzle pressure Automatic, data controlled chemical dosing Automatic desalination Frost protection for outdoor installation Well thought out design Little pressure drop Little risk of clogging through choice of right packing material Plant made of corrosion-resistant and chemical-resistant FRP Big flexibility Optimized for varying raw gas loads No adjustment phase 30 years of experience Active references of each size Worldwide delivery, installation and service

Our crossflow scrubber reaches an optimum of flexibility. By flowing through various scrubbing stages consecutively, dust, acid or alkaline substances are removed within one plant. Flexibility Adaptation to your complex waste air Multiple stages in one housing Simultaneous elution of different contaminants Low construction height without waste loss Scrubbing stages sind nicht baulich getrennt Easy to maintain user interface Optimal consumption Efficient supply of fresh water Optimal dosing of chemicals Low pressure drop and low pump duty Reliable and fully automated operation Level switch in pump sump Dry run protection Monitoring of nozzle inlet pressure (Düsenvordruckes?) Fully automated, measurement driven control of chemical dosing Automatic desalination Frost protection for outdoor installation Low risk of clogging by choice of the right packing material Durable construction Plant components made of corrosion and chemical resistant FRP 30 years of experience Active...

Multiventuri scrubbers are suitable for the separation of adhesive aerosols and for fine dust in humid waste air as these filtrating separations lead to adhesion, clogging and thus to irreversibel high filter resistance. In a wet separating process, the particles are washed out and thus cannot adhere. Reliable and automatic operation Automatic elutriation Automatic washing of separated elements Automatic discharge of the Ausschleusung der nicht absetzbaren ölhaltigen Stäube Level switch in pump sump Dry run protection Control of the nozzle inlet pressure Frost protection for outside installation Advantages Suitable for hot waste air Easy to maintain user interface Big flexibility with unsteady raw gas load Compact execution Durable construction Plant components made of corrosion and chemical resistant FRP 30 years of experience Active references of each size Worldwide delivery, installation and service

Waste air purification with a wide range of applications achieving extremely low clean gas values also at low residual concentrations. Odor-intensive pollutants like H 2S, Mercaptanes, VOC etc. are being removed due to the high loading capacity of the activated carbon. Easy process technology universal applicability multiple in-situ regeneration possible no additional energy consumption low pressure drop because of hard and abrasion-restistant activated carbon High purification efficiency even with high moisture content until air moisture of 98% well-suited for humid air from sewerage and wastewater treatment plants Reasoned concept manholes for infilling or exchange sampling tube for measurement of loading of activated carbon Long lasting construction plant components made of corossion and chemical resistant materials 30 years of experience Active references of each size Worldwide delivery, installation and service
