Transcript of Levapor Bio Film Technologies and Bio Consulting GmbH
About us
• We are Levapor Biofilm Technologies and Bio Consulting , GmbH.
• A specialized company providing innovative solutions for the treatment of wastewater and polluted air
• A team with more than 40 years of experience in research and development of fixed film based technologies for industrial and difficult to treat wastewater and polluted air
What We do • Problem analysis for the treatment of high strength
industrial and municipal wastewater treatment • Define treatment goals and conceptual process
design • Development of optimal process and parameters • Manufacturing of high performance tailor made bio
carriers for the application • Process Start up
Our Specialization • Anaerobic pre treatment of complex, persistent
industrial wastewater • Nitrification – De nitrification of effluents containing
inhibitory substances• Biological waste gas treatment using BTF(Bio
Trickling Filters) • Biofilm Reactor IFAS/MBBR for industrial and
municipal wastewater • Production and delivery of High Performance Bio
Carriers
Our Achievements • First full scale nitrification/denitrification plant for
ammonia rich effluents (1978) • Development of high performance bio carriers (1983) • Degradation of toxic effluents by anaerobic bio film
technologies (1985) • Design of full scale process for the anaerobic-aerobic
degradation of toxic effluents (1998) • Indoor bio treatment of polluted air for a ware house
of waste plastic (2002)
Industries We serve
• Chemicals and Pharmaceuticals• Petrochemicals and Refineries • Pulp and Paper • Coal Conversion : coke plant, coal gasification,
pyrolysis• Textile finishing and Leather manufacturers • Municipal Wastewater Treatment • Special effluents like land fill leachate and sludge
processing unit
Our Clientele• SAPPI , Germany : 20 MLD anaerobic-aerobic treatment
plant for treatment of high strength pulp and paper mill effluent
• City of Ningan, China : 22 MLD Municipal wastewater treatment plant for COD removal and nitrification
• City of Helsinki : Upgradation of existing municipal wastewater treatment plant
• Ludan Engineering, Middle East : Bio treatment of fine chemicals wastewater
• KERRY Intra, India : Bio treatment of container wash water
Our Technology
• LEVAPOR Bio Carrier • First synthesized Bio Carrier • Porous, Flexible, Durable PU foam
impregnated with surface active pigments with high surface area
• Due to variability of foam and pigment type and their ratios, tailor made carriers can be produced with varying properties
Our Technology
Unique Properties
PROPERTIES • High Adsorbing Surface
• High Porosity
• Fast wetting and water binding
• High surface Area • Higher fluidization ability
ATTRIBUTES• Adsorption of inhibitory
substances and fast colonization • Protection of biomass against
shear, anoxic zone formation • Homogenization of media and
maintenance of bio activity • Lower Degree of Filling (12-
15%)• Less Power consumption
Advantages • Reversible adsorption of inhibitory substances and slowly
bio degradable pollutants • Short process start up and higher performance compared
to suspended mass based systems (100 to 300%)• Colonization of carrier by more active bio mass and
simultaneous nitrification-de nitrification • Higher process stability and lower sludge yield • Lower degree of filling (12 to 15% compared to 40-65%
for plastic based media) • Remarkable lower power consumption compared to
conventional MBBRs
Applications• Up gradation/expansion of existing plants • Anaerobic-Aerobic treatment of high strength , slowly
bio degradable pollutants • Nitrification- de nitrification of effluents containing high
ammonia concentrations• Biological Treatment of Polluted air/gas (BTF)• Biofilm reactor MBBR/IFAS for the treatment of
industrial and municipal wastewater • Treatment of hyper saline effluents containing solvents • Treatment of land fill leachate and groundwater
containing PAHs.
Case Studies
• City of NINGAN Wastewater treatment Plant • Heilongjiang Province , China• 4,40,000 Population • Very Cold climate during winter • Difficulty in maintaining nitrification during
winter • Stricter Legal discharge limits

• Benefits:• 88-90 % COD and 91-93% NH4.N reduction despite
decreasing temperature and shorter HRTs• Remarkable process stability against temp, COD, TKN
variations • Lower level of nitrate confirming denitrification • Lower capital and operational cost
SAPPI,GERMANY• SAPPI EFFLUENT TREATMENT PLANT:• South Africa Pulp and Paper Industry, Ehingen, Germany • Sulfite based pulp and paper industry• Application of Chlorine for bleaching • High Concentration of toxic, weakly bio degradable
chloro-organic compounds • Strong Stream : COD 45 t/d @ 10 MLD • Weak Stream : COD 2.45 t/d @ 3.5 MLD
SAPPI,GERMANY
Lab scale testing Anaerobic or Aerobic?• Aerobic treatment with
suspended bio mass • Only 40-45 % COD
elimination • Anaerobic-Aerobic
Treatment ? • Anaerobic reactors using
different bio carriers
SAPPI,GERMANY
• 1 :Levapor • 2: Activated Carbon • 3: Unmodified PU foam • 4: Suspended Bio mass
SAPPI,GERMANY• Solution :• Anaerobic Treatment Using Levapor Carriers • Reactor Size only 15000 m3 instead of 65000m3 with
suspended bio mass • 1500 m3 of Levapor media • 66-70% COD removal • Further 50% of COD removal in Aerobic Treatment • 50,000 m3 less volume
SAPPI,GERMANY
Startup: 1990, only 2 of 3 ANA-reactors were started with LEVAPOR in order to compare the effect of immobilisation. After few weeks a toxic shock has stopped the reactor without LEVAPOR Nowadays: ~ 85 % COD- removal , 4 – 6 t/d sludge, 14.000 m³/d biogas
