Wastewater matrix and pollutant structure, conditions in biological reactor and the type of micro organisms present in the reactor are key responsible factors for efective biodegradation Toxic inhibitory efect of pollutants reduces growth rate of micro organisms and subsequent removal rate. Non flocculating micro organisms responsible for degradation are washed out from reactor reducing their activity and overall removal rate. Type of Micro Organism Strains available in the Bio-reactor Wastewater Matrix and its Physico Chemical Properties Chemical Structure of the Pollutants Local conditions: pH, Temperature, ORP Biodegradability of Industrial Efuent THE SOLUTION Using modern biotechnology tools, the problems can be solved. Live and active micro organisms responsible for the degradation of refractory and toxic pollutants can be retained and allowed to grow in the biological reactor achieving efcient degradation and lower COD values of treated efuents. Development, Retention and Protection of highly specialized micro organisms/strains in the reactor with the help of micro cell immobilization on ideal carriers Presence of Active Micro Organism strains responsible for the biodegradation of the wide range of pollutants present in the efuent Reactor design and maintenance of optimal process conditions for the ideal growth of micro organisms in the reactor Optimal biological treatment of industrial efuents

2. LEVAPOR CARRIERS An Ideal Habitat for the Microbial Strains degrading refractory pollutants Due to impregnation of hydrophilic PU foam having fine pore structure with Activated Carbon, Levapor carriers provide very high adsorbing capacity and inner porosity for the immobilization of micro organisms on it. The micro organisms get colonized on it not only in biofilms but also in clusters of individual colonies allowing retention of even the non flocculating organisms responsible for the overall biodegradation of refractory pollutants. Pollutants Adsorb on Activated Carbon Biofilms Also adsorption and degrading the pollutants and thus regenerating the surface Levapor Carrier surface LEVAPOR CARRIERS COLONIZED WITH 3-CBA DEGRADING MIXED CULTURE REVERSIBLE ADSORPTION AND DEGRADATION ON LEVAPOR CARRIERS REVERSIBLE ADSORPTION AND DEGRADATION A UNIQUE FEATURE OF LEVAPOR CARRIERS Due to its impregnation with activated carbon, Levapor carriers allow adsorbing of toxic organic pollutants, reducing their bulk liquid concentration and thus counteracting the toxic efect on the micro organisms active in suspended phase. Simultaneously the carrier surface also provides habitat for the growth of micro organisms degrading the adsorbed pollutants and thus regenerating the surface causing “reversible Adsorption and Regenera- tion” a unique feature of Levapor carriers BIODEGRADATION OF 2CA ON LEVAPOR CARRIERS THROUGH REVERSIBLE ADSORPTION AND SUBSEQUENT BIODEGRADATION Addition of Levapor reduced 2CA concentration in liquid After colonization, Cl ion released which confirmed the biodegradation LEVAPOR ADVANTAGES FOR THE BIODEGRADATION OF TOXIC REFRACTORY POLLUTANTS Reduced Toxic and inhibitory efects due to presence of Activated Carbon Protection of Micro Organisms within inner pores Retention of Highly Active Biomass responsible for the degradation of the pollutants Remarkably higher degradation of refractory pollutants reducing outlet COD value Higher Process Stability and degradation of a wide range of pollutants present BIOFILM-TECH GmbH 25, Wilhelm street Bonn, D-53111 LEVAPOR INDIA PVT.LTD.
