Projects oriented to the generation of energy using anaerobic digesters with generation, cleaning and safe use of biogas are offered.
Biogas, which is a product of the anaerobic degradation of the organic matter of wastewater, is an effective source of alternative energy. Before being used, biogas must be treated to remove particles of solids, moisture, H2S and even CO2 (depending on the case). Biogas can be used to generate electricity and/or heat.
IBTech® has its own technology for the integration of biogas cleaning and reuse systems based on biological and/or physicochemical processes.
The generation of odors is one of the main problems associated with wastewater treatment plants and in some cases, is decisive to close or prevent their installation.
The source of these odors is related to the generation and treatment of solid waste as biological or chemical sludge, likewise to the wastewater handling itself and to the degradation of the organic matter inside the plant, so that it is difficult to avoid their generation.
There are several methods for odor control. One of the most efficient and cost-effective is the compost biofilter, which is based on the interaction gas-organic medium. The organisms that live and develop in the biofilter degrade bad odors.
The main component of the biofilter is the biological filter media (mixture of natural materials), which has the necessary surface to carry out the absorption and adsorption of odor-causing compounds. The bad odors and the nutrients of the media will propitiate the growth of a biofilm, which as it develops and by effect of its metabolic activity will leave the gas free from bad odors.
The scrubber is used to remove contaminants from gaseous emissions. For this, contaminated gas is introduced through the lower part of the column and circulated towards the upper part. On the other hand, the washing liquid is introduced at the upper part and it is distributed over the column to absorb the contaminants and thus wash the contaminated gas.
To carry out the above, the column has a packing where chemical reactions occur. In other words, it is where the contaminated gas receives treatment and pollutans are removed. The purpose of the packing is to ensure a large contact area to allow a high rate matter transfer while maintaining a minimum pressure loss and fouling.
Packing selection depends on several factors, both technical and economical in which the best price/performance ratio is desired
The packing should be selected for a particular fluid, gas load and elimination rate desired. In addition, the packing height should be carefully calculated based on the treatment goal.
The packing material can be ordered or random; besides, it can be plastic, metal or ceramic.
The gas scrubber has several applications, among which are:
