dcterms:description
In recent time, there have been many approaches to eliminate hydrogen sulphide from the biogas that are based on physical and chemical processes. These technologies are relatively expensive and associated with the need for replacement or regeneration of adsorption substance, washing liquid, large consumption of chemicals, etc. The interesting branch is the approach based on the application of biological agent (SOB). This project aims to supplement the offer of additional equipment in the biogas station by the biological system through which it will be possible to reduce the hydrogen sulphide with conversion into sulfur or sulphates. Two-stage system consisting of scrubber and bioreactor was suggested. Polyether foam Filtren (Eurofoam TP) with defined pore size and polyethylene carrier 2H-BCN 030 (GEA 2H Water Technologies) were selected as carriers for commercially available desulphurization equipment. Water from treatment plant was used as a washing liquid in scrubber. Sufficient amount of microelements was provided by adding liquid share of digestate from biogas station (10 % v/v). The following bioreactor sizes are designed for biogas station with an average daily production of biogas 2,000 m3/day with an average concentration of 2500 ppm hydrogen sulphide. From the experiment result, the removal rate of sulphides and the facility capacity for biomass concentration 1 g.l-1 were calculated; the removal rate 1,080 g.m-3.day-1 (1,344 sulphides g.m-3.day-1) and facility with a capacity of 5.94 m3 (4.77 m3) for the suspension system, resp. biofilm system.
