Retrofitting work chemicals

Chemical repairing reinforcement technology is a new type of reinforcement and reconstruction technology for reinforced concrete structures. It not only has the characteristics of convenient construction, small working face and high working efficiency, but also has the advantages of strong adaptability, wide application range, good integrity of anchorage structure and low cost.

The system treats a gas flow rate of around 50,000m3/h, with average concentrations of volatile organic compounds, NH3 and H2S, of around 10, 2, and <1 ppmv, respectively. The main actions undertaken during the conversion were the substitution of the recirculation pump and of the packing material and the modification of the makeup water and purge flow controls. Afterward, the reactor was inoculated with sludge obtained from a wastewater treatment facility and immediately started up as a trickling filter.

No significant operation issues were observed during the operation period, other than pH variations and a slight increase in pressure drop, proving that the biotrickling filter is a highly robust system. Relatively low removal efficiencies around 10 and 25% were found, for the volatile organic compounds and NH3, respectively. However, due to the low empty bed residence time, these corresponded to notable elimination capacities of around 18gC/m3h and 3gN/m3h. No nutrients were supplied to the bioreactor during the first 5months of operation other than those contained in the sludge employed as inoculum.
