“…Furthermore, an increase in the air flow resulted in a process efficiency reduction. The cited authors defined the increasing production of foam and the formation of calcium hydroxide as a cause of this observation [37].…”

“…However, raising the pH value with lime to 10.5-11.5 results in the deposition of calcium carbonate. Nevertheless, stripping has been successfully used for the treatment of wastewater with a large load of ammonium ions, both for leachate from landfills and oil refineries, or effluents from the anaerobic digestion of pig, cattle and chicken manures [29,37].…”

Purpose This study aimed to examine the possibilities of the treatment of the by-products generated in the anaerobic digestion (AD) of the organic fraction of municipal solid waste (OFMSW): oxygen stabilization (composting) of the solid digestate and pretreatment with air stripping of the effluents (liquid digestate and leachate from maturation field and reactors from composting). Methods Oxygen stabilization (OS) was performed in full-scale in a mechanical-biological treatment (MBT) plant using three different methods, using an open field or enclosed box reactor with aeration. The ammonia stripping was performed in a pilot-scale installation using effluents from AD (liquid digestate) and OS (leachate from maturation field and reactors). Results The lowest self-heating possibility after the OS was recorded at 28.5 °C, which proves that the most stabilized was the sample after processing with structuring material addition. Due to air stripping, the highest efficiency of ammonium ions removal was noted at the level of 50.6%, with an initial pH value of 10.5, after 12 h. Among the examined factors pH value was found to be significant [the determination coefficient (R 2) of 0.93]. Conclusions The oxygen stabilization of the digestate requires the structuring material addition before being placed in the reactor with aeration. The inert fraction from the ballistic separation of the OFMSW can be an interesting solution, as required structuring material. Air stripping as the effluents pre-treatment step can meet the MBT plants expectations.

In this assay, rabbit anti-β-conglycinin polyclonal antibody (Pab) was used as primary antibody and goat anti-rabbit IgG-horseradish peroxidase (HRP) was used as secondary antibody. The optimum incubating time of blocking, HRP and TMB (3, 3'5, 5'-tetramethylbenzidine) detected by the response surface and orthogonal test was 58, 140, and 20 min, respectively. The practical working range for the determination of β-conglycinin was 20-320 ng ml −1 . The recoveries of β-conglycinin in spiked soybean samples were between 95.8 % and 101.2 % with the relative standard deviation less than 6.9 % (intraassay) and 8.2 % (inter-assay). The current method was used to analyze 80 different soybean obtained from different region of Jilin province and the detected results using the direct ELISA. Compared with the competitive ELISA, The results showed contents had no difference between two methods. The dcELISA assay provides a specific and sensitive method for detecting of soybean β-conglycinin in actual production.
