Ammonium and Phosphate Recovery from Biogas Slurry: Multivariate Statistical Analysis Approach
نویسندگان
چکیده
Livestock biogas slurry is an effluent containing nutrients such as ammonium and phosphate that are released by the industries. Therefore, recovery reuse of phosphorus highly necessary. In recent years, many studies have been devoted to use different multivariate statistical analyses investigate interrelationship one factor another factor. The overall objective this research study was understand significance from using approach. This conducted a range salts commonly found in (ZnCl2, FeCl3, FeCl2, CuCl2, Na2CO3, NaHCO3). Experiments with digester aqueous solution were at pH 9, integration NH4+, Mg2+, PO43− molar ratios 1.0, 1.2, 1.8, respectively. removal efficiency increased 15.0% 71.0% 18.0% 99.0%, respectively, increasing dose respective ions K+, Zn2+, Fe3+, Fe2+, Cu2+, CO32−. elements 58.0 71.0 for HCO3−, concentration 30 mg L−1 240 L−1. Principal component, regression, path analysis, Pearson correlation used relationships under biochar, pyrolysis temperature, element efficiencies. Multivariate analysis also comprehensively evaluate biochar struvite effects on slurry. results showed combined statistics suggested all indicators positively or negatively affected each other. insignificant ionic concentrations, more than significant 0.05. concluded type, varying levels components, CO32−, had substantial impact P NH4+ recovery. Temperature amounts metal enhanced efficacy elucidated methods which effectively reuses nitrogen slurry, presenting long-term agricultural solution.

Classical multivariate statistical methods concern models, distributions and inference based on the Gaussian distribution. These are the topics in the first textbook for mathematical statisticians by T.W. Anderson that was published in 1958 and that appeared as a slightly expanded 3rd edition in 2003. Matrix theory and notation is used there extensively to efficiently derive properties of the m...
متن کاملAnalysis of factors affecting perinatal mortality. A multivariate statistical approach.
Despite important progress during recent decades, perinatal mortality is still a problem of major national importance. Today nearly 3 per cent. of all births result in perinatal death. To reduce this loss requires a better understanding of the way in which a large number of inter-related social and medical factors influence perinatal mortality risk. We are developing a series of studies to sepa...
متن کاملBiogas Production and Nutrient Recovery from Waste Streams
Waste streams such as municipal wastewater and animal manure contain organic materials and nutrients that can be converted and recovered for bioenergy and renewable fertilizer production. In the first part of this thesis, the anaerobic co-digestion of dairy manure with kitchen waste and chicken fat was studied for the purpose of increasing biogas production. The methane yields of co-digestion s...
