Iron hydroxides causing turbidity and silting will strongly affect the river Spree for many decades. In addition to liming acidic surface waters and the conventional treating of mine waters, microbial sulphate reduction of the inflowing anoxic AMD groundwater is tested for long-term remediation. During a pilot project at the location 'Ruhlm{\"u}hle' in north Saxony since end of 2014 glycerin as a carbon source and nutrient solutions of N and P are infiltrated in an anoxic AMD groundwater stream by lances ([1]). Planning and operation were carried out based on a model. The complex reaction mechanisms in the aquifer were formulated using phreeqc2. They were applied to the flow path from the infiltration to the measuring points as a mixed cell model. Based on literature research as well as laboratory experiments and pilot tests ([2], [3]), the biochemistry of the sulphate reduction was drafted as an extensive reaction term refined by adaption to experimental results later on. To describe the sorption processes on the solid matrix of the aquifer, the surface 'Sandw_OH' had to be defined and parameterized. The behavior of metabolites and humic substances could only be considered with the aid of new reaction models. On the basis of intensive preliminary investigations, the mixed cell model developed for the pilot sites can be applied to other glacial aquifers. Moreover, it was possible to elucidate numerous side reactions and to describe them in the model. Ultimately, the process of sulphate reduction is available for the treatment of groundwater containing high amounts of products of pyrite weathering. It can be applied at the source as well as on the flow path. Design and control of the variety of overlapping processes is only possible by means of the developed model approaches.}, language = {en} } @misc{KuhnVornholtPreussetal., author = {Kuhn, Ramona and Vornholt, Carsten and Preuß, Volker and Bryant, Isaac Mbir and Martienssen, Marion}, title = {Aminophosphonates in Nanofiltration and Reverse Osmosis Permeates}, series = {Membranes}, volume = {11}, journal = {Membranes}, number = {6}, issn = {2077-0375}, doi = {10.3390/membranes11060446}, pages = {1 -- 16}, abstract = {Aminophosphonates such as aminotris(methylenephosphonic acid) (ATMP) are common constituents of antiscalants. In nanofiltration (NF) and reverse osmosis (RO) processes, ATMP prevents inorganic scaling leading to more stable membrane performance. So far, little attention has been paid to the possible permeation of aminophosphonates through NF and RO membranes. We have investigated the permeability of these membrane types for ATMP and its potential metabolites iminodi(methylenephosphonic acid) (IDMP) and amino(methylenephosphonic acid) (AMPA) with two different NF membranes (TS40 and TS80) and one RO membrane (ACM2) and three different water compositions (ultra-pure water, synthetic tap water and local tap water). We found traces of phosphonates in all investigated permeates. The highest phosphonate rejection occurred with local tap water for all three membranes investigated. Filtration experiments with a technical antiscalant formulation containing ATMP indicated similar trends of phosphonate permeability through all three membranes. We assume that the separation mechanisms of the membranes are the results of a very complex relationship between physico-chemical properties such as Donnan exclusion, feed pH, feed ionic strength and feed concentration, as well as solute-solute interactions.}, language = {en} }
