  1. 6. Idealised remediation scenario in two small-scale intersecting fractures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Agnes Zúniga Ekenberg; [2022]
    Keywords : ;

    Abstract : Analysis of mass transport in rock fractures has become increasingly important in underground storage of radioactive materials and remediation of polluted groundwater in fractured rock aquifers. Permeability of rock mass is regulated by present rock fractures, where flow is mainly through the fracture networks. READ MORE

  3. 7. Life Cycle Assessment of a small scale, solar driven HVR water purification system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sharang Kolathur; [2022]
    Keywords : life cycle assessment; air gap membrane distillation; solar energy; levelized cost; grid operated system; livscykelanalys; luftgapmembrandestillation; solenergi; utjämnade kostnader; nätdrivet system;

    Abstract : Water purification systems have made access to drinking water easier by treating water sources which previously could not be used for drinking. Such systems however require energy and materials to build and operate which means they have environmental impacts. READ MORE

  4. 8. Groundwater flooding in a Moldovan limestone mine : An investigation into the limestone aquifer in Chisinau andsustainable solutions to mine dewatering

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Erik Tobin; [2022]
    Keywords : groundwater; hydrogeology; limestone; mine; Moldova; Chisinau; grundvatten; hydrogeologi; kalksten; gruva; Moldavien; Chisinau;

    Abstract : This work aimed to investigate the groundwater situation in and around Mina din Chisinau, an underground limestone mine in Chisinau, Moldova, in order to contribute to a sustainable solution to its flooding problem. Work on-site was done including visits inside the mine, to points of hydrogeological relevance to the mine, well inventories/search, and an attempt at an infiltration test. READ MORE

  5. 9. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ebba Pegestam; [2022]
    Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  6. 10. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material

    University essay from SLU/Dept. of Soil and Environment

    Author : Oscar R. Davies; [2022]
    Keywords : Hjältevad; zerovalent iron; phosphate extraction; Oxalate extraction; Visual MINTEQ; geochemical modelling;

    Abstract : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. READ MORE
