  1. 1. Considerations and Novel Technologies in Industrial Water Treatment - Treatment of challenging wastewater

    Master-uppsats, KTH/Kemiteknik

    Författare :Nils Toll; [2021]
    Nyckelord :Industrial water treatment; considerations; novel technologies; BOD; COD; organic waste; heavy metals; desalination; Industriell vattenrening; nyckelfaktorer; nya teknologier; organiskt avfall; tungmetaller; avsaltning;

    Sammanfattning : Industriell vattenrening är ett extremt viktigt område inom Miljöskyddsteknik då 60% av allt sötvatten inom Sverige används av industrier. Substanser som PFAS, aromatiska textilfärger, fenol och läkemedelsrester är extra utmanande då dessa kan vara gifta för biologisk rening. LÄS MER

  3. 2. Modeling BOD removal in free watersurface constructed wetlands with variable residence time-based methods

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Degefu Yohannes Sebro; [2021]
    Nyckelord :BOD removal; Free water-surface constructed wetlands; VART-BOD; models; dynamic diffusion zone; Technology and Engineering;

    Sammanfattning : Constructed wetlands (CWs) have been applied for several years in the removal process pollutants from secondary treatment plants and stormwater. In this paper, the Variable Residence Time (VART) model for solute transport in streams was extended to simulate the BOD removal process in free water surface flow constructed wetlands (FWS CWs).

  4. 3. Assessment of on-site wastewater treatment systems in unsewered communities in Jordan

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Hani Yahya Ali Shubail; [2020]
    Nyckelord :Constructed wetland; Decentralized wastewater treatment; Jordan; On-site wastewater treatment system;

    Sammanfattning : Centralized wastewater treatment systems need substantial funds besides high-cost operation and maintenance programs, which could be considered unsuitable for low-income developing countries. As a solution, it becomes the trend towards on-site wastewater treatment systems (OWTs) due to its cost-effectiveness and flexibility of implementation and management. LÄS MER

  5. 4. The possibilities of recycling wash water at Vidinge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Julia Mauritzson; [2020]
    Nyckelord :reuse; treatment; fresh-cut; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Sammanfattning : Water is a resource of importance and with drier weather around the world, including Swe-den, there is a risk of too low levels of water to satisfy for instance households, animals and industries in the future. Fresh-cut fruit and vegetable industries are water intense and almost all process water is used in the washing process. LÄS MER

  7. 5. EFFECTS OF PLANT HARVESTING ON NUTRIENTS REMOVAL IN CONSTRUCTED WETLANDS.

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Elvanus Kapira; [2017]
    Nyckelord :;

    Sammanfattning : Insufficient access to clean water and sanitation has become one of the most universal problems affecting human health in developing countries, water resources are facing high pollution rate due to improper management of wastewater. Ecological technologies such as constructed wetlands are promising innovative solutions for this universal problem. LÄS MER
