  • Faeces - Urine separation via settling and displacement: Prototype tests for a novel non-sewered sanitation system 
    Hennigs, Jan; Ravndal, Kristin T.; Parker, Alison; Collins, Matt; Jiang, Ying; Kolios, Athanasios J.; McAdam, Ewan; Williams, Leon; Tyrrel, Sean F. (Elsevier, 2020-08-23)
    The development of novel, non-sewered sanitation systems like the Nano Membrane Toilet requires thorough investigation of processes that may seem well-understood. For example, unlike the settling of primary sludge, the ...

    A prototype of a non-fluid based mechanical toilet flush was tested in a semi-public, institutional setting and in selected peri-urban households in eThekwini municipality, Republic of South Africa. The mechanism's ...
  • Menstrual hygiene management and waste disposal in low and middle income countries — a review of the literature 
    Elledge, Myles F.; Muralidharan, Arundati; Parker, Alison; Ravndal, Kristin T.; Siddiqui, Mariam; Toolaram, Anju P.; Woodward, Katherine P. (MDPI, 2018-11-15)

  • Starch degradation and intermediate dynamics in flocculated and dispersed microcosms 
    Ravndal, Kristin T.; Kommedal, Roald (IWA Publishing, 2017-08-16)
    A large fraction of the organic substrate in municipal wastewater is particulate. Prior to uptake, particles have to be degraded through potentially a range of intermediates. However, research on intermediate dynamics ...
  • Wastewater characterisation by combining size fractionation, chemical composition and biodegradability 
    Ravndal, Kristin T.; Opsahl, Eystein; Bagi, Andrea; Kommedal, Roald (Elsevier, 2017-12-18)
    The potential for resource recovery from wastewater can be evaluated based on a detailed characterisation of wastewater. In this paper, results from fractionation and characterisation of two distinct wastewaters are reported. ...
