  1. 1. Product development in low income markets : Identifying user needs and approaches in design in a low income market, with focus on the water filtration market in Malaysia

    Kandidat-uppsats, KTH/Produkt- och tjänstedesign

    Författare :NATALIA LINDGREN; JULIA HEDE MORTENSEN; [2018]
    Nyckelord :;

    Sammanfattning : The water situation in Malaysia is not ideal. Due to the unsatisfactory quality of the piped water, the demand of domestic water filters in Malaysia is increasing. At the same time, 40 percent of the Malaysian population are described as a low income group who are especially vulnerable against increases in living costs. LÄS MER

  3. 2. Automating Residential Water Filters

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Oskar Vågerö; [2018]
    Nyckelord :;

    Sammanfattning : It is not uncommon to install private water filters in Malaysia, to rid the water of heavy metal contaminants, chlorine and bacteria. The main objective of this study was to redesign the base structure of a commercially available water filter (by Blöndal Water Group) in order to allow for an automated backwashing and rinsing function of the filter.

  5. 4. Biokol för rening av kväve och fosfor ur dagvatten i Segeåns avrinningsområde

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Oscar Hassby; [2014]

  7. 5. Pathogen and indicator organisms removal in artificial greywater subjected to aerobic treatment : comparison of four filter media

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Ramiyeh Molaei; [2014]
    Nyckelord :Activated carbon; pine bark; biochar; BOD5 reduction; Enterococcous faecalis; greywater reuse; bacteriophage MS2; bacteriophage фX174; Salmonella spp;

    Sammanfattning : Treated greywater has a good potential to be used as a source of water. This study analyzes the removal of Salmonella spp., Enterococcous faecalis, bacteriophage ɸX174 and bacteriophage MS2 from greywater by filtration through biochar, bark, activated carbon and mixture of bark and activated carbon.
