  1. 1. Onsite greywater treatment for reuse at Zandspruit informal settlement in Johannesburg

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Tendai H Madzaramba; [2019]
    Nyckelord :Greywater generation; greywater treatment; greywater reuse; wastewater reuse; informal settlements; Technology and Engineering;

    Sammanfattning : The urban landscape in South Africa is marred by informal settlements. Nearly a quarter of its population lives in shacks and do not have access to sufficient clean water and improved sanitation. The aim of the present study was to ascertain household daily water consumption and quantify the amount of greywater generated at Zandspruit slums. LÄS MER
