  2. 1. Phosphorus recycling from wastewater to agriculture using reactive filter media

    Author : Victor Cucarella Cabañas; Gunno Renman; Dan Berggren Kleja; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Filtra P; phosphorus; Polonite; recycling; sorption; wollastonite; Water in nature and society; Vatten i natur och samhälle;

    Abstract : This thesis focused on testing the suitability of reactive filter media used for phosphorus (P) removal from wastewater as fertilizers, thus recycling P to agriculture. The work compared the P sorption capacity of several materials in order to assess their suitability as a source of P for plants. READ MORE

    Abstract : Phosphorus is an essential component in all living organisms; it is one of the components of the DNA and the key element in the energy supplying molecule adenosine triphosphate (ATP). Throughout the history, humans have been recycling phosphorus to agriculture; thereby increasing the yield, examples of this includes the burning of plants and the use of manure. READ MORE

    Abstract : Concerns about potential risks posed by discharge from small-scale wastewater treatment (SWT) systems to receiving water bodies have prompted robust enforcement of national discharge quality standards in rural areas of most developed countries. Consequently, communities in such places are in need of effective technologies with which to achieve compliance. READ MORE
