  4. 2. Coagulant Protein from plant materials: Potential Water Treatment Agent

    Author : Ida Bodlund; Gunaratna Kuttuva Rajarao; Anna Norström; Andres Veide; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antimicrobial effect; Brassica; coagulant protein; MO2.1; Moringa oleifera; Mustard; napin; thermo-resistance; plant material; protein extraction; salt extract.;

    Abstract : Access to fresh water is a human right, yet more than 780 million people, especially in rural areas, rely on unimproved sources and the need for finding ways of treating water is crucial. Although the use of natural coagulant protein in drinking water treatment has been discussed for a long time, the method is still not in practice, probably due to availability of material and limited knowledge.

  5. 3. Moringa seed and pumice as alternative natural materials for drinking water treatment

    Author : Kebreab Afwerki Ghebremichael; Bengt Hultman; Hallvard Ödegaard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; antimicrobial effects; coagulant protein; dual media filtration; ion exchange; Moringa oleifera; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : Pumice and the Moringa oleifera (MO) seed were investigated as alternative natural materials for drinking water treatment based on problems identified at the Stretta Vaudetto water treatment plant in Eritrea. Lab and pilot scale studies showed that pumice was a suitable alternative material for dual media filtration. READ MORE

  7. 5. Water Supply in Tanzania and Performance of Local Plant Materials in Purification of Turbid Water

    Author : Nancy Marobhe; Gunno Renman; Gunnar Jacks; Msafiri Jackson; Tapio Katko; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antibacterial effect; Coagulant proteins; Vigna unguiculata; Parkinsonia aculeata; Ion exchange; Tanzania water supply; Water engineering; Vattenteknik;

    Abstract : Water supply services in urban and rural areas of Tanzania were reviewed and specific studies were carried out on water supply and on purification of turbid water sources using locally available plant materials in rural villages of Singida Rural District. The review showed that large proportions of urban and rural populations in Tanzania face acute water supply problems mainly due to poor planning, implementation and management of water supply projects, including an inability to address social, technical, operation and maintenance and financial issues.
