Jan Spit from WASTE presented the research findings on faecal sludge treatment during the Faecal Sludge Management Lunch Meeting in The Hague, The Netherlands, on 17 April 2014. This meeting was organised by IRC with support from DGIS.


  • 1.Research Faecal Sludge Treatment

2. Background Gap Analysis in Emergency Water, Sanitation and Hygiene Promotion (HIF 2013) 1. Latrines in locations where no pits are possible (urban, high watertable/flooding) 2. Latrine emptying and desludging 3. Faecal sludge disposal options after desludging and treatment !!MOST CHALLENGING GAP!! 4. Urban alternatives for excreta disposal 3. Problem Lack of space for treatment (urban area) High water table (no digging possible) No off site treatment/disposal site, no skilled labour Security Faecal sludge source of disease (Cholera Haiti) Raised latrine full after 1 week 4. Objective Sanitization Faecal Sludge Simple & rapid & easy to put in place Easy to operate & maintain & reliable Demonstrate feasibility at scale and document the whole process Process to be incorporated in the Oxfam and/or IFRC catalogue From Speed to Seed 5. Field testing Malawi 5 Students from Unesco- IHE & TUD 3 Treatment Methods for Centralised Treatment : Lime, Ammonia, Lactic Acid 3 Decentralised Treatment (SEED)- on- going research: Worm Toilet, Terra Preta Toilet, Anaerobic Digester 6. Emergency Faecal Sludge Treatment Methods: Preliminary Field Testing Results Treatment Treatment Time Final Concentration of E-coli, Salmonella and Faecal Coliform pH Quantities of Chemical Addition for Treatment Ammonia 4-8 days
