3 Technologies for Economic Development Introduction: In nature all nutrients, which are consumed by animals and microorganisms must be taken back to the soil to establish new life. However, human excreta and urine are often taken out of this reproductive cycle. They are stored in septic tanks where they contaminate the underground water, disposed off into the rivers, lakes and sea, pumped or transported to sewage treatment facilities. TED Water quality is therefore deteriorating due to pollution resulting from the above and from population growth particularly in urban areas hence ecological sanitation technologies have to be implemented.

4 Technologies for Economic Development Biogas technology : TED A modern, ecology - oriented form of appropriate technology based on the decomposition of organic materials by putrefactive bacteria at suitable, stable temperatures. A combustible mixture of methane and carbon dioxide, commonly referred to as biogas, develops under air exclusion (leaving behind digested slurry) in the digester - the heart of - any biogas plant.

5 Technologies for Economic Development Why Biogas Technology? Biodigesters Biodigesters Biodigesters Biodigesters sanitize wastewater on your compound and make it fit for irrigation. turn organic matter into cooking gas save your cost and headache on sewage transport encourage home gardening TED

6 Technologies for Economic Development Biogas Systems for individual households and communities technological package o Bio-digester o Expansion chamber o Root treatment TED treating wastewater on premises with gardens biologically (anaerobically and aerobically) appropriate particularly as many households and institutions have serious problems and cost with the disposal of their sewage.

7 Components together Feeding material. Gas taken to the house Irrigation by gravity Methane producing organisms produce gas Root Treatment System Storage for irrigation water H 2 0 could be pumped or irrigate gravitationally Water flowing into the expansion canal Sketch of biodigester replacing a septic tank. Wastewater as well as kitchen and garden waste enter the digester and are broken down to biogas and fertile water. The advantages: No more emptying of septic tank. Reuse of all water in the garden. Less cost on cooking energy.

10 Digging

11 How to make a perfect circle 1 Meter up

12 Dome taking shape Adding chicken mesh and plastering all the way bricks sideways

13 Building the dome ask for some builders tricks Expansion canal in the back

14 Next step to place gas outlet pipe Plaster

15 Notice gas outlet on top

16 Still chicken mesh & plaster

17 Backfilling

18 Inlet canal from dairy Gas outlet chamber

19 3. Paint inside of dome on a flame heated surface to get an airtight dome! 1. Take one packet of candles and melt them. 2 Mix with one tin motor oil..

20 Gas pipe Nearly finished

21 sanitize wastewater on your compound and make it fit for irrigation/save drinking water.

22 Turn organic Waste into cooking gas

23 Save your cost and headache on sewage transport

24 Encourage Home Gardening
