- Can the system be used for lighting.?
Yes, it can but it is inefficient to use mantle lamps.
For that, we do recommend that you use the gas to run our BioDC Gen-set, this will charge automotive batteries which in turn will power lights, radio, TV, charge phones etc
- How many cows do I need to maintain the system.?
Dung from 1 cow is enough for the average 6-8 member homestead. BUT you don't actually need to own a cow, all you need is 20 - 30 kgs of waste per day
- Apart from cow dung, what else can I use to feed the digester.?
Dung from pig, sheep, goat, rabbit, chicken droppings or any organic waste, including kitchen waste, water hyacinth, grass and market waste etc
- How frequently do I need to feed the digester?
For continuous production of gas you need to feed the system regularly depending on the gas usage and what you feed in. It is therefor best you to keep to a routine like once a day, or twice a week..
MIXING RATIO 1:1 WASTE: WATER
- If I don't use the gas on a daily basis, what will happen?
Un-used gas will accumulate in the digester. However, if un-used for a long time, the slurry will be ejected from the outlet
- How do I empty the system when it is full..?
The system is of cross-flow design & maintenance free. Fully digested bio-slurry will be automatically ej ected from the outlet.
- How smelly is the waste and what do I do with it?
The bio-slurry ejected has no smell and is NOT a waste. It is in fact a very nutritious organic fertilizer for crops which sterile and has been completely broken down in to minerals ready for absorption by plants
- How durable is the system?
Exposed to the elements, the fabric is manufactured to last over ten years. The micro green-house tunnel further shields
the digester envelope from direct solar UV radiation. The lifespan can be further enhanced by applying a UV sun-screen every 5 -7 years. The tunnel also enhance and maintain high temperatures to increase efficiency of biogas production.
