iii. Wait for 4 hours and then measure the pH level again - if it is still below
6.5, repeat the previous step and add more sodium bicarbonate.
2. If pH level is above 6.5, let gas accumulate and try to light it. If gas is
flammable, resume feeding and using the system.
3. If gas is not flammable: empty the gas tank, allow gas to accumulate
for a day and try to light again.
(Note: Adding sodium bicarbonate makes the system generate carbon
dioxide (CO2) which may make the initial gas collect
ed non-flammable).
i. Do this for 5 days till you have flammable gas.
ii. If 5 days have passed and you still do not have flammable gas, the system
may not have enough organic material to produce gas. Add 40 liters of
fresh animal manure and try to light the gas after a week.
If the system still produces non-flammable gas after carrying out the
previous steps, please contact us at support@homebiogas.com.
Try to allow the system’s pH to stabilize itself.
i. Empty the gas tank through the Drainage Connector. Close the connector
once the tank is empty.
ii. Stop feeding the system for a week. On the 3rd day, try to light a flame. If
the gas does not burn, empty the gas tank again and close the Drainage
Connector.
iii. After a week, try to light a flame again. If the flame still does not burn
you may need to increase the system’s pH.
1. Measure the system’s pH level with a measuring kit (bought
separately) and add fresh manure to the system.
i. First drain at least 2 liters of water from the fertilizer outlet, to get a “fresh”
sample of liquid from the digester tank. Then, take a sample of liquid
from the fertilizer outlet.
ii. Follow the instructions that come with your pH measuring kit to test pH
level of the sample. (Reduce 0.2 from the pH test reading if you have a
chlorine tablet installed.
If the system’s pH is lower than 6.5, add fresh manure to the system and
mix well with plunger, according to the pH level measured:
(prepare suitable containers/piping to drain away the digester liquid
which will flow out when adding the manure.)
The system may be producing more CO2 than methane due to low pH
values in the digester.
Tank is filled, gas flows out but does not burn, or
flame dies after a few seconds
