Maintenance of your bio gas unit

There is no much maintenance required on your bio gas unit. The only thing owners must do, depending on the size of the system, feed properly, mix the digester and remove the slurry regularly. Annually change the iron wool inside the H2S filter.

  1. An average day/ night environmental temperature should be 270C-300C.
  2. Never exceed the maximum daily input of organic matter.
  3. Keeping the system’s pH in the optimal range.
  4. The system must be feed water with food every day as per the recommended quantity. 
  5. Remove the liquid Fertilizer daily.

What can you feed

Any perishable food/waste thrown away from your home/restaurant/hospital or any other institution can be used for this purpose.

Materials you can be used as feed to the new biogas unit

  • Vegetable waste thrown away from the kitchen,
  • rice, grains, dhal washing water
  • Fruit waste
  • Animal excreta
  • Discarded sucrose i.e. fruits rich in sugar
  • Meat and fish, which contain a lot of protein
  • waste Cereals
  • coconut water
  • Leaves of the plant called Glydiceria/Albizia/Adappa/Vatamara (Do not use these daily. Once a week lightly dry and powder if possible.)
  • Aquatic plants like Azolla, Salvinia, Japanese jabara etc
  • By reducing the size of the pieces of material you add (i.e. adding as small pieces as possible), digestion becomes easier.

If the gas is not flammable

Flame test on bio gas

  • Stop the feeding to your unit.
  • Check the ph level and inform to the company if it has been deviated from suitable ph level.
  • Then release the inflammable gas from the collector. It is important to stay away from the place while the gas is being removed.
  • When the collector is empty, close the taps and collect gas again.
  • Check the gas collected daily for the flame and wait again for a few more days for the gas to form and ignite the flame.
  • When gas become flammable, you can start feeding again.
  • If your system is not flammable for 1 week, contact the company for further instruction.

Smell of Bio Gas unit

There are no smells produced to the environment by your segregated bio gas unit. In combined bio gas unit there can be a smell which can be spread maximum up to 1m. It can be removed by some treatments. As hazardous gases like H2S smells are treated by filters. 

Cleaning the unit

Your bio gas unit doesn’t need to be cleaned of sludge since it has built in such a manner that very little sludge is produced, which has minimal impact on gas production and doesn’t need to be cleaned or given any extra care. Under anaerobic digestion each component of the disposable wastage which you enter in to the digester is digested by the bacteria and eliminate from the digester as liquid fertilizer.
