Green Energy for Greener Tommorrow

Biogas is the ideal energy solution for today's world. It provides clean fuel to to meet demands, reduces load on the local power grid and also produces organic manure for farming as a by-product.

Since biogas production utilizes bio waste, pasteurized biomass, condensed substrate, digestate feed and slaughter house waste; it also significantaly reduces water and land waste.

Biogas Production

  • Bio-Mix pump is used to mix and transfer slurry made of macerated bio-waste and digestate liquid into fermentation
  • In an oxygen free environment inside fermentation tanks; micro organism transform organic matter into methane rich biogas and carbon-dioxide through a process called anaaerobic digestion
  • A progressive cavity pump is used to circulate the sludge heat exchangers to maintane sludge temperature. This ensures that anaerobic bacteria remains intact inside fermentation tank.
  • After fermentation, the resulting digestate slurry is transferred by biomasspump to open lagoons/storage tanks.
  • Finally, progressive cavity pump is used for filling the organic manure into tankers

Progressive Cavity Pump Applications in Biogas Industry

  • Feeding highly viscous bio-waste slurry to fermentation tanks.
  • Recirculation of fermentation tank slurry and feeding to digestate storage tanks
  • Mixing of Bio-waste with the digestate slurry
  • Transfer of digestate to bio-mix unit & open lagoon/storage tank
  • Transferring Organic Manure from open lagoon/storage tanks to tankers
