Anaerobic Treatment for Wastewater from Rubber Plants
FS Entity: Nihon Suido Consultants
Outline of GHG Mitigation ActivityThe advanced digestion system (Biosaver™ TK) will be introduced in a natural rubber factory for its wastewater treatment, and as the pretreatment of the wastewater aerobic process. The current activated sludge process needs an aeration system which consumes large amounts of electricity. The introduction of the advanced digestion system as the wastewater pretreatment will reduce the electricity consumptions for the aeration system.
In addition, the advanced digestion system is capable of recovering methane (CH4) gas efficiently from the low concentration organic wastewater (CODcr concentration is 500 - 5,000 mg/L).
Draft JCM Methodology
Conservatively simplified methodology based on approved small-scale CDM methodology AMS-III.H.
[Parameters to be preconfigured]
-Discharged CODcr load per products etc.
-Discharge volume and light oil consumption
-Electricity generated etc.
Expected GHG Emission Reductions3,325tCO2/yr
← (Light oil reduction in wastewater treatment process
+ Light oil reduction by biogas generation)
x Light oil CO2 emission factor
= (1,054kL+184kL) x 2.68tCO2/kL
