Sewerage Sludge Technology

THE PROCESS – SUPER CONCENTRATE BIO-SOLIDS

The GGII proprietary process turns 97% liquid wastewater sludge into 20-30% moisture with 70-80% combustible bio-solids. This process achieves the US EPA Part 503 approval – required pathogen vector reduction threshold.

Despite representing only about 1% of total wastewater flows, sludge handling accounts for up to 50% of total treatment plant operation and energy costs.

SLUDGE IS A RESOURCE

Uncovering hidden energy within the hidden sludge (activated sewage sludge usually has a calorific value between 1200 to 1500 kcal/kg, farm sludge will have a higher calorific value ranging between 2000 to 4000 kcal/kg).

INNOVATIVE TREATMENT PROCESS

Single-pass real time separation of liquid-solids without any need for thickening process and polymers dosage.
Separated bio-solids at 70-80% and liquid at 20-30% in one pass.
Combustible bio-solids (with increased GCV)
Flexible in-take points (EQ, O&G trap, Sludge tank)
Resilient to PH, O&G, Temperature, high TS & VS
Modular and tested design
Mobile sludge treatment process
Small footprint

ACHIEVEMENT ON ZERO-DISCHARGE AND ZERO-LANDFILL

Reusable liquid as utility or process water
Bio-solids are used as high GCV alternative solid fuel (with lower GHG emissions).
Alternative usage for bio-solids as soil enhancement fertilizer (only with agriculture sludge).
