Wastewater Treatment & Reclaim · Gas Recovery
Treat every drop of water and every unit of gas as a resource — segregated wastewater treatment, water reuse and PFC reduction and recovery let environmental regulation and sustainability targets be met together.
SCOPE · Scope
What we take on
S-01
Wastewater segregation
Collection piping for five segregated streams — acid-alkali, fluoride, CMP, organic and copper-bearing — with quality and flow balance planning.
S-02
Wastewater treatment works
Design, procurement and construction management of neutralization, coagulation-sedimentation, biological treatment and AOP units.
S-03
Discharge and permitting
Effluent standard compliance assessment, discharge permit applications and continuous monitoring at the outfall.
S-04
Water reclaim system
RO／UF membrane system design, reclaimed water quality grading and supply loops to every process reuse point.
S-05
Sludge handling
Sludge minimization and dewatering system design, plus assessment and management of resource-recovery disposal routes.
S-06
Exhaust abatement
Local scrubber selection and layout for point sources, with airflow and tower sizing for the central scrubber system.
S-07
PFC reduction
Abatement engineering for SF₆, NF₃ and other greenhouse gases, with emission factor inventories and verification of reduction performance.
S-08
Specialty gas recovery
Gas purification and reuse loop design, with technical and economic feasibility assessment of each recovery option.
RECOVERY · Recovery
Recovery is not a cost. It is capacity insurance.
Dry-season supply risk and tightening ESG disclosure have turned the recovery rate from an environmental figure into a resilience metric — every percentage point gained is one point less exposure to a water outage. TeraFab starts from the water balance and exhaust inventory, assessing the technical feasibility and payback period of each recovery option so every dollar invested is aimed at risk.

METHOD · Approach
How a turnkey consultancy works
01
Water and gas inventory
Survey process wastewater quality and volume and exhaust composition, build the water balance diagram and emission baseline, and set recovery targets.
02
Design integration
Process design of segregation piping, treatment units and reuse loops, coordinated in BIM with B1 services and the offsite facility layout.
03
Procurement and construction management
Specifications, vendor selection and full-term supervision for treatment equipment, membrane systems, scrubber towers and other subcontracts.
04
Commissioning and handover
Functional commissioning and effluent quality verification, discharge permit award and handover of operation and maintenance documents.

INTERFACE · Related systems
Recovery systems are not islands
Water balance, monitoring and reporting, and site allocation cut across MEP, facility systems and civil works — these interfaces are exactly where a turnkey consultancy adds value.
