Reliable EPC Contractor Using USR Process for POME Treatment Projects
The competitive landscape shows divergence, with leading companies building integrated service capabilities through technical integration and capital operations, and industry concentration gradually increasing. Chinese companies continue to consolidate their advantages in mid-tier equipment exports. International giants target high-end customers and complex industrial wastewater markets, while local players occupy the mid- to low-end and industrial park centralized treatment markets with service responsiveness and cost advantages.
In the anaerobic process segment, UASB, EGSB, and IC anaerobic reactors, with advantages of high loading rates, small footprints, and stable operation, are widely used in high-concentration organic wastewater pretreatment in food processing, pharmaceutical fermentation, alcohol brewing, chemical, and other industries. These reactors use steel tank shells, and their corrosion resistance and gas-tightness directly determine long-term operational stability. The application value of glass-fused-to-steel tanks in such scenarios is increasingly prominent.
As an experienced EPC Contractor, Center Enamel combines this equipment advantage with complete engineering delivery. The USR Process, in particular, offers a robust solution for high-solids wastewater streams where conventional reactors struggle.
USR Supporting Equipment
Core equipment is the GFS tank with no complex media or precision three-phase separators, featuring a rugged clog-resistant structure. Bottom large-diameter anti-clogging distribution system suitable for high-solids wastewater, preventing pipe clogging. Supporting equipment includes influent lift pumps, simple pretreatment screens, and equalization tanks for impurity removal and water quality balancing. Simple top gas collection devices and biogas conveying/desulfurization equipment for biogas resource recovery. Temperature, level, and pH online monitoring equipment. Bottom large-diameter sludge discharge pipes and pumps for rapid removal of high-concentration residual sludge, suitable for high-solids conditions. The complete system has extremely low failure rates, outstanding wear and clog resistance, and is far easier to maintain than conventional anaerobic processes.
This simplified, clog-resistant equipment configuration is what makes the USR Process so dependable in demanding agro-industrial applications. Among these, POME Treatment Projects represent one of the most challenging and rewarding use cases.
Palm Oil Mill Effluent Standardized Treatment Solutions
Core treatment uses a mature train of "oil separation/cooling pretreatment + CSTR/USR anaerobic digestion + aerobic treatment + advanced treatment"-perfectly suited for POME's high-concentration, high-oil, high-temperature, low-pH characteristics. Pretreatment: Raw POME first enters oil separation tanks/oil separators to remove free and dispersed oil-recovered palm oil can be sold as a resource, significantly reducing organic load. Cooling towers/heat exchangers reduce temperature from 60-80°C to 35-38°C for mesophilic anaerobic digestion. Lime/NaOH addition adjusts pH from 4.0-5.0 to 6.8-7.2 for optimal anaerobic conditions. Screens and sedimentation tanks remove fruit shell fibers, fruit pulp residues, and other large suspended solids to prevent distribution system and pipe clogging.
Main anaerobic treatment: Center Enamel CSTR or USR anaerobic reactors with GFS tanks as core reaction equipment, suited to POME's high-concentration, high-oil, high-suspended-solids conditions. CSTR mechanical mixing addresses oil floating layers, suspended solids sedimentation, and surface crusting-the three major challenges-ensuring thorough material-microbe contact. USR simplifies internal structure with anti-clogging, high-solids tolerance-suited for high-suspended-solids POME. Single GFS anaerobic tank effective volume 3,000-10,000 m³, with multiple tanks configurable for different mill capacities. Anaerobic digestion HRT 20-30 days, COD removal 80-90%, BOD removal 85-92%, with simultaneous large-volume biogas production. Aerobic treatment: Anaerobic effluent still has COD 3,000-10,000 mg/L-requiring aerobic polishing.
A/O, A²O, or SBR processes further degrade residual organics and remove nitrogen/phosphorus, reducing COD to 200-500 mg/L and BOD to 50-100 mg/L. Advanced treatment: Depending on discharge standards or reuse requirements, BAF, coagulation/sedimentation, sand filtration, or constructed wetlands reduce COD to below 100 mg/L and ammonia to below 10 mg/L for irrigation reuse or surface discharge compliance. Biogas utilization: POME anaerobic digestion produces exceptionally high biogas yields-8-15 m³ biogas per m³ wastewater-after desulfurization and dehydration, biogas can be used for CHP, meeting 30-50% of mill electricity demand, with waste heat used for digester heating and FFB sterilization preheating-achieving energy self-sufficiency.
Delivering this complete treatment train requires both process expertise and a broad equipment portfolio. As a full-service EPC Contractor, Center Enamel provides exactly this combination through its comprehensive product matrix.
