Leading USR Process with Reliable EPC Solutions for POME Treatment Project

Global industrial wastewater treatment policies are escalating from "compliance discharge" to mandatory "resource recovery" and "zero liquid discharge." The EU, through its Circular Economy Action Plan, requires member states to increase industrial wastewater reuse rates and extends carbon footprint accounting to the full life cycle of wastewater treatment. China continuously updates and tightens industrial water pollutant discharge standards, with increasingly stringent limits on total nitrogen, total phosphorus, and characteristic pollutants for industries such as chemicals, pharmaceuticals, and printing and dyeing. Some water-scarce regions and highly polluting industries are mandated to adopt zero or near-zero liquid discharge technologies. Germany has established a differentiated pretreatment technical standard system by industry, requiring industrial wastewater to meet specific quality requirements before discharge into municipal wastewater treatment plants, implementing strict source control.

These tightening regulations place new pressure on project owners to select treatment technologies that are both compliant and economically sustainable. Meeting this dual requirement demands more than equipment supply-it calls for integrated EPC Solutions that combine process design, durable containment, and long-term operational support. The USR Process has emerged as a direct answer to these demands, particularly for the high-solids streams common in agricultural and palm oil processing.

USR Process Advantages: Simplicity, Durability, and Operational Resilience

High solids tolerance, clog resistance, and strong adaptability, perfectly suited for high-suspended-solids, high-impurity, high-solids organic wastewater. Extremely simple equipment structure, no precision wear parts, low capital investment, long service life, virtually no clogging failures, and extremely low subsequent maintenance costs. No strict requirements on sludge morphology-no need to cultivate mature granular sludge, flocculent sludge can operate stably, with fast start-up and short sludge acclimation period for rapid commissioning. Gentle hydraulic disturbance results in low sludge washout and high sludge utilization, with stable organic pollutant degradation. Simple operation with low automation requirements and high error tolerance, suitable for remote sites, farms, and other settings with limited O&M capabilities-outstanding stability and practicality advantages.

These advantages explain why the USR Process is increasingly specified for projects where conventional high-rate anaerobic reactors would struggle. The same robustness that makes it tolerant of high solids also makes it a natural fit for a POME Treatment Project, where oil, fiber, and colloidal solids would otherwise cause rapid system failure.

POME Environmental Toxicity: Why Proper Treatment Is Non-Negotiable

POME pollutants are primarily natural plant organics with no synthetic toxic chemicals, heavy metals, or persistent organics-low acute chemical toxicity, but high-concentration organic and oil pollution have severe ecological impacts. High-concentration organics discharged to natural waters rapidly deplete dissolved oxygen-BOD load far exceeds self-purification capacity, causing severe oxygen depletion, anaerobic production of hydrogen sulfide and ammonia, black-odor conditions, mass mortality of fish and benthic organisms, and complete ecosystem collapse. High-concentration oil forms surface films blocking atmospheric-water oxygen exchange-exacerbating oxygen depletion; oil adheres to fish gills and aquatic organism surfaces, directly affecting respiration, feeding, and movement; oil degrades slowly, causing persistent ecological damage.

Acidic raw water (pH 4-5) acidifies receiving waters, causing pH drops beyond aquatic organism tolerance-leading to fish kills and aquatic vegetation die-off; acidic conditions promote heavy metal mobilization from sediments, creating secondary pollution risks. High suspended solids settle and cover riverbed sediments, blocking benthic habitats and fish spawning grounds; fruit pulp and fiber decomposition consumes sediment oxygen, causing anaerobic conditions and hydrogen sulfide accumulation. High ammonia nitrogen undergoes nitrification consuming dissolved oxygen-exacerbating eutrophication.

Nitrogen and phosphorus nutrient enrichment triggers algal blooms (water blooms, red tides)-further degrading water quality. In Southeast Asian palm oil producing regions with dense mill concentrations, untreated POME discharge can cause severe water quality degradation over tens of kilometers of rivers, with irreversible aquatic ecosystem damage-POME is a core source of water pollution in tropical regions, with increasingly strict environmental regulations.

Given this level of ecological risk, no palm oil mill can afford a marginal treatment solution. A properly engineered POME Treatment Project must combine high-solids anaerobic technology with corrosion-proof containment and reliable biogas capture. Delivering all three as a single, coordinated package is exactly what Center Enamel's EPC Solutions are designed to accomplish.

Ghana Municipal Domestic Wastewater Treatment Project: Proven Multi-Process Delivery

Completed installation in 2021, treating 1,800 m³/day of municipal wastewater using UBF anaerobic + A²/O nitrogen/phosphorus removal mature processes. Equipped with multiple Center Enamel GFS tanks including 1 UBF anaerobic reactor, 1 secondary clarifier, and 2 internal/external double-layer A²/O biological tanks. Influent has high COD, BOD, suspended solids, and nitrogen/phosphorus concentrations-after full treatment, effluent parameters are significantly reduced with pH stable at 6.5-9.0, fully meeting local environmental discharge standards. Corrosion-resistant, conveniently assembled GFS tanks efficiently solve urban domestic wastewater pollution while balancing treatment effectiveness and O&M economics-a mature municipal wastewater case in Africa.

This project illustrates the breadth of Center Enamel's EPC Solutions-spanning municipal, agricultural, and industrial applications with the same core tank technology. It also demonstrates that the engineering discipline applied to a POME Treatment Project is transferable across wastewater categories and geographies.

Single and Double Membrane Roof Cover Solution: Airtight Gas Collection for Biogas Systems

Single and Double Membrane Roofs are proprietary airtight tank cover systems for anaerobic digestion and biogas storage projects, specifically developed for biogas collection and odor containment, representing a benchmark lightweight sealing solution for fermentation tanks. The single-layer membrane roof features a simple structure with economical cost, meeting basic biogas containment needs. The double-layer membrane roof consists of inner and outer corrosion-resistant membrane materials, with pressurized air in the interlayer forming rigid support, providing outstanding thermal insulation that reduces biogas condensate formation inside the tank, with enhanced wind and snow load resistance suitable for high-altitude and windy outdoor sites.

The membrane material is specialized aging-resistant and biogas-slurry-corrosion-resistant PVDF membrane, which will not leak or degrade from long-term contact with biogas or hydrogen sulfide. The flexible structure accommodates tank settlement and slight deformation without cracking or gas leakage. The lightweight design eliminates heavy steel support trusses, significantly reducing the load on the tank and foundation, saving construction costs. The roof integrates biogas outlets, safety pressure relief valves, and access channels, fully enabling closed gas collection for anaerobic fermentation tanks, recovering biogas for power generation and heating while blocking odor diffusion to meet environmental odor control requirements. It is widely used in large-scale livestock biogas projects, municipal sludge anaerobic digestion, and food waste fermentation projects, compatible with large-volume glass-fused-to-steel anaerobic tanks, with fast construction and simple maintenance requiring only periodic membrane seal integrity checks, offering significant overall engineering advantages.

For a POME Treatment Project generating 8-15 m³ of biogas per m³ of wastewater, reliable gas collection is essential to realizing the economic return that makes these projects viable. The membrane roof completes the USR Process system-ensuring that biogas is safely captured rather than lost, and that odor emissions comply with environmental requirements.
