Center Enamel Industrial Wastewater Treatment Project and GFS Tanks Engineering
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. To successfully navigate these stringent regulatory frameworks within any Industrial Wastewater Treatment Project, Center Enamel provides compliant engineering solutions.
GFS Tanks Adaptable to Complex Operating Conditions
Center Enamel has independently developed over 200 specialized enamel frit formulations and supporting patents, capable of customizing anti-corrosion enamel based on customer storage media, with adaptability comprehensively superior to concrete tanks. Concrete tanks use a single material, only suitable for neutral clean water storage. When storing corrosive materials such as livestock manure, palm oil mill effluent, chemical wastewater, food waste digestate, high-salinity wastewater, etc., additional anti-corrosion linings must be applied. These linings are prone to failure, preventing long-term stable operation and cannot adapt to alternating high/low concentration storage conditions.
GFS Tanks can be specifically formulated with specialized enamels resistant to strong acids, strong alkalis, high organic content, and high salinity. A single tank can switch between multiple wastewater and fermentation feedstock storage requirements. They are universally applicable across biogas anaerobic digestion, municipal wastewater, livestock farming, food processing, and industrial water treatment scenarios, eliminating the need to rebuild tanks for media changes, perfectly meeting the needs of diversified, multi-condition environmental protection projects deployed in every Industrial Wastewater Treatment Project.
CSTR Core Advantages
Excellent adaptability, with outstanding treatment results for high-solids, high-viscosity, high-suspended-solids organic wastewater, thoroughly solving the shortcomings of traditional anaerobic processes such as stratification, crusting, and low sludge utilization. The full-mix agitation mode ensures thorough contact between microorganisms and pollutants, with homogeneous and stable reaction conditions and excellent resistance to water quality and hydraulic shock loads-stable compliance even with significant influent fluctuations.
The simple process structure, without complex media or three-phase separators, results in low equipment cost, short construction period, and low maintenance difficulty, with no need for frequent cleaning of clogged components and low O&M costs. The process simultaneously achieves wastewater treatment and biogas energy recovery. Sludge acclimation is fast, quickly adapting to various specialty organic wastewaters, with high process error tolerance and strong universal applicability, serving as a core technical choice for Center Enamel.
POME Environmental Toxicity
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.
Malaysia Palm Oil Biogas Project
The project uses Center Enamel GFS Tanks as the core anaerobic digestion facility with 5 tanks, each with effective volume of 5,400 m³, total effective volume 27,000 m³. Influent COD ≥ 60,000 mg/L, BOD ≤ 25,000 mg/L. After anaerobic digestion, effluent COD drops to below 12,000 mg/L, BOD ≤ 5,000 mg/L-overall organic removal efficiency approximately 80%. Single tank daily biogas production 4,400 m³, total project daily biogas 22,000 m³-stable biogas yield of 0.45 m³ per kg COD removed-efficient biogas energy recovery while solving palm oil processing wastewater pollution. This landmark facility highlights the operational capability of Center Enamel in any large-scale Industrial Wastewater Treatment Project.

Full-Process Standardized Installation Quality Control
Demonstrating high-standard installation quality through long-term stable global project performance, Center Enamel has established full-chain quality control standards across four dimensions: factory protection, on-site assembly construction, completion inspection, and long-term warranty-ensuring quality control for every GFS Tanks unit deployed in an Industrial Wastewater Treatment Project.
At the factory stage, all enameled panels, seals, and structural components receive rust-proof and moisture-proof independent packaging with dedicated protective supports-preventing damage during sea and land transport and avoiding enamel coating damage.
On-site construction strictly follows unified assembly process specifications-panel by panel tightening and leak testing in layers, with air-tightness and verticality testing after each tank section completion-dual-membrane covers and anaerobic piping undergo simultaneous pressure testing and acceptance.
Differentiated quality acceptance standards are customized for different regions: EU/US projects follow stringent CE/NSF inspection criteria; Southeast Asian hot humid regions receive enhanced corrosion protection and sealing acceptance; remote African sites have additional foundation settlement re-inspection procedures. Upon project completion, complete construction inspection reports, pressure test records, and anti-corrosion appearance acceptance documents are issued, with full photo/video archives retained. Over 10,000 tanks delivered globally have operated long-term without large-scale leakage or structural deformation-preventing future O&M issues at source.
