Center Enamel EPC Contractor provides Textile Wastewater Treatment Technology to global customers
The global textile industry is vital to the economy, yet it generates one of the most chemically complex and environmentally challenging waste streams. Textile Wastewater Treatment Technology must contend with highly visible color, extreme variations in temperature and acidity level, high concentrations of total dissolved solids, and a complex cocktail of dyes, sizing agents, and finishing chemicals. The discharge of this effluent must be rigorously managed to meet global sustainability standards, demanding a sophisticated, multi-stage treatment approach and a streamlined project delivery model.
Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) is the specialized EPC Contractor (Engineering, Procurement, and Construction) for the international textile sector. We provide complete, integrated solutions, managing the entire project lifecycle—from detailed process engineering and critical material procurement to guaranteed on-site construction and commissioning. Our single point of responsibility (SPOR) model is essential for navigating the high risks and stringent requirements associated with complex chemical treatment.
Our EPC advantage integrates superior containment—leveraging the chemical resilience of Glass-Fused-to-Steel (GFS) tanks and the specialized durability of Epoxy Coated Steel Tanks—with advanced color removal, biological, and tertiary polishing processes. This ensures every Textile Wastewater Treatment Technology solution is engineered for longevity, reliable color removal, maximum water reuse, and absolute regulatory compliance.
The EPC Contractor Mandate in Textile Wastewater
Textile effluent is characterized by unpredictability, toxicity, and extreme visibility (color). This elevates the need for an EPC Contractor who can deliver a reliable, guaranteed system from a single source.
1. Single Point of Responsibility (SPOR) for Guaranteed Results
Compliance Certainty: As the single EPC Contractor, Center Enamel contractually guarantees that the final treatment system will meet all specific discharge limits, which are often heavily focused on color and residual chemical oxygen demand. This commitment minimizes client regulatory exposure and risk.
Risk and Budget Control: We provide a comprehensive, fixed-price contract and a precise construction timeline, allowing textile manufacturers to accurately budget capital expenditure and minimize delays, which can severely impact production and market readiness.
Integrated System Design: Our engineers specialize in Textile Wastewater Treatment Technology, ensuring critical, high-risk stages—such as chemical mixing, equalization, and biological detoxification—are perfectly integrated and housed in containment structures specifically chosen for chemical resistance.
2. Navigating the Complexity of Textile Effluent
Effective Textile Wastewater Treatment Technology must directly address the effluent's defining, aggressive characteristics:
Intense Color: Dyes are visually potent and often resistant to conventional biological treatment. Specialized chemical and physical-chemical processes are necessary for effective color removal, which forms a core component of our EPC design.
Acidity Level and Temperature Fluctuation: The frequent use of strong acids and alkalis (bases) in dyeing and finishing processes leads to highly variable effluent acidity levels and high temperatures, demanding containment materials with exceptional tolerance for both chemical and thermal shock.
Refractory Organics and Salts: Many finishing chemicals and dye components are difficult to break down biologically, requiring advanced treatment methods to meet final discharge requirements.
Tailored Containment: Optimal Material Selection by the EPC Contractor
The aggressive and corrosive nature of textile waste requires strategic material selection to ensure asset longevity. Center Enamel’s EPC delivery specifies the optimal containment material for each distinct stage of the multi-barrier process.
1. Glass-Fused-to-Steel (GFS) for Critical and Corrosive Vessels
GFS tanks are the essential foundation for processes involving extreme chemical stress, high temperature, and toxic streams:
Chemical Equalization and Neutralization: GFS provides the highest chemical resistance to the extreme acidity level fluctuations and corrosive chemical reagents used to balance the effluent, ensuring the longevity of the vessel, which would rapidly corrode standard steel or concrete.
Biological Reactors (Aeration Basins): GFS containment supports the high-intensity aeration and mixing required for biological treatment. The inert, smooth surface resists chemical attack from residual dyes and finishing agents, promoting stable biological performance.
Sludge Holding: GFS is ideal for holding concentrated chemical sludge, which often contains heavy metals and concentrated, corrosive agents from the dyeing and finishing processes.
2. Epoxy Coated Steel Tanks for Supportive Infrastructure
For non-critical storage, utility water, or areas with lower chemical risk, Epoxy Coated Steel Tanks are specified for their cost-effectiveness and rapid deployment:
Treated Effluent Storage: These tanks are used for storing treated or recycled water, providing a durable, quick-to-install option that complements the high-performance GFS reactors.
Pre-Treatment Buffer Tanks: Where the initial effluent is managed for large-scale flow balancing before primary chemical treatment, epoxy tanks offer a strong, budget-conscious structural solution.
3. Aluminum Dome Roofs for Quality Protection and Emission Control
Center Enamel integrates Aluminum Dome Roofs into our EPC design for specific containment units to protect water purity and control emissions.
Recycled Water Integrity: For storage tanks holding treated, reclaimed water (used for dyeing or general washdown), the aluminum roof provides a crucial, permanent barrier against external airborne contamination and dust, preserving the high quality needed for reuse in sensitive processes.
Vapor and Odor Control: The lightweight, self-supporting dome structure can be deployed over pre-treatment and equalization basins to effectively contain volatile organic compounds and chemical odors, ensuring compliance with local air quality regulations.
Core Textile Wastewater Treatment Technology and Resource Recovery
As an EPC Contractor, Center Enamel focuses on integrating multi-stage processes to first break down the complex chemical structures and then remove the bulk organic load, driving toward compliance and resource reclamation.
1. Physical-Chemical Color Removal
Effective color removal is the first barrier to compliance:
Coagulation and Flocculation: Specialized chemical dosing systems (often housed in GFS vessels) are used to break down dye molecules and aggregate colloidal solids for primary sedimentation.
Advanced Oxidation Processes (AOPs): Where refractory dyes are present, AOPs are integrated as part of the EPC scope to chemically destroy complex organic structures that resist biological breakdown.
2. Biological Treatment for Organic Load Reduction
Following color and chemical pre-treatment, the organic load is managed:
Aerobic Systems: Activated sludge or Sequencing Batch Reactors (SBR), housed in GFS basins, are used to effectively remove the remaining biodegradable organic material.
Sludge Management: The high volume of sludge generated from chemical and biological processes is thickened and dewatered, often using a Double Membrane Roof over the sludge holding tanks where anaerobic digestion is utilized to reduce volume and capture biogas. The sealed roof provides a secure, gas-tight volume to store the recovered gas.
3. Water Reclamation and Reuse
Given the textile industry's high water footprint, advanced reclamation is a key goal of our Textile Wastewater Treatment Technology:
Tertiary Filtration: Pressure filtration and membrane filtration systems (Ultrafiltration or Reverse Osmosis) are integrated as part of the EPC delivery to polish the effluent to a quality suitable for reuse in non-critical processes or even in certain dyeing stages, significantly lowering reliance on freshwater sources.
