As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been dedicated to providing advanced wastewater treatment solutions since 2015. Our Textile Industry High-salinity Wastewater Treatment Equipment for Dyeing Effluent Treatment is designed to tackle the most challenging effluents generated by textile dyeing processes. With a factory spanning 10,000-30,000 square meters and a team of 201-300 skilled professionals, we combine engineering excellence with rigorous quality control to deliver reliable, high-performance systems. This equipment meets the strict demands of textile mills worldwide, helping them achieve discharge standards and water reuse goals while minimizing environmental impact.
Our treatment system is specifically engineered for high-salinity dyeing wastewater, which often contains high concentrations of salts, dyes, and organic pollutants. By integrating advanced evaporation, membrane filtration, and crystallization technologies, the equipment effectively separates clean water from concentrated brine, enabling up to 95% water recovery and zero liquid discharge (ZLD) capability. The system is fully customizable to handle varying flow rates from 50 to 5000 m³/day, making it suitable for both small workshops and large textile plants.
Key Features & Technical Specifications:
- High-Efficiency Evaporation: Utilizes Mechanical Vapor Recompression (MVR) technology to reduce energy consumption by up to 60% compared to traditional evaporators.
- Robust Membrane Filtration: Includes reverse osmosis (RO) and nanofiltration (NF) modules to remove dissolved salts and color compounds.
- Automated Operation: PLC-based control system with HMI touchscreen allows for real-time monitoring and remote control, reducing labor costs.
- Anti-Corrosion Design: All wetted parts are made of 304 stainless steel or high-grade corrosion-resistant materials, ensuring long service life in saline environments.
- Compact Footprint: Skid-mounted design saves floor space and simplifies installation.
- Compliance with Standards: Designed to meet local discharge regulations and international environmental standards.

Frequently Asked Questions (FAQ):
1. What is the maximum salinity level your equipment can handle?
Our system can treat feed water with TDS up to 100,000 mg/L. For higher salinity, we can incorporate additional pre-treatment stages.
2. How much water can be recovered from the wastewater?
Typically, recovery rates range from 90% to 95%, depending on the specific composition of your effluent. We can customize the design to achieve your target.
3. What is the energy consumption of this equipment?
Energy consumption varies from 40 to 80 kWh per cubic meter of treated water, depending on salinity and operating conditions. Our MVR technology significantly reduces energy use compared to conventional methods.
4. Can the equipment handle fluctuating flow rates?
Yes, the system is designed with buffer tanks and flexible control logic to accommodate variations in influent flow. We can also integrate flow equalization for stable operation.
5. What are the maintenance requirements?
Routine maintenance includes periodic cleaning of membranes, inspection of pumps and valves, and replacement of consumables like filters. The PLC system provides alerts for preventive maintenance.
6. Do you provide installation and training services?
Absolutely. We offer comprehensive on-site installation, commissioning, and training for your operators. Remote support is also available via our technical team.
7. How long does the equipment last?
With proper maintenance, the equipment has a service life of 15–20 years. The use of corrosion-resistant materials ensures durability in harsh saline environments.
8. Can you customize the system for specific salts or dyes?
Yes, we customize the process flow based on the chemical analysis of your wastewater. Our engineers will design the optimal combination of evaporation, membrane, and crystallization units for your specific application.
