Industrial Evaporator for Wastewater Treatment Plant With High Salt Concentration Processing
Product Spotlights
Qingdao Conqinphi Environmental Technology Group Co., Ltd. is a dedicated manufacturer of advanced wastewater treatment solutions, and our Industrial Evaporator for Wastewater Treatment Plant with High Salt Concentration Processing represents a breakthrough in handling high-salinity effluents. With over 9 years of experience and a factory spanning 10,000–30,000 square meters, we engineer robust, energy-efficient evaporators that convert challenging brine streams into clean water and solid salts. This system is designed for minimal scaling, high recovery rates, and long-term reliability — making it the preferred choice for industries facing stringent zero liquid discharge (ZLD) regulations.
Key Features & Technical Specifications
- High Salt Tolerance: Handles NaCl, Na₂SO₄, CaCl₂, MgCl₂, and mixed brines up to 25% salinity with anti-scaling design.
- Low Energy Consumption: Mechanical Vapor Recompression (MVR) technology reduces operating costs by up to 60% compared to traditional single-effect evaporators.
- Modular & Skid-Mounted: Pre-assembled, compact footprint reduces on-site installation time and cost.
- Corrosion-Resistant Construction: Available in 316L stainless steel, duplex stainless steel, or titanium for aggressive chemical environments.
- Automated Control: PLC + HMI touchscreen with remote monitoring capabilities ensures stable operation 24/7.
- Flexible Output: Can be integrated with crystallizers, centrifuges, or drying systems for complete ZLD.

Advantages for Your Wastewater Treatment
Our evaporator is specifically engineered to tackle high salt concentration streams that are common in chemical, pharmaceutical, textile, petrochemical, and mining industries. By using our system, you gain:
- Zero Liquid Discharge (ZLD) – Eliminates wastewater discharge and meets tight environmental regulations.
- Resource Recovery – Recovered clean water can be reused in your process, reducing freshwater intake.
- Low Maintenance – Anti-fouling design and automatic CIP (clean-in-place) reduce downtime.
- Scalable Design – Units can be paralleled for larger capacities without redesign.

Frequently Asked Questions
-
Q: Can this evaporator handle brine with CaSO₄ scaling?
A: Yes. Our forced circulation design with controlled supersaturation and optional seed crystals minimizes calcium sulfate scaling. We recommend pilot testing for high-fouling streams. -
Q: What is the typical payback period?
A: Typically 1–3 years depending on energy cost, water discharge fees, and recovered water value. Many clients achieve payback in under 2 years. -
Q: Do you provide installation and commissioning support?
A: Yes. We offer on-site supervision, training, and remote technical support for the first year of operation. -
Q: Can the system be integrated with an existing wastewater treatment plant?
A: Absolutely. It is designed as a skid-mounted unit that can be retrofitted into existing pipelines and control systems. -
Q: What is the maximum salt concentration you can process?
A: Our standard design handles up to 25% total dissolved solids (TDS). For higher concentrations, we customize with special materials and throughput adjustments. -
Q: What certifications does the equipment comply with?
A: The manufacturing process follows ISO9001, ISO14000, HACCP, and OHSAS18001 standards. Customized compliance with ASME or CE can be arranged upon request. -
Q: How do you control the final salt purity?
A: Through adjustable evaporation rate, recycle ratio, and optional washing stages. Final salt purity can be >97% for many applications. -
Q: What is the warranty period?
A: Standard warranty is 12 months from commissioning or 18 months from delivery, whichever comes first. Extended warranty available.
