Qingdao Conqinphi Environmental Technology Group Co., Ltd. presents an advanced Zero-Discharge High-Salt Wastewater Treatment System featuring a dedicated Crystallization Evaporator, designed specifically for chemical plants seeking sustainable and regulatory-compliant liquid waste management. As a leading manufacturer established in 2015 with a 10,000-30,000 square meter factory and annual export value exceeding US$10 million, we integrate cutting-edge evaporation and crystallization technology to achieve true zero liquid discharge (ZLD), recovering up to 98% of water as high-purity distillate and isolating solid salts for potential reuse. This system not only eliminates environmental liability but also transforms waste into a resource, aligning with global circular economy initiatives.
Key Features & Technical Specifications
- Zero Discharge Capability: Our crystallization evaporator efficiently separates high-salinity wastewater into clean distilled water (TDS
- Energy-Efficient Operation: Utilizes Mechanical Vapor Recompression (MVR) technology, reducing energy consumption by up to 60% compared to traditional evaporation methods.
- Robust Material Construction: Fully customizable in 304 or 316L stainless steel, with optional titanium alloy for highly corrosive brines, ensuring long service life in aggressive chemical environments.
- Modular & Compact Design: Pre-engineered skid-mounted units simplify installation and allow easy capacity expansion from 10 to 200 m³ per day per module.
- Automated Control System: PLC-based with remote monitoring and real-time data logging, enabling unattended operation and consistent performance.
- Multi-Effect Configuration: Available in single-effect or multi-effect (up to 4 effects) to optimize heat recovery and minimize operating costs for different salt concentrations.
Typical Technical Parameters (Example Unit)
| Parameter | Specification |
|---|---|
| Feed TDS Range | 30,000 – 250,000 mg/L |
| Evaporation Capacity | 10 – 200 m³/day per unit |
| Operating Temperature | 60 – 100 °C (adjustable) |
| Distillate Quality | TDS |
| Solid Salt Purity | > 95% dry basis (customizable) |
| Power Consumption | 40 – 80 kWh per ton of evaporated water (MVR mode) |
Advantages for Chemical Plants
- Regulatory Compliance: Meets stringent discharge standards worldwide, including China’s GB and international environmental regulations, by eliminating wastewater discharge entirely.
- Cost Savings: Reduces fresh water procurement and waste disposal costs; recovered distillate can be reused in cooling, washing, or as boiler feedwater.
- Resource Recovery: Extracted crystalline salts (e.g., NaCl, Na₂SO₄) can be sold or reused as industrial raw materials, creating a revenue stream.
- Low Maintenance: Anti-scaling and anti-fouling designed internals, combined with automatic cleaning-in-place (CIP) cycles, minimize downtime.
- Flexibility: Suitable for wastewater from chemical synthesis, dye production, pesticide manufacturing, and other high-salt streams with varying compositions.

Frequently Asked Questions (FAQ)
- What is the minimum TDS required for this crystallization evaporator? The system can handle feed TDS from approximately 30,000 mg/L up to saturation. For lower TDS streams, we recommend upstream concentration (e.g., RO or NF) to optimize efficiency.
- How durable is the equipment for corrosive brines? We offer materials such as 316L SS, duplex stainless steel, or titanium depending on chloride and pH levels. All wetted parts are resistant to the specific chemical environment of your plant.
- Can the system handle varying flow rates and compositions? Yes, the PLC-controlled design allows automatic adjustment within a range of ±20% of design flow. For extreme variations, a buffer tank and pre-treatment module are included.
- What is the typical return on investment (ROI)? ROI depends on water cost, disposal fees, and salt value. Many clients achieve payback within 2-4 years through water recovery and waste reduction.
- Do you provide turnkey installation? Yes, we offer complete turnkey solutions including site assessment, civil works (if needed), system integration, and commissioning. Our team can also train your operators.
- What certifications do your products carry? Our factory is certified under ISO9001, ISO14001, OHSAS18001, and we can provide specific documentation to satisfy local regulatory requirements upon request.
- How is the solid salt disposed or reused? The crystalline salt can be collected as a dry powder or granules. It may be landfilled as non-hazardous waste (if inert) or sold to chemical companies. We can assist in evaluating salt purity for reuse.
- What after-sales support is offered? We provide a 12-month warranty, spare parts availability, remote technical support, and optional annual maintenance contracts. Our global service network ensures rapid response.
