Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – a leading manufacturer of advanced environmental solutions since 2015. Our Forced Evaporation Crystallizer for Zero Liquid Discharge is specifically engineered to meet the rigorous demands of chemical manufacturing plants. This system delivers complete water recovery and solid salt crystallization, enabling your facility to achieve true zero liquid discharge (ZLD) while minimizing operational costs. With a factory spanning 10,000–30,000 square meters and over 200 skilled employees, we bring unmatched expertise to every project.
The forced evaporation crystallizer utilizes a robust forced circulation design combined with efficient heat transfer to concentrate and crystallize wastewater streams. It is ideal for treating high-salinity, high-conductivity effluents common in chemical processes, such as mother liquor, brine, and reaction byproducts. By integrating advanced mechanical vapor recompression (MVR) technology, our system reduces energy consumption by up to 60% compared to traditional single-effect evaporators, making it a sustainable and cost-effective solution.
Key Features and Benefits:
- High Efficiency Evaporation: Forced circulation ensures uniform heat transfer and prevents scaling, achieving evaporation rates of 500–50,000 L/h.
- Zero Liquid Discharge Compliance: Recovers over 99% of water as high-quality distillate, leaving only dry or slurry solids for easy disposal or reuse.
- Energy-Saving MVR Technology: Mechanical vapor recompression drastically lowers steam consumption; optional thermal vapor recompression (TVR) also available.
- Corrosion-Resistant Construction: All wetted parts made from stainless steel 316L or titanium alloy, suitable for aggressive chemical environments.
- Fully Automatic Control: PLC-based system with HMI touch screen allows real-time monitoring of temperature, pressure, level, and conductivity.
- Compact Footprint: Modular design saves floor space, easy to retrofit into existing plant layouts.
- Low Maintenance: Anti-fouling design and self-cleaning cycles reduce downtime; optional CIP system available.

Frequently Asked Questions (FAQ):
-
What types of wastewater can this crystallizer handle?
It is designed for high-salinity, high-TDS streams such as RO concentrate, brine, mother liquor, and industrial effluents with pH 2–12. For corrosive chemicals, titanium or Hastelloy options are available. -
How does forced evaporation differ from natural circulation?
Forced circulation uses a pump to maintain high velocity across the heat exchanger, reducing scaling and fouling, resulting in higher heat transfer coefficients and longer operation cycles. -
What is the typical energy consumption per ton of water evaporated?
With MVR technology, energy consumption is as low as 30–60 kWh per ton of water evaporated, depending on the feed concentration and temperature. Without MVR, steam consumption is roughly 0.4–0.6 tons of steam per ton of water. -
Can the system achieve zero liquid discharge?
Yes, the crystallizer is a core component of a ZLD train. It concentrates the brine until solids precipitate, and the condensed water is reused. The final solid can be disposed of or sold as byproduct. -
How long does installation and commissioning take?
Installation typically takes 2–4 weeks, and commissioning 1–2 weeks, depending on site conditions. We provide on-site technical support and training. -
What maintenance is required?
Regular inspection of pumps, seals, and heat exchanger surfaces is recommended. Our system includes an automatic cleaning cycle to reduce manual intervention. Spare parts are readily available. -
Is the system customizable for different capacities?
Absolutely. We offer capacities from 500 L/h to 50,000 L/h, and can design multi-effect or hybrid configurations to match your specific feed composition and space constraints. -
Do you offer a warranty?
Yes, we provide a standard 12-month warranty from the date of commissioning, with extended warranty options available. Our service team is available 24/7 for urgent inquiries.
