Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015, is a professional manufacturer specializing in zero-liquid-discharge (ZLD) solutions. With a factory area of 10,000-30,000 square meters and an annual export value of US$10-50 million, we serve diverse markets worldwide. Our Zero Liquid Discharge High Salt Wastewater Treatment, Forced Circulation Evaporator & Crystallizer System is designed to efficiently treat high-salinity wastewater, recovering clean water and valuable salts while achieving complete effluent elimination.
This system leverages forced circulation evaporation and crystallization technology to handle challenging brines with minimal scaling and fouling. It offers exceptional energy efficiency, robust automation, and flexible customization to meet various industrial requirements. Whether you need to treat reverse osmosis concentrate, chemical wastewater, or brine from desalination, our system delivers reliable performance and compliance with strict environmental standards.
Below we detail the key features, technical specifications, advantages, and common questions answered to help you understand why this system is a trusted choice for ZLD applications.
Key Features & Technical Details
- Forced Circulation Design: Prevents scaling and fouling by maintaining high flow velocity across the heat exchanger, ensuring stable operation even with high salt concentrations.
- Efficient Crystallization: The crystallizer produces large, uniform crystals that are easy to separate and dewater, reducing downstream processing costs.
- Low Energy Consumption: Incorporates mechanical vapor recompression (MVR) or multi-effect evaporation (MED) options to minimize steam and power usage.
- Corrosion-Resistant Materials: Main wetted parts are made from SS316L or duplex stainless steel (optional), providing long service life in aggressive brine environments.
- Fully Automated PLC Control: Touch-screen interface with remote monitoring capability allows for unattended operation and real-time data logging.
- Compact Footprint: Modular skid-mounted design reduces installation space and simplifies on-site assembly.
- Customizable Capacity & Configuration: Systems can be tailored for flow rates from 1 m³/h to over 100 m³/h, with multi-stage configurations available.

Frequently Asked Questions
Q: What types of wastewater can this system handle?
A: It is designed for high-salinity streams such as RO concentrate, chemical process brine, textile dyeing effluent, landfill leachate, and produced water from oil & gas. The forced circulation design handles TDS up to 250,000 mg/L and can process feed with high scaling potential.
Q: What is the typical water recovery rate?
A: The system can achieve over 95% water recovery as distillate, depending on the feed composition and desired salt quality. The remaining concentrated brine is crystallized to solid salt, achieving true zero liquid discharge.
Q: How much energy does the system consume?
A: Energy consumption varies based on evaporation load and chosen technology. With MVR, typical specific power consumption is 30-60 kWh per ton of evaporated water. For steam-driven MED, consumption is about 0.2-0.4 tons of steam per ton of evaporation. We provide detailed energy calculations during project evaluation.
Q: What maintenance is required?
A: Routine maintenance includes regular inspection of pumps, valves, heat exchangers, and crystallizers. The forced circulation reduces scaling, so cleaning intervals are typically longer than with natural circulation systems. We provide a maintenance manual and recommend scheduled check-ups. On-site training is available.
Q: Can the system be customized for different capacities or site conditions?
A: Yes, absolutely. We offer modular designs that can be scaled from 1 to 100+ m³/h. Material of construction, heating method, control level, and auxiliary equipment (e.g., dewatering centrifuge, dryer) are all customizable to match your requirements. We work closely with you during the design phase.
Q: How long is the delivery time?
A: Typical lead time ranges from 8 to 16 weeks after order confirmation, depending on complexity and current production load. We offer expedited options for urgently needed projects. Please inquire with your specific timeline.
Q: Do you provide installation and commissioning services?
A: Yes, we can send experienced engineers to supervise installation and perform commissioning at your site. We also offer remote support via video call. Post-commissioning, we provide training for your operators and a standard 12-month warranty with optional extensions.
Q: What certifications does the system meet?
A: Our company is certified under ISO9001, ISO14001, OHSAS18001, and other standards. The equipment itself can be designed to comply with local regulations such as CE, ASME, or GB standards upon request. We provide necessary documentation for project approval.
