As a professional manufacturer established in 2015, Qingdao Conqinphi Environmental Technology Group Co., Ltd. offers advanced Zero Discharge High-Salt Wastewater Treatment Equipment designed to achieve complete liquid elimination and solid recovery. Our system is backed by test reports and a long-life membrane guarantee, ensuring reliable performance and minimal maintenance. With over 200 employees and a factory spanning 10,000-30,000 square meters, we deliver industrial-grade solutions for challenging high-salinity streams.
This equipment utilizes multi-stage membrane technology (RO/NF/DTRO) combined with evaporation/crystallization to achieve zero liquid discharge (ZLD). It effectively treats brine, RO concentrate, and industrial effluents with TDS up to 200,000 mg/L, recovering over 95% of water as high-purity reusable water while producing only dry salts.
Key Features & Technical Benefits
- Long-Life Membrane Guarantee: Membrane lifespan ≥3 years under standard conditions, reducing replacement costs by up to 40%.
- Zero Discharge Compliance: Meets stringent environmental regulations for wastewater discharge, eliminating fines and protecting water bodies.
- Test Report Provided: Every unit comes with a detailed performance test report, verifying salt rejection, water recovery, and energy consumption.
- Customizable Capacity: Available from 1 m³/h to 100 m³/h, tailored to your specific flow rate and salt concentration.
- Fully Automated PLC Control: Touch-screen HMI with remote monitoring, real-time alarms, and data logging.
- Robust Construction: Corrosion-resistant materials (stainless steel 316L, FRP, PVC) ensure durability in harsh chemical environments.
- High Recovery Rate: Up to 95% water recovery, reducing freshwater consumption and lowering operational costs.
- Energy Efficiency: Energy recovery devices (ERDs) and optimized pump design reduce power consumption by 15-30% compared to conventional systems.
