Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. — a leading manufacturer dedicated to providing sustainable wastewater solutions since 2015. Our Factory Direct Zero-Discharge Wastewater Treatment Plant is engineered to meet the highest environmental standards, ensuring complete elimination of wastewater discharge while maximizing water reuse. With a factory spanning 10,000-30,000 square meters and over 200 skilled employees, we deliver reliable, cost-effective systems backed by a Mill Test Report for every unit. Our plants are designed to comply with international norms, offering peace of mind for industries seeking regulatory compliance and operational excellence.
This advanced treatment system integrates cutting-edge evaporation, crystallization, and membrane technologies to achieve true zero liquid discharge (ZLD). Whether your industry generates high-salinity brine, heavy metal laden effluents, or organic-rich wastewater, our customizable solution safely recovers up to 95% of water and converts remaining solids into dry cake for disposal or reuse. The plant is delivered as a pre-assembled module, reducing installation time and on-site work. Each unit undergoes rigorous factory testing, and a detailed Mill Test Report is provided to verify performance against your specifications.
Key Features & Technical Advantages

Frequently Asked Questions (FAQ)
Q1: What does “Zero-Discharge” mean in practical terms?
A: Zero-discharge means that no liquid effluent leaves the plant. All wastewater is treated to recover clean water and generate solid salt cake or residue, which can be safely disposed of or repurposed. Our system achieves ≥95% water recovery, with the remainder removed as solids.
Q2: Can the plant handle variable influent quality and flow?
A: Yes. Our design includes equalization tanks and adaptive PLC controls that tolerate fluctuations in flow rate and pollutant loads. The system automatically adjusts operating parameters to maintain performance.
Q3: What certifications does your plant comply with?
A: Our manufacturing facility is certified under ISO9001, ISO14000, OHSAS18001, and other standards (full list available on request). The plant itself is designed to meet typical international discharge standards; however, we can customize to comply with your local regulations.
Q4: Is the Mill Test Report provided for every unit?
A: Absolutely. Each plant undergoes a full performance test at our factory before shipment. The report includes key parameters like water recovery rate, energy consumption, and effluent quality, ensuring you receive exactly what was specified.
Q5: What is the typical delivery time?
A: Depending on capacity and customization, delivery typically ranges from 45 to 90 days. We work closely with you to schedule production and shipping from Qingdao Port.
Q6: Do you offer installation and after-sales service?
A: Yes. We provide on-site commissioning supervision, training for your operators, and a one-year warranty. Remote technical support is available 24/7, and we maintain a stock of spare parts for quick delivery.
Q7: Can the system be integrated with existing wastewater infrastructure?
A: Yes. We design our plants as modular additions that can be retrofitted into your current treatment chain. Our engineers will conduct a site assessment to ensure seamless integration.
Q8: What types of wastewater are suitable for this ZLD plant?
A: It is ideal for high-salinity brine, reverse osmosis concentrate, industrial effluents from chemical, pharmaceutical, textile, food processing, mining, and electroplating industries. We customize pre-treatment steps based on your specific contaminants.
