Zero Discharge Sewage Treatment Plant Stainless Steel 316L With Remote Monitoring System
Product Spotlights
As a leading manufacturer since 2015, Qingdao Conqinphi Environmental Technology Group Co., Ltd. is proud to present our Zero Discharge Sewage Treatment Plant constructed from premium Stainless Steel 316L and equipped with an advanced Remote Monitoring System. This system is designed to achieve complete water reuse while eliminating any liquid discharge, addressing the strictest environmental regulations. With a factory size of 10,000–30,000 square meters and an annual export value exceeding US$10 million, we deliver reliable, high-performance solutions trusted by clients across North America, Europe, Asia, and beyond.
Our zero discharge technology integrates multiple treatment stages, including biological treatment, membrane filtration, and evaporation, to recover over 99% of water from sewage. The 316L stainless steel construction ensures exceptional corrosion resistance, even in harsh chemical environments, providing a service life of more than 20 years. The embedded remote monitoring system enables real-time data acquisition, alarm management, and remote control via web or mobile app, reducing operational costs and downtime.
Key Features
- Zero Liquid Discharge (ZLD): Achieves complete water recycling, producing solid waste for safe disposal, complying with zero-discharge regulations.
- 316L Stainless Steel Construction: Superior resistance to pitting, crevice corrosion, and chloride stress cracking, ideal for saline and industrial wastewater.
- Remote Monitoring System: Real-time monitoring of flow, pH, TDS, pressure, and fault alerts via cloud platform, supports 24/7 unmanned operation.
- Modular & Compact Design: Skid-mounted or containerized units, easy to transport and install, expandable for future capacity upgrades.
- Energy-Efficient Process: Low-power pumps, optimized aeration, and heat recovery reduce energy consumption by up to 30% compared to traditional ZLD systems.
- Low Maintenance: Automatic cleaning of membrane modules, corrosion-resistant materials, and remote diagnostics minimize manual intervention.

Frequently Asked Questions
Q1: What is the typical payback period for this system?
A: Depending on water prices and local regulations, most clients achieve payback within 2–4 years. The exact period depends on your specific water usage and discharge costs.
Q2: Can the remote monitoring system be integrated with existing SCADA systems?
A: Yes, our system supports standard communication protocols (Modbus TCP, OPC UA) and can be customized to integrate with your existing control infrastructure.
Q3: What power source is required?
A: Standard equipment runs on 380V/50Hz three-phase power. We can adapt to 480V/60Hz or other voltages upon request.
Q4: Do you provide installation and commissioning support?
A: Absolutely. We offer optional on-site supervision by our engineers, as well as remote commissioning guidance. Training for your operators is included.
Q5: What is the lifespan of the system?
A: With proper maintenance, the 316L stainless steel structure and components can last over 20 years. Membrane modules typically require replacement every 3–5 years.
Q6: How does the system handle fluctuating inlet conditions?
A: The PLC-controlled process automatically adjusts flow rates, chemical dosing, and membrane operation to maintain stable effluent quality even with varying loads.
Q7: Is the system compliant with international standards?
A: Yes, our factory is certified under ISO9001, ISO14000, OHSAS18001, and SA8000. The equipment can be designed to meet local discharge standards such as EU, EPA, or GB requirements.
Q8: Can I get a sample system for testing before purchase?
A: We offer pilot-scale units (1–5 m³/day) for on-site trials. Please contact us to discuss rental or purchase options for the pilot system.
