Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents the Automatic PLC Controlled 304 Stainless Steel Wastewater Treatment Plant, specifically engineered to handle ultra-high-strength effluent with COD levels up to 40,000 mg/L at a daily capacity of 10 cubic meters. As a direct manufacturer with over a decade of experience (established in 2015) and a factory spanning 10,000–30,000 square meters, we deliver robust, reliable, and fully automated solutions for industries facing extreme organic loads. This system combines durable 304 stainless steel construction with advanced PLC automation, ensuring consistent treatment performance and minimal manual intervention.
Our treatment plant is designed to tackle challenging effluents from food processing, chemical manufacturing, pharmaceutical, and textile industries. With a treatment process that integrates primary sedimentation, biological treatment, and advanced oxidation, it achieves effective pollutant reduction even under variable inflow conditions. The PLC (Programmable Logic Controller) enables real-time monitoring of key parameters like pH, dissolved oxygen, and flow rate, automatically adjusting aeration and chemical dosing for optimal efficiency.
Below we detail the technical specifications, key features, and measurable benefits that make this system a smart investment for high-strength wastewater management.
Key Features & Technical Specifications

Frequently Asked Questions (FAQ)
-
What is the typical footprint of the 10 m³/day plant?
The modular skid occupies approximately 20 m² (5m × 4m). Additional space for chemical storage and sludge handling is recommended. -
Can the PLC system be integrated with existing SCADA?
Yes, our PLC supports Modbus RTU/TCP protocols. Remote monitoring via Ethernet or 4G is available as an option. -
What is the expected lifespan of the 304 stainless steel tanks?
With proper maintenance and neutral pH operation, the lifespan exceeds 15 years. For highly corrosive effluents, we offer 316L stainless steel upgrade. -
Do you provide installation supervision?
Yes, our engineer can travel to your site for commissioning (travel expenses apply). We also offer online video guidance for simple installations. -
How long does production take after ordering?
Standard lead time is 30–45 working days, depending on customization and raw material availability. -
What payment terms do you accept?
We accept T/T (30% deposit, 70% before shipment), L/C at sight, or other negotiable terms for long-term partners. -
Can the plant handle intermittent flow (e.g., 8-hour batches)?
Yes, the system includes an equalization tank and PLC logic that adapts to batch discharge schedules. The design can be optimized for your specific flow pattern. -
What certifications does the product itself hold?
Our production line is certified under ISO9001, ISO14000, OHSAS18001, and others. Individual units can be CE marked or certified per requested standards (cost applied).
