Heavy-Duty Sewage Treatment System: Complete Engineering Solutions
1. Product Overview & Engineering Standard
Our heavy-duty wastewater treatment equipment is engineered specifically for high-strength, toxic, and complex industrial effluent. Unlike standard domestic systems, this multi-stage physical-chemical and advanced biological plant breaks down hard-to-treat chemical pollutants, heavy metals, and emulsified oils.
The equipment purifies heavily fouled factory discharge, turning it into compliant water for surface disposal or high-quality recycled water for internal factory reuse. The entire system features a robust, modular design that integrates smoothly into active industrial chemical lines, textile mills, and food manufacturing plants.

6. Real-World Case Study: Zero Fines for a Chemical Plant
The Industrial Client: A large-scale resin and chemical manufacturing plant.
The Effluent Problem: The factory generated process wastewater containing high levels of non-biodegradable chemicals and phenols. Raw water COD spiked frequently to 4,500 mg/L. Local authorities issued suspension notices due to river pollution.
Our Engineered Solution: We custom-built a 400 \(m^{3}\)/day industrial wastewater treatment equipment system. The custom package combined chemical coagulation, a DAF micro-bubble separator, an anaerobic bio-bed, and final Reverse Osmosis (RO) filtration.
The Final Outcome: The factory achieved complete compliance within two weeks of commissioning. Effluent COD dropped below 40 mg/L, totally avoiding heavy environmental fines. Furthermore, the plant now recycles 75% of the clean RO output back into production washing lines, slashing raw water consumption significantly.
7. Frequently Asked Questions (FAQ)
Q1: Can your sewage treatment system handle sudden spikes in daily water flow?
Yes. Every system includes an integrated equalization tank mechanism. Smart PLC liquid-level sensors manage the internal flow rate. This configuration balances high morning or evening water surges. It protects the helpful bacteria inside the biological tank from washing away, ensuring stable performance.
Q2: What is the standard production timeline for a custom system?
Standard skid-mounted setups (under 200 \(m^{3}\)/day) take 25 to 30 days to build. Large, high-capacity, or highly customized industrial container plants require 45 to 60 days. This timeline includes structural fabrication, interior piping assembly, PLC electrical programming, and final hydraulic pressure tests.
Q3: How much daily work does it take to maintain this machine?
Very little. Because the system uses fully automated PLC control loops, it runs mostly unattended. Your local factory workers do not need advanced technical training. They only need to spend 15 to 30 minutes a day conducting basic visual checks, verifying chemical tank levels, and writing down sensor numbers.
Q4: How long do the integrated MBR membrane filters last?
Under standard operating conditions, our high-quality PVDF membrane sheets last between 3 to 5 years. The smart PLC runs regular, automated cleanings using tiny air bubbles and backwash fluids. This routine keeps the filter pores clear and extends the module's operational lifespan.
