Key Features & Benefits
- 304 Stainless Steel Construction – Resistant to rust, acids, and alkalis, ensuring a service life of over 15 years even in harsh environments.
- PLC Automatic Control – The programmable logic controller monitors and adjusts parameters such as flow rate, pH, dissolved oxygen, and sludge level in real time. Remote monitoring and alarm functions are optional.
- Multi-stage Treatment Process – Combines physical filtration, biological treatment, chemical dosing, and membrane separation (if required) to achieve effluent quality that meets local discharge or reuse standards.
- Energy-saving Design – Low-power pumps and intelligent energy management reduce operating costs by up to 30% compared to traditional systems.
- Compact Footprint – Skid-mounted or containerized design minimizes installation space and allows easy relocation.
- Low Maintenance – Self-cleaning filters, automatic sludge discharge, and corrosion-proof materials drastically reduce manual upkeep.
- Customizable Capacity – Available in standard models from 10 m³/day to 500 m³/day, with larger capacities available upon request.
- Global Certifications – Our factory is certified under ISO9001, ISO14001, OHSAS18001, and many other international standards, ensuring product quality and safety.

Detailed Product Advantages
Superior Corrosion Resistance: 304 stainless steel contains 18% chromium and 8% nickel, forming a protective oxide layer. This makes the equipment ideal for treating acidic, alkaline, or saline industrial wastewater without pitting or rusting.
Intelligent PLC Control: The automatic control system can store multiple treatment recipes for different wastewater types. Operators simply select the recipe and the system will adjust aeration, dosing, and filtration cycles accordingly. Remote monitoring via Ethernet or GSM is available, allowing you to check operation status from anywhere.
Efficient Biological Treatment: The system incorporates an advanced biofilm reactor (MBBR) or activated sludge process, achieving over 90% removal of BOD, COD, and suspended solids. For high-concentration wastewater, optional anaerobic pretreatment can be added.
Cost Savings: Because the equipment is fully automatic, you save on labor costs. The energy-efficient design reduces electricity consumption, and the durable materials minimize replacement parts. Payback period is typically within 2–3 years for most industrial facilities.
Easy Installation & Commissioning: Our equipment is pre-assembled and tested in our factory. On-site installation typically takes 1–3 days, and our engineers can provide remote or on-site commissioning support.

Q: What is the typical treatment capacity range for a standard model?
A: Our standard models range from 10 m³/day to 500 m³/day. For larger flows, we design multi-unit systems or custom-built solutions. -
Q: Do you provide installation and commissioning services?
A: Yes, we offer both remote guidance and on-site installation support. Our engineers can travel to your site, or we can send a detailed installation manual. We also provide training for your operators. -
Q: What is the lead time for this equipment?
A: Lead time depends on the capacity and customization level. Standard units typically ship within 30–45 days after order confirmation. Custom designs may take 60–90 days. -
Q: Can the PLC control system be integrated with existing SCADA or DCS?
A: Yes, our PLC supports Modbus, Profibus, and Ethernet/IP protocols, allowing easy integration with most industrial automation systems. -
Q: What maintenance is required?
A: Routine maintenance includes checking pumps, aerators, and sludge discharge. The self-cleaning filters require minimal attention. We recommend a monthly inspection and annual professional service. A maintenance contract is available. -
Q: Is the equipment compliant with international standards?
A: Yes, our manufacturing facilities are certified to ISO9001, ISO14001, and OHSAS18001. The equipment can be designed to meet EU, US, or local effluent standards. Please provide your target discharge limits for customized compliance. -
