Qingdao Conqinphi Environmental Technology Group Co., Ltd. is a leading manufacturer established in 2015, specializing in advanced water treatment solutions. Our Zero Discharge Sewage Treatment Plant for Food Processing Industry Effluent Reuse is engineered to help food processors achieve sustainable water management, reduce operational costs, and comply with stringent environmental regulations. With a factory size of 10,000–30,000 square meters and annual export value exceeding US$10 million, we deliver reliable, high-performance systems trusted by clients across North America, Europe, Southeast Asia, and beyond.
This integrated system combines membrane bioreactor (MBR), reverse osmosis (RO), and advanced oxidation technologies to achieve zero liquid discharge (ZLD), converting food processing wastewater into high-quality reusable water. It is designed to handle high organic loads, fats, oils, and greases (FOG), and varying pH levels typical in the food industry. The result: up to 98% water recovery with minimal waste generation, meeting stringent effluent reuse standards.
Key Features & Technical Specifications
- Zero Discharge Design: No liquid effluent discharged; all water recovered for reuse, reducing water footprint and disposal costs.
- Multi-Stage Treatment: Includes primary screening, oil/grease separation, biological treatment (MBR), membrane filtration (UF/RO), and final polishing.
- High Organic Load Tolerance: Handles COD up to 10,000 mg/L and BOD up to 5,000 mg/L without system upset.
- Automated PLC Control: Touch-screen interface with remote monitoring capability, ensuring consistent operation with minimal operator intervention.
- Compact Footprint: Skid-mounted or containerized options available for easy installation and scalability.
- Energy Efficient: Low energy consumption per cubic meter of treated water, with optional solar integration.
- Corrosion-Resistant Materials: Stainless steel and anti-corrosion coatings for long service life in harsh environments.
- Compliance with Global Standards: Manufactured under ISO9001, ISO14000, HACCP, and OHSAS18001 certified facilities.

Frequently Asked Questions
-
Q: What types of food processing wastewater can this system treat?
A: It is suitable for effluent from meat, poultry, seafood, dairy, fruit & vegetable, beverage, and edible oil processing, among others. We customize the pre-treatment stage based on the specific contaminants. -
Q: How long does installation typically take?
A: Installation time varies by system size and site conditions, but typical skid-mounted units can be commissioned within 2–4 weeks. Larger projects may require 6–8 weeks. -
Q: What is the expected lifespan of the membranes?
A: With proper maintenance, MBR membranes typically last 5–8 years, and RO membranes 3–5 years. Our system includes automatic cleaning protocols to extend membrane life. -
Q: Can the system handle fluctuating flow rates?
A: Yes, the system incorporates equalization tanks and PLC-controlled variable frequency drives to accommodate daily and seasonal variations in flow and load. -
Q: What is the quality of the reused water?
A: The treated water meets or exceeds standards for process water, irrigation, and cooling tower makeup. Specific parameters (e.g., conductivity, hardness) can be customized per your requirements. -
Q: Do you provide training for operators?
A: Yes, we offer comprehensive on-site training for your team, covering system operation, maintenance, and troubleshooting. Remote support is also available. -
Q: What certifications does your company hold?
