Featuring equalization, oil separation, coagulation, and biological treatment processes, the system is designed for starch- and oil-rich food wastewater, providing stable treatment performance for 150 m³/day production discharge.
Product Parameters
This project was developed for a food manufacturing facility in Huaibei, Anhui Province, with a customized wastewater treatment system designed for instant noodle production wastewater. The system has a designed capacity of 150 m³/day, suitable for continuous food processing operations with fluctuating wastewater characteristics.
The complete treatment process includes:
Production wastewater collection → Oil separation and sedimentation → Equalization tank → pH adjustment → Coagulation & flocculation → A/O biological treatment → Sand and activated carbon filtration → Compliant discharge
The system is specifically designed to treat wastewater generated from instant noodle production processes, including starch residues, flour particles, edible oils, sugars, and suspended organic matter. The treatment process helps reduce COD, BOD, turbidity, and other key pollutants while addressing common challenges associated with food wastewater, such as foaming tendency, sediment accumulation, and high biological loading.
The equipment integrates a fully automatic PLC control system with functions including automatic chemical dosing, sludge discharge control, and scheduled backwashing. With strong load adaptability, stable operation, and standardized sludge management, the system is suitable for food factories requiring continuous production support and simplified maintenance.
Application Scenarios
This wastewater treatment system is suitable for food processing enterprises including instant noodle manufacturers, noodle production plants, bakery facilities, grain-based food factories, and other food production sites.
It is mainly applied for treating organic wastewater generated from:
- Raw material washing
- Dough mixing equipment cleaning
- Production line rinsing
- Workshop floor cleaning
- Product washing processes
Food processing wastewater generally contains high concentrations of starch, oil, and biodegradable organic substances. Without proper treatment, it may cause pipeline blockage, odor generation, water quality deterioration, and difficulties in meeting environmental discharge requirements.
The system is suitable for:
- New wastewater treatment station construction
- Existing wastewater system upgrades
- Environmental compliance improvement projects
- Food production wastewater optimization programs
Project Case Description
Anhui Huaibei has a developed food processing industry, and instant noodle manufacturing generates continuous organic wastewater during production activities such as equipment cleaning, raw material residue washing, and workshop sanitation.
This type of wastewater contains flour starch, edible oil, soluble sugars, and suspended solids. Due to its high organic content and strong biodegradability, untreated discharge may lead to rapid fermentation, pipeline sediment accumulation, odor issues, and increased environmental management pressure.
Based on the factory’s daily wastewater volume of 150 m³/day, food wastewater characteristics, and local environmental requirements, Baihuipu designed a customized treatment solution focused on stable operation, efficient pollutant reduction, and practical maintenance.
The collected wastewater first enters the oil separation and sedimentation unit, where floating oils and larger starch particles are separated to reduce the organic load entering the following treatment stages. The wastewater then flows into the equalization tank, where variations in flow rate and pollutant concentration caused by production schedules are balanced, helping maintain stable operation of the entire system.
After conditioning, the wastewater undergoes coagulation and flocculation treatment. Specialized chemicals promote the aggregation of fine starch particles, organic colloids, and suspended pollutants into larger flocs, allowing effective solid-liquid separation. This stage contributes to the reduction of COD and turbidity before biological treatment.
The pretreated wastewater then enters the A/O biological treatment system. Through the activity of adapted microbial communities, dissolved organic substances, sugars, and residual pollutants are further degraded, improving overall effluent quality. The treated water subsequently passes through sand and activated carbon filtration units, which help remove remaining fine particles, color, and trace impurities, supporting stable discharge performance.
After operation, the integrated wastewater treatment system provides automated management, convenient maintenance, and consistent treatment results. The system is designed to match the continuous production characteristics of food factories while supporting proper sludge handling and environmental compliance.
The project provides a practical wastewater management solution for instant noodle manufacturers in Huaibei, helping food enterprises improve production sustainability, optimize resource utilization, and maintain stable environmental performance.
