A newly established dairy processing plant in Indonesia needed to treat wastewater containing high concentrations of organic pollutants, fats, oils and grease (FOG), suspended solids, and nutrients generated during the production process. After reviewing the influent data and site layout drawings, Yimei proposed a customized wastewater treatment solution that met the client's budget while ensuring stable discharge standards and long-term operational reliability required for dairy processing. Leveraging our advanced technology, engineers were able to provide accurate quotations and detailed design drawings, enabling the client to clearly understand the final outcome before project commencement.

Creating a Customized Wastewater Treatment Solution

Every dairy production facility has unique wastewater characteristics depending on its processing capacity, cleaning procedures, and production requirements. Based on a detailed assessment of the customer's wastewater quality, production process, and discharge standards, Yimei designed a targeted wastewater treatment system to achieve efficient and stable operation.

Key Challenges of Dairy Wastewater Treatment:

• High COD and BOD concentrations 
• Large amounts of fats, oils, and grease (FOG) 
• Fluctuating wastewater flow rates 
• Strict wastewater discharge requirements 
• Limited installation space 

By addressing these challenges, the designed system provides an optimized treatment process that improves pollutant removal efficiency while reducing operating and maintenance costs.

The system combines multiple advanced treatment technologies:

1. Equalization Tank

Balances wastewater flow and stabilizes pollutant concentrations before treatment.

2. Dissolved Air Flotation (DAF) System

Removes fats, oils, grease, and suspended solids with high efficiency, reducing the load on downstream biological treatment processes.

3. Biological Treatment Process

Utilizes advanced microbial activity to effectively reduce COD, BOD, and ammonia nitrogen while ensuring stable operation.

4. Secondary Clarification

Separates treated water from activated sludge and improves final effluent quality.

5. Sludge Dewatering System

Reduces sludge volume, lowers disposal costs, and improves overall operational efficiency.

The entire system was manufactured in Qingdao Yimei using corrosion-resistant materials and industrial-grade components to ensure durability under tropical operating conditions.
