What to Do When Palm Oil Mill Effluent Fails to Meet Discharge Standards?
As the most widely produced vegetable oil globally, palm oil generates wastewater—known as Palm Oil Mill Effluent (POME)—during processing that poses a significant challenge for environmental management. POME contains high concentrations of organic matter, suspended solids, and oils/fats; if improperly treated, its Chemical Oxygen Demand (COD) can reach 50,000–100,000 mg/L, far exceeding discharge standards. With environmental regulations becoming increasingly stringent, how can palm oil mills ensure compliance? This is a pressing issue for many processing enterprises. Drawing on the technical expertise of Henan Huatai Cereals & Oils Machinery Co., Ltd., this article provides a detailed analysis of solutions for achieving compliance in palm oil wastewater treatment.
Characteristics and Treatment Challenges of Palm Oil Wastewater
Palm oil wastewater primarily originates from processes such as pressing and refining. It is characterized by extremely high organic matter concentrations, deep coloration, and high acidity. Research indicates that POME typically has a COD of 50,000–100,000 mg/L, a Biochemical Oxygen Demand (BOD) of 25,000–50,000 mg/L, and Total Suspended Solids (TSS) ranging from 18,000 to 54,000 mg/L. Direct discharge of such wastewater would cause severe damage to aquatic ecosystems.

Backed by a professional engineering team, the company tailors solutions to ensure compliance based on specific influent water quality and discharge standards.
System Solutions for Compliant Palm Oil Wastewater Discharge
To address the issue of palm oil mill wastewater failing to meet discharge standards, the following systematic solution is recommended:
Step 1: Pretreatment Optimization. Utilize screens, equalization tanks, and filtration processes to initially remove scum and the majority of suspended solids, thereby reducing the load on subsequent treatment stages. Huatai Oil Machinery’s pretreatment equipment effectively recovers residual oil from the wastewater, enabling resource recovery.
Step 2: Enhanced Biochemical Treatment. Employ a combined process featuring UASB reactors and A/O systems to remove the vast majority of organic matter through microbial degradation. The anaerobic stage also allows for biogas recovery, which can be used for facility heating or power generation, thereby lowering operating costs.
Step 3: Advanced Treatment for Compliance. Depending on discharge standards, advanced treatment technologies such as coagulation-sedimentation, membrane filtration, or advanced oxidation can be selected. For enterprises requiring water reuse, reverse osmosis (RO) membrane systems can be employed to produce high-quality reclaimed water that meets standards for boiler feed water or process water.
Step 4: Resource Utilization. Leverage by-products generated during treatment—such as biogas and recovered oil—to turn waste into value and enhance the project’s overall economic efficiency.
