The wastewater from the oil palm mill includes the discharge of oil, water and impurities, condensed water from high-temperature cooking of fruit bunches, and equipment cleaning water. Wastewater accounts for about 70%-75% of the fresh fruit bunches entering the factory. The oil content is about 1%, including a large amount of emulsified oil components. Multiple oil extraction systems can convert most of the emulsified oil into floating oil and extract it through advanced equipment. The wastewater oil extraction system can reduce more than 80% of the oil waste in the wastewater. The overall process is simple, the degree of automation is high, the cost is low, and the loss of oil in the wastewater is greatly reduced, while also reducing the concentration of pollutants discharged in the wastewater.

A large part of the oil loss in palm oil mills comes from the fruit fiber, which is the fiber product after being squeezed by the oil press, and the oil content is generally around 5%. Solution The full-process leaching and extraction process of the fruit fiber can reduce the remaining oil in the fruit fiber to less than 1%. The remaining oil can be fully extracted to meet the crude oil standard, and the overall production cost is low. After the oil extraction is completed, the fruit fiber can still be used as fuel to meet the steam supply required by the original process and the new process.

The empty fruit bunches that have been cooked at high temperature contain a large amount of condensed water and a certain amount of oil. Our company has developed an integrated crushing, extrusion and dehydration equipment for this situation. It can effectively squeeze out the oily wastewater and extract the oil through the oil-water separation system.
