Used Oil Recycling

The recycling of waste oil not only contributes to environmental protection but also has significant economic value. In particular, industrial waste oil and used motor oil collected and recycled can be restored to its original state through the refining process. Thus effectively promote the recycling of used oil. Achieve the goal of energy conservation.

ZK SEPARATION Decanters for Used Oil Recycling Process

ZK waste oil recycling centrifuge is solid-liquid separation equipment specially developed to process and recycle industrial waste oil, motor oil, and used cooking oil. ZK decanter has continuous two-phase and three-phase separation and strong processing capacity, which can recover about 80-90% of oil (related to oil density, demulsification effect, temperature, etc.), and the slag phase after centrifuge separation. The degree can reach 40-60%, and the total volume is reduced by more than 80% compared to before separation. It can efficiently separate the light phase (oil phase) and heavy phase (water and sludge).
