Recover around 30 L of oil per hour.
Keep water content in the recovered oil low.
An edible-oil producer used an S100 to remove the surface oil film after neutralisation in its collection tank. Calculations in the case study indicated approximately 30 litres of oil recovered per hour. The recovered vegetable oil contained very little water and could be reused in industrial applications.
Case Background
Process water became contaminated with vegetable oil at several stages of production. The existing wastewater-treatment system did not separate oil and water sufficiently.
The Problem
The existing wastewater-treatment system did not separate oil and water sufficiently, leaving the wastewater inadequately cleaned. At the same time, the recovered oil had the potential to be reused in a variety of industrial applications.
Because the previous separation system was inefficient, the collected oil contained too much water. Evaporating that water required excessive energy, while the high temperatures needed also degraded the quality of the vegetable oil. The plant therefore needed an efficient and sustainable mechanical solution for separating oil from wastewater.

Results
Current calculations show that the S100 discharges approximately 30 litres of oil per hour into the collection tank. The customer is highly satisfied with the result.
The S100 provides a simple and sustainable way to keep the wastewater free of oil. The separated vegetable oil contains very little water and can be reused in various industrial applications.
With its flexible collection-tube length, the powerful S100 is particularly well suited to large settling tanks. Durable stainless-steel and ceramic components make the unit easy to maintain and suitable even for chemically aggressive process baths.

High oil content in your process water and too much water in recovered vegetable oil?
Please share your process-water flow rate, vegetable oil type and temperature, collection-basin dimensions, oil-layer thickness, liquid-level fluctuations and target oil concentration. Our China engineering team can recommend an S100 oil skimmer, collection tube and recovery-tank configuration for your operating conditions.
