# Oil Water Separator Calculator Online

## Introduction

The Oil-Water Separator Calculator is a handy tool designed to calculate the volume of a separator needed to segregate oil from water effectively. This calculator is particularly beneficial in various industries where oil-water mixtures are generated, and a separation process is necessary for waste management, environmental conservation, or re-use of these resources.

## Working Principle

The calculator operates on the basic principles of separation, primarily gravity separation. Oil and water have different densities, with oil being less dense than water. This difference allows for gravity separation, where oil floats to the surface when the mixture is left undisturbed. The segregated oil can then be skimmed or removed, and the volume required for this separation process is what the calculator computes.

In addition to gravity separation, other factors like the mixture’s residence time in the separator and the coalescence process are also crucial. The residence time refers to the contact duration between the oil-water mixture and the separator. A longer residence time allows better separation, giving enough time for the oil to rise to the surface.

Coalescence refers to the process where small oil droplets merge into larger ones, making them easier to separate from the water phase. Some oil-water separators incorporate coalescing elements to enhance the separation process.

## Formula and Calculator Usage

The formula used in the Oil-Water Separator Calculator is straightforward. The separator volume is calculated by multiplying the flow rate of the oil-water mixture by the residence time. In mathematical terms, the formula is:

Separator Volume = Flow Rate * Residence Time

For instance, if we have a flow rate of 5 cubic meters per hour (m³/h) and a residence time of 3 hours (h), the required separator volume will be:

Separator Volume = 5 m³/h * 3 h = 15 cubic meters (m³)

To use the calculator, you need to enter the values for the flow rate and residence time in their respective fields and then click the ‘Calculate’ button. The calculator will then provide the separator volume based on the input data. If the entered values are invalid or zero, an error message is displayed, prompting you to enter valid values. There is also a ‘Reset’ button that clears all input fields, allowing you to perform new calculations.
