Filtering oily water can be done using oil-absorbent filter mats like those produced by PIG®. These mats are specifically designed to absorb oil while allowing clean water to pass through. You can simply pour the oily water through the mat, and only water will flow out.
Here are other common methods used to filter oily water:
- Oil Water Separation Filters: These filters use a variety of techniques, including gravity and filtration, to separate oil from water. They are commonly used in industrial settings, but can also be found in smaller sizes for residential use.
- Coalescing Filters: These filters utilize a process of coalescing, where small oil droplets are forced to combine into larger droplets, which are then easier to remove.
- Gravity Separation: If the oil and water are not mixed too thoroughly, gravity separation can be used to separate the two. The oil will float to the top, and the water can then be drained off.
Remember, the best method for filtering oily water will depend on the specific application and the type of oil involved. For example, if the oil is highly viscous or contains solids, specialized filtration techniques may be required.
