Oil/Water Separator Manufacturer | Industrial Water …

Effective separation & treatment is possible for any non-emulsified product with a specific gravity less than 1.0, which is lighter than water. Industrial oil/water separators are a simple and effective tool for any wastewater treatment process that requires oil & grease removal because gravity is the driving force for the separation.

FL gravity & density separators for minerals

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.

Compact Separation

Separation at high pressure. Caltec has developed and patented our own I-SEP® compact separation technologies which can be used to separate two phases of differing density of liquids and/or solids. This is done in-line, and at the process operating pressure. I-SEP® encourages the process fluid to rotate with a specially engineered involute.

Liquid / Gas Separation Technology

In a gravity separator or knock-out drum, gravitational forces control separation. The lower the gas velocity and the larger the vessel size, the more efficient the liquid/gas separation. Because of the large vessel size required to achieve settling, gravity separators are rarely designed to remove droplets smaller than 300 microns⁴.

Gravity Separation

Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation, and is normally a wet process although examples of dry gravity separators exist. Gravity separation works best when there is a large difference in the SG in the minerals to be separated, and the particle size is similar and not excessively fine, and shape is rounded.
