Because oil and water really do mix, industries look for a simple, cost-efficient, low maintenance device to separate them. The HYDRASEP® Oil Water Separator incorporates all new technology that results in a quicker, more effective method of separating oily water mixtures while saving maintenance costs.
System Principle
HYDRASEP® introduces the "Bubble Spin" principle for the separation of immiscible liquids. Inclined or coalescing plate separators are designed based on Stoke's Law. Stoke's Law defines separation of fluids not in motion. HYDRASEP® is specifically designed for fluids in motion. The dynamics of motion impose an external force on the suspended particles, which causes the particles to spin, breaking their bond with the carrying liquid. Thus the particles will cluster together and form their own layer at a predetermined height.
System Description
The animation on our home page shows the HYDRASEP® separator process and its main internal components. The contaminated liquid is introduced into the "mixture" section where heavy solids are allowed to settle. The mixture then enters the "separator" section, which consists of a serpentine series of channels subdivided into multiple parallel sub-channels.
These channels are specifically designed to control the velocity of the fluids (thus eliminating turbulence) and provide the required time for a particle to separate itself from the carrying liquid. An internally built "accumulator" regulates and dampens fluid surges in the flow. It works in conjunction with the channels to optimize the effects of the external forces imposed on the particles, thus improving the separation process.
The "oil recovery" section is designed to prevent separated liquids from remixing. Recovered oil can be removed without interfering with the operation of the separator. The "clean water" section is designed to allow effluent to be discharged, recycled, or transferred to further treatment. All sections of the HYDRASEP® separator are specifically designed to work as an integrated system to provide the highest quality of gravity separation.

Major Advantages
- Simplicity of operation; uses no filters, meshes or coalescing plates
- Constant removal of oil to avoid overflow conditions
- Minimum maintenance; saving labor and parts costs
- Operates as a continuous or intermittent flow separator
- No possibility of remixing of "clean water" with separated oils
HYDRASEP® Options:
- HYDRAPASS® - In large surface-area stormwater run-off, the "first flush" entrains the majority of the contaminants. The patented HYDRAPASS® can be used in conjunction with the HYDRASEP® to ensure that the "first flush" is treated and that excess flows are by-passed. The HYDRAPASS/HYDRASEP combination provides an economical effective storm water run-off treatment.
