How it works
For an oil in water system, the two mixed liquids are pumped into the separator unit,
which contains the internal coalescing media. The internal media are composed of both oleophilic (oil attracting) and oleophobic (oil repelling) surfaces. Physical separation between oil and water droplets occur in the surfaces of the media, followed by rapid coalescing effect of all individual liquid droplets, before exiting the final internal media.
Typically the increase of oil droplet diameter is in the range of 100+ fold. From test data, a 10 micron or smaller diameter oil droplet can be easily increased to 1000 micron of larger. This results in a steady rise of all oil droplets from the water phase, in the range of 2 inches per second or better. As this coalescing phenomenon continues, a clear boundary layer is created between oil and water, which allows final complete separation of oil from water.
The above phenomenon and theory also hold true for water in oil system. This time only the control sensors and control valve locations are different.
The Outstanding Features of the oil-water separator are as follows:
Feed Variations
No limit for feed compositions, the oil-water separator can handle clost to 100% oil or close to 100% water,
or any percent in between.
High Efficiency
Under most circumstances, separation efficiency of less then 10 ppm contaminant of free oil in water, or free water in oil is achievable. This separator will meet discharge permit for most cities, states or open water discharge requirements.
Easy Operation
With control sensors and valve, this separator is 100% automated, unattended operation is possible in any location.
High Capacity
Apollo oil-water separator can handle liquid flow rate as low as 1/2 gallon per minute, or as large as 10,000 gallons per minute, or any size in between.
Low Maintenance
No filter media and cartridges need to be replaced or disposed of. The oil water separator media will last many years of continuous service. Annual inspection and minimum clean up of these media (if debris is present) may be required.
High Quality
Vessel and housing units can be manufactured according to latest version of ASME code. For corrosion consideration, various vessel materials can be specified, including carbon steel, stainless steel, high alloys and fiberglass, etc.
Design Versatility
Custom designs can fulfill any specific needs you may have, concerning liquid-liquid separators. Our separators can incorporate internal heating elements, working upstreams of reverse osmosis, activated carbon beds, electro-dialysis unit and ultra centrifuged unit etc.
Application Areas
Any liquid source consists of two or more immiscible liquid phases., eg oil and water. With design modifications, the oil-water separator can tolerate the presence of one gas phase and up to 10% solids in the liquid streams.
Heavy Metal Removal Option
Very often a waste stream may contain oil, grease, suspended solids and some trace amount of heavy metal ions. These ions may include mercury, lead, zinc, chromium, cadmium, arsenic, colbalt and copper etc. The removal of these and other heavy metal ions from waste stream often requires expensive process such as reverse osmosis, electrodialysis or ion exchange equipments. Not only is the initial equipment cost high, sometimes the process may not be practical at all. mainly due to the huge quantity of the waste that has to be treated, especially when the liquid stream is dirty.
We have an alternative solution for the removal of the trace amount of heavy metal ions in the waste stream.
In our process, a specially treated organoclay material is used. It has the capacity to remove most heavy metal ions from water. We can provide on single pass separator, that can treat the waste stream at high separation efficiency, to remove not only for oil and grease, but also for most heavy metal ions as well.
Soil remediation and reclamation process
Contaminated solid sediments commonly found the bottom of storage tanks, waste pits and lagoons, often present environmental problems to many industries.
The most common soil remediation method today is a solvent washing process. This calls for extensive use of chemical solvents to wash the sediments, followed by solid-liquid and oil-water separations. Very often roaster and VOC destruction towers are required, before the treated solid sediments are acceptable for reclamation. This method has two shortcomings: namely the extensive use of
chemicals and energy, as well as the costly operation and maintenance of large quantities of equipments
Other soil remediation methods make use of oil digesting bacteria, treated inside a bio-reactor or bio-pond. But the end results are often mixed, depending largely on the existence of favorable weather conditions, the pH and nutrient content inside the bio-pond is too long to make this method a practical choice for a viable operation.
Our soil remediation process, an enzyme solution, together with a greatly reduced amount of solvent are used. Very often after the first washing cycle of the sediments is completed, the solids are already being cleaned enough and ready for reclamation. After further enzyme treatment, if required, most tough and highly contaminated soil sediments can be legally reclaimed by our enzyme process, which is simple and effective.
