Vertical Gravity Separators (VGS)
Highly efficient removal of free oils from water
Ready for efficient oil removal? Cleanawater's VGS systems are designed to outperform traditional oil water separators.
They efficiently remove free oils and grease from water – making them effective in a range of industrial and commercial settings. Their small footprint and optional hot water handling unit make them ideal for commercial kitchens. But they're equally adept at removing oil from industrial waste water or wash-down water. And you can look forward to a long service life thanks to easy maintenance and a durable stainless steel construction.

Cleanawater VGS systems are designed to help you comply with water authority discharge standards for oil and grease removal.
Thanks to their lightweight construction and small footprint, they're quickly and easily installed. That means your system can be up and running in no time.
We offer complete, compact systems ideal for limited space; the VGS' small footprint requires far less floorspace than a coalescing separator. And they're supplied with non-emulsifying pumps, float switches and controllers – everything you need to get up and running.
We can supply a customised VGS to suit your site requirements, industry and budget – with any capacity from 700L to 3,000L per hour.
Built from durable stainless steel with durability in mind, they're adaptable enough to handle hot oils and grease – perfect for hospitality applications. The units' automated operation requires no consumables – saving on material costs. And our VGS design allows on-line maintenance, meaning minimal operational downtime.

Vertical gravity separators (VGSs) work on the principle of liquid density and coalescence. Oily water is fed into the VGS' chamber at the top of the unit. Upon meeting the stationary water volume inside the chamber, the velocity of flow is reduced and suspended solids in the water that have a higher density to water, begin to drop out. These collect in the sump at the bottom of the unit.
Oil that has a lower density to water begins to rise to the top of the unit. Inclined plates in the form of a series of cones are placed in the path of these rising oil droplets (commonly referred to as a SPAK). The droplets collide and collect on these plates. When enough oil droplets collect and merge together, they become more buoyant and rise to the surface quickly. At the surface, an integrated skimmer takes away the oil to a waste oil collection drum. Treated water is directed out the side of the unit with oil removed.
This depends on a variety of factors including budget, location, flow rates and oily water properties. Call Cleanawater on 1800 353 788 and we'll be happy to advise on the best system for you.
Gravity flow systems are available, however, traditionally a specifically sized non-emulsifying pump will pump oily water through an oil water separator for treatment. Discharge may be connected to sewer, leach drains, evaporation ponds, stormwater (with permit only) holding tanks or other approved discharge points.
Yes. Call Cleanawater on 1800 353 788 to hear about installation services in your location.
This will depend on your layout and discharge requirements. Standard packages include a non-emulsifying pump, float switches, waste oil drum, galvanised support frame and a control panel.
Every 3-6 months, generally. This depends on the amount of sludge accumulated in your process and oil influent levels.
Non-emulsifying, low shear pumps such as diaphragm pumps or helical rotor pumps must be used at all times.
Yes. Our units are constructed from stainless steel or polyethylene which are ideal for outdoor environments.
Sewerage pump stations collect sewerage and pump it to the municipal system. Buy a simple plug and play unit or customise a larger unit for your needs
