Hydrocyclone Oil Separators
Highly efficient oil droplet separation
Ready for efficient oil removal? Cleanawater's hydrocyclone systems are more effective than traditional oil water separators.
Harnessing centrifugal force up to 1,000 times the strength of gravity, they're engineered to remove oil droplets down to 10-15 microns – as well as other hydrocarbons and surfactants.
Our extensive range includes options capable of handling 3,000 to 500,000+ litres per hour. Each model complies with all regulatory bodies – including local and regional water authorities. And they exceed all mining environmental discharge standards.
Uses and applications
- Mining
- Trade waste treatment
- Transformer bunds
- Workshops
- Wash pads
- Dairies
- Re-fuelling areas

Benefits of hydrocyclone oil water separators
- Removes oil droplets down to 10-15 microns
- Low operating costs
- Exceed water authority requirements for hydrocarbon discharge
- Pre-plumbed and pre-wired
- Suitable for use in a wide range of industries
- Available upgrades to suit hazardous areas
- Lowest maintenance systems on the market
- One-off purchase with working life of 20+ years
- Relatively small footprint (compared with traditional separators)
- Automated – low operating costs
- Durable stainless steel construction
Cleanawater hydrocyclone oil water separators are engineered to efficiently remove oil droplets down to 10-15 microns; traditional coalescing oil separators function between 40-60 microns.
With automated functionality, they can run unsupervised. They require virtually no maintenance and have low energy usage – reducing operating costs. Ideal for use in mining, they're also well-suited to workshops, wash pads, dairies and re-fuelling areas.
Our hydrocyclone systems offer discharge standards that exceed water authority requirements – helping you avoid costly fines from authorities. And because they come pre-plumbed and pre-wired, you'll save on installation costs. It also means they're ideal for retrofits and temporary sites.

Frequently asked questions
How do hydrocyclone oil separators work?
Wastewater enters the cyclone chamber and is spun under extreme centrifugal forces up to 1,000 times the force of gravity. This force causes water and oil droplets to separate.
The heavier water phase is forced outward towards the cyclone wall and the lighter oil phase migrates towards the centre core.
The separated oil is discharged from one end of the cyclone and treated water is discharged through the opposite end for further treatment, filtration or discharge.
What size hydrocyclone oil separator do I need?
This will depend on the application. For small, single-pressure washer applications a 3,000 litre per hour system is generally ideal. Larger systems are sized based on flow rates, rainfall ingression allowances and storage capacity (among other factors).
Call Cleanawater on 1800 353 788 to discuss which size will best suit your requirements.
Do you provide hydrocyclone system installation?
Yes. Call 1800 353 788 for information on installation in your area.
Do I need anything other than a hydrocyclone oil separator?
This will depend on your layout and discharge requirements. Standard packages include a non-emulsifying pump, float switches, waste oil decant tank, galvanised skid and a control panel.
They come pre-wired and pre-plumbed for plug and play installation.
Will a hydrocyclone separator remove emulsified oils?
No. However, our range of hydrocarbon treatment systems can effectively remove emulsified oils.
Do I need a permit to install an oil separator?
It's likely – however, the requirements vary between local authorities. Call 1800 353 788 or contact your local authority to confirm.
