Treating water with respect since 1982

Ultraspin Oil water separator

Oily Water Separators

Full range of oil water separators to treat oil droplet sizes from less than 15 micron to more than 150 micron, at flows 1.0  600 m3/hr and higher

Ultraspin oil skimmer

Oil Skimmers

Fully self-adjusting weir type skimmer captures all types of oils, fats and grease  fast!

Ultraspin Technology design and supply high performance oily water separators.

Our systems utilise innovative hydrocyclone technology to separate oils, fats, grease and solids from contaminated water. Based in Melbourne, we’re the largest oily water equipment supplier in Australia. Ultraspin’s leading edge technology is a high powered, low maintenance alternative to other traditional forms of oily water treatment, such as coalescing plate separators, air floatation and large retention tanks in and above ground.

The Ultraspin Oily Water Separator

How does the Oily Water Separator work?

A spinning vortex is created by pumping the oily water tangentially into a cone-shaped separator. This creates a powerful centrifugal force, that accelerates as it moves down the cone. These strong forces separate the heavier water component to the outside of the vortex while the lighter oil droplets are forced to the centre. The separated oils are removed through an orifice at the inlet end of the cone and treated water is discharged through the opposite end.

Why is it such a powerful separator?

The centrifugal force generated inside the vortex of the Ultraspin oil separator is in the order of 1,000 times the force of gravity! With such force, effective oily wastewater treatment can be achieved even with emulsified oil droplets as small as 15 microns. Other oil water separators, like coalescing plate packs, petrol interceptors, tanks or similar oil separators, depend on the effects of gravity for oil separation and consequently are less efficient and can be a lot slower. With an Ultraspin Separator you will have a high performance, reliable, low risk system that requires very little maintenance. Take the stress out of ensuring your wastewater system will work by giving us a call. We will work with you to design a complete system of oily water treatment with no hidden surprises.

What micron rating oil separator do I need?

The first and most important thing to know when treating oily water is your oil droplet size. The droplet size in your water determines the micron rating you will need for your oil separator.

Ultraspin helps you understand your oily water
The micron rating of your oily water separator will need to be less than your oil droplet size. The smaller the oil droplets of your oily water, the more powerful (lower micron rating) your separator needs to be. Some separators are less powerful and are only designed to treat large, easy to separate oil droplets and therefore have a large micron rating. Make sure you select a separator powerful enough for your oil droplet size. There is no such thing as a ‘one size fits all’ separator!

The Best Way – Measure Your Oil Droplets!

The best and most accurate way to calculate the size of the oil droplets in your water is to measure them directly, on site.

Samples sent to a laboratory will not be accurate (because the droplet size will change in transit and you’ll get an incorrect result).

The most accurate technology available for measuring droplet size is a video particle analyser. Video technology is accurate and can tell the difference between an oil droplet and a solid particle. This is what Ultraspin uses to measure our clients’ droplet sizes. Ultraspin also has a portable video particle analyser and skilled operators who can bring it to site to measure your droplet size and oil distribution ‘live’ in the wastewater. It is vital to have both an accurate oil droplet measuring tool capable of telling the difference between oil droplets, air bubbles and suspended solids AND a skilled operator experienced in oily water analysis. Ultraspin has the best of both! So if you would like our help please let us know. There is no more guesswork required.

Ultraspin can analyse your oily water characteristics
The single most important factor when choosing a separator is knowing your droplet size. The oil droplet size (in microns) determines which separator types will work for your application, how powerful the separator needs to be and how many stages of treatment you will need. The most accurate way to work out your droplet size is to take samples and measure it. If that’s not possible, there are several reliable ways to estimate.
There are various separator technologies on the market, which use different methods of separation. Each is designed and rated to treat a different micron size. For example, gravity systems treat 150 micron and larger (cannot separate small droplets), whereas membranes treat 25 micron and below (cannot treat large droplets or oil slugs).
Spend wisely! Find out the hidden costs for running an oily water separator. From crane hire, to fire proofing, to engineering fees for calculating affects on the water table – find out what most suppliers won’t tell you! We break down the numbers for running your oily water separator, so you know exactly what to expect before you buy and don’t get any nasty surprises.
We know you only want to deal with a quality supplier with the experience to deliver the results you need. How do you know if a vendor has the credibility to backup their oily water claims? Ask for the numbers!
