How do the Ultraspin Oil Water Separators work?

Like many oily water separators, the Ultraspin system separates the oil/fat and the water based on the density difference – the oil/fat droplets being lighter than the water. To do this the oily wastewater is pumped tangentially into the separator which forms a powerful vortex and huge centrifugal forces. This squeezes the lighter oil/fat droplets into the center of the vortex. Two streams are generated: treated water ready for discharge or reuse, and the separated oil for storage and disposal.

  • The centrifugal separation force generated is over 1000 times the force of gravity!
  • Separates emulsified oil droplets as small as 10 microns!

The Ultraspin separator is one of the simplest and most powerful oil water separators available. And all with no consumables and no chemicals!

A powerful oil separator – with a complete package

With an Ultraspin oil water separator you get high performance with a reliable, low risk system that requires very little maintenance. This is achieved because with Ultraspin you get a complete system that includes large strainers, oil skimmers, large oil storage decant tanks and control equipment as standard; no surprises and you know exactly what your costs will be.

Skimmers to remove surface level oils

Oil Skimmers

The Ultraspin oil skimmer is an important part of many of our oil water separators. Why do we like them so much?

  • Greatly improve the overall water discharge quality
  • Minimise the risk of oil spills if the pit floods (no oil on top to overflow)
  • Reduces flammable risk – no oil on top to catch fire
  • Less pit pump-outs when no oil gets built up
  • Eliminates nasty odours

Our skimmers are floating self-adjusting weir style which means if there are fluctuations in water flow or the skimmer tilts, it will adjust itself automatically and operate as normal. Find out more by visiting our Skimmer page

Strainers – bigger is better

Our systems include very large, high capacity easy clean strainers. 30 years experience tells us a strainer is essential for protecting the pump and other equipment from wear and damage. All kinds of debris collects in an oily water pits; leaves and twigs, cigarette butts, feathers, food packets, cable ties, even beetles and other insects!

Our customers really like our large strainers – it’s a great advantage of our systems. Particularly as most competitor oil water separators do not come with a strainer at all, meaning their equipment gets damaged quickly – forcing downtime and requiring costly spare parts.

Ultraspin strainers are designed with the operator in mind:

  • Large capacity – reduce the frequency of emptying and monitoring
  • Quick and easy to clean
  • No heavy lifting or bending over, can be cleaned by one person without any special tools
  • Robust perforated stainless steel (not mesh) so debris doesn’t get stuck or damage the strainer

Oil Storage Tanks – Size Matters

Ultraspin designs feature large oil storage tanks. The objective of an oil water separator is to remove oil – and lots of it. Many of our competitors don’t supply an oil tank, and when they do, its tiny! The Ultraspin separator is powerful, separating lots of oil, and larger tank gives you the convenience of emptying it less often, and no more constantly checking to see if it’s over-flowing. In addition, we fit our oil tanks with an automatic water drain. Separated oil from oily water treatment systems of all types always contains a large percentage of water in addition to the recovered oil. This is true for every oily water separator technology on the market. Decanting this water will save you a lot of money in waste disposal fees.

VBO Tank – Water Polishing

Some contaminants cannot be mechanically separated, some common examples are listed below. Our VBO Tank is a simple and cost-effective way to treat these contaminants. If you have strict discharge requirements, then a VBO Tank is a good way to ensure you are consistently compliant. Furthermore if you are struggling with a shortage of fresh water onsite and plan to reuse treated water then you need a VBO Tank to keep the water fresh. Without VBO treatment before reuse the treated water will produce foul odours, hazardous off-gases and scum build up.

Oil Water Aeration
Nice and gentle pumps for oil separators

Low Shear Pumps

Pumps are a very important part of an oil water separator and we are very fussy about pump selection. A poor pump can be very detrimental to the performance of an oil water separator. By using our oil droplet particle sizer we quickly identify pumps that ‘shear’ or chop up the oil droplets, emulsifying the oily water, and making oil separation more difficult. Most vendors don’t have equipment to measure oil droplet particle size and therefore often select pumps purely on cost. This results in poor oil water separator performance and a costly mistake for their customers.

At Ultraspin we design, select and performance test (with one of our oil droplet size tools) all of our pumps to make sure that they are gentle on the oily water and give the very best possible oil water discharge quality. Its one of the many reasons our systems work so well. With this philosophy we are able to offer pneumatic and electric pumps to suit your application. Different materials are also available to suit the application.

Clever Controls

We provide pneumatic and electric control systems that can be manual or fully automatic. We also include additional control features for some customers such as:

Start up Recycle: Allows the removal of thick oil layers before treating and discharging water. Multiple treatment of water to increase overall oil separation efficiency when oil droplets are very small or higher water quality discharge is required.

Choosing an Oil Water Separator

If you’re not an oily water expert don’t worry. In our Learning Centre we have put together a wealth of information that will turn you into an expert in no time!

The Importance of Oil Droplet Micron Rating

The single most important thing when selecting an oil water separator is knowing its oil droplet size micron rating. Large oil droplets are easy to separate and most separators will do that, but if your oily water mixture contains smaller oil droplets you will need a more powerful separator with a lower micron rating.

Are you confused by the capabilities of Coalescing Plate Separators, VGS, European ‘5 mg/l’ tanks, DAF’s, Media filters or centrifuges? We can provide some information to help you decide.
