How Does it Work?
● 1000 times force of gravity
● No moving parts● Separator requires no
cleaning

Types of Oil Pollution1. Free Oil●Free floating oil OR●Oil droplets greater than 150 micron.●Free oil can separate by Gravity.
2. Emulsified Oil●Oil droplets less than 150 micron AND●Oil droplets greater than 2 micron●Emulsified oil must be treated with a more powerful separator.
3. Dissolved Oil●Oil droplets less than 2 micron OR●Physically dissolved in the water.●Dissolved oil will NOT be treated by conventional gravity, plate pack type systems.
4. Heavy Oil●Oil with density >1●Oil Stuck to heavy solids

Lowest Ownership Costs
● When making an investment you need to consider the total cost of ownership over the lifetime of your investment:
● Installation, ● Operation and ● Maintenance
● After only 5 years, Ultraspin systems can be HALF THE COST.

Our Experience
● ~ 800 oily water treatment systems installed.
● ~ 27 billion litres of water treated ~ 75 % of the yearly water
usage of the City Of Sydney .
● Reclaiming about 5 billion litres of water per year.
