Mine Operations Oily Water Separators

Who are we?

●Small high tech engineering company

●Involved in water treatment since 1983

●Innovative new ways to treat water

containing oil and grease

●Sell systems to● USA● UK● Australia● New Zealand● Africa● Europe

Clients

● Mining companies● Oil companies● Power authorities

How Does it Work?

● 1000 times force of gravity

● No moving parts● Separator requires no

cleaning

How Does it Compare?

Source: The treatment of produced water in offshore rig; Comparison between traditional installations and innovative systems; F.E. Ciarapica.

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

& BenefitsFeatures

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.

Oily Water on Mine sites

● Typical uses● Mining – Workshops● Vehicle Wash / Truck wash● Refueling / Fuel Storage
