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 Pollution

1. 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

& Benefits Features

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.
