Here at Ultraspin, we would like to take this opportunity to thank you for purchasing an Ultraspin Oil

Skimmer.

Over the years we have designed and supplied high performance oily water separation systems to a

variety of industries. Our systems use innovative hydrocyclone technology to separate oils, fats and

solids from process and effluent streams. These separation systems are the result of research and

development programs started in 1983 by the company Engineers. At that time Ultraspin staff

designed the world’s first successful oil removal hydrocyclone systems. There have been many

innovations and process developments since then and these form the core of current Ultraspin

designs.

We greatly appreciate your business and the opportunity to assist you. Your satisfaction is the

greatest recognition we could ask for and we invite you to give us your feedback on our product and

services.

For any queries regarding the Oil Skimmer and any other Ultraspin related products please refer to

1. System Overview

1.1 Description

Skimmers are designed to remove oil, fats and floating material from tanks, pits and open waters.

Ultraspin skimmers are true self-adjusting, weir-type, oily water skimmers and are an important part

of oily water treatment systems.

IMPORTANT: It is important to understand that no type or brand of oil skimmer is a water treatment device. Removing free floating oil does not treat the water that lies below. Whilst an oil skimmer may form a part of an overall water treatment strategy – if the primary problem is cleaning the water, then water treatment equipment is needed and not just an oil skimmer

1.1.1 Oil Recovery

After the skimming process it may be necessary to drain the excess water and collect concentrated

oil. For this purpose Ultraspin is able to provide the Oil Recovery System (ORS). These packaged

systems include a pump, skimmer, hose and collection tank.

1.1.2 Water Treatment Systems

Ultraspin Skimmers are able to collect all contents of an oily water pit or tank regardless of oil

composition and the addition of surfactants. They do not distinguish between fluid types and

therefore do not treat the water. The skimmers can be used in conjunction with Ultraspin Water

treatment systems capable of improving water quality through their unique water treatment

process.

For more information regarding the Oil Recovery System please refer to http://www.ultraspin.com.au/index.php/products/oil-recovery-system

1.3 How does it work?

The main components of the Ultraspin skimmer are a floating central ring, flexible bellows and a

floating body assembly. The floating central ring sits in the centre of the skimmer with the bellows

forming a sealed chamber between the body and the central ring. The flexibility in the bellows

allows the ring to float independently of the skimmer body; this gives the skimmer its ability to self-

adjust. The ring floats on the fluid in the pump-out chamber on the inside of the bellows. The body

of the skimmer holds the components together and provides the floatation for the assembly.

A hose and pump are connected to the skimmer outlet. As the fluid is pumped away the floating ring

sinks, thus allowing fluid to flow over the top and into the pump-out chamber. As the flow is

increased the ring sinks deeper into the fluid so that more fluid passes over the top of the ring and

into the pump-out chamber, making the skimmer fully self-adjusting.

1.4 Typical Applications

Ultraspin skimmers have been successfully employed in a large number of applications. Some

examples are shown below.

Dairy Factory Ultraspin skimmers are used in dairy factory waste water pits. They provide the feed to Ultraspin dairy treatment systems.

Mining Industry Skimmers are often used in the clean-up of oil spills and feeding to treatment systems from oily water collection pits from heavy mine vehicle re-fuelling and maintenance operations.

Food Processing Plant Ultraspin skimmers are able to work effectively in fat and oil collection tanks despite the contents of the tank solidifying in cold weather.

Other Applications

Oil Skimming from effluent collection pits, tanks and interceptors

Oil spill clean-up

As part of oily water separator systems

Providing skimmed feed to oily water treatment systems

5. Installation of the Oil Skimmers 1. Connect the suction hose to the pump or the connection pipe in the tank.

This may be done permanently with a flanged connection or via a Camlock style quick

connection

2. Ensure that the skimmer does not wedge under or against items inside the tank as the level rises

and falls

3. Place the skimmer on the surface of the fluid to be treated

The skimmer is to be installed with the suction hose connection on base of skimmer

4. Prime the skimmer before drawing fluid through

Leave the skimmer to float for 5 minutes. It will slowly fill with fluid through the 12mm hole

in the base. It will be ready for operation once the fluid inside the floating weir ring is visible

and at the same level as the surrounding fluid

5. Once the skimmer is primed, start the suction pump

Correct operation causes fluid to be drawn evenly between the floats and across the weir

ring, which will have submerged slightly.

S1 and S2 skimmers are used in conjunction with all Ultraspin treatment systems. The figure below

shows how the installation of an Ultraspin Oil Skimmer aids in the process and function of the

Ultraspin Oil Recovery System.

6. Routine Maintenance The only routine care normally required for the skimmer is a periodic clean. No further

adjustments are needed.

To clean the skimmer, carefully remove it from the tank or pit. This may require lifting

apparatus.

Built up trash and sediment can be removed with a low-pressure clean water hose.

The cleaning frequency will depend on the site conditions.

Ensure there are no blockages at bottom chamber where hose is connected and the priming

hole is located.

7. Skimmer Spare Parts

7.1 Parts Replacement

The bellows and weir ring assembly can be removed by loosening the lower ring clamp.

The weir ring is removed from the bellows by undoing the upper ring clamp.

Reassembly is the reverse of disassembly, keeping in mind that, to prevent damage to the

ring, the ring clamp securing diaphragm to weir ring should not be excessively tightened.
