Oil Separators

Introduction

At Roto we offer a large range of tanks, including oil tanks. Our smallest tank at 400 litres can be placed almost anywhere, but also offer tanks up to 50,000L for the larger application. Roto are here to help, so if you require guidance, we have a team set up that can talk you though the process.

Separator Classes

Class I
Designed to achieve a concentration of less than 5mg/l of oil under standard test conditions and should be used when the separator is required to remove very small oil droplets. A coalescence filter insert is installed before the drain to improve the separating effect in the separator. When the water flows through, tiny oil drops combine to form large drops which then leave the coalescence material. With oil separators a special inlet system has a plug-flow effect in the separator. This slows the flow down and distributes it in a hydraulically effective way over the separator space. The heavy materials sink to the bottom and are separated out, the light materials rise to the top and are separated off there.

Class II
Designed to achieve a concentration of less than 100mg/l oil under standard test conditions and are suitable for dealing with discharges where a lower quality requirement applies.

With Bypass 10% or 20%
Bypass separators fully treat all flows generated by rainfall rates of up to 6.5mm/hr. (99% of all rainfall events). These separators are used on parking area when it is considered an acceptable risk not to provide full treatment for high flows, for example where the risk of a large spillage and heavy rainfall occurring at the same time is small.

Application

Oil and coalescence separators are required where light liquids occur which is usually at the below locations:

  • Petrol and gas stations
  • Car washes
  • Vehicle workshops
  • Car parks

Branding

Like many companies, you want to create a product that has your own style and branding. At Roto, we are happy to help develop this with you and include your branding into the product.

Accessories

Alarm
Separators should be provided with a visual and audible oil alarm. This operates when the oil level reaches 90% of the oil storage volume and indicates that the separator needs immediate emptying for it to continue to work efficiently.

Automatic Closure Device
Full retention separators must be provided with an automatic closure device which operates in the event of a sudden surge of a quantity of oil entering the system at too high an accumulation, This device should in conjunction with the oil alarm.

Sampling Shaft
Sampling shaft makes it possible to monitor the quality of the water on the outflow.
