FROM SKIMMER TO SYSTEM

When a standalone oil skimmer is only the first component

Industrial oil recovery can require additional equipment after the oil leaves the water surface. Complete systems integrate the skimmer with the equipment needed to handle the recovered oil and the installation itself.

1

Recover

A Brill® free-floating collector tube continuously removes suitable free-floating oil from the liquid surface.

2

Condition

Decanting and suitable discharge arrangements can reduce unnecessary water in the recovered-oil stream.

3

Handle

Recovered oil may need local storage, automatic transfer, containment, heating or environmental protection.

4

Integrate

Mounting, controls, tank interfaces and mobility are configured around the actual plant rather than treated as afterthoughts.

Complete Oil Skimmers ORTS oil removal and transfer skid for industrial wastewater
ORTS® OIL REMOVAL & TRANSFER SYSTEM

Skim, decant, store and transfer

Industrial wastewater · pits · sumps · steel · rail · process water

ORTS® combines the major stages of continuous oil recovery on one engineered skid. A Brill® tube skimmer removes surface oil, the integrated decanting stage reduces recovered water, the oil is held in a local tank and a transfer pump moves it to the required remote collection point.

It is particularly useful where a standalone skimmer would otherwise require separate tanks, pumps and controls to be engineered around it.

Published oil removal 4–200 US gal/h (15–757 L/h)
Main function Complete recovered-oil handling
Storage Integrated collection tank
Transfer Application-selected pump
Consider ORTS when: recovered oil needs to be decanted, stored and transferred automatically rather than simply discharged from the skimmer into a nearby container.

Oil Skimmers ESS enclosed oil skimming system for tank and manway installations
ESS® ENCLOSED SKIMMING SYSTEM

Protect and contain the oil-skimming installation

Tanks · manways · weather exposure · harsh environments · VOC-sensitive applications

ESS® places the oil-skimming components inside a purpose-built enclosure for applications where an exposed skimmer is undesirable. The system protects the equipment from wind, weather and surrounding plant conditions and can be configured as a sealed and gasketed system where vapour containment is required.

Its modular architecture combines the System Core with optional height extension and adapter plate, making it particularly useful for existing tank openings and manways.

Published oil removal 4–100 US gal/h (15–379 L/h)
Standard skimmer Model 6V
Alternative Model 7V available
Containment Sealed & gasketed when required
Weather protection Protect skimmer and controls in demanding installations.
Tank integration Custom height and adapter plate for the actual opening.
VOC containment Sealed and gasketed configurations are available where required.
Consider ESS when: the installation itself needs enclosure, environmental protection, controlled access or vapour containment.
MOBILE OIL SKIMMING SYSTEMS

One recovery system for multiple locations

Where oil accumulates periodically in several pits, tanks, sumps or ponds, mobility can make more sense than installing a dedicated skimmer at every recovery point.

Cart mounted · pallet mounted · mobile extended-reach station

Oil Skimmers offers mobile systems ranging from a compact wheeled cart through forklift-movable pallet systems to a complete Mobile Extended Reach Skimming Station with recovered-oil storage and boom-mounted skimming.

This approach can also be useful where equipment needs to be removed periodically to provide access for cleaning, maintenance or other plant operations.

Consider a Mobile System when: oil removal is required at several locations but simultaneous continuous skimming at every location is not necessary.
Configuration 1 Cart Mounted
Configuration 2 Pallet Mounted
Configuration 3 Mobile Extended Reach
Primary purpose Multiple recovery locations
Mobile Skimming Station: manufacturer configurations include recovered-oil tanks from 300–2,000 US gal (approximately 1,136–7,571 L), with the collector tube, boom and transfer equipment configured around the actual application.
QUICK SELECTION GUIDE

Start with the problem around the skimmer

The system choice becomes much easier when the downstream handling and installation requirements are defined first.

NEED STORAGE & TRANSFER? ORTS® Choose ORTS when the system must recover oil, reduce collected water, store the recovered oil and automatically transfer it.
NEED AN ENCLOSURE? ESS® Choose ESS when weather protection, tank integration, controlled access or vapour containment is the primary installation requirement.
NEED TO MOVE? Mobile Systems Choose a mobile system where one recovery package needs to serve several separate oil-collection points around the site.
Oil Skimmers Tube Test Kit for testing collector tube performance with actual oil and process liquid
TEST BEFORE FINAL SYSTEM SELECTION

Validate collector-tube performance with the actual oil

ORTS®, ESS® and many Mobile Oil Skimming Systems use the Brill® free-floating collector-tube principle. Where the oil, grease or process liquid is unusual, collector-tube pickup can be evaluated before the final system is specified.

The Tube Test Kit allows the actual contaminant and process liquid to be evaluated rather than assuming that every floating material behaves the same way.

For selected applications, Filtra can also review whether a proof-of-concept approach is appropriate before a larger system is finalized, subject to technical review and equipment availability.

APPLICATION ENGINEERING

Specify the complete recovery duty

Selecting a complete oil-skimming system requires more than estimating how much oil is on the surface.

The skimmer, collector-tube configuration, tank, transfer pump, decanting arrangement, controls, mounting and electrical package all need to match the actual process and site.

For European installations, hazardous-area and ATEX requirements should be identified at the beginning of the selection process rather than assumed from US electrical terminology.

Useful information for system selection

  • Oil, grease or floating contaminant type
  • Process liquid and temperature
  • Estimated oil quantity and accumulation rate
  • Pit, sump, tank or pond dimensions
  • Minimum and maximum liquid levels
  • Floating debris or solids
  • Required recovered-oil storage volume
  • Transfer distance and elevation
  • Available mounting positions
  • Need for an enclosure or VOC containment
  • Need for mobility between several locations
  • Indoor or outdoor installation
  • Cold-weather or heating requirements
  • Available electrical supply
  • Hazardous-area classification where applicable
NOT SURE WHICH SYSTEM?

Start with the application, not the product

Filtra International can review the oil, process water, installation geometry, storage requirements, transfer duty, mobility and environmental conditions before selecting ORTS®, ESS®, a Mobile System or another oil-removal configuration.

FREQUENTLY ASKED QUESTIONS

Oil Skimming System selection

Common questions about ORTS®, ESS® and Mobile Oil Skimming Systems.

What is an industrial oil skimming system?
An industrial oil skimming system combines the oil skimmer with additional equipment required for the application, such as oil-water decanting, recovered-oil storage, transfer pumping, controls, enclosures, mounting or mobility.
What is the difference between ORTS, ESS and a Mobile Oil Skimming System?
ORTS is designed around integrated oil recovery, decanting, storage and transfer. ESS is designed around an enclosed, protected tank or manway installation. Mobile Oil Skimming Systems are designed so one recovery package can be moved between multiple oil-skimming locations.
When should I choose ORTS?
ORTS should be considered where recovered oil needs to be skimmed, decanted, stored locally and transferred to another vessel or collection point as one integrated process.
What is the published ORTS oil-removal capacity?
Oil Skimmers currently publishes an overall ORTS oil-removal capacity of 4–200 US gal/h (15–757 L/h). Final performance depends on the skimmer configuration, oil and operating conditions.
When should I choose ESS?
ESS is particularly suitable where the oil skimmer must be enclosed for weather protection, harsh environmental conditions, controlled access, tank or manway integration or vapour containment.
Can ESS be sealed for VOC containment?
Yes. Where required by the application, the ESS enclosure can be completely sealed and gasketed to contain volatile organic compounds and other process vapours.
What is the published ESS oil-removal capacity?
The current manufacturer ESS page publishes an oil-removal capacity of 4–100 US gal/h (15–379 L/h). The Model 6V is the standard skimmer in the System Core and Model 7V is also available.
When does a Mobile Oil Skimming System make sense?
A mobile system is useful when several pits, tanks, sumps or ponds require periodic oil removal but the amount or frequency does not justify installing a permanent skimmer at every location.
What mobile oil-skimming configurations are available?
Oil Skimmers publishes Cart Mounted, Pallet Mounted and Mobile Skimming Station configurations. The appropriate system depends on how the equipment needs to move and the size of the recovery duty.
Can the mobile system include recovered-oil storage?
Yes. Larger Mobile Skimming Station configurations can incorporate a recovered-oil collection tank and transfer equipment. Manufacturer configurations include collection tanks from 300 to 2,000 US gal (approximately 1,136 to 7,571 L).
Do these systems work with changing liquid levels?
Tube-type configurations use a free-floating collector tube that follows changes in the liquid surface. The tube length, mounting geometry and system configuration must still accommodate the required operating range.
Can a complete oil skimming system operate automatically?
Depending on the selected system, controls can incorporate skimmer operation, transfer pumping, timers, tank-level switches, heating and other functions. The required automation should be defined during system engineering.
Is an oil skimming system the same as an oil-water separator?
No. An oil skimming system primarily removes free-floating oil from the liquid surface and may then handle the recovered oil. An oil-water separator is intended to treat an oily-water stream through a dedicated separation process.
Can the Tube Test Kit be used before selecting a complete system?
Yes. For suitable tube-skimming applications, collector-tube pickup can be evaluated using the actual oil and process liquid before the final ORTS, ESS or Mobile System configuration is selected.
Can these systems be used in European hazardous areas?
Potential hazardous-area applications require an application-specific review. US descriptions such as explosion proof should not automatically be interpreted as European ATEX compliance. Motors, pumps, controls, heaters and the complete system must match the actual European site classification and applicable requirements.
What information is needed to select an oil skimming system?
Useful information includes oil type, liquid temperature, oil accumulation rate, pit or tank dimensions, liquid-level range, debris conditions, storage requirements, transfer distance, mounting access, enclosure requirements, mobility requirements, electrical supply and any hazardous-area classification.
