Our coalescing plate oil water separator units are designed to be simple yet efficient tools that perform oil and water separation, as well as the capture of other contaminants from wastewater.

An increase in society’s environmental awareness has developed through technological advancement and our evolved social conscience, leading to the use of oil and water separators in a variety of contexts in which grease and suspended solids can be found.

No longer are oil separators limited to industrial uses in mines, petrol stations and treatment plants. Coalescing plate oil water separators are also widely employed in situations such as:

mining workshops

Mining Workshops

Petroleum Refineries

  • paint manufacturers
  • mining wash bays
  • petroleum depots
  • oil and gas stormwater treatment
  • tank farms
  • bund water treatment
  • railway wash bays
  • mechanical workshops

Businesses of all sizes are adopting their use in their effort to contribute to the preservation and sustainability of our planet, by engaging in effective oil and water separation practices.

Baldwin Industrial Systems are among the leading Australian suppliers of premium quality oil water separator units.

Our oil water separators are scalable treatment systems that can be designed for large or small water flow rates, and meet a range of effluent discharge qualities as required.

We offer both above-ground and in-ground oil water separators, as well as custom-made units and accessories to complement our oil water separators, depending on the best solution for your application.

Additional equipment and options can be supplied in conjunction with our oil water separators upon request. These include:

  • Feed pumps
  • Control panels – from Form 1 to Form 3B MCC
  • Floating suction skimmers and strainers
  • Polishing media
  • Skid mounting
  • Pre-plumbed – stainless steel or pressure PVC
  • Pre-cabled
  • Factory Acceptance Tested
  • Waste oil tanks
  • Access platforms
FLOW RATE CAPACITY up to 500,000 litres/hour

Baldwin oil and water separators have numerous advantages which make them the preferred choice across our diverse customer base. No matter the context or size of your application – here are some key reasons why you should choose our oil and water separators:

  • They provide a scientifically proven method for removing and recycling oil cost-effectively
  • They are versatile and customisable (catering to a broad range of water quality limits depending on the application)
  • They are sturdy, reliable and require minimal maintenance


Having decades of experience within the industry, we know that the coalescing plates found within the separator play an important part in oil separation, carrying out the bulk of the oil and water segregation. For this reason it is critical to choose a separator that is based on a scientifically proven performance calculation and a known plate surface area.

We have designed and manufactured the products in our oil water separator range with flow rate capacities ranging from 1,000 litres per hour to over 500,000 litres per hour, based on our proprietary knowledge.

There’s no need to let the separating of oil and water become an even messier job.

What are the flow rate capacities of your coalescing plate separators?

Baldwin has designed and manufactured oil-water separators with flow rate capacities ranging from 1,000 litres per hour to over 500,000 litres per hour.

Do I need an oil water separator?

Our oil water separator units are used by companies of all sizes, from mechanical workshops and service stations to petrol refineries and power stations. Contact us to discuss your options.

How do coalescing separators work?

Coalescing plate separator packs are positioned in two stages to encourage free oil droplets to impinge on the surface. Droplets rise to the top as they come into contact with the media packs and are skimmed off into a waste oil container.

How do I know a coalescing system is right for my operation?

This is dependent on a number of variables, including budget, location, flow rates, and the composition of oily water. Get in touch with us at (02) 4954 0440 and we will advise on the best coalescing system for you.

Do you provide coalescing separator installation?

Baldwin fabricates stainless steel clarifiers that are ready to transport to the site for ease of installation and integration into a wider treatment system. Get in touch with us at (02) 4954 0440 to confirm whether we can supply installation in your area.

How often do coalescing oil separators require servicing?

In most cases, it’s every 3-6 months. However, this is dependent on the amount of sludge that has been collected in your process as well as the degree of oil influent levels.

What are the advantages of Baldwin Coalescing Plate Separators?
  • Each system is individually designed for each application based on proven design principles and is guaranteed to meet the stringent new discharge laws being imposed by local authorities.
  • Modular construction ensures that retrofitting outdated triple interceptors and API systems are efficient and cost effective methods of upgrading.
  • Baldwin ‘V-Plates’ are assembled in a vertical configuration, such that “clogging” or “silting up” is virtually eliminated.
  • Unique proprietary design enables the corrugated plates to be uniformly spaced at either 6mm or 12mm
  • Injection moulded Polypropylene Plates are highly “oleophilic” and extremely resistant to most chemicals.
