Coalescing Plate Oil Water Separator

Baldwin Industrial Systems designs and manufactures coalescing plate oil-water separators that remove oil, sludge, and suspended solids from industrial wastewater. Each system is engineered for high separation efficiency, minimal maintenance, and long-term adherence to Australian environmental standards.

Engineered for consistent, compliant wastewater treatment.

Coalescing plate separators form a core part of Baldwin’s wastewater treatment products. They help prevent contamination, reduce operational downtime, and support sites in meeting EPA discharge requirements across mining, petroleum, manufacturing, transport, and utilities sectors.

Units are available for above-ground or in-ground installation, with flow capacities ranging from 1,000 L/hr to 500,000 L/hr.

Simple process. Advanced plate design.

Baldwin separators use a physical separation method that enhances natural oil rise velocity using inclined coalescing plates.

Step-by-Step Process

1. Flow enters the separator and passes through a bank of inclined coalescing plates.
   
2. Oil droplets collide and combine (coalesce), forming larger droplets.
   
3. As droplets grow, they rise to the surface where oil is collected for removal.
   
4. Heavier solids sink to the bottom, forming a sludge layer for periodic clean-out.
   

This design increases separation efficiency while maintaining low operating and maintenance costs.

Versatile systems for industrial use.

Baldwin coalescing plate separators are suited to a wide range of industries and wastewater types, including:

• Mining and resources
• Petroleum depots and refineries
• Railway workshops and wash bays
• Power stations and tank farms
• Mechanical and maintenance facilities
• Stormwater and bund-water treatment

Each system is fully scalable to site flow rates and discharge requirements.

Engineered for efficiency and longevity.

• Scientifically proven oil-water separation technology
  
• Customisable systems for variable site conditions and water quality
  
• Durable stainless-steel construction
  
• Factory-tested before delivery
  

Optional floating suction skimmers, feed pumps, control panels, polishing media, waste oil tanks and access platforms

Built for a sustainable future.

Just one litre of oil can pollute a million litres of water.
