The coalescer and separator elements are specifically designed for oil-water separation systems, suitable for treating oil-water mixtures, suspensions, and emulsions.
The operating sequence within the system consists of five stages: solid-liquid separation → demulsification → coalescence → separation → adsorption. A higher ratio of coalescing elements to separating elements improves coalescence efficiency and accelerates the separation rate.
Coalescer & Separator – Principle of Operation
The coalescer & separator is engineered for liquid-liquid separation and incorporates two primary elements: a coalescing element and a separating element.
Coalescing Stage
Oil enters the coalescing element, where solid particulates are retained and micron-sized water droplets are coalesced into larger globules. Most enlarged globules settle by gravity into the collection sump and are discharged via the drain valve.
Separation Stage
The oil then passes through the separating element. With oleophilic and hydrophobic media, the element allows oil to pass freely while repelling residual water, which collects in the sedimentation tank and is drained. Clean, water-free oil exits the outlet.
Differential Pressure Monitoring
As contaminants accumulate on the filter elements, differential pressure rises. When it reaches 0.15 MPa, the coalescing element is clogged and requires replacement.
Performance Features
Easy Installation – Simple assembly and disassembly for quick, labor-saving maintenance.
High Dirt-Holding Capacity – Multi-layer media with uniform pleating extends service life.
Robust Construction – Sturdy inner core delivers high strength and reliable pressure resistance.
Efficient Filtration – Low flow resistance and high flow rate support large-volume applications.
Reliable Precision – Effective removal of fine particulates ensures system cleanliness.
Applications
Hydraulic and lube oil filtration for industrial machinery
Liquid purification, separation, and recovery in processing industries
Compressed air treatment and oil/water removal
Pre-filtration for water treatment and pharmaceutical processes
Filtration for power generation, railway, marine, and heavy-duty vehicles
