Equipment
SPEC engineers and fabricates hydrocyclones, corrugated plate interceptors, flotation units and nutshell filters that remove dispersed oil and suspended solids from produced water for discharge or reinjection.
Over a field’s life, water often becomes the largest produced stream, and it is treated in stages.
In this category
Treatment stages are selected around oil-droplet size, solids loading, water chemistry, pressure and required discharge or reinjection specification.
Centrifugal separation using the pressure drop across the liner to drive oil to the core and out of the overflow.

Inclined plate packs shortening the rise distance so free oil coalesces and separates by gravity.
View details →
Fine bubbles released from saturated water lift dispersed oil and solids to the surface for skimming.
View details →
Eductors, diverter plates and deflector plates distributing gas through the cell to float oil out of the water.
View details →
An IGF cell fitted with an internal coalescer pack, improving removal of the finer oil droplets.
View details →
Nutshell media polishing the stream to low oil-in-water levels ahead of discharge or injection.

Bulk oil first, then flotation, then polishing — each stage sized for the droplets the previous one leaves behind.
Distributing inlet flow evenly across the cell so no part of the vessel is short-circuited.
Drawing gas into the water and dispersing it as fine bubbles without rotating equipment.
Internal media merging fine droplets into larger ones that separate more readily.
Controlling flow direction through the cell to maximise contact time.
Nutshell media beds with backwash, polishing to tight oil-in-water limits.
Trains configured against the applicable overboard or reinjection specification.
Multiple stages combined on a single skid where footprint allows.
Capacity set by the produced water rate expected across field life, not just at start-up.
Project experience
Produced water and sour water treatment supplied within early production and gas processing facilities.
