High Performance

WyunaSep liquid /liquid hydrocyclones can treat emulsions with oil droplets below 20 microns. (100 to 150 microns for competitor's systems). More reliable oil separation performance. Units are not affected by debris build up or inadequate maintenance, as can occur with other systems. The treatment system is closed hence there are no equipment smells or vapour emissions.

Low Maintenance


No plates, or Hopper to clean leading to lower yearly maintenance costs. No closely packed plates to block. No algae chemical dose required. No large stagnant volumes. All our systems use high quality stainless steel piping and frames. No occupational health & safety issues like with plate pack cleaning.

Easy Installation/Use

Our most models are easily manoeuvrable and will fit into confined or hazardous spaces.Pressurized oil and water discharge allows flexibility in site location and savings because re-pumping is not required. Standard systems are fully pneumatic with no electrical connections. This greatly simplifies and reduces the cost of installation.

Operational Flexibility

Has the ability (via recycle option) to batch treat very difficult emulsions, and discharge water when oil content is below limits. With low cost recycle option, equipment has the ability to meet future oil discharge limits without additional capital expenditure. Removed oil is stored in large above (or below) ground decanting containers, extending the time between oil waste collections.

Because our systems use skimmers, oil layers do not accumulate in the effluent pit so little or no oil will escape if the pit accidentally floods.

Feature, Which Means?

Foot Print

Compact, 10% the size and weight of conventional systems. -2 to 24 m3 = 1 to 1.5 m2 area.

Oil content

single cycle 20 ppm or recycle + DHRR 5ppm in two stage Clean water with no chemicals. Effluent can be recycled for continuous treatment.

It is the most economical.

Lowest cleaning & maintenance bills. Lowest repair & parts replacement bills. Lowest total ownership cost over 2 to 4 years.
