EnviroSEP™ Technology
Ovivo’s EnviroSEP™ units provide oil and water separation for a multitude of industrial wastewater, process water pre-treatment and stormwater treatment applications. The unit is designed to remove all free oil from contaminated streams to comply with the most stringent of discharge requirements. Typically, no more than 5mg/l of oil will remain, with no visible sheen.
Ovivo’s unique two-stage plate pack ensures high performance at all times. The first stage is designed to remove gross slugs of oil and is followed by the secondary polishing stage, which removes any remaining droplets. This ensures that the treated water contains no traces of free visible oil.
All of Ovivo’s EnviroSEP units are designed with an internal oil tank, preventing the need for unsightly drums or other containers to collect separated oil. The integrated oil tank control system also acts as a shut-off mechanism to prevent failure in the event of neat oil entering the unit.
All models are fitted with several drainage points to facilitate cleaning and solids removal. Unlike many other units, the cleaning process for EnviroSEP units does not require full drainage, nor is it necessary to remove the plate pack.
Ovivo teams are also specialists in the design and construction of custom-built systems, including containerized oil separators.
The EnviroSEP design incorporates many features to maximize the performance of the unit. These include: laminar flow conditions (achieved by specially designed inlet distribution baffles); uniform distribution throughout the oil separator plate pack; materials that attract oil and encourage coalescing; 60-degree plate pack angling to maximize solids removal and reduce maintenance.

The plate packs are fabricated from flat stainless steel sheets, configured to maximize coalescing of oil droplets. The plate pack will never warp or corrode, ensuring performance for the life of the unit.

The inlet strainer basket, supplied as standard in all EnviroSEP units, is designed to prevent any possibility of plate pack blockages. The basket is easily removed for cleaning.
All of the EnviroSEP units are manufactured in stainless steel. High grades of stainless steel are available to suit more corrosive applications
The EnviroSEP unit and all of its components are manufactured in stainless steel to the highest quality standards. All equipment and materials are extremely reliable and often designed to withstand remote and unattended locations.

The EnviroSEP unit is fitted with a major spill protection cut-off security system which, following a major spillage, automatically stops the feed to the unit within a matter of minutes. This feature ensures optimum performance under any influent conditions.
