Oil Separators

oildropHydroflux Industrial offers a comprehensive range of high quality stainless steel oil water separators designed specifically for tradewaste treatment or to remove oil from storm water run off

In many industrial applications free oil removal is a requisite prior to any other form of treatment. The Hydroflux HySEP.TW Oil Separator is a device designed to separate gross amounts of free oil present in industrial wastewater as a preliminary stage to other forms of treatment. Applications include oil refineries, chemical plants, natural gas processing plants and other industrial sources.

For storm water treatment from electrical substations, tank farms and other areas where storm water run off is contaminated with oil, the Hydroflux HySEP.SW will remove virtually all oil allowing water to be safely discharged to the environment. For zero oil discharge in environmentally sensitive areas, the Hydroflux HySEP.SWZ range out performs other units.

The Hydroflux Oil separator is a parallel plate separator whereby it uses a specially designed oleophilic plate pack to increase the effective surface area of the separation vessel. This increased surface area provides more surface for oil droplets to coalesce and enhance the separation process.

Oil Separator Principals

The Hy-SEP.TW separator is a gravity separation device designed to remove free oil from water. When oil is present in the water phase, it exists in droplets of various sizes. As oil generally has a specific gravity less than that of water, the oil will rise to the surface. The rate at which the oil rises is calculated by applying Stokes Law. This formula calculates the rise rate of a given oil droplet based on the droplet size, the specific gravity and viscosity of the medium

Our Services


Engaging a professional wastewater treatment company to look after the entire wastewater project is aconvenient, economical and hassle free option for industry.

Hydroflux Industrial can provide all process design works, manufacture and fabrication, construction and even complete operation of your wastewater treatment plant.

When Hydroflux Industrial provides complete solutions, we can either undertake a contract on a turnkey basis or work together with building services engineers and other construction professionals such as architects, structural engineers and quantity surveyors to ensure that the project is delivered smoothly, without interruption and on time.


The Hydroflux Group is able to offer a Build Operate & Transfer (BOT) option for water and wastewater assets in Australia and New Zealand. This innovative partnership arrangement strengthens existing strong bonds between Hydroflux and their customers for the long term.

Hydroflux, represented by a special purpose vehicle dedicated to the project, supplies the design, construction, financing, and operation of the water or wastewater plant. The plant is transferred to the client at the end of the contract, which is generally around 10 years.

Hydroflux also purchase existing water and wastewater plants on a similar basis, which releases cash to our clients for either returning or distributing to investors or for funding other investments in their core business.

The multidisciplinary structure of the Hydroflux group including design, construction, equipment supply and operation makes Hydroflux the ideal BOT water and wastewater partner.

Please contact Hydroflux if would like to explore the option of either acquiring a new water or wastewater facility without capital outlay or would like to free up cash by selling your existing water or wastewater assets.

Hydroflux product solutions are fully equipped, ready for operation. This complete offer allows clients to consider the best technical solutions available via the most efficient process
