Rotary Above Ground

In industrial applications, screening is essential as the first stage of treatment to remove bulk solids that would otherwise increase the solids and organic load on downstream plant.

Hydroflux Industrial can supply many different forms of screenings systems using various types of media and aperture size with each screen being selected based on the application, the solids load, type of solids and the hydraulic profile.

The development, selection and supply of screens is maintained in-house utilising one of a range of products from Hydroflux HUBER or Hydroflux Technology. In industrial applications above ground rotary type screens are the most commonly utilised however below ground rotary in-channel screens are often a cost effective option if the hydraulic profile permits. Hydroflux Industrial can also offer screenings compaction and dewatering systems to reduce the volume of waste to be disposed of.

The HUBER Rotary Drum Screen RoMesh® consists of a horizontal screen basket equipped with a fine square mesh (0.2 to 1 mm mesh size) or a perforated plate (2 to 3 mm perforation). Due to the two-dimensional effect of the mesh or perforated plate the screen removes very fine particulate material.
The wastewater flows from inside to outside the basket through the rotating screen surface. Filtrate (screened effluent) is discharged vertically from the bottom of the drum and the screenings are transported horizontally by the rotation of the screen and discharged into a screenings bin for disposal.

A spray bar with alternately operating spray nozzles cleans the screen surface while the drum rotates. Optional hot water or high pressure sprays can be supplied for high grease and fat load applications.

Hydroflux Industrial supply a comprehensive range of above ground screens to suit virtually any industrial application

Engaging a professional wastewater treatment company to look after the entire wastewater project is a convenient, 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 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.
