Odours and wastewater are almost synonymous – where there is one you will often find the other.

Controlling odours from wastewater, whether found in municipal sewer systems or industrial wastewater treatment plants, is achieved by either eliminating the cause or where this is not possible, by treating the odours.

The first step in this often challenging problem is always a thorough review of the cause of the odour.

It may well be something simple like stagnant solids that have built up in the base or on the sides of tanks, the upstream chemistry, or the effluent may simply smell bad because of what it contains.

Improved maintenance, better mixing, and/or a different operating pH may be the solution.

However, this is often not the case, especially if the effluent simply smells bad because of what it contains or the control solution is simply impractical.

In this case an odour capture and treatment system is necessary.

Traditional odour control systems have been around for a long time and unfortunately they also have a lot of down sides.

Carbon absorption systems require expensive media replacement and disposal, liquid scrubbers use large volumes of expensive chemicals and produce yet more effluent, and bio-filtration systems take months to start working, take up a large area of land and again produce more effluent to treat.

Internationally, especially in Europe, these technologies are rapidly being phased out and replaced by modern photoionisation odour control systems.

These photoionisation systems are incredibly compact, operate without chemicals, do not produce effluent and do not work by absorption. They also work the moment they are turned on.

The NEUTRALOX® Photoionisation odour control process is now available in Australia and New Zealand via Hydroflux.

Designed and manufactured in Germany and supported exclusively by Hydroflux this low energy and sustainable odour control process is the best of breed and set to replace the older unsustainable and expensive technologies.

Hydroflux Industrial’s Mathew Pugh said, “With over 400 installations overseas, the NEUTRALOX® Photoionisation Process is the preferred odour control system due to its obvious advantages over traditional odour treatment technologies.

“I often see bio-filters used on industrial sites because that was the only technology available. But they take up a large amount of space, are an eyesore and are expensive to run.

“With a footprint that is often less than one tenth of a bio-filter for the same application, along with its all stainless steel exterior and with all operating components contained inside the unit the NEUTRALOX® Photoionisation Process is by far the better option”.

This revolutionary technology can be used to control odours originating from waste, wastewater, sewage and sludge-treatment processes.

Essentially based on the application of high intensity UV-light and using specialised catalysts, in addition to highly effective odour reduction the process has the added bonus of providing extensive air disinfection.

The system can also treat odours immediately after its turned on, as it uses switch-on-switch-off functionality to reduce operating costs and the long term maintenance requirements.

“The system eliminates virtually all odours – achieving odour-reduction rates in excess of 99 per cent – typically providing between 300 and 400 odour units which is well below the 500 odour units typically required” Mr Pugh said.

Hydroflux Industrial, a wholly-owned subsidiary of the Hydroflux Group, has entered into an exclusive agreement to distribute this advanced odour control solution throughout Australia and New Zealand.

Hydroflux Industrial’s agreement with NEUTRALOX Umwelttechnik GmbH further boosts the Hydroflux Group’s portfolio of products for industrial and municipal markets.
