Commercial Applications

During the past 10 years great changes have impacted the wastewater treatment industry, no more so than the focus on nutrient export into the environment from treated waste streams. This has seen the once acceptable 20/30/30 standard replaced by a desired 10/10/10/10 outcome, which has in turn seen more sophisticated treatment plants designed and built with a noticeable emphasis on those with the ability to reduce Nitrogen and Phosphorus.

Initially these have been predominantly IDEA or trickle filter type processes, which due to their very design have created issues relative to sludge management, covering aspects such as plant complexity, ongoing sludge removal, the cost thereof and manpower requirements.

Many of our customers saw these issues in a negative light, as in many cases their requirements were for small to medium sized applications.

In 2002 we became aware of this niche in the 400,000 litres per day and below market, and over the past 2-3 years have developed a hybrid activated sludge plant capable of enhanced biological Nitrogen removal.

This has been achieved by taking and modifying traditional technologies, using up to date information relative to the biology involved and combining these with state of the art plant and equipment.

The plants are designed to operate for 2-3 years before sludge management issues may arise, and when that time does arrive, a relatively inexpensive desludging of the first receiving chamber may be all that is necessary.

Routine service & maintenance visits are also kept to a minimum, and are specified according to the type and volume of wastewater treated. Most plants only require routine visits 4 times per annum.


In addition to the lack of complexity and the associated ongoing costs, the Plants have the following benefits:-

  • Normally housed in a poured-on-site concrete tank/s for greater robustness and superior aesthetics.

  • Can be located in-ground to 100mm from top of tank.

  • All electrical panels fabricated in Stainless Steel for longevity.

  • All electrical components have back-up units to ensure seamless operation in the event of equipment failure.

  • All 3-phase equipment has phase protection to avoid damage during power fluctuations.

  • All 3-phase equipment will automatically restart after power fluctuations cease.

  • Each Plant has back to base telephone communication to alert the service provider to any fault or failure.

  • Once commissioned, are designed to 'set and forget'.

  • Can be pressurised to allow location in sensitive areas.
